-# How to Contribute
-
-CNI is [Apache 2.0 licensed](LICENSE) and accepts contributions via GitHub
-pull requests. This document outlines some of the conventions on development
-workflow, commit message formatting, contact points and other resources to make
-it easier to get your contribution accepted.
-
-We gratefully welcome improvements to documentation as well as to code.
-
-# Certificate of Origin
-
-By contributing to this project you agree to the Developer Certificate of
-Origin (DCO). This document was created by the Linux Kernel community and is a
-simple statement that you, as a contributor, have the legal right to make the
-contribution. See the [DCO](DCO) file for details.
-
-# Email and Chat
-
-The project uses the the cni-dev email list and IRC chat:
-- Email: [cni-dev](https://groups.google.com/forum/#!forum/cni-dev)
-- IRC: #[containernetworking](irc://irc.freenode.org:6667/#containernetworking) channel on freenode.org
-
-Please avoid emailing maintainers found in the MAINTAINERS file directly. They
-are very busy and read the mailing lists.
-
-## Getting Started
-
-- Fork the repository on GitHub
-- Read the [README](README.md) for build and test instructions
-- Play with the project, submit bugs, submit pull requests!
-
-## Contribution workflow
-
-This is a rough outline of how to prepare a contribution:
-
-- Create a topic branch from where you want to base your work (usually branched from master).
-- Make commits of logical units.
-- Make sure your commit messages are in the proper format (see below).
-- Push your changes to a topic branch in your fork of the repository.
-- If you changed code, make sure the tests pass, and add any new tests as appropriate.
-- Make sure any new code files have a license header.
-- Submit a pull request to the original repository.
-
-# Acceptance policy
-
-These things will make a PR more likely to be accepted:
-
- * a well-described requirement
- * tests for new code
- * tests for old code!
- * new code follows the conventions in old code
- * a good commit message (see below)
-
-In general, we will merge a PR once two maintainers have endorsed it.
-Trivial changes (e.g., corrections to spelling) may get waved through.
-For substantial changes, more people may become involved, and you might get asked to resubmit the PR or divide the changes into more than one PR.
-
-### Format of the Commit Message
-
-We follow a rough convention for commit messages that is designed to answer two
-questions: what changed and why. The subject line should feature the what and
-the body of the commit should describe the why.
-
-```
-scripts: add the test-cluster command
-
-this uses tmux to setup a test cluster that you can easily kill and
-start for debugging.
-
-Fixes #38
-```
-
-The format can be described more formally as follows:
-
-```
-<subsystem>: <what changed>
-<BLANK LINE>
-<why this change was made>
-<BLANK LINE>
-<footer>
-```
-
-The first line is the subject and should be no longer than 70 characters, the
-second line is always blank, and other lines should be wrapped at 80 characters.
-This allows the message to be easier to read on GitHub as well as in various
-git tools.

-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its

-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or

-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.

-      agreed to in writing, Licensor provides the Work (and each

-# CNI - the Container Network Interface
-
-## What is CNI?
-
-The CNI (_Container Network Interface_) project consists of a specification and libraries for writing plugins to configure network interfaces in Linux containers, along with a number of supported plugins.
-CNI concerns itself only with network connectivity of containers and removing allocated resources when the container is deleted.
-Because of this focus, CNI has a wide range of support and the specification is simple to implement.
-
-As well as the [specification](SPEC.md), this repository contains the Go source code of a library for integrating CNI into applications, an example command-line tool, a template for making new plugins, and the supported plugins.
-
-The template code makes it straight-forward to create a CNI plugin for an existing container networking project.
-CNI also makes a good framework for creating a new container networking project from scratch.
-
-## Why develop CNI?
-
-Application containers on Linux are a rapidly evolving area, and within this area networking is not well addressed as it is highly environment-specific.
-We believe that many container runtimes and orchestrators will seek to solve the same problem of making the network layer pluggable.
-
-To avoid duplication, we think it is prudent to define a common interface between the network plugins and container execution: hence we put forward this specification, along with libraries for Go and a set of plugins.
-

-## Contributing to CNI
-
-We welcome contributions, including [bug reports](https://github.com/containernetworking/cni/issues), and code and documentation improvements.
-If you intend to contribute to code or documentation, please read [CONTRIBUTING.md](CONTRIBUTING.md). Also see the [contact section](#contact) in this README.
-
-## How do I use CNI?
-
-### Requirements
-
-CNI requires Go 1.5+ to build.
-
-Go 1.5 users will need to set GO15VENDOREXPERIMENT=1 to get vendored
-dependencies. This flag is set by default in 1.6.
-
-### Included Plugins
-
-This repository includes a number of common plugins in the `plugins/` directory.
-Please see the [Documentation/](Documentation/) directory for documentation about particular plugins.
-
-### Running the plugins
-
-The scripts/ directory contains two scripts, `priv-net-run.sh` and `docker-run.sh`, that can be used to exercise the plugins.
-
-**note - priv-net-run.sh depends on `jq`**
-
-Start out by creating a netconf file to describe a network:
-
-```bash
-$ mkdir -p /etc/cni/net.d
-$ cat >/etc/cni/net.d/10-mynet.conf <<EOF
-{
-	"name": "mynet",
-	"type": "bridge",
-	"bridge": "cni0",
-	"isGateway": true,
-	"ipMasq": true,
-	"ipam": {
-		"type": "host-local",
-		"subnet": "10.22.0.0/16",
-		"routes": [
-			{ "dst": "0.0.0.0/0" }
-		]
-	}
-}
-EOF
-$ cat >/etc/cni/net.d/99-loopback.conf <<EOF
-{
-	"type": "loopback"
-}
-EOF
-```
-
-The directory `/etc/cni/net.d` is the default location in which the scripts will look for net configurations.
-
-Next, build the plugins:
-
-```bash
-$ ./build
-```
-
-Finally, execute a command (`ifconfig` in this example) in a private network namespace that has joined the `mynet` network:
-
-```bash
-$ CNI_PATH=`pwd`/bin
-$ cd scripts
-$ sudo CNI_PATH=$CNI_PATH ./priv-net-run.sh ifconfig
-eth0      Link encap:Ethernet  HWaddr f2:c2:6f:54:b8:2b  
-          inet addr:10.22.0.2  Bcast:0.0.0.0  Mask:255.255.0.0
-          inet6 addr: fe80::f0c2:6fff:fe54:b82b/64 Scope:Link
-          UP BROADCAST MULTICAST  MTU:1500  Metric:1
-          RX packets:1 errors:0 dropped:0 overruns:0 frame:0
-          TX packets:0 errors:0 dropped:1 overruns:0 carrier:0
-          collisions:0 txqueuelen:0 
-          RX bytes:90 (90.0 B)  TX bytes:0 (0.0 B)
-
-lo        Link encap:Local Loopback  
-          inet addr:127.0.0.1  Mask:255.0.0.0
-          inet6 addr: ::1/128 Scope:Host
-          UP LOOPBACK RUNNING  MTU:65536  Metric:1
-          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
-          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
-          collisions:0 txqueuelen:0 
-          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
-```
-
-The environment variable `CNI_PATH` tells the scripts and library where to look for plugin executables.
-
-## Running a Docker container with network namespace set up by CNI plugins
-
-Use the instructions in the previous section to define a netconf and build the plugins.
-Next, docker-run.sh script wraps `docker run`, to execute the plugins prior to entering the container:
-
-```bash
-$ CNI_PATH=`pwd`/bin
-$ cd scripts
-$ sudo CNI_PATH=$CNI_PATH ./docker-run.sh --rm busybox:latest ifconfig
-eth0      Link encap:Ethernet  HWaddr fa:60:70:aa:07:d1  
-          inet addr:10.22.0.2  Bcast:0.0.0.0  Mask:255.255.0.0
-          inet6 addr: fe80::f860:70ff:feaa:7d1/64 Scope:Link
-          UP BROADCAST MULTICAST  MTU:1500  Metric:1
-          RX packets:1 errors:0 dropped:0 overruns:0 frame:0
-          TX packets:0 errors:0 dropped:1 overruns:0 carrier:0
-          collisions:0 txqueuelen:0 
-          RX bytes:90 (90.0 B)  TX bytes:0 (0.0 B)
-
-lo        Link encap:Local Loopback  
-          inet addr:127.0.0.1  Mask:255.0.0.0
-          inet6 addr: ::1/128 Scope:Host
-          UP LOOPBACK RUNNING  MTU:65536  Metric:1
-          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
-          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
-          collisions:0 txqueuelen:0 
-          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
-```
-
-## What might CNI do in the future?
-
-CNI currently covers a wide range of needs for network configuration due to it simple model and API.
-However, in the future CNI might want to branch out into other directions:
-
-- Dynamic updates to existing network configuration
-- Dynamic policies for network bandwidth and firewall rules
-
-If these topics of are interest, please contact the team via the mailing list or IRC and find some like-minded people in the community to put a proposal together.

-# Container Networking Interface Proposal
-
-## Overview
-
-This document proposes a generic plugin-based networking solution for application containers on Linux, the _Container Networking Interface_, or _CNI_.
-It is derived from the [rkt Networking Proposal][rkt-networking-proposal], which aimed to satisfy many of the [design considerations][rkt-networking-design] for networking in [rkt][rkt-github].
-
-For the purposes of this proposal, we define two terms very specifically:
-- _container_ can be considered synonymous with a [Linux _network namespace_][namespaces]. What unit this corresponds to depends on a particular container runtime implementation: for example, in implementations of the [App Container Spec][appc-github] like rkt, each _pod_ runs in a unique network namespace. In [Docker][docker], on the other hand, network namespaces generally exist for each separate Docker container.
-- _network_ refers to a group of entities that are uniquely addressable that can communicate amongst each other. This could be either an individual container (as specified above), a machine, or some other network device (e.g. a router). Containers can be conceptually _added to_ or _removed from_ one or more networks.

-[appc-github]: https://github.com/appc/spec
-[docker]: https://docker.com 
-
-## General considerations
-
-The intention is for the container runtime to first create a new network namespace for the container.
-It then determines which networks this container should belong to and for each network, which plugin must be executed.
-The network configuration is in JSON format and can easily be stored in a file.
-The network configuration includes mandatory fields such as "name" and "type" as well as plugin (type) specific ones.
-The network configuration allows for fields to change values between invocations. For this purpose there is an optional field "args" which should contain the varying information.
-The container runtime sequentially sets up the networks by executing the corresponding plugin for each network.
-Upon completion of the container lifecycle, the runtime executes the plugins in reverse order (relative to the order in which they were added) to disconnect them from the networks.
-
-## CNI Plugin
-
-### Overview
-
-Each CNI plugin is implemented as an executable that is invoked by the container management system (e.g. rkt or Docker).
-
-A CNI plugin is responsible for inserting a network interface into the container network namespace (e.g. one end of a veth pair) and making any necessary changes on the host (e.g. attaching other end of veth into a bridge).
-It should then assign the IP to the interface and setup the routes consistent with IP Address Management section by invoking appropriate IPAM plugin.
-
-### Parameters
-
-The operations that the CNI plugin needs to support are:
-
-
-- Add container to network
-  - Parameters:
-    - **Version**. The version of CNI spec that the caller is using (container management system or the invoking plugin).
-    - **Container ID**. This is optional but recommended, and should be unique across an administrative domain while the container is live (it may be reused in the future). For example, an environment with an IPAM system may require that each container is allocated a unique ID and that each IP allocation can thus be correlated back to a particular container. As another example, in appc implementations this would be the _pod ID_.
-    - **Network namespace path**. This represents the path to the network namespace to be added, i.e. /proc/[pid]/ns/net or a bind-mount/link to it.
-    - **Network configuration**. This is a JSON document describing a network to which a container can be joined. The schema is described below.
-    - **Extra arguments**. This provides an alternative mechanism to allow simple configuration of CNI plugins on a per-container basis.
-    - **Name of the interface inside the container**. This is the name that should be assigned to the interface created inside the container (network namespace); consequently it must comply with the standard Linux restrictions on interface names.
-  - Result:
-    - **IPs assigned to the interface**. This is either an IPv4 address, an IPv6 address, or both.
-    - **DNS information**. Dictionary that includes DNS information for nameservers, domain, search domains and options.
-
-- Delete container from network
-  - Parameters:
-    - **Version**. The version of CNI spec that the caller is using (container management system or the invoking plugin).
-    - **Container ID**, as defined above.
-    - **Network namespace path**, as defined above.
-    - **Network configuration**, as defined above.
-    - **Extra arguments**, as defined above.
-    - **Name of the interface inside the container**, as defined above.
-
-The executable command-line API uses the type of network (see [Network Configuration](#network-configuration) below) as the name of the executable to invoke.
-It will then look for this executable in a list of predefined directories. Once found, it will invoke the executable using the following environment variables for argument passing:
-- `CNI_VERSION`:  [Semantic Version 2.0](http://semver.org) of CNI specification. This effectively versions the CNI_XXX environment variables.
-- `CNI_COMMAND`: indicates the desired operation; either `ADD` or `DEL`
-- `CNI_CONTAINERID`: Container ID
-- `CNI_NETNS`: Path to network namespace file
-- `CNI_IFNAME`: Interface name to set up
-- `CNI_ARGS`: Extra arguments passed in by the user at invocation time. Alphanumeric key-value pairs separated by semicolons; for example, "FOO=BAR;ABC=123"
-- `CNI_PATH`: Colon-separated list of paths to search for CNI plugin executables
-
-Network configuration in JSON format is streamed to the plugin through stdin. This means it is not tied to a particular file on disk and can contain information which changes between invocations.
-
-
-### Result
-
-Success is indicated by a return code of zero and the following JSON printed to stdout in the case of the ADD command. This should be the same output as was returned by the IPAM plugin (see [IP Allocation](#ip-allocation) for details).
-
-```
-{
-  "cniVersion": "0.1.0",
-  "ip4": {
-    "ip": <ipv4-and-subnet-in-CIDR>,
-    "gateway": <ipv4-of-the-gateway>,  (optional)
-    "routes": <list-of-ipv4-routes>    (optional)
-  },
-  "ip6": {
-    "ip": <ipv6-and-subnet-in-CIDR>,
-    "gateway": <ipv6-of-the-gateway>,  (optional)
-    "routes": <list-of-ipv6-routes>    (optional)
-  },
-  "dns": {
-    "nameservers": <list-of-nameservers>           (optional)
-    "domain": <name-of-local-domain>               (optional)
-    "search": <list-of-additional-search-domains>  (optional)
-    "options": <list-of-options>                   (optional)
-  }
-}
-```
-
-`cniVersion` specifies a [Semantic Version 2.0](http://semver.org) of CNI specification used by the plugin.
-`dns` field contains a dictionary consisting of common DNS information that this network is aware of.
-The result is returned in the same format as specified in the [configuration](#network-configuration).
-The specification does not declare how this information must be processed by CNI consumers.
-Examples include generating an `/etc/resolv.conf` file to be injected into the container filesystem or running a DNS forwarder on the host.
-
-Errors are indicated by a non-zero return code and the following JSON being printed to stdout:
-```
-{
-  "cniVersion": "0.1.0",
-  "code": <numeric-error-code>,
-  "msg": <short-error-message>,
-  "details": <long-error-message> (optional)
-}
-```
-
-`cniVersion` specifies a [Semantic Version 2.0](http://semver.org) of CNI specification used by the plugin.
-Error codes 0-99 are reserved for well-known errors (see [Well-known Error Codes](#well-known-error-codes) section).
-Values of 100+ can be freely used for plugin specific errors. 
-
-In addition, stderr can be used for unstructured output such as logs.
-
-### Network Configuration
-
-The network configuration is described in JSON form. The configuration can be stored on disk or generated from other sources by the container runtime. The following fields are well-known and have the following meaning:
-- `cniVersion` (string): [Semantic Version 2.0](http://semver.org) of CNI specification to which this configuration conforms.
-- `name` (string): Network name. This should be unique across all containers on the host (or other administrative domain).
-- `type` (string): Refers to the filename of the CNI plugin executable.
-- `args` (dictionary): Optional additional arguments provided by the container runtime. For example a dictionary of labels could be passed to CNI plugins by adding them to a labels field under `args`.
-- `ipMasq` (boolean): Optional (if supported by the plugin). Set up an IP masquerade on the host for this network. This is necessary if the host will act as a gateway to subnets that are not able to route to the IP assigned to the container.
-- `ipam`: Dictionary with IPAM specific values:
-  - `type` (string): Refers to the filename of the IPAM plugin executable.
-  - `routes` (list): List of subnets (in CIDR notation) that the CNI plugin should ensure are reachable by routing them through the network. Each entry is a dictionary containing:
-    - `dst` (string): subnet in CIDR notation
-    - `gw` (string): IP address of the gateway to use. If not specified, the default gateway for the subnet is assumed (as determined by the IPAM plugin).
-- `dns`: Dictionary with DNS specific values:
-  - `nameservers` (list of strings): list of a priority-ordered list of DNS nameservers that this network is aware of. Each entry in the list is a string containing either an IPv4 or an IPv6 address.
-  - `domain` (string): the local domain used for short hostname lookups.
-  - `search` (list of strings): list of priority ordered search domains for short hostname lookups. Will be preferred over `domain` by most resolvers.
-  - `options` (list of strings): list of options that can be passed to the resolver
-
-Plugins may define additional fields that they accept and may generate an error if called with unknown fields. The exception to this is the `args` field may be used to pass arbitrary data which may be ignored by plugins.

-As part of its operation, a CNI plugin is expected to assign (and maintain) an IP address to the interface and install any necessary routes relevant for that interface. This gives the CNI plugin great flexibility but also places a large burden on it. Many CNI plugins would need to have the same code to support several IP management schemes that users may desire (e.g. dhcp, host-local). 
-
-To lessen the burden and make IP management strategy be orthogonal to the type of CNI plugin, we define a second type of plugin -- IP Address Management Plugin (IPAM plugin). It is however the responsibility of the CNI plugin to invoke the IPAM plugin at the proper moment in its execution. The IPAM plugin is expected to determine the interface IP/subnet, Gateway and Routes and return this information to the "main" plugin to apply. The IPAM plugin may obtain the information via a protocol (e.g. dhcp), data stored on a local filesystem, the "ipam" section of the Network Configuration file or a combination of the above.
-
-#### IP Address Management (IPAM) Interface
-
-Like CNI plugins, the IPAM plugins are invoked by running an executable. The executable is searched for in a predefined list of paths, indicated to the CNI plugin via `CNI_PATH`. The IPAM Plugin receives all the same environment variables that were passed in to the CNI plugin. Just like the CNI plugin, IPAM receives the network configuration via stdin.
-
-Success is indicated by a zero return code and the following JSON being printed to stdout (in the case of the ADD command):
-
-```
-{
-  "cniVersion": "0.1.0",
-  "ip4": {
-    "ip": <ipv4-and-subnet-in-CIDR>,
-    "gateway": <ipv4-of-the-gateway>,  (optional)
-    "routes": <list-of-ipv4-routes>    (optional)
-  },
-  "ip6": {
-    "ip": <ipv6-and-subnet-in-CIDR>,
-    "gateway": <ipv6-of-the-gateway>,  (optional)
-    "routes": <list-of-ipv6-routes>    (optional)
-  },
-  "dns": {
-    "nameservers": <list-of-nameservers>           (optional)
-    "domain": <name-of-local-domain>               (optional)
-    "search": <list-of-search-domains>             (optional)
-    "options": <list-of-options>                   (optional)
-  }
-}
-```
-
-`cniVersion` specifies a [Semantic Version 2.0](http://semver.org) of CNI specification used by the plugin.
-`gateway` is the default gateway for this subnet, if one exists.
-It does not instruct the CNI plugin to add any routes with this gateway: routes to add are specified separately via the `routes` field.
-An example use of this value is for the CNI plugin to add this IP address to the linux-bridge to make it a gateway.
-
-Each route entry is a dictionary with the following fields:
-- `dst` (string): Destination subnet specified in CIDR notation.
-- `gw` (string): IP of the gateway. If omitted, a default gateway is assumed (as determined by the CNI plugin).
-
-The "dns" field contains a dictionary consisting of common DNS information. 
-- `nameservers` (list of strings): list of a priority-ordered list of DNS nameservers that this network is aware of. Each entry in the list is a string containing either an IPv4 or an IPv6 address.
-- `domain` (string): the local domain used for short hostname lookups.
-- `search` (list of strings): list of priority ordered search domains for short hostname lookups. Will be preferred over `domain` by most resolvers.
-- `options` (list of strings): list of options that can be passed to the resolver
-See [CNI Plugin Result](#result) section for more information.
-
-Errors and logs are communicated in the same way as the CNI plugin. See [CNI Plugin Result](#result) section for details.
-
-IPAM plugin examples:
- - **host-local**: Select an unused (by other containers on the same host) IP within the specified range.
- - **dhcp**: Use DHCP protocol to acquire and maintain a lease. The DHCP requests will be sent via the created container interface; therefore, the associated network must support broadcast.
-
-#### Notes
- - Routes are expected to be added with a 0 metric.
- - A default route may be specified via "0.0.0.0/0". Since another network might have already configured the default route, the CNI plugin should be prepared to skip over its default route definition.
-
-## Well-known Error Codes
-- `1` - Incompatible CNI version
-- `2` - Unsupported field in network configuration. The error message must contain the key and value of the unsupported field.

-### Namespaces, Threads, and Go
-On Linux each OS thread can have a different network namespace.  Go's thread scheduling model switches goroutines between OS threads based on OS thread load and whether the goroutine would block other goroutines.  This can result in a goroutine switching network namespaces without notice and lead to errors in your code.
-
-### Namespace Switching
-Switching namespaces with the `ns.Set()` method is not recommended without additional strategies to prevent unexpected namespace changes when your goroutines switch OS threads.
-
-Go provides the `runtime.LockOSThread()` function to ensure a specific goroutine executes on its current OS thread and prevents any other goroutine from running in that thread until the locked one exits.  Careful usage of `LockOSThread()` and goroutines can provide good control over which network namespace a given goroutine executes in.
-
-For example, you cannot rely on the `ns.Set()` namespace being the current namespace after the `Set()` call unless you do two things.  First, the goroutine calling `Set()` must have previously called `LockOSThread()`.  Second, you must ensure `runtime.UnlockOSThread()` is not called somewhere in-between.  You also cannot rely on the initial network namespace remaining the current network namespace if any other code in your program switches namespaces, unless you have already called `LockOSThread()` in that goroutine.  Note that `LockOSThread()` prevents the Go scheduler from optimally scheduling goroutines for best performance, so `LockOSThread()` should only be used in small, isolated goroutines that release the lock quickly.
-
-### Do() The Recommended Thing
-The `ns.Do()` method provides control over network namespaces for you by implementing these strategies. All code dependent on a particular network namespace should be wrapped in the `ns.Do()` method to ensure the correct namespace is selected for the duration of your code.  For example:
-
-```go
-targetNs, err := ns.NewNS()
-if err != nil {
-    return err
-}
-err = targetNs.Do(func(hostNs ns.NetNS) error {
-	dummy := &netlink.Dummy{
-		LinkAttrs: netlink.LinkAttrs{
-			Name: "dummy0",
-		},
-	}
-	return netlink.LinkAdd(dummy)
-})
-```

-# host-local IP address manager
-
-host-local IPAM allocates IPv4 and IPv6 addresses out of a specified address range.
-
-## Usage
-
-### Obtain an IP
-
-Given the following network configuration:
-
-```
-{
-    "name": "default",
-    "ipam": {
-        "type": "host-local",
-        "subnet": "203.0.113.0/24"
-    }
-}
-```
-
-#### Using the command line interface
-
-```
-$ export CNI_COMMAND=ADD
-$ export CNI_CONTAINERID=f81d4fae-7dec-11d0-a765-00a0c91e6bf6
-$ ./host-local < $conf
-```
-
-```
-{
-    "ip4": {
-        "ip": "203.0.113.1/24"
-    }
-}
-```
-
-## Backends
-
-By default ipmanager stores IP allocations on the local filesystem using the IP address as the file name and the ID as contents. For example:
-
-```
-$ ls /var/lib/cni/networks/default
-```
-```
-203.0.113.1	203.0.113.2
-```
-
-```
-$ cat /var/lib/cni/networks/default/203.0.113.1
-```
-```
-f81d4fae-7dec-11d0-a765-00a0c91e6bf6
-```
-
-## Configuration Files
-
-
-```
-{
-	"name": "ipv6",
-    "ipam": {
-		"type": "host-local",
-		"subnet": "3ffe:ffff:0:01ff::/64",
-		"range-start": "3ffe:ffff:0:01ff::0010",

-		"routes": [
-			{ "dst": "3ffe:ffff:0:01ff::1/64" }
-		]
-	}
-}
-```
-
-```
-{
-    "name": "ipv4",
-	"ipam": {
-		"type": "host-local",
-		"subnet": "203.0.113.1/24",

-
-Go bindings for iptables utility.
-
-In-kernel netfilter does not have a good userspace API. The tables are manipulated via setsockopt that sets/replaces the entire table. Changes to existing table need to be resolved by userspace code which is difficult and error-prone. Netfilter developers heavily advocate using iptables utlity for programmatic manipulation.
-
-go-iptables wraps invokation of iptables utility with functions to append and delete rules; create, clear and delete chains.

-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
