# LinuxKit with OpenStack
LinuxKit interacts with OpenStack through its native APIs and requires access
to both an OpenStack Keystone server for authentication and a OpenStack Glance
server in order to host the LinuxKit images.

A compatible/supported image needs to have the correct extension (must match
A compatible image needs to have the correct extension (must match
one from above) in order to be supported by the `linuxkit push openstack`
command. The `openstack` backend will use the filename extension to determine
the image type, and use the filename as a label for the new image.
The `openstack` backend also supports OpenStack projects to provide
multi-tenancy support when uploading images.
### Usage
The `openstack` backend uses the password authentication method in order to
retrieve a token that can be used to interact with the various components of
OpenStack. The URLs for the Keystone/Glance server components need to have
the ports detailed as below.
OpenStack. Example usage:
```
./linuxkit push openstack \
-keystoneAddr=http://keystone.com:5000 \
-authurl=http://keystone.com:5000/v3 \
-username=admin \
-password=XXXXXXXXXXX \
-project=linuxkit \
-glanceAddr=http://glance.com:9292 \
./linuxkit.iso
```
### Execution Flow
1. Log in to OpenStack (Keystone)
2. Retrieve the OpenStack Key from the response header
3. Create a "queued" image on the glance server and return the new image ID
4. Use the new image ID and upload the LinuxKit image under this new ID
1. Authenticate with OpenStack's identity service
2. Create a "queued" image in Glance and retrieve its UUID
3. Use this new image ID to upload the LinuxKit image

# Gophercloud: an OpenStack SDK for Go
[![Build Status](https://travis-ci.org/gophercloud/gophercloud.svg?branch=master)](https://travis-ci.org/gophercloud/gophercloud)
[![Coverage Status](https://coveralls.io/repos/github/gophercloud/gophercloud/badge.svg?branch=master)](https://coveralls.io/github/gophercloud/gophercloud?branch=master)
Gophercloud is an OpenStack Go SDK.
## Useful links
* [Reference documentation](http://godoc.org/github.com/gophercloud/gophercloud)
* [Effective Go](https://golang.org/doc/effective_go.html)
## How to install
Before installing, you need to ensure that your [GOPATH environment variable](https://golang.org/doc/code.html#GOPATH)
is pointing to an appropriate directory where you want to install Gophercloud:
```bash
mkdir $HOME/go
export GOPATH=$HOME/go
```
To protect yourself against changes in your dependencies, we highly recommend choosing a
[dependency management solution](https://github.com/golang/go/wiki/PackageManagementTools) for
your projects, such as [godep](https://github.com/tools/godep). Once this is set up, you can install
Gophercloud as a dependency like so:
```bash
go get github.com/gophercloud/gophercloud
# Edit your code to import relevant packages from "github.com/gophercloud/gophercloud"
godep save ./...
```
This will install all the source files you need into a `Godeps/_workspace` directory, which is
referenceable from your own source files when you use the `godep go` command.
## Getting started
### Credentials
Because you'll be hitting an API, you will need to retrieve your OpenStack
credentials and either store them as environment variables or in your local Go
files. The first method is recommended because it decouples credential
information from source code, allowing you to push the latter to your version
control system without any security risk.
You will need to retrieve the following:
* username
* password
* a valid Keystone identity URL
For users that have the OpenStack dashboard installed, there's a shortcut. If
you visit the `project/access_and_security` path in Horizon and click on the
"Download OpenStack RC File" button at the top right hand corner, you will
download a bash file that exports all of your access details to environment
variables. To execute the file, run `source admin-openrc.sh` and you will be
prompted for your password.
### Authentication
Once you have access to your credentials, you can begin plugging them into
Gophercloud. The next step is authentication, and this is handled by a base
"Provider" struct. To get one, you can either pass in your credentials
explicitly, or tell Gophercloud to use environment variables:
```go
import (
"github.com/gophercloud/gophercloud"
"github.com/gophercloud/gophercloud/openstack"
"github.com/gophercloud/gophercloud/openstack/utils"
)
// Option 1: Pass in the values yourself
opts := gophercloud.AuthOptions{
IdentityEndpoint: "https://openstack.example.com:5000/v2.0",
Username: "{username}",
Password: "{password}",
}
// Option 2: Use a utility function to retrieve all your environment variables
opts, err := openstack.AuthOptionsFromEnv()
```
Once you have the `opts` variable, you can pass it in and get back a
`ProviderClient` struct:
```go
provider, err := openstack.AuthenticatedClient(opts)
```
The `ProviderClient` is the top-level client that all of your OpenStack services
derive from. The provider contains all of the authentication details that allow
your Go code to access the API - such as the base URL and token ID.
### Provision a server
Once we have a base Provider, we inject it as a dependency into each OpenStack
service. In order to work with the Compute API, we need a Compute service
client; which can be created like so:
```go
client, err := openstack.NewComputeV2(provider, gophercloud.EndpointOpts{
Region: os.Getenv("OS_REGION_NAME"),
})
```
We then use this `client` for any Compute API operation we want. In our case,
we want to provision a new server - so we invoke the `Create` method and pass
in the flavor ID (hardware specification) and image ID (operating system) we're
interested in:
```go
import "github.com/gophercloud/gophercloud/openstack/compute/v2/servers"
server, err := servers.Create(client, servers.CreateOpts{
Name: "My new server!",
FlavorRef: "flavor_id",
ImageRef: "image_id",
}).Extract()
```
The above code sample creates a new server with the parameters, and embodies the
new resource in the `server` variable (a
[`servers.Server`](http://godoc.org/github.com/gophercloud/gophercloud) struct).
## Advanced Usage
Have a look at the [FAQ](./FAQ.md) for some tips on customizing the way Gophercloud works.
## Backwards-Compatibility Guarantees
None. Vendor it and write tests covering the parts you use.
## Contributing
See the [contributing guide](./.github/CONTRIBUTING.md).

/*
Package gophercloud provides a multi-vendor interface to OpenStack-compatible
clouds. The library has a three-level hierarchy: providers, services, and
resources.
Provider structs represent the service providers that offer and manage a
collection of services. The IdentityEndpoint is typically refered to as
"auth_url" in information provided by the cloud operator. Additionally,
the cloud may refer to TenantID or TenantName as project_id and project_name.
These are defined like so:
opts := gophercloud.AuthOptions{
IdentityEndpoint: "https://openstack.example.com:5000/v2.0",
Username: "{username}",
Password: "{password}",
TenantID: "{tenant_id}",
}
provider, err := openstack.AuthenticatedClient(opts)
Service structs are specific to a provider and handle all of the logic and
operations for a particular OpenStack service. Examples of services include:
Compute, Object Storage, Block Storage. In order to define one, you need to
pass in the parent provider, like so:
opts := gophercloud.EndpointOpts{Region: "RegionOne"}
client := openstack.NewComputeV2(provider, opts)
Resource structs are the domain models that services make use of in order
to work with and represent the state of API resources:
server, err := servers.Get(client, "{serverId}").Extract()
Intermediate Result structs are returned for API operations, which allow
generic access to the HTTP headers, response body, and any errors associated
with the network transaction. To turn a result into a usable resource struct,
you must call the Extract method which is chained to the response, or an
Extract function from an applicable extension:
result := servers.Get(client, "{serverId}")
// Attempt to extract the disk configuration from the OS-DCF disk config
// extension:
config, err := diskconfig.ExtractGet(result)
All requests that enumerate a collection return a Pager struct that is used to
iterate through the results one page at a time. Use the EachPage method on that
Pager to handle each successive Page in a closure, then use the appropriate
extraction method from that request's package to interpret that Page as a slice
of results:
err := servers.List(client, nil).EachPage(func (page pagination.Page) (bool, error) {
s, err := servers.ExtractServers(page)
if err != nil {
return false, err
}
// Handle the []servers.Server slice.
// Return "false" or an error to prematurely stop fetching new pages.
return true, nil
})
This top-level package contains utility functions and data types that are used
throughout the provider and service packages. Of particular note for end users
are the AuthOptions and EndpointOpts structs.
