// Package context provides several utilities for working with
// golang.org/x/net/context in http requests. Primarily, the focus is on
// logging relevant request information but this package is not limited to
// that purpose.
//
// The easiest way to get started is to get the background context:
//
// ctx := context.Background()
//
// The returned context should be passed around your application and be the
// root of all other context instances. If the application has a version, this
// line should be called before anything else:
//
// ctx := context.WithVersion(context.Background(), version)
//
// The above will store the version in the context and will be available to
// the logger.
//
// Logging
//
// The most useful aspect of this package is GetLogger. This function takes
// any context.Context interface and returns the current logger from the
// context. Canonical usage looks like this:
//
// GetLogger(ctx).Infof("something interesting happened")
//
// GetLogger also takes optional key arguments. The keys will be looked up in
// the context and reported with the logger. The following example would
// return a logger that prints the version with each log message:
//
// ctx := context.Context(context.Background(), "version", version)
// GetLogger(ctx, "version").Infof("this log message has a version field")
//
// The above would print out a log message like this:
//
// INFO[0000] this log message has a version field version=v2.0.0-alpha.2.m
//
// When used with WithLogger, we gain the ability to decorate the context with
// loggers that have information from disparate parts of the call stack.
// Following from the version example, we can build a new context with the
// configured logger such that we always print the version field:
//
// ctx = WithLogger(ctx, GetLogger(ctx, "version"))
//
// Since the logger has been pushed to the context, we can now get the version
// field for free with our log messages. Future calls to GetLogger on the new
// context will have the version field:
//
// GetLogger(ctx).Infof("this log message has a version field")
//
// This becomes more powerful when we start stacking loggers. Let's say we
// have the version logger from above but also want a request id. Using the
// context above, in our request scoped function, we place another logger in
// the context:
//
// ctx = context.WithValue(ctx, "http.request.id", "unique id") // called when building request context
// ctx = WithLogger(ctx, GetLogger(ctx, "http.request.id"))
//
// When GetLogger is called on the new context, "http.request.id" will be
// included as a logger field, along with the original "version" field:
//
// INFO[0000] this log message has a version field http.request.id=unique id version=v2.0.0-alpha.2.m
//
// Note that this only affects the new context, the previous context, with the
// version field, can be used independently. Put another way, the new logger,
// added to the request context, is unique to that context and can have
// request scoped varaibles.
//
// HTTP Requests
//
// This package also contains several methods for working with http requests.
// The concepts are very similar to those described above. We simply place the
// request in the context using WithRequest. This makes the request variables
// available. GetRequestLogger can then be called to get request specific
// variables in a log line:
//
// ctx = WithRequest(ctx, req)
// GetRequestLogger(ctx).Infof("request variables")
//
// Like above, if we want to include the request data in all log messages in
// the context, we push the logger to a new context and use that one:
//
// ctx = WithLogger(ctx, GetRequestLogger(ctx))
//
// The concept is fairly powerful and ensures that calls throughout the stack
// can be traced in log messages. Using the fields like "http.request.id", one
// can analyze call flow for a particular request with a simple grep of the
// logs.

The Moby Project
================
![Moby Project logo](docs/static_files/moby-project-logo.png "The Moby Project")
Moby is an open-source project created by Docker to advance the software containerization movement.
It provides a “Lego set” of dozens of components, the framework for assembling them into custom container-based systems, and a place for all container enthusiasts to experiment and exchange ideas.
Moby is an open-source project created by Docker to enable and accelerate software containerization.
# Moby
## Overview
At the core of Moby is a framework to assemble specialized container systems.
It provides:
- A library of containerized components for all vital aspects of a container system: OS, container runtime, orchestration, infrastructure management, networking, storage, security, build, image distribution, etc.
- Tools to assemble the components into runnable artifacts for a variety of platforms and architectures: bare metal (both x86 and Arm); executables for Linux, Mac and Windows; VM images for popular cloud and virtualization providers.
- A set of reference assemblies which can be used as-is, modified, or used as inspiration to create your own.
All Moby components are containers, so creating new components is as easy as building a new OCI-compatible container.
It provides a "Lego set" of toolkit components, the framework for assembling them into custom container-based systems, and a place for all container enthusiasts and professionals to experiment and exchange ideas.
Components include container build tools, a container registry, orchestration tools, a runtime and more, and these can be used as building blocks in conjunction with other tools and projects.
## Principles
Moby is an open project guided by strong principles, but modular, flexible and without too strong an opinion on user experience, so it is open to the community to help set its direction.
The guiding principles are:
Moby is an open project guided by strong principles, aiming to be modular, flexible and without too strong an opinion on user experience.
It is open to the community to help set its direction.
- Modular: the project includes lots of components that have well-defined functions and APIs that work together.
- Batteries included but swappable: Moby includes enough components to build fully featured container system, but its modular architecture ensures that most of the components can be swapped by different implementations.
- Usable security: Moby will provide secure defaults without compromising usability.
- Container centric: Moby is built with containers, for running containers.
With Moby, you should be able to describe all the components of your distributed application, from the high-level configuration files down to the kernel you would like to use and build and deploy it easily.
Moby uses [containerd](https://github.com/containerd/containerd) as the default container runtime.
- Usable security: Moby provides secure defaults without compromising usability.
- Developer focused: The APIs are intended to be functional and useful to build powerful tools.
They are not necessarily intended as end user tools but as components aimed at developers.
Documentation and UX is aimed at developers not end users.
## Audience
Moby is recommended for anyone who wants to assemble a container-based system. This includes:
The Moby Project is intended for engineers, integrators and enthusiasts looking to modify, hack, fix, experiment, invent and build systems based on containers.
It is not for people looking for a commercially supported system, but for people who want to work and learn with open source code.
- Hackers who want to customize or patch their Docker build
- System engineers or integrators building a container system
- Infrastructure providers looking to adapt existing container systems to their environment
- Container enthusiasts who want to experiment with the latest container tech
- Open-source developers looking to test their project in a variety of different systems
- Anyone curious about Docker internals and how it’s built
## Relationship with Docker
Moby is NOT recommended for:
The components and tools in the Moby Project are initially the open source components that Docker and the community have built for the Docker Project.
New projects can be added if they fit with the community goals. Docker is committed to using Moby as the upstream for the Docker Product.
However, other projects are also encouraged to use Moby as an upstream, and to reuse the components in diverse ways, and all these uses will be treated in the same way. External maintainers and contributors are welcomed.
- Application developers looking for an easy way to run their applications in containers. We recommend Docker CE instead.
- Enterprise IT and development teams looking for a ready-to-use, commercially supported container platform. We recommend Docker EE instead.
- Anyone curious about containers and looking for an easy way to learn. We recommend the [docker.com](https://www.docker.com/) website instead.
# Transitioning to Moby
Docker is transitioning all of its open source collaborations to the Moby project going forward.
During the transition, all open source activity should continue as usual.
We are proposing the following list of changes:
- splitting up the engine into more open components
- removing the docker UI, SDK etc to keep them in the Docker org
- clarifying that the project is not limited to the engine, but to the assembly of all the individual components of the Docker platform
- open-source new tools & components which we currently use to assemble the Docker product, but could benefit the community
- defining an open, community-centric governance inspired by the Fedora project (a very successful example of balancing the needs of the community with the constraints of the primary corporate sponsor)
The Moby project is not intended as a location for support or feature requests for Docker products, but as a place for contributors to work on open source code, fix bugs, and make the code more useful.
The releases are supported by the maintainers, community and users, on a best efforts basis only, and are not intended for customers who want enterprise or commercial support; Docker EE is the appropriate product for these use cases.

There are two make files, each with different extensions. Neither are supposed
to be called directly; only invoke `make`. Both scripts run inside a Docker
container.
### make.ps1
- The Windows native build script that uses PowerShell semantics; it is limited
unlike `hack\make.sh` since it does not provide support for the full set of
operations provided by the Linux counterpart, `make.sh`. However, `make.ps1`
does provide support for local Windows development and Windows to Windows CI.
More information is found within `make.ps1` by the author, @jhowardmsft
### make.sh
- Referenced via `make test` when running tests on a local machine,
or directly referenced when running tests inside a Docker development container.
- When running on a local machine, `make test` to run all tests found in
`test`, `test-unit`, `test-integration`, and `test-docker-py` on
your local machine. The default timeout is set in `make.sh` to 60 minutes
(`${TIMEOUT:=60m}`), since it currently takes up to an hour to run
all of the tests.
- When running inside a Docker development container, `hack/make.sh` does
not have a single target that runs all the tests. You need to provide a
single command line with multiple targets that performs the same thing.
An example referenced from [Run targets inside a development container](https://docs.docker.com/opensource/project/test-and-docs/#run-targets-inside-a-development-container): `root@5f8630b873fe:/go/src/github.com/moby/moby# hack/make.sh dynbinary binary cross test-unit test-integration test-docker-py`
- For more information related to testing outside the scope of this README,
refer to
[Run tests and test documentation](https://docs.docker.com/opensource/project/test-and-docs/)
## Release (release.sh)
Releases any bundles built by `make` on a public AWS S3 bucket.
For information regarding configuration, please view `release.sh`.
## Vendor (vendor.sh)
A shell script that is a wrapper around Vndr. For information on how to use
this, please refer to [vndr's README](https://github.com/LK4D4/vndr/blob/master/README.md)

# Integration Testing on Swarm
IT on Swarm allows you to execute integration test in parallel across a Docker Swarm cluster
## Architecture
### Master service
- Works as a funker caller
- Calls a worker funker (`-worker-service`) with a chunk of `-check.f` filter strings (passed as a file via `-input` flag, typically `/mnt/input`)
### Worker service
- Works as a funker callee
- Executes an equivalent of `TESTFLAGS=-check.f TestFoo|TestBar|TestBaz ... make test-integration-cli` using the bind-mounted API socket (`docker.sock`)
### Client
- Controls master and workers via `docker stack`
- No need to have a local daemon
Typically, the master and workers are supposed to be running on a cloud environment,
while the client is supposed to be running on a laptop, e.g. Docker for Mac/Windows.
## Requirement
- Docker daemon 1.13 or later
- Private registry for distributed execution with multiple nodes
## Usage
### Step 1: Prepare images
$ make build-integration-cli-on-swarm
Following environment variables are known to work in this step:
- `BUILDFLAGS`
- `DOCKER_INCREMENTAL_BINARY`
Note: during the transition into Moby Project, you might need to create a symbolic link `$GOPATH/src/github.com/docker/docker` to `$GOPATH/src/github.com/moby/moby`.
### Step 2: Execute tests
$ ./hack/integration-cli-on-swarm/integration-cli-on-swarm -replicas 40 -push-worker-image YOUR_REGISTRY.EXAMPLE.COM/integration-cli-worker:latest
Following environment variables are known to work in this step:
- `DOCKER_GRAPHDRIVER`
- `DOCKER_EXPERIMENTAL`
#### Flags
Basic flags:
- `-replicas N`: the number of worker service replicas. i.e. degree of parallelism.
- `-chunks N`: the number of chunks. By default, `chunks` == `replicas`.
- `-push-worker-image REGISTRY/IMAGE:TAG`: push the worker image to the registry. Note that if you have only single node and hence you do not need a private registry, you do not need to specify `-push-worker-image`.
Experimental flags for mitigating makespan nonuniformity:
- `-shuffle`: Shuffle the test filter strings
Flags for debugging IT on Swarm itself:
- `-rand-seed N`: the random seed. This flag is useful for deterministic replaying. By default(0), the timestamp is used.
- `-filters-file FILE`: the file contains `-check.f` strings. By default, the file is automatically generated.
- `-dry-run`: skip the actual workload
- `keep-executor`: do not auto-remove executor containers, which is used for running privileged programs on Swarm

pkg/ is a collection of utility packages used by the Docker project without being specific to its internals.
Utility packages are kept separate from the docker core codebase to keep it as small and concise as possible.
If some utilities grow larger and their APIs stabilize, they may be moved to their own repository under the
Docker organization, to facilitate re-use by other projects. However that is not the priority.
The directory `pkg` is named after the same directory in the camlistore project. Since Brad is a core
Go maintainer, we thought it made sense to copy his methods for organizing Go code :) Thanks Brad!
Because utility packages are small and neatly separated from the rest of the codebase, they are a good
place to start for aspiring maintainers and contributors. Get in touch if you want to help maintain them!
