# libcompose

[![GoDoc](https://godoc.org/github.com/docker/libcompose?status.png)](https://godoc.org/github.com/docker/libcompose)

[![Build Status](https://jenkins.dockerproject.org/job/docker/job/libcompose/branch/master/badge/icon)](https://jenkins.dockerproject.org/job/docker/job/libcompose/branch/master/)

A Go library for Docker Compose. It does everything the command-line tool does, but from within Go -- read Compose files, start them, scale them, etc.

**Note: This is not really maintained anymore — the reason are diverse but mainly lack of time from the maintainers**

The current state is the following :

- The `libcompose` CLI should considered abandonned. The `v2` parsing is incomplete and `v3` parsing is missing.

- The official compose Go parser implementation is on [`docker/cli`](https://github.com/docker/cli/tree/master/cli/compose) but only support `v3` version of the compose format.

What is the work that is needed:

- Remove the cli code (thus removing dependencies to `docker/cli` )

- Clearer separation of packages : `parsing`, `conversion` (to docker api or swarm api), `execution` (`Up`, `Down`, … behaviors)

- Add support for all compose format version (v1, v2.x, v3.x)

- Switch to either `golang/dep` or `go mod` for dependencies (removing the `vendor` folder)

- *(bonus)* extract the [`docker/cli`](https://github.com/docker/cli/tree/master/cli/compose) code here and vendor this library into `docker/cli`.

If you are interested to work on `libcompose`, feel free to ping me (over twitter @vdemeest), I'll definitely do code reviews and help as much as I can 😉.

**Note: This is experimental and not intended to replace the [Docker Compose](https://github.com/docker/compose) command-line tool. If you're looking to use Compose, head over to the [Compose installation instructions](http://docs.docker.com/compose/install/) to get started with it.**

## Usage

```go

package main

import (

	"log"

	"golang.org/x/net/context"

	"github.com/docker/libcompose/docker"

	"github.com/docker/libcompose/docker/ctx"

	"github.com/docker/libcompose/project"

	"github.com/docker/libcompose/project/options"

)

func main() {

	project, err := docker.NewProject(&ctx.Context{

		Context: project.Context{

			ComposeFiles: []string{"docker-compose.yml"},

			ProjectName:  "my-compose",

		},

	}, nil)

	if err != nil {

		log.Fatal(err)

	}

	err = project.Up(context.Background(), options.Up{})

	if err != nil {

		log.Fatal(err)

	}

}

```

## Building

You need either [Docker](http://github.com/docker/docker) and `make`,

or `go` in order to build libcompose.

### Building with `docker`

You need Docker and ``make`` and then run the ``binary`` target. This

will create binary for all platform in the `bundles` folder.

```bash

$ make binary

docker build -t "libcompose-dev:refactor-makefile" .

# […]

---> Making bundle: binary (in .)

Number of parallel builds: 4

-->      darwin/386: github.com/docker/libcompose/cli/main

-->    darwin/amd64: github.com/docker/libcompose/cli/main

-->       linux/386: github.com/docker/libcompose/cli/main

-->     linux/amd64: github.com/docker/libcompose/cli/main

-->       linux/arm: github.com/docker/libcompose/cli/main

-->     windows/386: github.com/docker/libcompose/cli/main

-->   windows/amd64: github.com/docker/libcompose/cli/main

$ ls bundles

libcompose-cli_darwin-386*    libcompose-cli_linux-amd64*      libcompose-cli_windows-amd64.exe*

libcompose-cli_darwin-amd64*  libcompose-cli_linux-arm*

libcompose-cli_linux-386*     libcompose-cli_windows-386.exe*

```

### Building with `go`

- You need `go` v1.11 or greater

- you need to set export `GO111MODULE=on` environment variable

- If your working copy is not in your `GOPATH`, you need to set it

accordingly.

```bash

$ go generate

# Generate some stuff

$ go build -o libcompose ./cli/main

```

## Running

A partial implementation of the libcompose-cli CLI is also implemented in Go. The primary purpose of this code is so one can easily test the behavior of libcompose.

Run one of these:

```

libcompose-cli_darwin-386

libcompose-cli_linux-amd64

libcompose-cli_windows-amd64.exe

libcompose-cli_darwin-amd64

libcompose-cli_linux-arm

libcompose-cli_linux-386

libcompose-cli_windows-386.exe

```

## Tests (unit & integration)

You can run unit tests using the `test-unit` target and the

integration test using the `test-integration` target. If you don't use

Docker and `make` to build `libcompose`, you can use `go test` and the

following scripts : `hack/test-unit` and `hack/test-integration`.

```bash

$ make test-unit

docker build -t "libcompose-dev:refactor-makefile" .

#[…]

---> Making bundle: test-unit (in .)

+ go test -cover -coverprofile=cover.out ./docker

+ go test -cover -coverprofile=cover.out ./version

ok      github.com/docker/libcompose/version    0.002s  coverage: 0.0% of statements

Test success

```
