Meli is supposed to be a faster alternative to docker-compose. Faster in the sense that, Meli will try to pull as many services(docker containers) as it can in parallel.

Meli is a Swahili word meaning ship; so think of Meli as a ship carrying your docker containers safely across the treacherous container seas.

It's currently work in progress, API will remain unstable for sometime.

I only intend to support docker-compose version 3+

Meli is NOT intended to replicate every feature of docker-compose, it is primarily intended to enable you to pull, build and run the services in your docker-compose file as fast as possible.
If you want to exec in to a running container, use docker; if you want to run an adhoc command in a container, use docker; if you want..... you get the drift.


Download a binary release for your particular OS from the releases page
We have binaries for:

  • linux(32bit and 64bit)
  • windows(32bit and 64bit)
  • darwin(32bit and 64bit)
    Optionally, you can install using curl;
curl -sfL | sh


meli --help

Usage of meli:
    	Builds, re/creates, starts, and attaches to containers for a service.
        -d option runs containers in the background
  -f string
    	path to docker-compose.yml file. (default "docker-compose.yml")
  -v	Show version information.
    	Show version information.

cat docker-compose.yml

version: '3'
    image: 'redis:3.0-alpine'
      - RACK_ENV=development
      - type=database

Usage as a library

You really should be using the official docker Go sdk
However, if you feel inclined to use meli;

package main

import (


func main() {
	dc := &api.DockerContainer{
		ComposeService: api.ComposeService{Image: "busybox"},
		LogMedium:      os.Stdout,
		FollowLogs:     true}

	ctx := context.Background()
	cli, err := client.NewEnvClient()
	if err != nil {
		log.Fatal(err, " :unable to intialize docker client")
	defer cli.Close()

	api.GetAuth() // read dockerhub info
	err = api.PullDockerImage(ctx, cli, dc)



Aaah, everyones' favorite vanity metric yet no one seems to know how to conduct one in a consistent and scientific manner.
Take any results you see here with a large spoon of salt; They are unscientific and reek of all that is wrong with most developer benchmarks.

Having made that disclaimer,

test machine:
This circleCI machine

docker-compose version:
docker-compose --version

docker-compose version 1.17.1, build 6d101fb

Meli version:
version 0.1.1

Benchmark test:
this docker-compose file

Benchmark script:
for docker-compose:
docker ps -aq | xargs docker rm -f; docker system prune -af; /usr/bin/time -apv docker-compose up -d
for meli:
docker ps -aq | xargs docker rm -f; docker system prune -af; /usr/bin/time -apv meli -up -d

Benchmark results(average):

tool Elapsed wall clock time(seconds)
docker-compose 10.411 seconds
meli 3.945 seconds

Thus, meli appears to be 2.6 times faster than docker-compose(by wall clock time).
You can checkout the current benchmark results from circleCI
However, I'm not making a tool to take docker-compose to the races.


git clone
go build -o meli main.go
./meli -up -f /path/to/docker-compose-file.yml


  • add better documentation(godoc)
  • stabilise API(maybe)
