How to run docker-compose on AWS CodeBuild?

Okay, I figured out the issue!

You need to enable 'Privileged Access' on the CodeBuild container. This will allow you to interact with the docker cli.

Then add these two lines to the install commands:

- nohup /usr/local/bin/dockerd --host=unix:///var/run/docker.sock --host=tcp://127.0.0.1:2375 --storage-driver=overlay2& - timeout 15 sh -c "until docker info; do echo .; sleep 1; done" `

ex:

version: 0.2

phases:
  install:
    commands:
      - nohup /usr/local/bin/dockerd --host=unix:///var/run/docker.sock --host=tcp://127.0.0.1:2375 --storage-driver=overlay2&
      - timeout 15 sh -c "until docker info; do echo .; sleep 1; done"
  pre_build:
    commands:
      - docker build -t helloworld .
  build:
    commands:
      - docker images
      - docker run helloworld echo "Hello, World!"

Are you using the Docker runtime for your build environment?

I am working with this repo: https://github.com/mreferre/yelb

That dockercompose isn't building anything (it's rather meant to deploy) but I believe you are hitting a problem much before that. Your compose up should work if you use the Docker runtime.

This is what my buildspec looks like:

version: 0.2
phases:
  build:
    commands:
        - cd deployments/platformdeployment/Docker
        - docker-compose up -d

And this is the output:
