Docker Commands in Your Builds

You can run Docker commands as a part of your build process by adding them to your build spec. However, Docker is not enabled by default.

Enable Docker

To enable Docker:

• You’ll need to be on one of our paid plans.
• Your builds need to be using one of our General Purpose build images.

Contact us and let us know which service needs to have it enabled.

Running LocalStack on Seed

Once you’ve got Docker enabled, you can run tests using LocalStack on Seed by adding something like the following in your seed.yml.

before_compile:
  - >
    docker run -d --rm
    -p 4567-4608:4567-4608
    -e DOCKER_HOST=unix:///var/run/docker.sock
    -v /tmp/localstack:/tmp/localstack
    -v /var/run/docker.sock:/var/run/docker.sock
    localstack/localstack
