How can I use Docker Compose with Travis CI?

You can use Docker Compose in Travis CI by defining your services in a docker-compose.yml file and using the services key in your .travis.yml.

Can you show me a sample .travis.yml file?

Sure! Here's a basic example:

language: generic
services:
  - docker
before_install:
  - docker-compose up -d
script:
  - docker-compose run app test

What if I need to run tests in a specific service?

You can specify the service in the docker-compose run command. For example:

script:
  - docker-compose run service_name test

Is there a way to cache Docker layers in Travis CI?

Yes, you can cache Docker layers by using the cache key in your .travis.yml file. Here's an example:

cache:
  directories:
    - /var/lib/docker
