How do I use Docker variables in Travis CI?

You can use Docker variables in Travis CI by defining them in your .travis.yml file under the 'services' section.

Can you give me an example of how to set that up?

Sure! Here's a simple example:

services:
  - docker

before_install:
  - docker pull your-image:latest

script:
  - docker run your-image:latest

What if I need to pass environment variables to the Docker container?

You can pass environment variables using the -e flag in the docker run command. For example:

script:
  - docker run -e MY_VAR=value your-image:latest

Is there a way to use secrets in Travis CI with Docker?

Yes, you can use Travis CI's encrypted environment variables to store secrets and pass them to your Docker container.
