How do I set up a basic Travis CI configuration for a Docker project?

To set up a basic Travis CI configuration for a Docker project, you'll need to create a .travis.yml file in your repository.

What should I include in the .travis.yml file?

You should include the language, services, and the script to build your Docker image. Here's a simple example:

language: generic
services:
  - docker
script:
  - docker build -t my-image .

How do I push the Docker image to Docker Hub?

You can add a deploy section in your .travis.yml file like this:

deploy:
  provider: docker
  username: your_dockerhub_username
  password: $DOCKERHUB_PASSWORD
  image: your_dockerhub_username/my-image
