Bitbucket Pipelines is an integrated CI/CD solution that allows specifying Docker containers and commands to run for each branch. It integrates with Bitbucket repositories and configures via a bitbucket-pipelines.yml file. Compared to Drone.io, it has longer build times per user, customizable builds per branch, and integrates with the Bitbucket UI. The documentation demonstrates configuring pipeline steps and debugging locally by running commands in a Docker container.
