Bitbucket Pipeline Runner

Tool to run Bitbucket Pipelines locally.

Installation

The prefered way of installing pipeline-runner is with pipx

pipx install bitbucket-pipeline-runner

Basic usage

To run a pipeline

cd <project-directory>
pipeline-runner run <pipeline-name>

To list available pipelines

cd <project-directory>
pipeline-runner list

Environment variables

bitbucket pipeline runner already sets all BITBUCKET_* environment variables in the step's run environment. It will also source any .env file in the current directory, for all project specific environment variables.

Artifacts and logs

Persistent data like artifacts generated from your pipelines and execution logs can be found in your user's data directory.

On Linux:

${XDG_DATA_HOME:-~/.local/share}/pipeline-runner

On macOS:

~/Library/Application Support/pipeline-runner

Caches

Caches defined in your pipelines are stored in your user's cache directory. Unlike Bitbucket Pipelines, caches are always saved even if they already exists. This is subject to change in the future, to follow the behaviour of Bitbucket Pipelines.

On Linux:

${XDG_CACHE_HOME:-~/.cache}/pipeline-runner

On macOS:

~/Library/Caches/pipeline-runner

Note: Docker cache is stored in a docker volume instead.

Debugging

A few features are available to help with debugging.

Breakpoints

Breakpoints, or pauses, can be added during the execution of a pipeline. To do so, add a # pipeline-runner[breakpoint] entry in script like so

    example_with_breakpoint:
      - step:
          name: Step with breakpoint
          script:
            - echo "do something"
            - # pipeline-runner[breakpoint]
            - echo "do something else"

The execution will stop at the breakpoint to allow the user to check the state of the pipeline.

CPU Limits Enforcing

By default, no cpu limits are enforced, meaning that the pipeline will run as fast as it can. You can mimick the cpu limits enforced by Bitbucket Pipelines with the --cpu-limits. This is useful to replicate more closely the speed at which a pipeline runs in the real thing.
