Welcome to Woodpecker

Woodpecker is a simple CI engine with great extensibility.

.woodpecker.yml

  • Place your pipeline in a file named .woodpecker.yml in your repository
  • Pipeline steps can be named as you like
  • Run any command in the commands section

# .woodpecker.yml
pipeline:
  build:
    image: debian
    commands:
      - echo "This is the build step"
  a-test-step:
    image: debian
    commands:
      - echo "Testing.."

Build steps are containers

  • Define any Docker image as context
  • Install the needed tools in custom Docker images, use them as context

pipeline:
  build:
-    image: debian
+   image: mycompany/image-with-awscli
    commands:
      - aws help

File changes are incremental

  • Woodpecker clones the source code in the beginning pipeline
  • Changes to files are persisted through steps as the same volume is mounted to all steps

Plugins are straighforward

  • If you copy the same shell script from project to project
  • Pack it into a plugin instead
  • And make the yaml declarative
  • Plugins are Docker images with your script as an entrypoint
