Welcome to Woodpecker

Woodpecker is a simple CI engine with great extensibility. It focuses on executing pipelines inside containers. If you are already using containers in your daily workflow, you'll for sure love Woodpecker.

.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
steps:
  build:
    image: debian
    commands:
      - echo "This is the build step"
  a-test-step:
    image: debian
    commands:
      - echo "Testing.."

Steps are containers​

  • Define any container image as context
    • either use your own and install the needed tools in a custom image
    • or search for available images that are already tailored for your needs in image registries like Docker Hub
  • List the commands that should be executed in the container
steps:
  build:
-   image: debian
+   image: mycompany/image-with-awscli
    commands:
      - aws help

File changes are incremental​

  • Woodpecker clones the source code in the beginning
  • File changes are persisted throughout individual steps as the same volume is being mounted in all steps
# .woodpecker.yml
steps:
  build:
    image: debian
    commands:
      - touch myfile
  a-test-step:
    image: debian
    commands:
      - cat myfile

Plugins are straightforward​

  • 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
# Dockerfile
FROM laszlocloud/kubectl
COPY deploy /usr/local/deploy
ENTRYPOINT ["/usr/local/deploy"]
# deploy
kubectl apply -f $PLUGIN_TEMPLATE
# .woodpecker.yml
steps:
  deploy-to-k8s:
    image: laszlocloud/my-k8s-plugin
    settings:
      template: config/k8s/service.yml

See plugin docs.
