Welcome to Woodpecker

Woodpecker is a simple, yet powerful CI/CD 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.yaml

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

steps:
  - name: build
    image: debian
    commands:
      - echo "This is the build step"
  - name: 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:
   - name: 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

steps:
  - name: build
    image: debian
    commands:
      - touch myfile
  - name: 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

FROM laszlocloud/kubectl
COPY deploy /usr/local/deploy
ENTRYPOINT ["/usr/local/deploy"]

kubectl apply -f $PLUGIN_TEMPLATE

steps:
  - name: deploy-to-k8s
    image: laszlocloud/my-k8s-plugin
    settings:
      template: config/k8s/service.yaml

See plugin docs.
