How to use output of one step in input of other steps?

[sudhanshug16]

Hi, I am wondering how we can use output of one step as the input of subsequent steps?

I came across env_vars but that does not seem to work for plugins it seems. I wanna have the following workflow:

when:
  event: push
  branch: feature/rails-image-woodpecker

steps:
  - name: check-and-duplicate-cache
    image: alpine
    environment:
      REGISTRY_USERNAME:
        from_secret: REGISTRY_USERNAME
      REGISTRY_PASSWORD:
        from_secret: REGISTRY_PASSWORD
    commands:
      - |
        CACHE_IMAGE_TAG=myregistry.example.com/myproject/rails:cache-${CI_COMMIT_BRANCH//\//_}
          if ! curl -s -f -lL -u $REGISTRY_USERNAME:$REGISTRY_PASSWORD "https://myregistry.example.com/v2/myproject/rails/manifests/$CACHE_IMAGE_TAG"; then
          echo "Cache image not found, attempting to pull cache-main"
          CACHE_IMAGE_TAG=myregistry.example.com/myproject/rails:cache-main
        fi
        echo "CACHE_IMAGE_TAG=$CACHE_IMAGE_TAG >> env_vars"

  - name: build-rails-image
    image: woodpeckerci/plugin-docker-buildx
    settings:
      repo: myregistry.example.com/myproject/rails
      tag: ${CI_COMMIT_BRANCH//\//_}
      dockerfile: apps/rails/Dockerfile
      auto_tag: true
      logins:
        - registry: myregistry.example.com
          username:
            from_secret: REGISTRY_USERNAME
          password:
            from_secret: REGISTRY_PASSWORD
      cache_from:
        - $CACHE_IMAGE_TAG
      cache_to:
        - type=registry,ref=$CACHE_IMAGE_TAG,mode=max,image-manifest=true,oci-mediatypes=true

But this does not seem to be possible because I would need to source the env_vars file using a command which is not allowed for plugins.

To me, it seems to be a very basic requirement for a CI/CD pipeline - am I missing something? Github actions has https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/passing-information-between-jobs and I am looking for something like this in woodpecker.

Thanks in advance!

Nope, #2266.

Fork and patch the plugin, whether it would be env file or some json/yaml.

Yes I saw that discussion. I guess I will wait :)

Can we close this as duplicate?
