drone-gcf - a Google Cloud Function plugin for drone.io

Feb, 2019

Google Cloud Funtions allow you to execute small pieces of code, written in NodeJS, Python or Golang and whenever a certain event is triggered. The events can be e.g. a HTTP request, a message published to PubSub, a file uploaded to GCS and so on.

The drone.io CI/CD server is a simple yet powerful and extendable Continuous Delivery platform that supports a plugin architecture where plugins a re supplied as docker images.

https://github.com/oliver006/drone-gcf is a plugin that supports managing Cloud Functions as part of a drone CI/CD pipeline. For isntance, it allows you to first run a set of tests and, if successful, publish a new version of your code as a Cloud Function.

See the drone pipeline below for an example of a Golang pipeline that runs tests when new code is pushed and publishes the function when code is merged into master:

kind: pipeline
name: default

  - name: test
    image: golang
      - "go test -v"
        - push

  - name: deploy-cloud-functions
    image: oliver006/drone-gcf
      action: deploy
      project: myproject
        from_secret: token
      runtime: go111
