drone-gae

Manage deployments on Google App Engine via drone

This plugin is a simple wrapper around the appcfg.py and gcloud app commands, which makes it capable of making deployments with Go, PHP or Python projects in the standard enviroment or any language in the flexible environment.

The action configruation variable (shown below) can accept any action that you would normally call on appcfg.py or gcloud app. So far, it has been tested with update to deploy and set_default_version to migrate traffic in appcfg and gcloud app deploy for gcloud app, but it should also be capable of running helpful ops commands like update_indexes and update_cron.

To see a full list of configuration settings for the project, check out the GAE struct declaration.

This is currently using gcloud version 145.0.0 and App Engine SDK version 1.9.48.

Examples

Basic example of capable of deploying a new version of a Go, PHP and Python 'hello, world' application to standard App Engine.

deploy:
  gae:
    action: update
    project: my-gae-project
    version: "$$COMMIT"
    token: >
      $$GOOGLE_CREDENTIALS
    when:
      event: push
      branch: master

Testing, deploying and migrating traffic to a Go application.

build:
  image: jprobinson/ae-go-buildbox:1.6
  commands:
    - goapp get -t
    - goapp test -v -cover
  when:
    event:
      - push
      - pull_request

deploy:

  # deploy new version to App Engine
  gae:
    image: nytimes/drone-gae
    environment:
      - GOPATH=/drone
    action: update
    project: my-gae-project
    version: "$$COMMIT"
    ae_environment:
      MY_SECRET: $$MY_SECRET_DEV
    token: >
      $$GOOGLE_CREDENTIALS
    when:
      event: push
      branch: master

  # set new version to 'default', which migrates 100% traffic.
  gae:
    image: nytimes/drone-gae
    action: set_default_version
    project: my-gae-project
    version: "$$COMMIT"
    token: >
      $$GOOGLE_CREDENTIALS
    when:
      event: push
      branch: master

Deploying multiple applications from the same git repository using the 'dir' option:

deploy:

  # deploy new version of the 'frontend' service to App Engine
  gae:
    image: nytimes/drone-gae
    action: update
    project: my-gae-project
    version: "$$COMMIT"
    dir: frontend
    token: >
      $$GOOGLE_CREDENTIALS
    when:
      event: push
      branch: master

  # deploy new version of the 'api' service to App Engine
  gae:
    image: nytimes/drone-gae
    action: update
    project: my-gae-project
    version: "$$COMMIT"
    dir: api
    token: >
      $$GOOGLE_CREDENTIALS
    when:
      event: push
      branch: master

Deploying an application to dev via pushes to master and to prd via git tags:

deploy:

  # deploy new version of the service to App Engine on every commit to master
  # to a 'dev' project using a specific yaml file.
  gae:
    image: nytimes/drone-gae
    action: update
    project: my-dev-project
    version: "$$COMMIT"
    app_file: dev.yaml
    token: >
      $$GOOGLE_CREDENTIALS_DEV
    when:
      event: push
      branch: master

  # deploy new version of the service to App Engine on every git tag
  # to a 'prd' project using a specific yaml file.
  gae:
    image: nytimes/drone-gae
    action: update
    project: my-prd-project
    version: "$$COMMIT"
    app_file: prd.yaml
    token: >
      $$GOOGLE_CREDENTIALS_PRD
    when:
      event: tag

Building a Docker image, pushing it to GCR and then deploying it via gcloud app deploy:

build:
  image: jprobinson/ae-go-buildbox:1.6
  environment:
    - GOPATH=/drone
  commands:
    - go test -v -race ./...
    - go build -o api .
  when:
    event:
      - push
      - pull_request

# runs `docker build` and `docker push` to the specified GCR
publish:
  gcr:
    repo: my-gae-project/api
    tag: "$$COMMIT"
    token: >
       $$GOOGLE_CREDENTIALS_DEV
    storage_driver: overlay
    when:
      branch: [develop, master]
      event: push

deploy:

  # deploy a new version using the docker image we just published and stop any previous versions when complete.
  gae:
    image: nytimes/drone-gae
    action: deploy
    project: my-gae-project
    flex_image: gcr.io/my-gae-project/puzzles-sub:$$COMMIT
    version: "$${COMMIT:0:10}"
    addl_flags:
     - --stop-previous-version
    token: >
      $$GOOGLE_CREDENTIALS_LAB
    when:
      event: push
      branch: develop
