Container Builder GitHub CI connector for Google Cloud Functions

Cloud Function to use the PubSub events on the cloud-builds topic to update GitHub CI status.

This function is designed to work with GitHub repositories mirrored under Google Cloud Source Control named github-${config.repoOwner}-${ghRepoName}. If you set this through the Container Builder build trigger UI, this will be named automatically.

Deploy

Generate a new token with the repo:status OAuth scope.

Set the following on config in index.js:

• ciUser
• ciAccessToken
• repoOwner

Deploy the cloud function to gcloud:

gcloud beta functions deploy setCIStatus --trigger-topic cloud-builds

Kudos Deploy (gcb)

The above are the manual steps, the preferred approach is to deploy the function through the pipeline in Google Cloud Build.

A trigger has been manually set up to run a terraform script in order to apply changes to the Google Cloud Function every time a code change is pushed to master in this repository.

The trigger configuration includes two environment variables that are used by terraform. One of them, GITHUB_TOKEN, is used by the function itself and it is provided setting an enviroment variable for the function. The variables defined in the trigger are:

1. GITHUB_TOKEN: you can find it in the info.txt file in gocrypto-fs looking for the word GITHUB_CI_TOKEN_GCB
2. PROJECT_ID: provided by gcb.

Alternative Kudos Deploy (local machine)

export GITHUB_CI_TOKEN_GCB= make deploy

Behavior

CI Status context will be one of:

• ${projectId}/gcb: ${tags.join('/')}
• ${projectId}/gcb: ${id.substring(0,8)}

Use the tags field in your build request to name your CI. Otherwise, it falls back to the build-GUID.

CI Status description will either be:

• nothing
• a join of all images to be published: gcr.io/project/image:v1 gcr.io/project/image:latest
• above all, the duration of the build: 3m 27s
• possibly with the last-running build step and error status: 3m 27s · test failure
