Github Actions GCP Deploy Script

This script is used by Git Hub Actions to continuously deploy artifacts to a GCP bucket.

When Git Hub Actions builds a push to your project (not a pull request), any files matching target/*.{war,jar,zip} will be uploaded to your GCP bucket with the prefix builds/$DEPLOY_BUCKET_PREFIX/deploy/$BRANCH/$BUILD_NUMBER/. Pull requests will upload the same files with a prefix of builds/$DEPLOY_BUCKET_PREFIX/pull-request/$PULL_REQUEST_NUMBER/.

For example, the 36th push to the master branch will result in the following files being created in your exampleco-ops bucket:

builds/exampleco/deploy/master/36/exampleco-1.0-SNAPSHOT.war
builds/exampleco/deploy/master/36/exampleco-1.0-SNAPSHOT.zip

When the 15th pull request is created, the following files will be uploaded into your bucket:

builds/exampleco/pull-request/15/exampleco-1.0-SNAPSHOT.war
builds/exampleco/pull-request/15/exampleco-1.0-SNAPSHOT.zip

Usage

Your .github/workflows/gradle.yml should look something like this:

# This workflow will build a Java project with Gradle
# For more information see: https://help.github.com/actions/language-and-framework-guides/building-and-testing-java-with-gradle

name: Java CI with Gradle

Generate a GCP Service account

Encrypt with openssl des3 with a strong password and save to your project in /.github/deploy/gcp-deploy.json.des3 Ex : openssl des3 -in credentials.json -out gcp-deploy.json.des3 -md sha512

In Github Actions set DEPLOY_BUCKET and GCP_CREDENTIALS environmental variables GCP_CREDENTIALS is the encryption password for the GCP Service Account credentials
