GitHub Actions

There is a demo workflow in this repository that will build, test, and deploy the app to cloud.gov when a pull request is created or changes are pushed to main. The worflow uses the cg-cli-tools action. In order to use this action you will need to create a service account in cloud.gov and store the username and password as secrets in GitHub. You can use the following command to create the service account:

$ cf create-service cloud-gov-service-account space-deployer my-service-account

Once you've created the service account you can bind a service key to it and obtain the credentials.

$ cf create-service-key my-service-account my-service-key
$ cf service-key my-service-account my-service-key
