gcloud_source_2_app_engine.md

GCP ConsoleでCloud Source Repoに格納されているソースコードをApp Engineにデプロイする手順

Commands

gcloud source repos clone [REPO_NAME] [TARGET_DIR] --project=[PROJECT_ID]

where [REPO_NAME] is Cloud Source Repository name, [TARGET_DIR] is where to put the source code, and [PROJECT_ID] is App Engine Project ID.

Install anything required by your Rails app:

sudo apt-get install libmysqlclient-dev
bundle install

Test the Rails app locally:

bundle exec rails server --port=8080

Runtime configuration

Bellow, [DOMAIN] is your rails app domain, while [SECRET_KEY] is generated by the following command:

bundle exec rails secret

Configuration file: app.yml

runtime: ruby
env: flex
entrypoint: bundle exec rackup -p $PORT

env_variables:
  SECRET_KEY_BASE: [SECRET_KEY]
  DOMAIN_NAME=[DOMAIN]

Configuration file: .ruby-version

Precompile Rails assets before deployment:

SECRET_KEY_BASE=[SECRET_KEY] DOMAIN_NAME=[DOMAIN] RAILS_ENV=production bundle exec rails assets:precompile
gcloud app deploy --project [PROJECT_ID]

Browse your app at https://[PROJECT_ID].appspot.com.
