CircleCIでGAE/Go 1.12 へデプロイする

やりたいこと

• GitHubにPushしたタイミングでGAEにデプロイする
• CircleCIを使って実現する

circleci/gcp-cli @1.8.2 を使ってGAEへデプロイする

• Orbクイックスタートガイドの通りやる

CircleCI側の設定

• BUILD SETTINGS >> Environment Variables に環境変数を設定する必要がある

  • GOOGLE_PROJECT_ID
  • GOOGLE_COMPUTE_ZONE
  • GCLOUD_SERVICE_KEY

• ServiceKeyはJsonをそのままValueにコピーする
