（途中で断念）AWS ECS Workshopをやってみる（copilot編）

教材

AWS ECS Workshop

必要なもの
必須
あったほうがいい
実施手順が用意されているリージョン

Cloud9を起動していくのですが手順が用意されているのは以下のリージョンでした。

実際にやってみた

copiliot initコマンドを初めて入力

Image in a image block

最後のtest環境へのデプロイを実行した際、
Docker Imageの作成を含めて一度目は失敗したんですが、
もう一度同じコマンドを入力していくと成功しました。

  1. Application name: ecsworkshop
  2. Service Type: Load Balanced Web Service
  3. What do you want to name this Load Balanced Web Service: ecsdemo-frontend
  4. Dockerfile: ./Dockerfile
  5. Would you like to deploy a test Enviorment?: y

ログバッファが流れてしまって拾えないんですが途中で、apt-get ~ cannot foundが表示されたような...

続けます。copilot appのコマンドは以下で、

> copilot app
Commands for applications.
Applications are a collection of services and environments.

Usage
  copilot app [command]

Available Commands
  init        Creates a new empty application.
  ls          Lists all the applications in your account.
  show        Shows info about an application.
  delete      Delete all resources associated with the application.

Flags
  -h, --help   help for app

https://github.com/brentley/ecsdemo-frontend からForkして、
自身のGithubリポジトリを追加して、パイプライン追加

$ copilot pipeline update
✔ Successfully added pipeline resources to your application: ecsworkshop
Are you sure you want to update an existing pipeline: pipeline-ecsworkshop-ecsdemo-frontend? Yes
✔ Successfully updated pipeline: pipeline-ecsworkshop-ecsdemo-frontend

Recommended follow-up actions:
- Run `copilot pipeline status` to see the state of your pipeline.
- Run `copilot pipeline show` for info about your pipeline.
$

GitHubを2段階認証している人はパイプライン追加がいつまでも進まないです。
自分はハマったので別のRepositoryを新規で作成しました。
そうするとすぐにパイプライン追加処理が終わりました。。

$ git remote rm upstream
$
$ git remote add upstream <https://github.com/midnight480-shibao/ecsdemo-frontend.git>
$
$ git remote -v
origin  <https://github.com/brentley/ecsdemo-frontend> (fetch)
origin  <https://github.com/brentley/ecsdemo-frontend> (push)
upstream        <https://github.com/midnight480-shibao/ecsdemo-frontend.git> (fetch)
upstream        <https://github.com/midnight480-shibao/ecsdemo-frontend.git> (push)

CodePipelineがエラーになってしまったので、後日やり直すために記録として残します。

$ copilot pipeline delete
Are you sure you want to delete pipeline pipeline-ecsworkshop-ecsdemo-frontend from application ecsworkshop? Yes
✔ Deleted pipeline pipeline-ecsworkshop-ecsdemo-frontend from application ecsworkshop.
admin:~/environment/ecsdemo-frontend (main) $ copilot app delete
Are you sure you want to delete application ecsworkshop? Yes
✔ Deleted service ecsdemo-frontend from environment test.
✔ Deleted resources of service ecsdemo-frontend from application ecsworkshop.
✔ Deleted service ecsdemo-frontend from application ecsworkshop.
✔ Deleted environment test from application ecsworkshop.
✔ Cleaned up deployment resources.
✔ Deleted pipeline pipeline-ecsworkshop-ecsdemo-frontend from application ecsworkshop.
✔ Deleted application resources.
✔ Deleted application configuration.
✔ Deleted local .workspace file.

この記事のまとめ

途中でエラーが出るなど、うまく行かないケースがあり、
CodePipelineのエラーもCodeStarとの連携不備だったりするので、
後日別リージョンでやってみることにします。
