Workflowsにデプロイしてみた【GCP】

まずyamlファイルを用意します。

hello.yaml

main:
  steps:
    - step1:
        call: http.post
        args:
          url: "https://asia-northeast1-run.googleapis.com/apis/run.googleapis.com/v1/namespaces/myProject/jobs/hellos:run"
          auth:
            type: OAuth2
          body:
            overrides:
              containerOverrides:
                - name: main-container
                  args:
                    - npm
                    - run
                    - helloA
        result: runHelloA
    - checkRunHelloAStatus:
        switch:
          - condition: ${runHelloA.code == 200}
            next: step2
          - condition: ${runHelloA.code != 200}
            next: logFailure
    - logFailure:
        call: sys.log
        args:
          text: ${runHelloA.code}
    - step2:
        call: http.post
        args:
          url: "https://asia-northeast1-run.googleapis.com/apis/run.googleapis.com/v1/namespaces/myProject/jobs/hellos:run"
          auth:
            type: OAuth2
          body:
            overrides:
              containerOverrides:
                - name: main-container
                  args:
                    - "npm"
                    - "run"
                    - "helloB"

URLの形式
https://{REGION}-run.googleapis.com/apis/run.googleapis.com/v1/namespaces/{PROJECT_ID}/jobs/{JOB_NAME}:run

ロジックは非常に簡単で、hellosをnpm run helloAで実行し、ステータスコード200が返ってくれば、helloBを実行し、そうでなければステータスコードをログに表示するだけです。

デプロイコマンド

上記のようになればデプロイ成功です！
