Tips
只在 master branch 才會執行 job。
if: github.ref == 'refs/heads/master' |
因為 push event 會發生在所有 branch，可以透過這個方式限制：只有在 master 才要 publish。

Not cache artifacts and packages: We appreciate the feedback, it’s clear to us that this is necessary. We’re working on caching packages and artifacts between workflow executions, we’ll have it by mid-November.
目前還無法在 workflows 之間快取檔案，所以每次的 build，都需要重新拉取 dependency packages。當然 docker layer 也不會快取，所以都要重頭開始 build。
No Team Level Secret: This is something that is on our backlog for a future update.
目前還不支援 Team/Organization Level Secret，所以要到每個 repository 裡面設定 Secret，相當麻煩。
