Build pipeline for development / testing / production.

[casek]

• create frontend app by quasar-cli
• create backend app by Flask
• build Docker container for PostgreSQL / mailhog / frontend app / backend app.
• build test env.
  • frontend
  • install cypress AE
  • signup Cypress Cloud (https://cloud.cypress.io/projects/bq461j)
  • run e2e test
  • backend
  • install pytest
  • (change directory layout)
  • create dummy test
  • run unit test

[casek]

• github actions向けにself hosted runnerを用意
• frontendのdocker containerを少々調整
  • Cypressのrecord keyを環境変数から取得するように変更（←最初はpackage.jsonにハードコードしていた...）
  • docker hubのnode imageを最新（21-bullseye）に変更したが…yarnがnode21は対応してない（新しすぎ）と言って怒るのでlts-bullseye(node 20)に戻す

[casek]

• create workflows for github actions.
  • write workflow for frontend and backend
  • set actions variable CYPRESS_KEY (cypress record key) on github repo.
  • using self-host by ec2 instance on wazzup aws account.
  • for Amazon Linux 2023... (not need this for ubuntu-latest)
    • make symbolic link... python3 -> python
    • yum install python(version)-pip
    • make symbolic link... pip(version) -> pip
    • must be the same version between python and pip. (Amazon Linux 2023 I use has python 3.9...)
    • the following is required for cypress
    • yum install -y Xvfb
    • yum install -y pango pango pango-devel libXrandr libXrandr-devel libXcursor libXcursor-devel cups-libs
    • yum install atk atk-devel
    • yum -y install at-spi2-atk.x86_64 for "atk-bridge"
    • yum install gtk3 gtk3-devel
    • yum install alsa-lib for "libasound"

  • It may be better to build self-hosted runner with ubuntu...
• create branch protection rule
  • to disallow force push to main branch...
  • on "Require a pull request before merging"
    • on "Dismiss stale pull request approvals when new commits are pushed"
  • on "Do not allow bypassing the above settings"
  • but... disable this rule for the time being.

[casek]

• change workflows
  • merge frontend workflow and backend workflow using tj-actions/changed-files@v42
• available branch protection rule for "main"
