practice trigger project build on jenkins with github

• github → jenkins
  • Flow : commit code to github → jenkins build → return build result to github
  • Git project : https://github.com/alexho0205/practice_jenkins_build
  • Steps
    1. create personal token on github ( settings → developer settings )
    2. add github server on jenkins ( system → github servers )
       1. put personal token to credential ( credential type = secret text )
    3. create ssh-key pair
    4. put public key on github ( profile → settings → ssh and GPG keys → add ssh keys )
    5. put private key on jenkins ( credentials → add credentials → ssh with private key )
    6. add webhook on github (
       1. url → ${jenkins_url}/github-webhoook/
       2. content type → json
    7. create free-style job (jenkins)
    8. trigger jenkins to build project : commit code directly (github)
    9. check build result on github : repo -> commits -> green check (綠色小勾勾）
  • Bug Fix
    • 如果 jenkins 是全新的，第一次連線 github.com 前，需要加入 host key

      • ( linux )ssh 登入到 jenkins ，切換身份到 jenkins

        # 切換身份
        $ sudo su jenkins
        # 連線github.com，請自行變更 repo 位置
        # 連線後，linux 發現沒有 github.com 的 host key
        # 尋問是否加入 -> YES
        $ git ls-remote -h -- [email protected]:alexho0205/practice_jenkins_build.git HEAD

    • jenkins 需要外部IP，可使用ngrok
