  • Bash定時任務腳本執行期間剛好與開發人員執行的CI任務產生資源競爭，造成彼此無法順利完成
    • 可能解決方式:
      • 暫時: 先錯過定時任務的執行時間，避免資源競爭
      • 比較好的方式:
        • 可在原本的.gitlab-ci.yml中加入定時任務的清理腳本
        • 也可以在定時任務的清理腳本中，加入webhook與gitlab API互動，確定哪些條件下，清理腳本必需執行
        • 或者棄用原本的Shell executor，改用docker executor，達成Clean build environment for every build的效果
