今天 Gitlab 上 CI 一片飄紅，所有 Android 的項(xiàng)目全部編譯失敗

FAILURE: Build failed with an exception.

* What went wrong:
Could not connect to the Gradle daemon.
Daemon uid: 
Daemon pid: 
  log file: /home/gitlab_ci_multi_runner/.gradle/daemon/2.14.1/daemon-9343.out.log

各種嘗試解決錯(cuò)誤不提

最后自己看 log 發(fā)現(xiàn)似乎跟 loop back 接口有關(guān)，ifconfig 一看果然沒(méi)有了 lo，但是有一個(gè) docker 的接口?；叵肫饋?lái)，很久以前 gitlab-runner 是通過(guò) docker 安裝的，雖然后來(lái)不用了，docker 也一直保留著了?？赡苁悄炒胃潞蟀?lo 搞沒(méi)了吧。卸載docker 重啟后正常。
