gcloud container clusters get-credentials 随机失败

我使用 Jenkins 运行官方掌舵图，在 GKE 上生成 kubernetes pod，我的 中有以下部分Jenkinsfile：

...
withCredentials([file(credentialsId: "${project}", variable: 'key')]) {
withEnv(["GOOGLE_APPLICATION_CREDENTIALS=${key}"]) {
  sh("gcloud --verbosity=debug auth activate-service-account --key-file ${key} --project=${project_id}")
  sh("gcloud --verbosity=debug container clusters get-credentials ${project} --zone europe-west1-b")
...

这是随机失败的，以下是没有什么帮助的输出：

你知道这是从何而来的吗？

如何进一步调试此随机故障？

最后，循环 5 次，是否可以确保避免任何网络故障？

看起来我做的很好： https://github.com/NYTimes/drone-gke/blob/f23a63fd8269182c4ce1d86302e1affc505b6441/main.go#L145
