Deployment Tips

K8s 查询 Deployment 的错误

有时 Deployment 部署失败，我们通过 k descript deploy xxx 只能看到一个错误信息

Conditions:
  Type             Status  Reason
  ----             ------  ------
  ReplicaFailure   True    FailedCreate
Events:            <none>

此时我们需要找到 deploy 对应的 replicaset, describe replicaset 就能够看到对应的错误了

$ k describe replicaset <replica-set-name>

Type     Reason            Age                From                   Message
  ----     ------            ----               ----                   -------
