kubectl 不输出日志

Question

我使用以下命令打印所有 Pod：

$ kubectl get pods --all-namespaces

输出是：

NAMESPACE             NAME                                                  READY   STATUS    RESTARTS   AGE

但是当我执行日志命令时：

$ kubectl logs -f install-ingress

我看到这个错误

Error from server (NotFound): pods "install-ingress" not found

Answer 1

该install-ingress吊舱是在gitlab-managed-apps命名空间。如果您没有在kubectl命令中指定命名空间，那么它将在默认命名空间中搜索install-ingress不存在 Pod 的 Pod。

您能否尝试以下命令（指定 pod 的命名空间）。

kubectl logs -f install-ingress -n gitlab-managed-apps
