Kubernetes 查找 pod 的日志

Question

尝试安装 Elastic Stack

嗨，我已通过 gitlab 自托管 ee.13.2.2 连接到集群

我正在使用 gitlab，并且安装了 ingress、prometheus、cert manager 和 runner，但是当我尝试安装 Elastic stack 时，它不会安装。有谁知道我可以在哪里找到正确的日志来找出它无法安装的原因？

错误提示：

安装 Elastic Stack 时出现问题

Operation failed. Check pod logs for install-elastic-stack for more details.

Answer 1

请尝试再次运行。 Helm 有时会很快超时。如果始终失败，请查看 elastic-stack 命名空间内部。查看哪些 Pod 未在其中启动以及您遇到了什么错误。

Answer 2

有谁知道我可以在哪里找到正确的日志来找出它无法安装的原因？

至少，使用 GitLab 17.4（2024 年 9 月），您在查找这些日志时不会遇到任何问题：您将在 GitLab 的 Kubernetes 仪表板中看到一个“

View Logs

”按钮。

列出 Kubernetes 资源事件

GitLab 提供 pod 和流式 pod 日志的实时视图。然而，到目前为止，我们还没有从 UI 中向您显示特定于资源的事件信息，因此您仍然必须使用第 3 方工具来调试 Kubernetes 部署。
此版本将事件添加到 Kubernetes 仪表板的资源详细信息视图中。

这是我们第一次向 UI 添加事件。目前，每次打开资源详细信息视图时都会刷新事件。您可以在issue 470042中跟踪实时事件流的开发。

请参阅文档和问题。
