我已经在下面的步骤中设置了k8s集群。

为什么这些错误来自pod内部,而来自主机节点的apt更新运行良好?
似乎网络的问题是网络是否需要身份验证
。
请使用另一个网络进行检查,因为我能够从容器中运行apt更新
命令。
$ kubectl run mginx --rm -i --tty --restart=Never --image=nginx -- /bin/sh
If you don't see a command prompt, try pressing enter.

我已经在我的本地Gitlab服务器上创建了一个远程存储库,我试图推送本地内容,但它要求我提供通行证,但现在是为我的用户 我试过使用我的用户通行证和根通行证,但不起作用,通行证要求什么??
我是unix系统的新手,目前在libs更新方面遇到了问题。我真的不知道如何将库Boost更新到1.55版。 我尝试过这种方式,但加速系统版本返回1.48。 我还尝试了
本文向大家介绍PHP基于文件存储实现缓存的方法,包括了PHP基于文件存储实现缓存的方法的使用技巧和注意事项,需要的朋友参考一下 本文实例讲述了PHP基于文件存储实现缓存的方法。分享给大家供大家参考。具体如下: 在一些数据库数据记录较大,但是服务器有限的时候,可能一条MySQL查询就会好几百毫秒,一个简单的页面一般也有十几条查询,这个时候也个页面加载下来基本要好几秒了,如果并发量高的话服务器基本就瘫
我不明白为什么不更新我的对象。在另一个组件中,我通过调度更新状态。在此情况下(在下面的代码中),mapStateToProps类别中的代码正在更改(控制台日志显示另一个类别)。但组件并没有重播,虽然在组件中我使用了道具。类别。事件控制台。登录元素未运行 我认为,如果我更新状态,则根据该状态更新组件。它应该如何工作?它应该如何工作?它可能很有用,添加类别的项不是父项或子项,而是邻居 谢谢你解决问题。
