kubernetes - oc cluster up 超时等待条件

Question

我正在尝试在本地 Virtualbox centos 7.4 上设置 openshift origin。这是一个仅用于学习目的的多合一环境。我遵循了确切的文件:

https://docs.okd.io/latest/getting_started/administrators.html

方法一:在容器中运行

我安装了 docker，当我运行命令时，由于超时而失败:

我使用 minishift 遇到了这个问题，但原因似乎是一样的。您可以尝试以下步骤，它应该会有所帮助。

对我有用的解决方法:

使用 hyperv + oc 3.11 + minishift v1.34.1+c2ff9cb。
问题仅在不太好的互联网连接上。
一旦 minishift start 命令第一次失败，ssh 进入 minishift vm。运行 oc cluster down 后运行 oc cluster up(从日志中复制)。重复此向下/向上步骤，直到您的集群启动。它可能是 10-20 倍或更多或更少，具体取决于网络。
一旦集群启动，运行 minishift stop/start，然后你就准备好了。
希望这可以帮助
