Question

我试图在本地Virtualbox centos 7.4上设置openshift原点。这是一个多合一的环境，仅用于学习目的。我遵循了确切的文件：

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

方法1：在容器中运行

我安装了docker，并且在运行命令时由于超时而失败：

Answer 1

我在使用minishift时遇到了此问题，但原因似乎是相同的。您可以尝试以下步骤，对您有所帮助。

对我有用的解决方法：

使用hyperv + oc 3.11 + minishift v1.34.1 + c2ff9cb。问题仅在于互联网连接不佳。一旦minishift start命令第一次失败，请使用SSH进入minishift vm。先运行oc cluster down，然后运行oc cluster up（从日志中复制）。重复此向下/向上步骤，直到群集启动。根据网络的不同，可能是10到20次或更多或更少。集群启动后，运行minishift stop / start，然后就可以准备好了。希望这会有所帮助

Answer 2

在尝试修复所有可能的问题后，例如超时、EOF、错误、恐慌和其他随机问题（我在 oc 启动期间所有这些问题都发生了大约 300 次失败）后，我将虚拟机恢复为在安装以下内容之前的状态，并且我已经我猜以正确的方式完成了它，因为现在它可以正常工作（+我可以毫无压力地向上/向下做 oc cluster）

附注。也可以限制从 Openshift 拉取 100 个 Docker 镜像（尝试 docker run hello-world）。

`sudo apt update && sudo apt upgrade`

`sudo apt install curl`
`curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -`


`sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"`

`sudo apt update && sudo apt -y install docker-ce`

`sudo usermod -aG docker XXXX`

`groups XXXX`


`wget https://github.com/openshift/origin/releases/download/v3.11.0/openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit.tar.gz`


`cat << EOF | sudo tee /etc/docker/daemon.json
 {
    "insecure-registries" : [ "172.30.0.0/16" ]
 }
 EOF`

`sudo systemctl daemon-reload`
`sudo systemctl restart docker`

`sudo systemctl is-enabled docker`
`sudo systemctl is-active docker`
