Jul*_*oro 5 kubernetes minikube
我只是将 Ubuntu 从 19.04 升级到 19.10
现在 Minikube 将无法启动。
所以，过了一会儿，我就完全删除了 Minikube with。
minikube stop; minikube delete
docker stop $(docker ps -aq)
rm -r ~/.kube ~/.minikube
sudo rm /usr/local/bin/localkube /usr/local/bin/minikube
systemctl stop '*kubelet*.mount'
sudo rm -rf /etc/kubernetes/
docker system prune -af --volumes
现在我想重新安装所有东西，但我无法让它工作。
下载minikube，移动到 /usr/local/bin
curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 \\n && chmod +x minikube && sudo mv ./minikube /usr/local/bin
我开始 minikube
sudo minikube start --vm-driver=none
一切正常，minukube 启动成功。
~ sudo minikube start --vm-driver=none
minikube v1.4.0 on Ubuntu 19.10

?? For more information, see:
https://minikube.sigs.k8s.io/docs/reference/drivers/none/
?? kubectl and minikube configuration will be stored in /root
?? To use kubectl or minikube commands as your own user, you may need to relocate them. For example, to overwrite your own settings, run:
? sudo mv /root/.kube /root/.minikube $HOME
? sudo chown -R $USER $HOME/.kube $HOME/.minikube
This can also be done automatically by setting the env var CHANGE_MINIKUBE_NONE_USER=true
? Waiting for: apiserver proxy etcd scheduler controller dns
Done! kubectl is now configured to use "minikube"
我终于做到了：
~ sudo mv /root/.kube /root/.minikube $HOME
? ~ sudo chown -R $USER $HOME/.kube $HOME/.minikube
但是当我想检查豆荚时：
kubectl get po
我得到：
? ~ kubectl get po
Error in configuration:
* unable to read client-cert /root/.minikube/client.crt for minikube due to open /root/.minikube/client.crt: permission denied
* unable to read client-key /root/.minikube/client.key for minikube due to open /root/.minikube/client.key: permission denied
* unable to read certificate-authority /root/.minikube/ca.crt for minikube due to open /root/.minikube/ca.crt: permission denied
如果使用 sudo：
~ sudo kubectl get po
[sudo] password for julien:
The connection to the server localhost:8080 was refused - did you specify the right host or port?
这是结果 minikube logs

我该怎么办 ？
编辑：
重新启动后，使用以下命令启动 minikube 时：
sudo minikube start --vm-driver=none
我得到：

Sorry that minikube crashed. If this was unexpected, we would love to hear from you:

好的，所以我在将 minikube 升级到 19.10 后复制并遇到了相同的错误。
我如何在 19.04 上启动集群：
#Install kubectl
curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl && chmod +x ./kubectl && sudo mv ./kubectl /usr/local/bin/kubectl
#Install minikube. Make sure to check for latest version
curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/
#Install Docker
curl -fsSL get.docker.com -o get-docker.sh && chmod +x get-docker.sh
sh get-docker.sh
sudo usermod -aG docker $USER
export MINIKUBE_WANTUPDATENOTIFICATION=false

export CHANGE_MINIKUBE_NONE_USER=true
export KUBECONFIG=$HOME/.kube/config
sudo minikube start --vm-driver none
sudo chown -R $USER $HOME/.kube $HOME/.minikube

升级到 19.10 并清洁 minikube 安装后：
vkr@ubuntu-minikube:~$ kubectl get all -A

有很多讨论表明您应该使用rootfornone driver因为 minikube 直接在您的机器上运行 kubernetes 系统组件......
https://minikube.sigs.k8s.io/docs/reference/drivers/none/：
用法 none 驱动程序要求 minikube 以 root 身份运行，直到 可以解决#3760
然而..这里有一个小技巧给你..
1）擦拭一切
vkr@ubuntu-minikube:~$ minikube stop
? Stopping "minikube" in none ...
"minikube" stopped.
vkr@ubuntu-minikube:~$ minikube delete
Uninstalling Kubernetes v1.16.0 using kubeadm ...
Deleting "minikube" in none ...
The "minikube" cluster has been deleted.
vkr@ubuntu-minikube:~$ rm -rf ~/.kube
vkr@ubuntu-minikube:~$ rm -rf ~/.minikube
vkr@ubuntu-minikube:~$ sudo rm -rf /var/lib/minikube
vkr@ubuntu-minikube:~$ sudo rm -rf /etc/kubernetes
vkr@ubuntu-minikube:~$ sudo rm -rf /root/.minikube
vkr@ubuntu-minikube:~$ sudo rm -rf /usr/local/bin/minikube
2）安装minikube，导出变量，勾选
vkr@ubuntu-minikube:~$ curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/
vkr@ubuntu-minikube:~$ export MINIKUBE_WANTUPDATENOTIFICATION=false
vkr@ubuntu-minikube:~$ export MINIKUBE_WANTREPORTERRORPROMPT=false
vkr@ubuntu-minikube:~$ export MINIKUBE_HOME=$HOME
vkr@ubuntu-minikube:~$ export CHANGE_MINIKUBE_NONE_USER=true
vkr@ubuntu-minikube:~$ export KUBECONFIG=$HOME/.kube/config
vkr@ubuntu-minikube:~$ sudo minikube start --vm-driver none

?? The 'none' driver provides limited isolation and may reduce system security and reliability.
?? For more information, see:
https://minikube.sigs.k8s.io/docs/reference/drivers/none/
?? kubectl and minikube configuration will be stored in /root
?? To use kubectl or minikube commands as your own user, you may need to relocate them. For example, to overwrite your own settings, run:

This can also be done automatically by setting the env var CHANGE_MINIKUBE_NONE_USER=true
? Waiting for: apiserver proxy etcd scheduler controller dns
Done! kubectl is now configured to use "minikube"
我下一步做的就是复制一切从/root/.kube和/root/.minikube到$HOME，授予用户权限，最后编辑$HOME/.kube/config指定新路径证书（$HOME/.minikube/而不是/root/.minikube/）。现在看起来像
vkr@ubuntu-minikube:~$ cat $KUBECONFIG
apiVersion: v1
...
certificate-authority: /root/.minikube/ca.crt
...
client-certificate: /root/.minikube/client.crt
client-key: /root/.minikube/client.key
我们开始做吧 ：）
vkr@ubuntu-minikube:~$ sudo cp -r /root/.kube /root/.minikube $HOME
vkr@ubuntu-minikube:~$ sudo chown -R $USER $HOME/.kube
vkr@ubuntu-minikube:~$ sudo chown -R $USER $HOME/.minikube
sed 's/root/home\/vkr/g' $KUBECONFIG > tmp; mv tmp $KUBECONFIG
最后结果..
vkr@ubuntu-minikube:~$ kubectl get all -A
