ubuntu2204安装minikube【踩坑版】

参考链接 https://zhuanlan.zhihu.com/p/429690423

1.安装docker

apt-get update
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
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"
apt-get install http://docker.io 
systemctl start docker
systemctl enable docker

docker version

 

配置阿里云的代理，通过修改daemon配置文件/etc/docker/daemon.json来使用加速器：

$ cd /etc/docker
# 在daemon.json文件末尾追加如下配置：
$ sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://dhx52mku.mirror.aliyuncs.com"]
}
EOF

# 重启docker
$ sudo systemctl daemon-reload
$ sudo systemctl restart docker

2.安装minikube

curl -Lo minikube https://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/releases/v1.23.1/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

root@k8s:/usr/local/bin# minikube start
* minikube v1.23.1 on Ubuntu 22.04
* Kubernetes 1.22.1 is now available. If you would like to upgrade, specify: --kubernetes-version=v1.22.1
* Using the none driver based on existing profile

X Exiting due to GUEST_MISSING_CONNTRACK: Sorry, Kubernetes 1.22.1 requires conntrack to be installed in root's path

 

报错1：Kubernetes 1.22.1 requires conntrack to be installed in root's path

参考链接 https://installati.one/install-conntrack-ubuntu-20-04/

#安装 conntrack

apt-get update
apt-get -y install conntrack
minikube start

 

报错2：X Exiting due to K8S_INSTALL_FAILED: updating control plane: downloading binaries: downloading kubelet: download failed: https://kubernetes.oss-cn-hangzhou.aliyuncs.com/kubernetes-release***

参考链接  https://github.com/kubernetes/minikube/issues/17661

#指定仓库安装
minikube start --image-mirror-country='cn' --image-repository='registry.cn-hangzhou.aliyuncs.com/google_containers' --kubernetes-version=v1.23.1

 

报错3：Unable to scale down deployment "coredns" in namespace "kube-system" to 1 replica: client: client config: invalid configuration: [unable to read client-cert /root/.minikube/profiles/minikube/client.crt for minikube due to open***

##原因如下
client.key client.crt目录不对
实际是在/root/.minikube/ 目录下，而~/.kube/config配置的是/root/.minikube/profiles/minikube/
需要修改 ~/.kube/config对应目录信息后再启动

----------------------------------------------------------------
