k8s-环境搭建

搭建环境

• 虚拟机：Ubuntu 22.04
• 虚拟机配置4C/4G
• 使用minikube搭建
• 配置proxychains ；在下面wget curl等下载文件时不能正常下载时使用

参考

• https://icybersec.gitbook.io/cybersecuritynote/yun-wei-pei-zhi/kubernetes/an-zhuang-bu-shu#an-zhuang-minikube
• https://blog.csdn.net/QiVictory/article/details/119535043

开始搭建

安装docker

apt install -y docker.io

go语言环境-编译cri-dockerd的go版本要大于1.9.1

• 第一种，官方，执行./installer_linux报错的话建议第二种,

wget https://storage.googleapis.com/golang/getgo/installer_linux
chmod +x ./installer_linux
./installer_linux
source ~/.bash_profile

• 第二种

wget -c https://dl.google.com/go/go1.20.4.linux-amd64.tar.gz -O - | sudo tar -xz -C /usr/local

export PATH=$PATH:/usr/local/go/bin

• go 切换国内源

go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,direct

安装 cri-dockerd

git clone https://github.com/Mirantis/cri-dockerd.git
cd cri-dockerd
mkdir bin
go build -o bin/cri-dockerd
mkdir -p /usr/local/bin
install -o root -g root -m 0755 bin/cri-dockerd /usr/local/bin/cri-dockerd
cp -a packaging/systemd/* /etc/systemd/system
sed -i -e 's,/usr/bin/cri-dockerd,/usr/local/bin/cri-dockerd,' /etc/systemd/system/cri-docker.service
systemctl daemon-reload
systemctl enable cri-docker.service
systemctl enable --now cri-docker.socket

• build -o bin/cri-dockerd编译报错可以使用下面命令,注意go的版本

go build -o bin/cri-dockerd -mod=readonly

修改/etc/systemd/system/cri-docker.socket服务

vim /etc/systemd/system/cri-docker.socket


SocketGroup=docker
改为
SocketGroup=root

创建软连接

ln -s /usr/local/bin/cri-dockerd /usr/bin/cri-dockerd

然后重启服务服务

systemctl daemon-reload
systemctl restart cri-docker.socket

查看这两个服务是否正常

systemctl status cri-docker.service
systemctl status cri-docker.socket

安装crictl

wget https://github.com/kubernetes-sigs/cri-tools/releases/download/v1.26.0/crictl-v1.26.0-linux-amd64.tar.gz
sudo tar zxvf crictl-v1.26.0-linux-amd64.tar.gz -C /usr/local/bin
rm -f zxvf crictl-v1.26.0-linux-amd64.tar.gz
ln -s /usr/local/bin/crictl /usr/bin/crictl

安装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
kubectl version --client

• kubectl 执行报错，建议一直重新下载，我个人搭建时候下载好几次才成功

安装Minikube

apt install conntrack -y

curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64  && chmod +x minikube
sudo mkdir -p /usr/local/bin/
sudo install minikube /usr/local/bin/

查看可支持的版本

minikube config defaults kubernetes-version

启动集群

• 根据大佬命令没有成功启动

minikube  start --image-mirror-country=cn  --driver=none  --kubernetes-version=1.23.15 

• 第二种

minikube start   --force 

• 配置代理（可选）

export HTTP_PROXY=http://ip:端口
export HTTPS_PROXY=https://ip:端口
export NO_PROXY=localhost,127.0.0.1,10.96.0.0/12,192.168.59.0/24,192.168.49.0/24,192.168.39.0/24##

查看pods

kubectl get pods --all-namespaces

启动metrics

minikube addons enable metrics-server

需要同时启动以下两条命令，建议使用screen分别执行

• 启动仪表盘

minikube dashboard

• 配置对外端口

kubectl proxy  --port=8088 --address='0.0.0.0' --accept-hosts='^.*'

• 访问

http://192.168.72.129:8088/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy

搭建完成
