开源容器应用自动化部署技术Kubernetes安装教程
动力节点Kubernetes安装具体步骤
所有服务器节点安装 Docker/kubeadm/kubelet/kubectl
Kubernetes 默认容器运行环境是Docker,因此首先需要安装Docker;
(1)安装 Docker
更新docker的yum源
yum install wget -y
wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
安装指定版本的docker:
yum install docker-ce-19.03.13 -y
yum install docker -y (这个安装的Docker版本偏旧) 1.13.x
配置加速器加速下载 (https://cr.console.aliyun.com/)
/etc/docker/daemon.json
{
"registry-mirrors": ["https://registry.docker-cn.com"]
}
https://gg3gwnry.mirror.aliyuncs.com
然后执行:
systemctl enable docker.service
不然会提示警告;
那么接下来需要搭建:kubeadm、kubelet、kubectl
添加k8s的阿里云YUM源
cat > /etc/yum.repos.d/kubernetes.repo << EOF
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF
到时候下载k8s的相关组件才能找到下载源;
(2)安装 kubeadm,kubelet 和 kubectl
yum install kubelet-1.19.4 kubeadm-1.19.4 kubectl-1.19.4 -y
然后执行:
systemctl enable kubelet.service
不然会提示警告;
查看有没有安装:
yum list installed | grep kubelet
yum list installed | grep kubeadm
yum list installed | grep kubectl
