安装k8s 1.19.0和kube-ovn

参考博客—安装与重装k8s 1.15.0

针对ubuntu，安装kubelet、kubectl、kubeadm。

# 更新源
curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | apt-key add -
cat <<EOF >/etc/apt/sources.list.d/kubernetes.list
deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main
EOF
apt update
# 查看可用版本
apt-cache madison kubectl
apt install -y kubelet=1.19.0-00 kubeadm=1.19.0-00 kubectl=1.19.0-00

1. 安装k8s 1.19.0软件包

# 查看k8s版本对应的镜像
kubeadm config images list --kubernetes-version [version]

yum install -y kubelet-1.19.0 kubeadm-1.19.0 kubectl-1.19.0
images=(kube-apiserver:v1.19.0 kube-controller-manager:v1.19.0 kube-scheduler:v1.19.0
 etcd:3.4.9-1 coredns:1.7.0 pause:3.2 kube-proxy:v1.19.0)
for imageName in ${images[@]} ; do
    docker pull registry.aliyuncs.com/google_containers/$imageName
    docker tag registry.aliyuncs.com/google_containers/$imageName k8s.gcr.io/$imageName
    docker rmi registry.aliyuncs.com/google_containers/$imageName
done

2. 修改kubeadm.yaml

3. 初始化k8s集群

kubeadm init --config kubeadm.yaml

4. 安装kube-ovn

wget https://raw.githubusercontent.com/kubeovn/kube-ovn/release-1.10/dist/images/install.sh
vim install.sh

bash install.sh
