ubuntu18.04使用kubeadm安装k8s

1. 概述

使用kubeadm安装单master的k8s。其中最主要的是k8s的版本和镜像的获取。

2. 安装kubeadm

kubenetes阿里云镜像

sudo apt-get update && sudo apt-get install -y apt-transport-https curl
curl -s http://mirrors.aliyun.com/kubernetes/apt/doc//apt-key.gpg | sudo apt-key add -
cat <<EOF >/etc/apt/sources.list.d/kubernetes.list
deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main
EOF
sudo apt-get update
sudo apt-get install -y kubelet=1.10.1-00 kubeadm=1.10.1-00 kubectl=1.10.1-00
sudo apt-mark hold kubelet kubeadm kubectl

3. 事前准备

禁用交换分区

sudo swapoff -a

4. 将节点加入master

kubeadm token create

openssl x509 -pubkey -in /etc/kubernetes/pki/ca.crt | openssl rsa -pubin -outform der 2>/dev/null | \
   openssl dgst -sha256 -hex | sed 's/^.* //'

例：<master-ip>:<master-port>：192.168.1.192:6443

kubeadm join --token <token> <master-ip>:<master-port> --discovery-token-ca-cert-hash sha256:<hash>
