使用国内镜像站
sudo apt-get update && sudo apt-get install -y apt-transport-https curl
sudo curl -s https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | sudo apt-key add -
sudo tee /etc/apt/sources.list.d/kubernetes.list <<-'EOF'
deb https://mirrors.aliyun.com/kubernetes/apt kubernetes-xenial main
EOF
sudo apt-get update
apt-cache madison kubeadm
查看过版本之后就可以指定版本安装
$ sudo apt-get install -y kubelet=1.14.0-00 kubeadm=1.14.0-00 kubectl=1.14.0-00
$ sudo apt-mark hold kubelet=1.14.0-00 kubeadm=1.14.0-00 kubectl=1.14.0-00
开机启动kubelet
sudo systemctl enable kubelet && sudo systemctl start kubelet
解决组件镜像无法拉取的问题
不能翻墙换个方法变通处理一下
docker pull mirrorgooglecontainers/kube-apiserver:v1.14.0
docker pull mirrorgooglecontainers/kube-controller-manager:v1.14.0
docker pull mirrorgooglecontainers/kube-scheduler:v1.14.0
docker pull mirrorgooglecontainers/kube-proxy:v1.14.0
docker pull mirrorgooglecontainers/pause:3.1
docker pull mirrorgooglecontainers/etcd:3.3.10
docker pull coredns/coredns:1.3.1
在重新给下载的打个tag
docker tag docker.io/mirrorgooglecontainers/kube-apiserver:v1.14.0 k8s.gcr.io/kube-apiserver:v1.14.0
docker tag docker.io/mirrorgooglecontainers/kube-controller-manager:v1.14.0 k8s.gcr.io/kube-controller-manager:v1.14.0
docker tag docker.io/mirrorgooglecontainers/kube-scheduler:v1.14.0 k8s.gcr.io/kube-scheduler:v1.14.0
docker tag docker.io/mirrorgooglecontainers/kube-proxy:v1.14.0 k8s.gcr.io/kube-proxy:v1.14.0
docker tag docker.io/mirrorgooglecontainers/pause:3.1 k8s.gcr.io/pause:3.1
docker tag docker.io/mirrorgooglecontainers/etcd:3.3.10 k8s.gcr.io/etcd:3.3.10
docker tag docker.io/coredns/coredns:1.3.1 k8s.gcr.io/coredns:1.3.1
node01 ode02也需要pausekube-proxyflannel镜像在相应的宿主机
初始化主节点
kubeadm init --pod-network-cidr=10.244.0.0/16
export KUBECONFIG=/etc/kubernetes/admin.conf
安装flannel网络插件
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
