1.所有节点安装docker、kubelet、kubeadm、kubectl
curl -fsSL https://get.docker.com | bash -s docker –mirror Aliyun
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-get update
apt-get install -y kubelet kubeadm kubectl
2.在master和node节点拉取海外docker镜像
kubeadm config images list列出所需要img：
k8s.gcr.io/kube-apiserver:v1.14.0
k8s.gcr.io/kube-controller-manager:v1.14.0
k8s.gcr.io/kube-scheduler:v1.14.0
k8s.gcr.io/kube-proxy:v1.14.0
k8s.gcr.io/pause:3.1
k8s.gcr.io/etcd:3.3.10
k8s.gcr.io/coredns:1.3.1
3.master上初始化
kubeadm init
初始化成功后你会看见如下提示
Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
You should now deploy a pod network to the cluster.
Run “kubectl apply -f [podnetwork].yaml” with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.0.20:6443 –token 8sio7q.g6cj9m15c0ev3d9b \
–discovery-token-ca-cert-hash sha256:81fc89c762536cadc9580278bd12fe14933ead5d9bdf5b5b1a9c07f0a3084958
4.node加入集群
kubeadm join 192.168.0.20:6443 –token 8sio7q.g6cj9m15c0ev3d9b \
–discovery-token-ca-cert-hash sha256:81fc89c762536cadc9580278bd12fe14933ead5d9bdf5b5b1a9c07f0a3084958
即可
5.coredns可能运行有问题，是因为网络还不是覆盖网络
需要安装
https://docs.projectcalico.org/v3.6/getting-started/kubernetes/installation/hosted/kubernetes-datastore/calico-networking/1.7/calico.yaml
修改里面cidr方面的参数然后创建应用 @master上
6.安装完成
