初始化master

export MASTER_IP=172.26.124.191
export APISERVER_NAME=apiserver.demo
export POD_SUBNET=10.100.0.1/16
echo "${MASTER_IP}    ${APISERVER_NAME}" >> /etc/hosts
curl -sSL https://kuboard.cn/install-script/v1.19.x/init_master.sh | sh -s 1.19.0

检查master是否初始化成功

# 只在 master 节点执行

# 执行如下命令，等待 3-10 分钟，直到所有的容器组处于 Running 状态
watch kubectl get pod -n kube-system -o wide

# 查看 master 节点初始化结果
kubectl get nodes -o wide

使用以下命令将其它机器添加为master节点(在其它节点上运行)

kubeadm join k8s.tgeem.cn:6443 --token prk141.9o40trf0j2ezmy78 \
    --discovery-token-ca-cert-hash sha256:3ede6e97e946508b71772048a5b0cb7d755216a84ea27685706017ff2a710689 \
    --control-plane --certificate-key 01a3a4a388b61b23bfab5acfd60e2f84e5b63d1bcefe214497af5ff843f5cd9c

使用以下命令将其它机器添加为work节点(在其它节点上运行)

kubeadm join k8s.tgeem.cn:6443 --token e3r944.dgjj9cestpxhg5ud     --discovery-token-ca-cert-hash sha256:3ede6e97e946508b71772048a5b0cb7d755216a84ea27685706017ff2a710689

初始化 worker节点

在 master 节点上执行生成加入master的参数（token时效两小时）

kubeadm token create --print-join-command

kubeadm join k8s.tgeem.cn:6443 --token e3r944.dgjj9cestpxhg5ud     --discovery-token-ca-cert-hash sha256:3ede6e97e946508b71772048a5b0cb7d755216a84ea27685706017ff2a710689

加入集群

export MASTER_IP=172.26.124.191
export APISERVER_NAME=apiserver.demo
echo "${MASTER_IP}    ${APISERVER_NAME}" >> /etc/hosts

kubeadm join k8s.tgeem.cn:6443 --token e3r944.dgjj9cestpxhg5ud     --discovery-token-ca-cert-hash sha256:3ede6e97e946508b71772048a5b0cb7d755216a84ea27685706017ff2a710689

检查初始化结果

# 只在 master 节点执行
kubectl get nodes -o wide

安装 Ingress Controller

在master节点上执行以下命令

# 只在 master 节点执行
kubectl apply -f https://kuboard.cn/install-script/v1.19.x/nginx-ingress.yaml
