kind: MasterConfiguration

api:

  image: registry.cn-hangzhou.aliyuncs.com/google_containers/etcd-amd64:3.1.11

kubernetesVersion: v1.10.3

imageRepository: registry.cn-hangzhou.aliyuncs.com/google_containers

执行操作命令

Kubeadm  init —config /root/kubeadm.conf


2.安装kube-flannel

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/v0.10.0/Documentation/kube-flannel.yml

三.配置worker节点

1.将worker节点加入master 


kubeadm join 192.168.0.98:6443 --token catsr2.vxxxx  --discovery-token-ca-cert-hash sha256:xxxxxx    

这些信息来自master节点执行kubeadm init 完成后输出的结果


如果没有记录，可以在master节点中执行如下命令获取

kubeadm token create --print-join-command


2.安装kube-flannel

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/v0.10.0/Documentation/kube-flannel.yml

三.配置worker节点

1.将worker节点加入master 

kubeadm join 192.168.0.98:6443 --token catsr2.vxxxx  --discovery-token-ca-cert-hash sha256:xxxxxx    

这些信息来自master节点执行kubeadm init 完成后输出的结果


如果没有记录，可以在master节点中执行如下命令获取

kubeadm token create --print-join-command

2.master向worker 分发kube-proxy和flannel pod 直接去拉取 k8s.gcr.io上的镜像是不成功的

所以需要在worker节点上 先下载阿里云的镜像源中pause-amd，然后再做个tag 

docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/pause-amd64:3.1

docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/pause-amd64:3.1   k8s.gcr.io/google_containers/pause-amd64:3.1

四.Troubleshooting

1.无法执行kubectl操作，可以按照执行如下命令之一

export KUBECONFIG=/etc/kubernetes/kubelet.conf

alias kubectl='kubectl --kubeconfig=/etc/kubernetes/kubelet.conf

阿里云容器服务可以直接通过web方式一键安装，更省心省力
