kubeadm中怎么部署高可用Kubernetes

这期内容当中小编将会给大家带来有关kubeadm中怎么部署高可用Kubernetes，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。

创建集群：

sudo kubeadm init --kubernetes-version=v1.17.0 \--apiserver-advertise-address=192.168.199.173 \--control-plane-endpoint=192.168.199.173:6443 \--pod-network-cidr=10.244.0.0/16 \--upload-certs

注意：

• 增加--control-plane-endpoint参数，是用于多Master的部署使用，必须加上。

• 使用多个Master节点的kubeadm init方法后，输出有所不同。如下：

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/configYou 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/You can now join any number of the control-plane node running the following command on each as root:  kubeadm join 192.168.199.173:6443 --token rlxvkn.2ine1loolri50tzt \    --discovery-token-ca-cert-hash sha256:86e68de8febb844ab8f015f6af4526d78a980d9cdcf7863eebb05b17c24b9383 \    --control-plane --certificate-key 440a880086e7e9cbbcebbd7924e6a9562d77ee8de7e0ec63511436f2467f7ddePlease note that the certificate-key gives access to cluster sensitive data, keep it secret!As a safeguard, uploaded-certs will be deleted in two hours; If necessary, you can use"kubeadm init phase upload-certs --upload-certs" to reload certs afterward.Then you can join any number of worker nodes by running the following on each as root:kubeadm join 192.168.199.173:6443 --token rlxvkn.2ine1loolri50tzt \    --discovery-token-ca-cert-hash sha256:86e68de8febb844ab8f015f6af4526d78a980d9cdcf7863eebb05b17c24b9383

运行下面的命令，以使kubectl在当前用户账号下可用：

mkdir -p $HOME/.kubesudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/configsudo chown $(id -u):$(id -g) $HOME/.kube/config

• 注意：

• 上面带--control-plane参数的命令用于部署一个新的Master节点。

• 不带--control-plane参数的命令用于部署worker节点。

增加Master节点：

  kubeadm join 192.168.199.173:6443 --token rlxvkn.2ine1loolri50tzt \    --discovery-token-ca-cert-hash sha256:86e68de8febb844ab8f015f6af4526d78a980d9cdcf7863eebb05b17c24b9383 \    --control-plane --certificate-key 440a880086e7e9cbbcebbd7924e6a9562d77ee8de7e0ec63511436f2467f7dde

After Add master node:

sudo kubeadm init phase upload-certs --upload-certs### Got:# [upload-certs] Using certificate key:# 2ffe5bbf7d2e670d5bcfb03dac194e2f21eb9715f2099c5f8574e4ba7679ff78# Add certificate-key for Multi Master Node.kubeadm token create --print-join-command --certificate-key 2ffe5bbf7d2e670d5bcfb03dac194e2f21eb9715f2099c5f8574e4ba7679ff78

增加Worker节点：

kubeadm join 192.168.199.173:6443 --token rlxvkn.2ine1loolri50tzt \    --discovery-token-ca-cert-hash sha256:86e68de8febb844ab8f015f6af4526d78a980d9cdcf7863eebb05b17c24b9383

然后部署Network CNI驱动，如下：

docker pull quay.io/coreos/flannel:v0.11.0-amd64kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

查看一下节点状态：

kubectl get node -o wide
