Node only needs to install kubelet service, and all nodes need to install kube-proxy
Deploy kubelet
1. Binary package preparation
Copy the package from to all node.
[root@node-01 ~] # cd / usr/local/src/kubernetes/server/bin/ [root @ node-01 bin] # for n in `root 204206`; do scp kubelet 10.31.90.$n:/data/kubernetes/bin/; for n in [root @ node-01 bin] # for n in `root 201206`; do scp kube-proxy 10.31.90.$n:/data/kubernetes/bin/; done
two。 Create a role binding
[root@node-01] # kubectl create clusterrolebinding kubelet-bootstrap-- clusterrole=system:node-bootstrapper-- user=kubelet-bootstrapclusterrolebinding.rbac.authorization.k8s.io/kubelet-bootstrap created
3. Create a kubelet bootstrapping kubeconfig file
Set cluster parameters
[root@node-01] # kubectl config set-cluster kubernetes\-certificate-authority=/data/kubernetes/ssl/ca.pem\-embed-certs=true\-server= https://10.31.90.200:6443\-kubeconfig=bootstrap.kubeconfigCluster "kubernetes" set.
Set the client authentication parameters. Token should use the previous one.
[root@node-01] # kubectl config set-credentials kubelet-bootstrap\-token=cf25becebf64e3fffd7f3890a60ac16d\-kubeconfig=bootstrap.kubeconfig User "kubelet-bootstrap" set.
Set context parameters
[root@node-01] # kubectl config set-context default\-- cluster=kubernetes\-- user=kubelet-bootstrap\-- kubeconfig=bootstrap.kubeconfigContext "default" created.
Select the default context
[root@node-01 ~] # kubectl config use-context default-- kubeconfig=bootstrap.kubeconfigSwitched to context "default". # copy to 3 node nodes for n in `seq 204206`; do scp bootstrap.kubeconfig 10.31.90.
Deploy kubelet (node node)
Set CNI to support (all nodes) [root@node-01 ~] # mkdir-p / etc/cni/ net.d [root @ node-01 ~] # cat > > / etc/cni/net.d/10-default.conf RemoteAddress:Port Forward Weight ActiveConn InActConnTCP 10.1.0.1 Masq 443 Masq-> 10.31.90.201 Vist6443 100
If both kubelet and proxy services are installed, you can check the status using the following command:
[root@node-01] # kubectl get nodeNAME STATUS ROLES AGE VERSION10.31.90.204 Ready 40mv1.11.510.31.90.205 Ready 40mv1.11.510.31.90.206 Ready 40mv1.11.5
Please deploy the node-05,node-06 node on your own.
Follow-up will update all the installation documents one after another, if you think I wrote well, I hope you pay more attention to like, thank you very much!
