Install Kubernetes which is the Orchestration System for Docker Containers

Install Kubernetes which is the Orchestration System for Docker Containers. For example, Configure Kubernetes Cluster with 1 Admon Node and 2 Container Node like follows. +---------------------+ | [ Admin Node ] | | dlp.server.world | | | +----------+----------+ | +----------------------+ | +----------------------+ | [ Node01 ] |10.0.0.51 | 10.0.0.52| [ Node02 ] | | node01.server.world +----------+----------+ node02.server.world | | | | | +----------------------+ +----------------------+

	Configure Container Node on this section.
[1]	Install and Start Docker service on All Nodes, refer to here.
[2]	Install Kubernetes and Flannel on All Nodes.

[root@node01 ~]#  yum -y install kubernetes flannel

[3]	Configure Kubernetes on all Nodes like follows.

[root@node01 ~]#  vi /etc/kubernetes/config # line 22: change to Admin Node's hostname or IP address KUBE_MASTER="--master=http:// dlp.server.world :8080" [root@node01 ~]#  vi /etc/kubernetes/kubelet # line 5: change KUBELET_ADDRESS="--address= 0.0.0.0 " # line 11: change to own hostname KUBELET_HOSTNAME="--hostname_override= node01 " # line 14: change to Admin Node's hostname or IP address KUBELET_API_SERVER="--api_servers=http:// dlp.server.world :8080" [root@node01 ~]#  vi /etc/sysconfig/flanneld # line 4: change to Admin Node's hostname or IP address FLANNEL_ETCD="http:// dlp.server.world :2379" # stop docker0 interface [root@node01 ~]#  nmcli c down docker0  Connection 'docker0' successfully deactivated  (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/1) [root@node01 ~]#  systemctl start flanneld kube-proxy kubelet  [root@node01 ~]#  systemctl enable flanneld kube-proxy kubelet  [root@node01 ~]#  systemctl restart docker

[4]	Make sure th settings. It's OK if the status of each node is Ready like follows.

[root@dlp ~]#  kubectl get nodes  NAME LABELS STATUS node01 kubernetes.io/hostname=node01 Ready node02 kubernetes.io/hostname=node02 Ready
