kubernetes-operator is a control plane and manage all kubernetes cluster lifecycle.

kubernetes-operator contains several large parts：

• kubernetes-proxy: is a proxy and all requests pass through，look like a gateway.
• kube-operator: is a kubernetes operator deploy in meta kubernetes and manage all kubernetes clusters(create、scale、delete).
• cluster deploy: At present, the main focus is on kube-on-kube,and use ansible deploy kubernetes cluster and multiple kubernetes cluster applications, eg: metric-server、 promethus、log-polit、helm...
• node-operator: Manage cluster upgrade, fault self-healing, etc.

The kubernetes-operator goal：

• kube-on-kube：Similar to Ant Financial kube-on-kube-operator.
• kube-to-kube：The difference with kube-on-kube is that the master component of the business cluster is not in the meta cluster.
• kube-to-cloud-kube : Manage clusters on multiple cloud environments.

First you need to make two images，one is kubernetes-operator，the other one is ansibleinit。And deploy kubernetes-operator in your kubernetes-cluster，if you don't have a kubernetes cluster，please see scripts/REAEME.md and deploy one.

$ make images

// update your image address and deploy kubernetes-operator
$ kubectl create -f  deploy/
namespace/ecs-system created
customresourcedefinition.apiextensions.k8s.io/kubernetesclusters.ecs.yun.com created
deployment.apps/kubernetes-operator created
clusterrole.rbac.authorization.k8s.io/kubernetes-operator created
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-operator created
serviceaccount/kubernetes-operator created


// CustomResources is KubernetesCluster,"ecs" for short in the kubernetes-operator
$ kubectl get crd

// update operator server in create_ecs.sh and create a cluster
$ bash test/create_ecs.sh  

$ kubectl get ecs

1. support deploy k3s、kubeedge cluster
2. support use kops deploy cluster
3. support for multiple version deploy
4. development node-operator
5. support admission control
