rancher 添加集群

正式环境为:k8s 1.10.13+ rancher 2.4.8

用rancher的管理账户登录rancher控制台

首先创建用户 zs，后面用户绑定到要添加的集群上的

其次点全局，出现集群列表----》点添加集群

这里集群名称任意，只要你知道，该名称要对应实际的集群是哪个就行，不一定非得是真实的集群的集群名称。

//自动产生了一些命令，这些命令行就是要在k8s集群上的master上要执行的

1、创建用户对应的zs账户
在集群的master 上执行 kubectl create clusterrolebinding cluster-admin-binding --clusterrole cluster-admin --user=zs

2、执行
在集群上再执行 kubectl apply -f https://rancher.aaa.com/v3/import/pxd86bhn4g6lzvm7579xh5fxhlzgn8bcrhpgtlg2n7dd2g6kcplqmm.yaml

###https://rancher.aaa.com/v3/import/pxd86bhn4g6lzvm7579xh5fxhlzgn8bcrhpgtlg2n7dd2g6kcplqmm.yaml 就是上面我用红线遮盖的部分

下面是具体看下执行过程
1、添加zs账户
[root@fp-web-157 nginx-ingress-controller]# kubectl create serviceaccount zs -n cc
serviceaccount "zs" created
2、绑定角色
[root@fp-web-157 nginx-ingress-controller]# kubectl create clusterrolebinding cluster-admin-binding --clusterrole cluster-admin --user=zs
clusterrolebinding.rbac.authorization.k8s.io "cluster-admin-binding" created
3、添加管理导入
[root@fp-web-157 nginx-ingress-controller]# kubectl apply -f https://rancher.aaa.com/v3/import/pxd86bhn4g6lzvm7579xh5fxhlzgn8bcrhpgtlg2n7dd2g6kcplqmm.yaml
clusterrole.rbac.authorization.k8s.io "proxy-clusterrole-kubeapiserver" created
clusterrolebinding.rbac.authorization.k8s.io "proxy-role-binding-kubernetes-master" created
namespace "cattle-system" created
serviceaccount "cattle" created
clusterrolebinding.rbac.authorization.k8s.io "cattle-admin-binding" created
secret "cattle-credentials-5a27d64" created
clusterrole.rbac.authorization.k8s.io "cattle-admin" created
deployment.apps "cattle-cluster-agent" created
daemonset.apps "cattle-node-agent" created
