Rancher执行kubectl命令

Rancher部署成功后执行kubectl命令只能在控制台执行，无法在宿主机直接执行很不方便。

配置步骤：

1.在宿主机上下载kubectl 二进制文件

[root@devops-k8s19-38 ~]# curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 45.3M 100 45.3M 0 0 2803k 0 0:00:16 0:00:16 --:--:-- 2809k

[root@devops-k8s19-38 ~]# chmod +x ./kubectl
[root@devops-k8s19-38 ~]# sudo mv ./kubectl /usr/local/bin/kubectl

如果服务器上下载不了kubectl可去github release页面下载最新版kubectl，再上传至服务器

2.复制集群的kubeconfig文件

进入集群仪表盘，选中集群进入，复制kubeconfig文件中全部内容

 

 3.在安装好kubectl的机器上配置kubeconfig ，将复制的文件内容全部保存在config文件中

[root@devops-k8s19-38 ~]# mkdir ~/.kube
[root@devops-k8s19-38 ~]# vim ~/.kube/config

4. 测试是否可以执行kubectl 命令

[root@devops-k8s19-38 ~]# kubectl get ns
NAME STATUS AGE
cattle-system Active 24h
default Active 24h
fleet-system Active 24h
ingress-nginx Active 24h
kube-node-lease Active 24h
kube-public Active 24h
kube-system Active 24h
security-scan Active 24h
[root@devops-k8s19-38 ~]#
[root@devops-k8s19-38 ~]#
[root@devops-k8s19-38 ~]# kubectl get nodes
