Rancher CLI是一个统一的工具，可用于与Rancher进行交互。借助于此工具，我们可以使用命令行来操作Rancher并管理其下的资源。

  • 1、下载rancher-cli工具

可以通过官方的文件下载页面进行下载，也可以直接在首页右下角的下载cli进行下载，这里直接通过命令方式进行下载。

  1. [root@jenkins ~]$ wget https://releases.rancher.com/cli2/v2.2.0/rancher-linux-amd64-v2.2.0.tar.gz
  2. [root@jenkins ~]$ tar xf rancher-linux-amd64-v2.2.0.tar.gz
  • 2、配置进系统中
  1. mv rancher-v2.2.0/rancher /usr/bin/rancher
  2. rm -rf rancher-v2.2.0/
  • 3、测试登录

新建用户获取tonken：

创建一个永不过期的token，以用于验证使用。

使用如下命令进行登陆：

  1. [root@jenkins ~]$ rancher login https://rancher.com/v3 --token token-fkgj6:gd2z99wnfgc2zw9pw969rppgbnrfwg7l59l4gccqp5wmdc6vd27r5l

注意：这里测试的主机需要能够访问rancher.com，如果都在内网环境中，那么可以直接把域名对应解析写入到主机hosts中。

注意，还需要安装kubectl命令，否则执行相关操作时会报如下错误：

  1. FATA[0000] kubectl is required to be set in your path to use this command. See https://kubernetes.io/docs/tasks/tools/install-kubectl/ for more info. Error: exec: "kubectl": executable file not found in $PATH

随便执行一下命令验证一下。

  1. [root@jenkins ~]$ rancher kubectl get node
  2. NAME STATUS ROLES AGE VERSION
  3. 192.168.106.3 Ready controlplane,etcd,worker 32m v1.11.6
  4. 192.168.106.4 Ready controlplane,etcd,worker 32m v1.11.6
  5. 192.168.106.5 Ready controlplane,etcd,worker 32m v1.11.6

借此机会来个安装应用的定妆照！

  1. [root@jenkins ~]$rancher kubectl get pod --all-namespaces
  2. NAMESPACE NAME READY STATUS RESTARTSAGE

OK，看到能够这样执行命令，就可以了，后边的流水线工作就不用发愁了。
