OpenShift CLI能够执行应用程序的所有基本和高级配置，管理，添加和部署。
我们可以使用OC命令执行各种操作。该客户端可帮助您在任何OpenShift或Kubernetes兼容平台上开发，构建，部署和运行应用程序。它还在“ adm”子命令下包括用于管理集群的管理命令。
下表列出了基本的OC命令。

登录到您的服务器并保存登录以备后用。客户端的首次用户应运行此命令以连接到服务器，建立经过身份验证的会话，并保存与配置文件的连接。默认配置将保存到您的主目录下的“ .kube / config”下。
登录所需的信息(例如用户名和密码，会话令牌或服务器详细信息)可以通过标志提供。如果未提供，该命令将根据需要提示用户输入。
用法
oc login [URL] [options]
例
# Log in interactively
oc login

oc login localhost:8443 --certificate-authority = /path/to/cert.crt
