15.3. 检查安全性上下文约束对象
您可以查看特定 SCC 的信息,包括这个 SCC 应用到哪些用户、服务帐户和组。
例如,检查 restricted SCC:
$ oc describe scc restricted Name: restricted Priority: <none> Access: Users: <none> 1 Groups: system:authenticated 2 Settings: Allow Privileged: false Default Add Capabilities: <none> Required Drop Capabilities: KILL,MKNOD,SYS_CHROOT,SETUID,SETGID Allowed Capabilities: <none> Allowed Seccomp Profiles: <none> Allowed Volume Types: configMap,downwardAPI,emptyDir,persistentVolumeClaim,projected,secret Allow Host Network: false Allow Host Ports: false Allow Host PID: false Allow Host IPC: false Read Only Root Filesystem: false Run As User Strategy: MustRunAsRange UID: <none> UID Range Min: <none> UID Range Max: <none> SELinux Context Strategy: MustRunAs User: <none> Role: <none> Type: <none> Level: <none> FSGroup Strategy: MustRunAs Ranges: <none> Supplemental Groups Strategy: RunAsAny Ranges: <none>
注意
要在升级过程中保留自定义 SCC,请不要编辑优先级、用户、组、标签和注解以外的默认 SCC 的设置。
