红帽全球峰会3.5.2.7.4. 更新镜像流标签
要更新标签以反映镜像流中的另一标签：
oc tag <image-name:tag> <image-name:latest>
$ oc tag <image-name:tag> <image-name:latest>
例如，以下命令更新了 latest 标签，以反映镜像流中的 3.6 标签：
oc tag python:3.6 python:latest
$ oc tag python:3.6 python:latest输出示例
Tag python:latest set to python@sha256:438208801c4806548460b27bd1fbcb7bb188273d13871ab43f.
Tag python:latest set to python@sha256:438208801c4806548460b27bd1fbcb7bb188273d13871ab43f.
