6.7.2. 为镜像流添加标签

您可以向镜像流添加其他标签。

流程

  • 使用 `oc tag` 命令添加指向其中一个现有标签的标签:

    $ oc tag <image-name:tag1> <image-name:tag2>

    例如:

    $ oc tag python:3.5 python:latest

    输出示例

    Tag python:latest set to python@sha256:49c18358df82f4577386404991c51a9559f243e0b1bdc366df25.

  • 确认镜像流有两个标签,3.5 指向外部容器镜像,latest 指向同一镜像,因为它基于第一个标签创建而成。

    $ oc describe is/python

    输出示例
