10.4.2. 列出参数

模板的 parameter 部分列出了可覆盖的参数列表。

流程

  1. 您可使用以下命令并指定要用的文件通过 CLI 列出参数:

    $ oc process --parameters -f <filename>

    或者,如果模板已上传:

    $ oc process --parameters -n <project> <template_name>

    例如,下面显示了在默认 openshift 项目中列出其中一个快速启动模板的参数时的输出:

    $ oc process --parameters -n openshift rails-postgresql-example
