红帽全球峰会19.2. 带有 runlabels 的容器镜像
有些红帽镜像包括为使用这些镜像提供预设置命令行的标签。使用 podman container runlabel <label> 命令，您可以使用 podman 命令执行 <label> 中为镜像定义的命令。
现有 runlabels 包括：
- install：在执行镜像前设置主机系统。通常情况下，这会在主机上创建文件和目录，容器可在稍后运行时访问。
- run：标识在运行容器时要使用的 podman 命令行选项。通常，这些选项将在主机上放开特权，并挂载容器需要永久保留在主机上的主机内容。
- uninstall ：在运行完容器后清除主机系统。
