14.3. 使用 systemd 自动启动容器

流程

1. 重新载入 systemd 管理器配置：

   # systemctl --user daemon-reload

2. 启用服务 container.service ，并在引导时启动它：

   # systemctl --user enable container.service

3. 立即启动该服务：

   # systemctl --user start container.service

4. 检查服务的状态：

   $ systemctl --user status container.service
   ● container.service - Podman container.service

   您可以使用 systemctl is-enabled container.service 命令检查服务是否已启用。
