如何将 docker 镜像作为 systemctl 服务运行？

我正在遵循说明这里，使用‘docker run’。

我想到了以下情况。容器启动，然后停止。我遗漏了什么？事实上，systemctl status 向我显示了日志的尾部；日志的其余部分在哪里？

[Unit]
Description=Jenkins
Requires=docker.service
After=docker.service

[Service]
Restart=always
ExecStart=/usr/bin/docker run -d -p 49001:8080 -v /var/jenkins_home:/var/jenkins_home -t jenkins
ExecStop=/usr/bin/docker stop -t 2 jenkins
#ExecStopPost=/usr/bin/docker rm -rf jenkins

[Install]
WantedBy=default.target

我设法从状态中获取了更多有用的数据。但我很困惑：我可以复制并粘贴 ExecStart 命令行并且它可以工作，但 systemctl 会报告退出状态。
