systemd配置docker-compose命令

1. 概述

docker compose能够有效的管理容器之间的依赖启动关系，如果全部服务使用systemd进行管理会很麻烦。 所以使用docker compose管理服务，使用systemd管理docker compose就能有效解决这个问题

2. 配置

edgex.service文件位置/lib/systemd/system/

WorkingDirectory是compose文件所在的位置，包括.env，否则会报错找不到文件 After=docker.servicecompose依赖docker,所以必须在docker启动之后运行 Type=oneshot因为是一次性的指令，所以只需要运行一次 RemainAfterExit=yes退出之后仍然保留状态，而不会被认为失败

[Unit]
Description=edgex docker compose services
Documentation=https://github.com/kaisawind
After=docker.service
Wants=network-online.target
Requires=docker.socket

[Service]
Type=oneshot
RemainAfterExit=yes
WorkingDirectory=/home/root/data/edgex/
ExecStart=/usr/bin/docker-compose -f /home/root/data/edgex/docker-compose.yml -p edgex up -d --remove-orphans
ExecStop=/usr/bin/docker-compose -f /home/root/data/edgex/docker-compose.yml -p edgex stop

[Install]
WantedBy=multi-user.target

systemctl status edgex输出结果
