启动AWS EC2服务器后，由Docker-compose自动启动

问题描述

每次我重新启动EC2服务器时，我都必须这样做： sudo systemctl start docker，然后docker-compose up -d启动我的所有容器。
我想创建一个systemd来执行此answer中的建议，以在实例开始时自动运行这两个命令。

到目前为止，我已经在docker_boot.service中创建了一个/etc/systemd/system/，内容如下：

[Unit]
Description=docker boot
After=docker.service

[Service]
Type=simple
Restart=always
RestartSec=1
User=ec2-user
ExecStart=/usr/bin/docker-compose -f docker-compose.yml up

[Install]
WantedBy=multi-user.target

我不知道我的docker_boot.service文件的内容是否正确。理想情况下，关闭实例时，我也想做docker-compose down。

然后我做了：

sudo systemctl enable docker
sudo systemctl enable docker_boot

但是当我重新启动EC2实例时，我的docker映像没有运行，该如何调试呢？
请在下面找到我的docker-compose.yml文件的内容：

解决方法

要在启动时启用docker守护程序，只需运行以下命令：

sudo systemctl enable docker

要在启动时运行docker-compose up，可以在cont-tab中添加此行。必须使用撰写文件的绝对路径。

@reboot /usr/bin/docker-compose -f /absolute-path-to-your/docker-compose.yml up
