每次重新启动EC2服务器时，我都必须执行以下操作：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 来执行此操作，按照本答案中的建议在实例开始时自动运行这两个命令。
到目前为止，我已经在/etc/systemd/system/创建了一个包含以下内容的docker_boot.service：
[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，我也想在关闭实例时做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，我该如何调试它？
请在下面找到我的docker-compose.yml文件的内容：

- 在 EC2 计算机上运行此命令，以在启动时使用以下命令启用 docker 守护程序：
sudo systemctl enable docker
- 将
restart: always添加到您的docker-compose.yaml文件中，如下所示：
version: "3.1"
services:
my-server:
image: .../server:0.0.1
restart: always
...
要在启动时启用 docker 守护程序，只需运行以下命令：
sudo systemctl enable docker
要在引导时运行docker-compose up，您可以在 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
