**以上都正常，考虑换源**

### 配置镜像源
#### 编辑Docker的配置文件
进入daemon.json文件
```bash
vim /etc/docker/daemon.json
```
#### 加入以下配置
```json
{
  "registry-mirrors" : [
	"https://docker.registry.cyou",
	"https://docker-cf.registry.cyou",
	"https://dockercf.jsdelivr.fyi",
	"https://docker.jsdelivr.fyi",

  "insecure-registries" : [
	"registry.docker-cn.com",
	"docker.mirrors.ustc.edu.cn"
  ],
  "debug": true,
  "experimental": false
}
```

重载生效
```bash
sudo systemctl daemon-reload
```

重启服务
```bash
sudo systemctl restart docker
```

重新执行：`docker compose up -d`
能够正常拉取说明问题已解决
