一，简要概述
docker本身并不提供查看多个容器日志的方法，但是我们却可以利用docker scale 命令，对服务作水平扩容，这样多个服务使用的是同一的服务名。从而借助docker-compose logs 命令来查看这批服务的日志。
二，操作步骤
在安装了docker和docker-compose的lunix服务器上，创建编排文件和扩容脚本。
1, 编排文件
docker-compose.yml
yaml
services:
database-lock:
image: registry.cn-shanghai.aliyuncs.com/00fly/database-lock:1.0.0
deploy:

deploy:
resources:
limits:

reservations:
cpus: '2.0'
memory: 64M

options:

max-file: '1'2, 水平扩容脚本
bash
#!/bin/bash
docker-compose --compatibility up -d --scale database-lock=33, 运行效果
执行以下脚本，启动服务
bash
sh scale-lock.sh
docker ps输出如下
bash
[root@00fly scale]# sh scale-lock.sh

docker compose logs -f <服务名>
bash
docker compose logs -f database-lock输出如下
