Docker如何一次查看多个容器日志

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

services:h2-lock:image:registry.cn-shanghai.aliyuncs.com/00fly/database-lock:1.0.0deploy:resources:limits:cpus:'2.0'memory:200Mreservations:cpus:'2.0'memory:200Menvironment:SPRING_PROFILES_ACTIVE:prodSPRING_DATASOURCE_URL:jdbc:h2:tcp://h2-server/mem:test;database_to_upper=falseSPRING_DATASOURCE_DRIVERCLASSNAME:org.h2.DriverSPRING_DATASOURCE_USERNAME:saSPRING_DATASOURCE_PASSWORD:restart:on-failurelogging:driver:json-fileoptions:max-size:5mmax-file:'1'h2-server:image:registry.cn-shanghai.aliyuncs.com/00fly/h2:1.4.200deploy:resources:limits:cpus:'2.0'memory:64Mreservations:cpus:'2.0'memory:64Mrestart:on-failurelogging:driver:json-fileoptions:max-size:5mmax-file:'1'

2, 水平扩容脚本

scale-lock.sh

#!/bin/bashdockercompose--compatibilityup-d--scaleh2-lock=3

3, 运行效果

执行以下脚本，启动服务

shscale-lock.shdockerps

输出如下

[root@00fly scale]# sh scale-lock.sh[+]Running5/5 ✔ Network scale_default Created0.2s ✔ Container scale_h2-lock_3 Started2.1s ✔ Container scale_h2-server_1 Started0.7s ✔ Container scale_h2-lock_1 Started1.4s ✔ Container scale_h2-lock_2 Started0.8s[root@00fly scale]# docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 8b4dd9e1f3d3 registry.cn-shanghai.aliyuncs.com/00fly/database-lock:1.0.0"java -Djava.securit…"13seconds ago Up12seconds scale_h2-lock_2 9459a57b39e2 registry.cn-shanghai.aliyuncs.com/00fly/h2:1.4.200"java -Djava.securit…"13seconds ago Up12seconds scale_h2-server_1 02f443bd0785 registry.cn-shanghai.aliyuncs.com/00fly/database-lock:1.0.0"java -Djava.securit…"13seconds ago Up11seconds scale_h2-lock_1 6e156442843a registry.cn-shanghai.aliyuncs.com/00fly/database-lock:1.0.0"java -Djava.securit…"13seconds ago Up10seconds scale_h2-lock_3

4, 查看多个容器日志

docker compose logs -f <服务名>

dockercompose logs-fh2-lock

输出如下
