文章目录一简要概述二操作步骤1, 编排文件2, 水平扩容脚本3, 运行效果4, 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.ymlservices:h2-lock:image:registry.cn-shanghai.aliyuncs.com/00fly/database-lock:1.0.0deploy:resources:limits:cpus:2.0memory:200Mreservations:cpus:2.0memory:200Menvironment:SPRING_PROFILES_ACTIVE:prodSPRING_DATASOURCE_URL:jdbc:h2:tcp://h2-server/mem:test;database_to_upperfalseSPRING_DATASOURCE_DRIVERCLASSNAME:org.h2.DriverSPRING_DATASOURCE_USERNAME:saSPRING_DATASOURCE_PASSWORD:restart:on-failurelogging:driver:json-fileoptions:max-size:5mmax-file:1h2-server:image:registry.cn-shanghai.aliyuncs.com/00fly/h2:1.4.200deploy:resources:limits:cpus:2.0memory:64Mreservations:cpus:2.0memory:64Mrestart:on-failurelogging:driver:json-fileoptions:max-size:5mmax-file:12,
