springboot-redis-docker-compose

工程结构

本工程是一个通过docker + compose 编译运行springboot + redis 应用的demo

.
├── webapp

docker-compose.yml

compose file定义了4个services：包括3个webapp，1个redis

version: "3"

services:
  webapp1:
    container_name: webapp-8083
    build: webapp
    ports:
      - "8083:8082"
    depends_on:
      - redis

  ...
  redis:
    container_name: redis
    image: redis:latest
    restart: always
    ports:
      - "6379:6379"

部署docker-compose

$ docker-compose up -d

运行结果

  • 查看运行的容器和端口号
% docker ps

  • webapp应用程序、redis启动后, 通过不同的端口号访问webapp :
guodong@mars springboot-parent % curl localhost:8083
the current page ipAddress is 172.24.0.3
the current page has been accessed 1 times%                                                          
guodong@mars springboot-parent % curl localhost:8084
the current page ipAddress is 172.24.0.4
the current page has been accessed 2 times%                                                          
guodong@mars springboot-parent % curl localhost:8085
the current page ipAddress is 172.24.0.5
the current page has been accessed 3 times%
  • 停止并且移除容器
