HelloWorld

编写docker-compose

• docker-compose.yml

# 当前docker-compose版本

version: '3'

# 定义微服务
services:
server1:
container_name: server1
# 镜像名
image: server1:latest
# 镜像启动过程中需要的命令
command:
- "--msg=123456"
# 设置server1所依赖的镜像
links:
- server2:host2
ports:
- 8080:8081

server2:
container_name: server2
image: server2:latest
# 设置server2所依赖的镜像
links:
- server3:host3

server3:
container_name: server3
image: server3:latest

启动

• 执行

docker-compose up -d

docker-compose

停止

docker-compose down

示例项目

在Gitee上编写了一个项目，实现了以下功能

1、Dockerfile

2、docker-compose.yml

3、docker-compose传递参数给Dockerfile

4、Feign、Eureka跨主机调用

https://gitee.com/dingyi_zhidianfan/yd/tree/V0.0.1
reg-center是注册中心

yiding内是一个生产者和消费者项目，用于演示Feign的服务调用
