构建命令 及启动docker 镜像
mvn package或mvn clean package
启动docker 镜像
docker run -d -p 1111:1111 fox/fox-eureka-server:0.0.1 --name fox-eureka-server:0.0.1
1111 是 fox-eureka-server 内的端口
其他说明
自动构建docker 镜像配置主要在plugin中的com.spotify内
说明:
合并构建命令
<execution><id>build-image</id><phase>package</phase><goals><goal>build</goal></goals></execution>
此配置 主要是 执行mvn package时 自动 执行mvn docker:build，如果没有此配置那么要执行
mvn pakage docker:build或mvn clean pakage docker:build
同时推送镜像到仓库
推送远程仓库
在MAVEN 的全局配置文件settings.xml加入或修改
<servers><server><id>docker-hub</id><username>docker Hub 的用户名</username><password>docker Hub 的密码</password><configuration><email>docker Hub 的邮箱</email></configuration></server></servers>
接着修改pom.xml中的plugin的com.spotify在configuration元素内增加
<!--就是settings.xml 中 server.id --><serverId>docker-hub</serverId>
执行命令
mvn clean package -DpushImage
注意：pushImage标识，标识推送镜像标识，没有此标识，则不推送
推送到本地仓库
本地仓库很简单
修改pom.xml中的plugin的com.spotify的configuration.imageName元素增加 本地地址和端口即可
例如：本地 仓库地址及端口为http://localhsot:5000
原imageName为
<imageName>fox/fox-eureka-server</imageName>
修改为
<imageName>localhost:5000/fox/fox-eureka-server</imageName>
执行命令
mvn clean package docker:build -DpushImage
注意：pushImage标识，标识推送镜像标识，没有此标识，则不推送

docker compose 编排
修改所有微服务配置eureka.client.serviceUrl.defaultZone(fox-eureka-server除外):
eureka.client.serviceUrl.defaultZone=http://peer1:1111/eureka/,http://peer2:1112/eureka/
注意，以上修改完成后，要重新构建及推送到仓库
docker-compose.yml文件如下
version : "2"services :peer1:image:fox/fox-eureka-server:0.0.1ports:- "1111:1111"environment:- spring.profiles.active=peer1peer2:image:fox/fox-eureka-server:0.0.1ports:- "1112:1112"environment:- spring.profiles.active=peer2service-provider:image:fox/fox-eureka-service-provider:0.0.1feign-service--consumer:image:fox/fox-eureka-feign-service-consumer:0.0.1api-gateway:image:fox/api-gateway:0.0.1config-eureka-server:image:fox/config-eureka-server:0.0.1config-eureka-client:image:fox/config-eureka-client:0.0.1fox-dashboard:image:fox/fox-dashboard:0.0.1
注意，这里只是一个 docker compose 案例，具体需要开启哪些端口需要 自己去配置
最后执行命令
docker-compose up
打开浏览器 网址http://localhost:1111即可看到效果
