構建命令 及啟動docker 映象

mvn package
或
mvn clean package

啟動docker 映象

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 內的埠

其他說明

自動構建docker 映象配置主要在 plugin中的com.spotify內
說明:

合併構建命令

                    <execution>
                        <id>build-image</id>
                        <phase>package</phase>
                        <goals>
                            <goal>build</goal>
                        </goals>
                    </execution>

此配置 主要是 執行 mvn package 時 自動 執行 mvn docker:build，如果沒有此配置那麼要執行

mvn pakage docker:build
或
mvn clean pakage docker:build

同時推送映象到倉庫

推送遠端倉庫

在MAVEN 的全域性配置檔案settings.xml加入或修改

<servers>
<server>
    <id>docker-hub</id>
    <username>docker Hub 的使用者名稱</username>
    <password>docker Hub 的密碼</password>
    <configuration>
        <email>docker Hub 的郵箱</email>
    </configuration>
</server>
</servers>

接著修改 pom.xml 中的 plugin的com.spotify在configuration元素內增加

<!--就是settings.xml 中 server.id -->
<serverId>docker-hub</serverId>

執行命令

mvn  clean package -DpushImage

注意：pushImage標識，標識推送映象標識，沒有此標識，則不推送

推送到本地倉庫

本地倉庫很簡單
修改 pom.xml 中的 plugin的com.spotify的configuration.imageName元素增加 本地地址和埠即可
例如：本地 倉庫地址及埠為 http://localhsot:5000
原 imageName為

<imageName>fox/fox-eureka-server</imageName>

修改為

<imageName>localhost:5000/fox/fox-eureka-server</imageName>

執行命令

mvn clean package docker:build -DpushImage

注意：pushImage標識，標識推送映象標識，沒有此標識，則不推送

docker compose 編排

修改所有微服務配置eureka.client.serviceUrl.defaultZone (fox-eureka-server除外):

eureka.client.serviceUrl.defaultZone=http://peer1:1111/eureka/,http://peer2:1112/eureka/

注意，以上修改完成後，要重新構建及推送到倉庫

docker-compose.yml 檔案如下

version : "2"
services :
    peer1:
        image:fox/fox-eureka-server:0.0.1
        ports:
            - "1111:1111"
        environment:
            - spring.profiles.active=peer1
    peer2:
        image:fox/fox-eureka-server:0.0.1
        ports:
            - "1112:1112"
        environment:
            - spring.profiles.active=peer2

    service-provider:
        image:fox/fox-eureka-service-provider:0.0.1
    feign-service--consumer:
        image:fox/fox-eureka-feign-service-consumer:0.0.1
    api-gateway:
        image:fox/api-gateway:0.0.1
    config-eureka-server:
        image:fox/config-eureka-server:0.0.1
    config-eureka-client:
        image:fox/config-eureka-client:0.0.1
    fox-dashboard:
        image:fox/fox-dashboard:0.0.1

注意，這裡只是一個 docker compose 案例，具體需要開啟哪些埠需要 自己去配置

最後執行命令

docker-compose up

開啟瀏覽器 網址 http://localhost:1111 即可看到效果
