docker部署本地springboot項目

官網：https://spring.io/guides/gs/spring-boot-docker/

參考文檔：https://my.oschina.net/AmosWang/blog/2088358

阿里雲docker信息:https://cr.console.aliyun.com/cn-hangzhou/instances/repositories

1.在項目的pom文件中添加：

            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>dockerfile-maven-plugin</artifactId>
                <version>1.3.6</version>
                <configuration>
                    <repository>${docker.image.prefix}/${project.artifactId} 
                    </repository>
                    <buildArgs>
                        <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
                    </buildArgs>
                </configuration>
            </plugin>



<properties>
        <java.version>1.8</java.version>
        <docker.image.prefix>pheony</docker.image.prefix>
</properties>

在項目目錄下添加Dockerfile文件

FROM openjdk:8-jdk-alpine
VOLUME /tmp
ARG JAR_FILE
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-jar","/app.jar"]

2.項目打包

idea直接右邊欄install即可或mvn install打包，生成文件在target目錄下

3.本地安裝docker 打開shell在項目目錄下運行：mvn clean package docker:build  

  錯誤：No plugin found for prefix 'docker' in the current project and in the plugin groups.

            修改 maven 的配置文件 settings.xml

<pluginGroups>
    <pluginGroup>com.spotify</pluginGroup>
</pluginGroups>

錯誤：Must specify baseImage if dockerDirectory

          使用mvn clean package dockerfile:build

 

 4.本地鏡像上傳倉庫，服務器上docker拉取

 https://cr.console.aliyun.com/repository/cn-hangzhou/sycamore/sycamore/details

參照模板，此案例命令：

本地鏡像上傳
docker login --username=darksinco registry.cn-hangzhou.aliyuncs.com

docker tag 854bcdabbe68 house

docker tag 854bcdabbe68 registry.cn-hangzhou.aliyuncs.com/sycamore/sycamore:house

docker push registry.cn-hangzhou.aliyuncs.com/sycamore/sycamore:house

服務器端拉取鏡像
docker login --username=darksinco registry.cn-hangzhou.aliyuncs.com

docker pull registry.cn-hangzhou.aliyuncs.com/sycamore/sycamore:house

5.服務器運行項目

docker run -p 8090:8090 -t registry.cn-hangzhou.aliyuncs.com/sycamore/sycamore:house
