Spring Boot教程第24篇:整合docker
在idea中使用docker插件,使用远程docker服务器打包。
- 在远程机器,linux上安装docker并开启docker远程访问。

这一句为添加的内容。
- pom中加入docker插件
<properties>
<docker.image.prefix>springio</docker.image.prefix>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<!--加入maven插件“docker-maven-plugin”-->
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>1.0.0</version>
<executions>
<!--执行 mvn package 时 自动 执行 mvn docker:build-->
<execution>
<id>build-image</id>
<phase>package</phase>
<goals>
<goal>build</goal>
</goals>
</execution>
</executions>
<configuration>
<imageName>${docker.image.prefix}/${project.artifactId}</imageName>
<dockerHost> http://192.168.126.138:2375</dockerHost>
<dockerDirectory>src/main/docker</dockerDirectory>
<resources>
<resource>
<targetPath>/</targetPath>
<directory>${project.build.directory}</directory>
<include>${project.build.finalName}.jar</include>
</resource>
</resources>
</configuration>
</plugin>
</plugins>
</build>
- 建立src/main/docker/Dockerfile文件
FROM frolvlad/alpine-oraclejdk8:slim
VOLUME /tmp
ADD learndocker-1.0-SNAPSHOT.jar app.jar
RUN sh -c 'touch /app.jar'
ENV JAVA_OPTS=""
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]
- 在maven插件里面有个,打包,即可
打包完的会在远程docker打包服务器中存放。
