Micro-service container transformation documentation

A, subject: stock of items so that items can be packaged codes unmodified mirror-image manner and any new items refer to the specification modification. Follow-up of new projects in development and testing environments are deployed using container deployment.

 

Second, the specific content: To the container of micro-services need to modify the pom.xml file and add src / main / dokcer / Dockerfile file.

Specific changes are as follows:

2.1. Pom.xml file modification

    1. Add custom attribute image repository at <properties> path

<aliyun-sdk-oss.version>3.3.0</aliyun-sdk-oss.version>
<docker.repostory>registry.cn-shenzhen.aliyuncs.com</docker.repostory>
<docker.registry.name>xxxx_microservices</docker.registry.name>

 

    2. Add package upload to the mirror disposed at the warehouse <build> </ build>

 

<!-- 使用maven 配置构建 -->
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>1.0.0</version>
<configuration>
<dockerDirectory>target/docker</dockerDirectory>
<imageName>${docker.repostory}/${docker.registry.name}/${project.artifactId}-${profileActive}</imageName>

<resources>
<resource>
<targetPath>/</targetPath>
<directory>${project.build.directory}</directory>
<include>${project.build.finalName}.jar</include>
</resource>
</resources>
<serverId>docker-aliyun</serverId> 
<registryUrl>${docker.repostory}</registryUrl> 
<pushImage>true</pushImage> 
</configuration>
</plugin>

 

 

3. Add the following arranged in <resources> </ resources>:

<!-- 使用@@站位符，输出Dockerfile至docker文件夹 -->
<resource>
<directory>src/main/docker</directory>
<filtering>true</filtering>
<includes>
<include>**/Dockerfile</include>
</includes>
<targetPath>../docker</targetPath>
</resource>

2.2. Adding Dockerfile file

 

Created under src / main directory new docker, Dockerfile new file in the directory, as follows:

ARG activenv
FROM java:8-jre
ENV arch @project.artifactId@
ENV prg @[email protected]
ENV JAVA_OPTS="-Xms512m -Xmx512m"
#ENV activenv=""
EXPOSE 8084
RUN mkdir -p /vol1/appserver/$arch
WORKDIR /vol1/appserver/$arch
#VOLUME /vol1/logs
ADD $prg .
#设置时区
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
RUN sh -c echo 'Asia/Shanghai' >/etc/timezone
#ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar"]
ENTRYPOINT [ "sh", "-c", "java -Dfile.encoding=utf-8 $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar $prg  > /dev/null 2>&1" ]
