Using docker way to package server
1. In the pom.xml file to the corresponding plug (ps: docker.image.prefix name refers to the warehouse, it is recommended to use the name dockerhub otherwise not be able to submit to push its own warehouse owenwangwen)
<properties>
<docker.image.prefix>owenwangwen</docker.image.prefix>
</properties>
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>0.4.13</version>
<configuration>
<imageName>${docker.image.prefix}/${project.artifactId}</imageName>
<dockerDirectory>src/main/docker</dockerDirectory>
<!-- docker远程服务器地址 -->
<dockerHost>http://xx.xx.xx.xx:5555</dockerHost>
<resources>
<resource>
<targetPath>/</targetPath>
<directory>${project.build.directory}</directory>
<include>${project.build.finalName}.jar</include>
</resource>
</resources>
</configuration>
</plugin>
Using docker way to package server
2. Create a new package docker each module in the src / main Next, in the new Dockerfile src / main / below docker
Dockerfile file
FROM openjdk:8-jdk-alpine
VOLUME /tmp
ADD user-center.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" ]
Note: Note that (app.jar means that the project packaged jar)
Explanation:
FROM point to container name openjdk need to create: 8-jdk-alpine (in addition to the notes, must be the first line of writing, otherwise an error)
tag did not write the default fetch latest, may be considered to be the version number
ADD (add files to the vessel, the host files, network files, folders)
VOLUME (mount point, a host of other containers)
RUN (command for modifying the mirror, commonly installed library program, and a program configuration)
ENV (set the environment variable container)
CMD (start command default container)
EntryPoint (similar to the CMD, CMD used in conjunction with)
item packaged into mirror
Sample
-
Configuring docker host address
-
docker: build mirrored host docker upload
-
docker: build process is mirrored
-
Login host View Mirror
-
docker login
-
Upload hub.docker
[root@localhost ~]# docker push owenwangwen/eureka-server
