This article mainly introduces how to use docker-maven-plugin automation deployment, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

1. Docker-maven-plugin introduction

In the process of continuous integration, project projects are generally compiled and packaged with Maven, and then generate an image, which can greatly provide online efficiency, rapid dynamic expansion and rapid rollback, which is very convenient. The docker-maven-plugin plug-in is designed to help us automatically generate images and push them to the repository through simple configuration in the Maven project.

* * function:

When compiling the project, docker image can be generated automatically, and it can also be pushed to the warehouse remotely. Only reasonable configuration is needed in the configuration file pom.xml of maven * *

Example 1 (automatic generation of docker images at compile time):

1. Maven configuration:

Com.spotify docker-maven-plugin 1.0.0 myserver:v1 ${project.basedir} / src/main/resources/docker false / ${project.build.directory} ${project.build.finalName} .jar

2. Then in the project's src\ main\ resources\ docker (the dockerDirectory directory configured above), create a file named Dockerfile as follows:

FROM java:8MAINTAINER blueADD mydocker-0.0.1-SNAPSHOT.jar mydocker.jarENTRYPOINT ["java", "- jar", "/ mydocker.jar"]

3. Set the system environment variable to specify the host and port of the docker daemon to which you need to connect.

As mentioned earlier, docker is the Cramp S architecture, docker-maven-plugin plays the role of client, and the server needs to specify the environment variable.

4. Execute mvn clean install docker:build, build the image automatically after the project is compiled, and execute docker images to check whether the image exists:

Example 2 (image push to the warehouse, based on example 1):

1. Open the maven configuration file setting.xml, and add the warehouse account information:

Docker-hub blueiii xxxx xxxxx@163.com

2. To modify the pom.xml file, the imageName must be the same as the repository path:

Blueiii/mydocker:v1

3. Modify the pom.xml file and add the following configuration

Truedocker-hub https://hub.docker.com/

4. Also execute mvn clean install docker:build, automatically build an image and upload it to docker hub:
