This article will explain in detail how to use Maven to package the springboot project into a docker image. Xiaobian thinks it is quite practical, so share it with you as a reference. I hope you can gain something after reading this article.

Maven packaged as docker image

Due to work reasons, the springboot project needs to be packaged into docker images through maven. Previously, I thought it could only be done on linux. Recently, I investigated it and it can also be packaged in window environment.

The following is an example of thinkpad E470, Windows 10 operating system and Eclipse development integration tool.

1. Add docker plugin dependency

First of all, Springboot project needs to add support for docker plug-in in pom.xml file. The latest plug-in is dockerfile-maven-plugin. The original plug-in is docker-maven-plugin, which is not recommended now.

The latest version 1.4.10 is used here.

2. Configuration of docker plugin

3. Write Dockerfile

Where JAR_FILE corresponds to JAR_FILE in the pom file buildArgs.

4. Maven command packaging

In the root directory of the springboot project, open the command window and execute: mvn clean package dockerfile:build, wait for it to be packaged:

Check whether the image is successful by docker command:

5. Precautions

Dockerfile file needs to be in the root directory of the project, juxtaposed with pom.xml.

The default port for a new springboot project is 8080.

3. Add the following to Maven's settings.xml file:

com.spotify

Otherwise, the following error will be reported:

4. Execute the command: mvn clean package dockerfile:build, not mvn clean package docker:build, which is an old version command. If you execute this command, you will report the following error:

mvn clean package dockerfile:build still reports error

Check the following options in Docker configuration, Docker settings:

6, private service

Dokcer installation is complete, the default image is downloaded from its official website, the speed is relatively slow, you can Baidu

Find some domestic repositories, such as Ali's: https://de13k09g.mirror.aliyuncs.com,

Then configure it in DockerEngine as follows:

Click Apply & Restart, if it can restart successfully, it means that the configuration is successful.

6, Install docker under Window10

Register docker users on docker's official website (https://www.docker.com/) to download. After the installation file download is complete, it is an exe executable file, double-click to execute, and wait for the installation to complete.

After installation, docker may not start successfully, such as:

Then, you need to open the following functions.

Hyper-V is open.

Control Panel-Programs-Programs and Features, click Start or Close Windows Features, check Hyper-v.

2. BIOS opens virtualization

Go to BIOS, find configuration, select virtualization and set it to Enable.

Confirm whether the machine virtualization is started successfully. You can view it from Task Manager: Performance-CPU
