Docker container launches Spring boot project

First, install the Docker environment

Yum Install Docker

Systemctl Start Docker.service

Systemctl Enable Docker.service

Next, use the Docker China accelerator

Vi/etc/docker/daemon.json

#添加后

Restart Docker

Systemctl Restart Docker

The installation was successful when you entered the Docker version to return the release information

Ii. Installation of JDK

Yum-y Install java-1.8.0-openjdk*

Next, with the environment variable open vim/etc/profile add a little bit of content

Export JAVA_HOME=/USR/LIB/JVM/JAVA-1.8.0-OPENJDK-1.8.0.171-7.B10.EL7.X86_64/JRE
Export path= $PATH: $JAVA _home/bin
After the modification is complete, make it effective

Source/etc/profile

Input Java-version return version information is installed normally

Third, install Maven

Download: http://mirrors.shu.edu.cn/apache/maven/maven-3/

There are several versions of Maven in this case, with apache-maven-3.5.3-bin.tar.gz.

#解压

Tar vxf apache-maven-3.5.3-bin.tar.gz

#移动

MV Apache-maven-3.5.2/usr/local/maven3

Modify the environment variables to add the following lines in the/etc/profile

Maven_home=/usr/local/maven3
Export Maven_home
Export Path=${path}:${maven_home}/bin
Remember to execute source/etc/profile to make the environment variable effective.

Then, enter Mvn-version to return the version information to install the normal

################# #到这里环境就配置完成了, the following is the real deployment of the part, because the process is tortuous, may be more detailed, pro-Test available ##############

Start with maven packaging, MVN clean packages, generate jar packs (Spring-boot-docker-0.0.1-snapshot.jar)

Write Dockerfile:

Next, create an empty directory, put Dockerfile and Spring-boot-docker-0.0.1-snapshot.jar in it, build the mirror

Docker build-t Huangll/springboot-docker. (Note that there is a small point here!!!) ）

That's probably how it's done.

To run the container:
Docker run-d--name springboot-p 8888:8888 spring-boot/spring-boot-docker

Docker PS Viewing container:

This is a successful release!!!
