Spring boot uses docker to build gradle project implementation steps

Preface

This is an article related to four knowledge points, namely java, docker, springboot and gradle. We hope to use the springboot framework in the Java environment to build a project through gradle, and then deploy and run the project in the docker container!

For more information about gradle, please refer to this article: //www.VeVB.COM/article/125602.htm

• Java runtime
• springboot open source scaffolding
• gradle's most popular project building tool
• The most popular container products of docker

I won’t say much below, let’s take a look at the detailed introduction:

Places to pay attention to

1. The project name is the mirror name, so it can only be in lowercase letters
2. The jar in build.gradle is the package generated by gradle build
3. Dockerfile is placed in the src/main/docker directory by default

Development process

A build.gradle file

 dependencies { classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}") classpath('se.transmode.gradle:gradle-docker:1.2') }apply plugin: 'java'apply plugin: 'eclipse'apply plugin: 'org.springframework.boot'apply plugin: 'io.spring.dependency-management'apply plugin: 'docker'version = '1.0.0'jar { baseName = 'springdemo'}task buildDocker(type: Docker, dependsOn: build) { push = true applicationName = jar.baseName dockerfile = file('src/main/docker/Dockerfile') doFirst { copy { from jar into stageDir } }}

Second compilation project

 docker build

Three generation mirror

 docker build buildDocker

Four run containers

 docker run -p 80:8080 springdemo-1.0.0
