这篇文章主要介绍了在Idea中使用Docker部署SpringBoot项目的详细教程，本文给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下

前言

项目需要：

安装Docker idea中安装docker插件，并配置docker一个SpringBoot项目创建Dockerfile

一、下载、安装、配置Docker下载Docker

下载地址：官网下载 Docker

安装

一直下一步就行

配置路径：Settings–General 勾选 Expose daemon on tcp://localhost:2375 without TLS

测试是否安装成功

				?

									C:\Users\msi>docker -v

									Docker version 19.03.12, build 48a66213fe

									C:\Users\msi> docker run hello-world

									Hello from Docker!

									This message shows that your installation appears to be working correctly.

									To generate this message, Docker took the following steps:

									 1. The Docker client contacted the Docker daemon.

									 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.

									  (amd64)

									 3. The Docker daemon created a new container from that image which runs the

									  executable that produces the output you are currently reading.

									 4. The Docker daemon streamed that output to the Docker client, which sent it

									  to your terminal.

									To try something more ambitious, you can run an Ubuntu container with:

									 $ docker run -it ubuntu bash

									Share images, automate workflows, and more with a free Docker ID:

									 https://hub.docker.com/

二、Idea 安装Docker插件

1.安装docker插件在idea中： file--Plugins--Marketplace 搜索 Docker 安装

2.配置Docker服务

file – 搜索docker – 选择Docker – 右侧添加一个Docker
Connection successful 显示，表示 Docker链接成功

三、创建SpringBoot项目，修改pom.xmlspringMVC 项目，访问 localhost:8080/hello 显示 hello 字符串

				?

									@RequestMapping("/hello")

									  @ResponseBody

									  public String hello () {

									    return "hello";

									  }

1.配置pom.xml 文件

				?

									<build>

									    <plugins>

									      <plugin>

									        <groupId>org.springframework.boot</groupId>

									        <artifactId>spring-boot-maven-plugin</artifactId>

									        <executions>

									          <execution>

									            <goals>

									              <goal>repackage</goal>

									            </goals>

									          </execution>

									        </executions>

									      </plugin>

									      <plugin>

									        <groupId>com.spotify</groupId>

									        <artifactId>docker-maven-plugin</artifactId>

									        <version> 1.2.1</version>

									        <executions>

									          <execution>

									            <id>build-image</id>

									            <phase>package</phase>

									            <goals>

									              <goal>build</goal>

									            </goals>

									          </execution>

									        </executions>

									        <configuration>

									          <imageName>${project.artifactId}</imageName>

									          <imageTags>

									            <imageTag>latest</imageTag>

									          </imageTags>

									          <dockerDirectory>${project.basedir}</dockerDirectory>

									          <dockerHost>http://localhost:2375</dockerHost>

									          <resources>

									            <resource>

									              <targetPath>/</targetPath>

									              <directory>${project.build.directory}</directory>

									              <include>${project.build.finalName}</include>

									            </resource>

									          </resources>

									        </configuration>

									      </plugin>

									    </plugins>

									  </build>

2.创建Docker 文件

在main文件夹下创建一个docker文件夹，并在里面创建一个Dockerfile文件。xxxxx.jar 是使用maven打包后复制进来的。

Dockerfile 文件内容:

				?

									# From java image, version : 8

									FROM java:8

									# 挂载app目录

									VOLUME /app

									# COPY or ADD to image

									COPY demo-0.0.1-SNAPSHOT.jar app.jar

									RUN bash -c "touch /app.jar"

									EXPOSE 8080

									ENTRYPOINT ["java", "-jar", "app.jar"]
