SpringBoot(一): 使用Docker打包SpringBoot并Push到DockerHub

SpringBoot: 2.1.1
com.spotify.dockerfile-maven-plugin: 1.4.8

1. Docker打包

1.1 修改application.yml

spring:
  profiles:
    active: @spring.profiles.active@

** @spring.profiles.active@中的pring.profiles.active与pom.xml->profiles->profile->properties->spring.profiles.active标签名称一致.**
**对于多环境的配置文件,SpringBoot提供了Profile功能来,因此在项目的resources目录下创建application-{profile的名称(与pom.xml->profile->id属性值保持一致)}.yml(或.properties)格式文件,并在打包或者运行时指定Profile即可.配置文件的名称,参考如下图所示: **

表明只有两个profile:dev和test

1.2 Dockerfile

FROM openjdk:8-jdk-alpine3.7
VOLUME /tmp

ARG JAR_FILE
ADD target/${JAR_FILE} target/app.jar

EXPOSE 8080

RUN touch target/app.jar
ENTRYPOINT ["java","-jar","target/app.jar"]

1.3 配置pom.xml

添加如下内容:

	<properties>
		<project.build.sourceEncoding>UTF-8project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8project.reporting.outputEncoding>
		<java.version>1.8java.version>
        <dockerfile-maven-version>1.4.8dockerfile-maven-version>
        <docker.image.prefix>star936docker.image.prefix>
        <docker.repository.name>rest-api-mybatisdocker.repository.name>
	properties>

1.2 打包

参照下图:

• 第一步: 勾选Profile;
• 第二步: 选中Lifecycle->clean并运行;
• 第三步: 选中Lifecycle->package并运行.

2. Push镜像到DockerHub私有仓库

2.1 配置Maven的setting.xml

添加如下内容:

<servers>
    <server>
        <id>docker.ioid>
        <username>DockerHub用户名username>
        <password>DockerHub密码password>
        <configuration>
        <email>DockerHub注册邮箱email>
        configuration>
    server>
servers>

2.2 Push

参照上图选中Plugins->dockerfile->dockerfile:push并运行.
