Maven构建Docker镜像并且Push

允许Docker远程访问（可选）

1. 编辑docker的宿主机文件/lib/systemd/system/docker.service

   $ vi /lib/systemd/system/docker.service
   # ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock后面加上-H 0.0.0.0:2375
   ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock后面加上-H 0.0.0.0:2375
   $ wq!
   

2. 重启服务

   $ systemctl daemon-reload
   $ service docker restart
   

3. 验证

   访问：http://192.168.246.135:2375/info，能出现数据就表示开启成功

IDEA 配置docker-maven-plugin

1. 创建Spring Boot项目，这一步略

2. 配置pom.xml

   
   
       4.0.0
       
           org.springframework.boot
           spring-boot-starter-parent
           2.6.1
            
       
       com.pasca
       student-docker
       latest
       Student-Docker
       Student-Docker
       
           1.8
           192.168.246.135:2375
           pasca
       
       
           ...其他项目依赖省略
       
   
       
           
               ...其他插件省略
               
               
                   com.spotify
                   docker-maven-plugin
                   1.2.2
   
                   
                   
                       
                           build-image
                           
                           package
                           
                               build
                           
                       
                   
   
                   
                       
                       pasca/${project.artifactId}
                       
                       
                           ${project.version}
                       
                       
                       ${project.basedir}/src/main/resources
   
                       
                       http://192.168.246.135:2375
   
                       
                       
                           
                               /
                               
                               ${project.build.directory}
                               
                               ${project.build.finalName}.jar
                           
                       
                   
               
           
       
   
   

3. 编写Dockerfile

   FROM bitnami/java:1.8.312
   
   MAINTAINER Docker Practice Project by Pasca
   
   ADD *.jar app.jar
   
   ENV TZ Asia/Shanghai
   EXPOSE 8080
   ENTRYPOINT ["java","-jar","/app.jar"]
   

4. 制作镜像mvn package

   经过这一步，本地项目已经在远程服务上面创建了镜像

5. 编写docker-compose.yaml

   version: '3.8'
   services:
     pasca-app-student:
       image: pasca/student-docker:latest
       container_name: pasca-app-student
       restart: always
       ports:
         - '8080:8080'
   

6. 启动docker compose up -d
