IDEA集成docker

IDEA 使用Docker

• 首先设置docker 可以远程连接

  在docker.service 文件中填写 [Service] ExecStart 后面 添加 -H tcp://0.0.0.0:2375 表示可以远程的连接

  vim /usr/lib/systemd/system/docker.service
  
  
  [Unit]
  Description=Docker Application Container Engine
  Documentation=https://docs.docker.com
  BindsTo=containerd.service
  After=network-online.target firewalld.service containerd.service
  Wants=network-online.target
  Requires=docker.socket
  
  [Service]
  Type=notify
  # the default is not to use systemd for cgroups because the delegate issues still
  # exists and systemd currently does not support the cgroup feature set required
  # for containers run by docker
  ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock
  ExecReload=/bin/kill -s HUP $MAINPID
  TimeoutSec=0
  RestartSec=2
  Restart=always
  
  # Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
  # Both the old, and new location are accepted by systemd 229 and up, so using the old location
  # to make them work for either version of systemd.
  StartLimitBurst=3
  
  # Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.
  # Both the old, and new name are accepted by systemd 230 and up, so using the old name to make
  # this option work for either version of systemd.
  StartLimitInterval=60s
  
  # Having non-zero Limit*s causes performance problems due to accounting overhead
  # in the kernel. We recommend using cgroups to do container-local accounting.
  LimitNOFILE=infinity
  LimitNPROC=infinity 
  LimitCORE=infinity
  
  

  查看 docker 的状态,可以查看docker 的容器状态以及本身的配置信息。

  systemctl status docker.service
  

  表示已经启动 ，并且可以查看到是否存在这个配置。

如果没有存在这个配置文件 ，需要重新启动docker

systemctl resatrt docker.service

• idea 下载docker 插件

  在设置里面去找Plugins ，下载docker 的插件

• idea 连接docker

  在idea 的settings 里面找到docker

可以看到连接成功，在Engine API URL 里面输入你的docker 所在的服务ip 以及刚刚输入的端口。

• idea 配置Dockerfile 文件

  FROM java:8 ## 依赖的docker 镜像
  VOLUME /tmp  ## 存放的临时文件夹
  ADD target/ruoyi.jar app.jar ## 添加的jar 文件
  ENTRYPOINT ["java","-jar","/app.jar"] ## 运行的Java jar 命令
  

  	
  	<build>
  		<finalName>${project.artifactId}</finalName>
  		<plugins>
  			<plugin>
  				<groupId>org.springframework.boot</groupId>
  				<artifactId>spring-boot-maven-plugin</artifactId>
  				<configuration>
  					<fork>true</fork> <!-- 如果没有该配置，devtools不会生效 -->
  				</configuration>
  			</plugin>
  			<plugin>
  				<groupId>com.spotify</groupId>
  				<artifactId>docker-maven-plugin</artifactId>
  				<version>1.2.0</version>
  				<executions>
  					<execution>
  						<id>build-image</id>
  						<phase>package</phase>
  						<goals>
  							<goal>build</goal>
  						</goals>
  					</execution>
  				</executions>
  				<configuration>
  					<dockerHost>http://sunbird.top:2375</dockerHost>
  					<imageName>javaboy/${project.artifactId}</imageName>
  					<imageTags>
  						<imageTag>${project.version}</imageTag>
  					</imageTags>
  					<forceTags>true</forceTags>
  					<dockerDirectory>${project.basedir}</dockerDirectory>
  					<resources>
  						<resource>
  							<targetPath>/</targetPath>
  							<directory>${project.build.directory}</directory>
  							<include>${project.build.finalName}.jar</include>
  						</resource>
  					</resources>
  				</configuration>
  			</plugin>
  		</plugins>
  	</build>
  
  

  在maven pom.xml 文件中填写以上的docker 编译文件 然后对用maven 对jar 进行编译 在进行 docker：build ，最后docker：push 上去。

可以通过docker 看到镜像
