idea连接docker实现一键部署的方法

原作者: [db:作者] 来自: [db:来源] 收藏邀请

1.修改docker配置文件，打开2375端口

[root@s162 docker]# vim /usr/lib/systemd/system/docker.service
#查找 ExecStart，在末尾添加
#后面加上-H tcp://0.0.0.0:2375 

[root@s162 docker]# systemctl daemon-reload
[root@s162 docker]# systemctl start docker

## 查看2375端口是否启用
[root@s162 docker]# lsof -i:2375
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
dockerd 27021 root 5u IPv6 352598799  0t0 TCP *:2375 (LISTEN)

2. Idea安装配置docker插件

2.1. idea-plugins市场安装docker插件

略…

2.2. 配置docker

3.springboot项目部署到docker服务器

3.1. 编写docker/dockerfile

3.2.maven添加docker-maven-plugin插件

 <plugin>
   <groupId>com.spotify</groupId>
   <artifactId>docker-maven-plugin</artifactId>
   <version>1.0.0</version>
   <configuration>
    <!--指定生成的镜像名，如果不指定tag,默认会使用latest-->
    <imageName>jhs/${project.artifactId}:${project.version}</imageName>
    <!--添加额外的指定标签, 非必须-->
    <!--
    <imageTags>
     <imageTag>${project.version}</imageTag>
    </imageTags>
    -->

    <!-- 指定 Dockerfile 路径 ：项目根路径下-->
    <dockerDirectory>${project.basedir}/docker</dockerDirectory>
    <!--指定远程 docker api地址-->
    <dockerHost>http://192.168.129.162:2375</dockerHost>


    <!-- copy资源 -->
    <resources>
     <resource>
      <targetPath>/</targetPath>
      <directory>${project.build.directory}</directory>
      <include>${project.build.finalName}.jar</include>
     </resource>
    </resources>


    <!--docker build dockerfile时：设置镜像创建时的变量 -->
    <buildArgs>
     <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
    </buildArgs>
   </configuration>
  </plugin>

3.3. docker:build

使用命令$ mvn clean package docker:build -Dmaven.test.skip=true构建镜像，在docker服务器上查看镜像是否上传成功：

3.4 docker:tag

docker命令行格式为：#docker tag <imageId or imageName> <nexus-hostname>:<repository-port>/<image>:<tag>

插件配置
<configuration>补充配置：

 <configuration>
	 <image>jhs/${project.artifactId}:${project.version}</image>
  <!-- docker tag 打标签-->
  <newName>192.168.129.160:5000/${project.artifactId}:${project.version}</newName>
</configuration>

为镜像打上tag标签，为后续的push做准备：mvn clean docker:tag -Dmaven.test.skip=true -DskipDockerBuild

3.5 docker:push

插件配置
<configuration>补充配置：

<configuration>
	 <!-- docker push 推送到远程镜像仓库-->
  <!-- serverId: 为在maven setting.xml配置的server信息id-->
  <serverId>nexus-docker-registry</serverId>
  <registryUrl>192.168.129.160:5000</registryUrl>
  	
  	<!-- 打上tag的新镜像 push 到nexus-->
		<imageName>192.168.129.160:5000/${project.artifactId}</imageName>
</configuration>

将上文打上tag标签的镜像，推送到私服nexus：mvn clean docker:push -Dmaven.test.skip=true -DskipDockerBuild -DskipDockerTag

3.6 docker插件参数

-DskipDockerBuild to skip image build
-DskipDockerTag to skip image tag
-DskipDockerPush to skip image push
-DskipDockerto skip any Docker goals

3.7 绑定命令到maven phases

<executions>
  <execution>
   <id>build-image</id>
   <phase>package</phase>
   <goals>
    <goal>build</goal>
   </goals>
  </execution>

  <execution>
   <id>tag-image</id>
   <phase>package</phase>
   <goals>
    <goal>tag</goal>
   </goals>
   <configuration>
    <image>jhs/${project.artifactId}:${project.version}</image>
    <newName>192.168.129.160:5000/${project.artifactId}:${project.version}</newName>
   </configuration>
  </execution>


  <execution>
   <id>push-image</id>
   <phase>deploy</phase>
   <goals>
    <goal>push</goal>
   </goals>
   <configuration>
    <!-- docker push 推送到远程镜像仓库-->
    <!-- serverId: 为在maven setting.xml配置的server信息id-->
    <serverId>nexus-docker-registry</serverId>
    <registryUrl>192.168.129.160:5000</registryUrl>
    <imageName>192.168.129.160:5000/${project.artifactId}</imageName>
   </configuration>
  </execution>

 </executions>

3.8 最佳实践

 <properties>
  <docker.host>http://192.168.129.162:2375</docker.host>
  <docker.registry.url>192.168.129.160:5000</docker.registry.url>
 </properties>
 
<build>
 <plugins>
 	<plugin>
  <groupId>com.spotify</groupId>
  <artifactId>docker-maven-plugin</artifactId>
  <version>1.0.0</version>
  <configuration>
   <imageName>dic/${project.artifactId}:${project.version}</imageName>
   <!--添加额外的指定标签（可配置多个）, 若果没做指定，则为latest-->
   <!--
    <imageTags>
     <imageTag>${project.version}</imageTag>
    </imageTags>
    -->


   <!-- 指定 Dockerfile 路径 ：项目根路径下-->
   <dockerDirectory>${project.basedir}/docker</dockerDirectory>
   <!--指定远程 docker api地址-->
   <dockerHost>${docker.host}</dockerHost>


   <!-- copy资源 -->
   <resources>
    <resource>
     <targetPath>/</targetPath>
     <directory>${project.build.directory}</directory>
     <include>${project.build.finalName}.jar</include>
    </resource>
   </resources>


   <!--docker build dockerfile时：设置镜像创建时的变量 -->
   <buildArgs>
    <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
   </buildArgs>
  </configuration>

  <executions>
   <execution>
    <id>build-image</id>
    <phase>package</phase>
    <goals>
     <goal>build</goal>
    </goals>
   </execution>

   <execution>
    <id>tag-image</id>
    <phase>package</phase>
    <goals>
     <goal>tag</goal>
    </goals>
    <configuration>
     <image>dic/${project.artifactId}:${project.version}</image>
     <newName>${docker.registry.url}/${project.artifactId}:${project.version}</newName>
    </configuration>
   </execution>


   <execution>
    <id>push-image</id>
    <phase>deploy</phase>
    <goals>
     <goal>push</goal>
    </goals>
    <configuration>
     <!-- docker push 推送到远程镜像仓库-->
     <!-- serverId: 为在maven setting.xml配置的server信息id-->
     <serverId>nexus-docker-registry</serverId>
     <registryUrl>${docker.registry.url}</registryUrl>
     <imageName>${docker.registry.url}/${project.artifactId}</imageName>
    </configuration>
   </execution>

  </executions>
 </plugin>
 </plugins>
 </build>
