idea连接docker实现一键部署的方法

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>

 </properties>
 
<build>
 <plugins>

  <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>
