idea combines docker to realize image packaging and one-click deployment

1. Install Docker on the server

yum install docker

Modify the configuration file and open port 2375

[root@microservice ~]# vim /usr/lib/systemd/system/docker.service

Add -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock after ExecStart=/usr/bin/dockerd-current \
Reload the configuration file and start:

systemctl daemon-reload
systemctl start docker

Appendix: Docker operation related commands

The systemctl command is a system service manager command, which is a combination of the service and chkconfig commands.
Start Docker: systemctl start docker
Stop Docker: systemctl stop docker
Restart Docker: systemctl restart docker Check the docker status: systemctl status docker
Start at boot: systemctl enable docker

2. Idea installation docker support plug-in and configuration

1.idea downloads docker support plug-in: Docker integration

(Shortcut key Crtl+shift+A, search for Docker integration, then enable it, restart idea to take effect)

2. IDEA Docker plugin configuration

File–>Settings–>Build,Execution,Deployment–>Docker–>Configure as follows:

tcp://server ip address:2375

Note: As long as the following prompts Connection successfl, it means the connection is successful;

3. Configure the pom file:

<build>
  <finalName>${project.artifactId}</finalName>
  <plugins>
    <plugin>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-maven-plugin</artifactId>
      <configuration>
        <fork>true</fork>
      </configuration>
    </plugin>
    <!-- Skipping unit tests -->
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-surefire-plugin</artifactId>
      <configuration>
        <skipTests>true</skipTests>
      </configuration>
    </plugin>
    <!--Use the docker-maven-plugin plugin-->
    <plugin>
      <groupId>com.spotify</groupId>
      <artifactId>docker-maven-plugin</artifactId>
      <version>1.0.0</version>
      <!--Bind the plugin to a certain phase for execution-->
      <executions>
        <execution>
          <id>build-image</id>
          <!--Users only need to execute mvn package, and mvn docker:build will be automatically executed-->
          <phase>package</phase>
          <goals>
            <goal>build</goal>
          </goals>
        </execution>
      </executions>
      <configuration>
        <!--Specify the generated image name-->
        <imageName>fred/${project.artifactId}</imageName>
        <!--Specify tags-->
        <imageTags>
          <imageTag>latest</imageTag>
        </imageTags>
        <!-- Specify the Dockerfile path -->
        <dockerDirectory>src/main/docker</dockerDirectory>
        <!--Specify the remote docker api address-->
        <dockerHost>http://server ip address:2375</dockerHost>
        <!-- Here is the configuration for copying the jar package to the specified directory of the docker container-->
        <resources>
          <resource>
            <targetPath>/</targetPath>
            <!--The path where the jar package is located corresponds to the target directory -->
            <directory>${project.build.directory}</directory>
            <!-- The jar package that needs to be included, which corresponds to the file name added in Dockerfile-->
            <include>${project.build.finalName}.jar</include>
          </resource>
        </resources>
      </configuration>
    </plugin>
  </plugins>
</build>

Attached project directory structure:

4. Write Dockerfile in the root directory

# Dockerfile
# Based on the image FROM openjdk:8-jdk-alpine
 
VOLUME /opt/tmp
 
ADD sg-business.jar app.jar
 
# -Djava.security.egd=file:/dev/./urandom can solve the problem that tomcat may start slowly# For details, please see: https://www.cnblogs.com/mightyvincent/p/7685310.html
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
 
# External port EXPOSE 8081

5. Click on the Maven package to build

Build a successful message

6. Click on the docker at the bottom to go to the docker interface. Double-click docker to connect to the server. Docker will display the docker image on the server. Find the image just generated (2 in the figure) and click Create Container.

7. Configure the docker container to expose the port and project interface port, then run to start the container

Finally, after setting up, start the container. After the startup is successful, go to Alibaba Cloud to check whether it is started successfully.
