Detailed process of installing the docker plugin in IntelliJ IDEA (2018 version)

1. Development Environment

2. Install the docker plugin

1. Installation in Idea

Open Idea, go to File->Settings->Plugins->Install JetBrains plugin to enter the plugin installation interface, enter docker in the search box, you can see Docker integration, click the Install button on the right to install it. Restart Idea after installation.

After restarting, configure docker and connect to the remote docker service. Open the configuration interface from File->Settings->Build,Execution,Deployment->Docker.

Click the + sign to add a docker configuration, enter the Name and Engine API URL. The URL is the docker service address, and docker needs to enable the remote connection function. In CentOS, add the following configuration to the docker startup parameters to enable remote connection.

Configuration file location: /usr/lib/systemd/system/docker.service, configuration parameter item: ExecStart

-H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375

2. Download the installation package and install it

Download the docker installation package from the JetBrains official website (http://plugins.jetbrains.com/plugin/7724-docker-integration), open Idea after downloading, open the file selection interface from File->Settings->Plugins->Install plugin from disk, select the zip installation package you just downloaded, and restart Idea after installation. The configuration is as above.

3. Spring Boot service docker deployment

1. Create a new Spring Boot project

You can refer to the sample project https://github.com/sealire/people/tree/tutorial and write a REST interface in the project as follows, which simply returns a string.

@RequestMapping(value = "test", method = RequestMethod.GET)
@ResponseBody
public Object test(HttpServletRequest request, @RequestParam String param) {
    return param;
}

Modify the pom file, add properties, and add plugin:

<properties>
    <docker.image.prefix>leesia</docker.image.prefix>
</properties>
 
<build>
	<plugins>
		<plugin>
			<groupId>com.spotify</groupId>
			<artifactId>docker-maven-plugin</artifactId>
			<version>1.0.0</version>
			<configuration>
				<imageName>${docker.image.prefix}/${project.artifactId}</imageName>
				<dockerDirectory></dockerDirectory>
				<resources>
					<resource>
						<targetPath>/</targetPath>
						<directory>${project.build.directory}</directory>
						<include>${project.build.finalName}.jar</include>
					</resource>
				</resources>
			</configuration>
		</plugin>
	</plugins>
</build>

2. Configure the Dockerfile file

Create a new Dockerfile file in the project root directory with the following content:

FROM java:8
VOLUME /tmp
COPY target/resource-1.0-SNAPSHOT.jar resource.jar
RUN bash -c "touch /resource.jar"
EXPOSE 8080
ENTRYPOINT ["java","-jar","resource.jar"]
 
# docker run -d -p 18080:8080 --name docker-resource leesia/resource:1.0

The base image is java:8, and the copy command copies the resource jar under /target to the image. ENTRYPOINT is the command to start the container.

3. Create a Docker image

Package the project and execute the mvn clean package command in the idea Terminal to compile and package it. After packaging, a jar package will be generated in the target directory.

After generating the jar package, you can start the service locally for testing. After testing, configure the Docker image creation command. Enter the configuration interface from Run->Edit Configrations.

Click Docker, then click the + sign, add a docker command, enter Name, select Server, select the Dockerfile file, enter the image tag, and complete the configuration.

After the configuration is complete, execute this command,

If there are no errors, the Docker server will be connected and the image will be created. After creating the image, start the image on the Docker server and execute the following command to start the image:

docker run -d -p 18080:8080 --name docker-resource leesia/resource:1.0

-p binds the Docker server's port 18080 to the container's port 8080.

After the container is started, access the service interface. The interface parameter is a string and the character is returned.
