Implementation of Docker project deployment in IDEA? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Docker configuration

Modify the configuration file

Open the Docker configuration file: vim / usr/lib/systemd/system/docker.service comment out the following line: # ExecStart=/usr/bin/dockerd-H fd://-- containerd=/run/containerd/containerd.sock write a new line: ExecStart=/usr/bin/dockerd-H tcp://0.0.0.0:2375-H unix:///var/run/docker.sock reload configuration file and boot: systemctl daemon-reloadsystemctl start docker

As shown in the following figure:

IDEA configuration Docker

Install the Docker plug-in

Configure Docker information

To configure Docker in the settings, you need to configure API URL. Connection successful appears as follows:

Project building

Create a new springboot project

To build a project through IDEA, you don't need to choose anything, just go to the next step:

Modify the pom file

There are two main points:

Add to the 1.properties tag

Demo

two。 Add a new plugin tag

Com.spotify docker-maven-plugin 1.2.1 ${docker.image.prefix} / ${project.artifactId} / ${project.build.directory} ${project.build.finalName} .jar

Here is the complete pom file:

4.0.0 org.springframework.boot spring-boot-starter-parent 2.2.1.RELEASE com.example demo 0.0.1 demo Demo project for Spring Boot 1.8 demo org.springframework.boot spring-boot-starter org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-test test org.junit .vintage junit-vintage-engine org.springframework.boot spring-boot-maven-plugin com.spotify docker-maven-plugin 1.2.1 ${docker.image.prefix} / ${project.artifactId} / ${ Project.build.directory} ${project.build.finalName} .jar

Create a new Dockerfile file

Need to create a new Dockerfile file in the root directory

# specify the basic image on which to customize FROM java:8# maintainer information MAINTAINER zhouzhaodong # the / tmp directory here will be automatically mounted as anonymous volumes at run time, and any information written to / tmp will not be recorded into the target/demo-1.0.0.jar in the container storage layer VOLUME / tmp# replication context directory and executed as COPY target/demo-0.0.1.jar demo-1.0.0.jar#bash in the container. Make demo-1.0.0.jar accessible to # RUN to create a new layer, execute these commands on it, and after execution, the changes in the commit layer form a new mirror. RUN bash-c "touch / demo-1.0.0.jar" # states that the runtime container provides a service port, which is just a declaration, and the service EXPOSE 808 will not open this port at run time because of this declaration. EXPOSE 808 specifies the container launcher and parameters "" ENTRYPOINT ["java", "- jar", "demo-1.0.0.jar"]

Create a new controller file

Don't forget to add web dependencies to the pom file.

@ RestControllerpublic class testController {@ RequestMapping ("/") public String test () {return "test Docker";}}

Maven packing

Install Packaging:

Generate the jar package:

New configuration

Create a new Dockerfile running configuration:

Add the following information, find the Dockerfile file you wrote, and configure the port mapping:

Generate Docker image and run it

Just run the Dockerfile running configuration you just created:

After a successful run, the log window will display the information about the project running:
