How to use Docker plugin to remotely deploy projects to cloud servers in IDEA

1. Open port 2375

Edit docker.service

vim /lib/systemd/system/docker.service

Add configuration after ExecStart

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

Restart docker network and docker

systemctl daemon-reload
systemctl restart-docker

Centos7 open ports

firewall-cmd --zone=public --add-port=2375/tcp --permanent
firewall-cmd --reload

Check if the port is being monitored

netstat -lnp | grep 2375

If it is monitored, it proves success

Note: It is unsafe to expose port 2375. If you do not need to access port 2375 from the external network, close this port in time .
firewall-cmd --zone=pulic --remove-port=2375/tcp --permanent
Open the specified port to the specified IP: iptables -I INPUT -s IP -p tcp --dport 2375 -j ACCEPT

2. IDEA installs and configures the Docker plug-in

Install

After IDEA installs Docker Integration, restart IDEA.

Configuration

If the IP and port of the cloud server are correct, the connection will be successful as shown below.

Remote publishing project

Write a Spring Boot project for release. The port is configured as 8080

@RestController
@RequestMapping("hello")
public class HelloWebfluxController {

  @GetMapping("webflux")
  public Mono<String> mono(){
    return Mono.just("hello webflux");
  }

}

Pack

mvn clean package

Writing a Dockerfile

The Dockerfile is placed in the project root path.

FROM java:8
VOLUME /tmp
COPY target/hello-flux-0.0.1-SNAPSHOT.jar hello-flux.jar
RUN bash -c "touch /hello-flux.jar"
# 8080 port EXPOSE 8080
ENTRYPOINT ["java","-jar","hello-flux.jar"]
# docker run -d -p 8080:8080 --name docker-resource demo/hello-flux:1.0

It is also OK to put Dockerfile in src/main/resoures. The important thing is to indicate where the jar package to be run is.

Configuration

Specify the location of the Dockerfile in the configuration.

Bind ports Bind port mapping

Command line can manually enter other parameters

run

After clicking Run, wait for a moment.

The console prompts that the release is successful.

Check whether the remote host has successfully published the image.

Check whether the docker container is started in the remote host.

Successful access.
