Detailed process of deploying Docker to WSL2 in IDEA

The local environment is Windows 10 + WSL2 (Ubuntu). You need to install Docker on the server and enable remote access.

sudo vi /etc/default/docker modify configuration

# Enable remote access -H tcp://0.0.0.0:2375
# Enable local socket access -H unix:///var/run/docker.sock
DOCKER_OPTS="-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock"

sudo service docker restart restart

After installing the Docker plug-in in Idea, set the address tcp://192.168.50.28:2375 (your local IP address). If the connection is successful, there will be a Connection Successful prompt

To configure the Tools option, you need to install the Windows version of Docker first. After the installation, close the program and turn it off automatically when the computer starts, because I don’t want to open an extra program. Ubuntu already has Docker, so here I just need to use docker-compose.exe to do container orchestration in the Windows environment. Don't worry about Docker Machine if you don't need it.

General Dockerfile and docker-compose.yml file reference

FROM ubuntu:latest

COPY target/*.jar /app.jar

ENV JAVA_HOME="/usr/lib/jdk1.8"

ENV PATH="${PATH}:${JAVA_HOME}/bin:${JAVA_HOME}/sbin"

ENTRYPOINT [ "java", "-jar", "/app.jar" ]

version: '3'
services:
  last:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "18080:8080"
    volumes:
      - /usr/lib/jvm/java-8-openjdk-amd64:/usr/lib/jdk1.8 #Host jdk maps to container using tty: true
    network_mode: bridge
    restart: always

SECURITY WARNING: You are building a Docker image from Windows against a non-Windows Docker host. All files and directories added to build context will have '-rwxr-xr-x' permissions. It is recommended to double check and reset permissions for sensitive files and directories.

Use 'docker scan' to run Snyk tests against images to find vulnerabilities and learn how to fix them
