IDEA部署Docker到WSL2的详细过程

本地环境 Windows10+WSL2(Ubuntu)，需要大家在服务器安装 Docker 之后，开启远程访问

sudo vi /etc/default/docker 修改配置

# 开启远程访问 -H tcp://0.0.0.0:2375
# 开启本地套接字访问 -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 重启

Idea 安装 Docker 插件后，设置填写地址 tcp://192.168.50.28:2375 （自己的本机 IP 地址），成功连接的话有 Connection Successful 提示

Tools 选项配置，需要先安装 Windows 版本 Docker，装完把程序关掉，开机自启关掉，因为我不想多开一个程序，Ubuntu 里已经有 Docker 了，这里只是要用到 docker-compose.exe 在 Windows 环境做下容器编排而已。Docker Machine 用不着的话不用管。

一般的 Dockerfile 文件和 docker-compose.yml 文件参考

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 #宿主机 jdk 映射给容器使用
    tty: true
    network_mode: bridge
    restart: always

使用 Docker-compose 创建 Docker 容器

Compose files 选择刚创建的 docker-compose.yml 文件

运行

Deploying 'Compose: lin-test'...
"C:\Program Files\Docker\Docker\resources\bin\docker-compose.exe" -f D:\Project\gitFile\lin\lin-test\docker-compose.yml up -d
