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

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.

Image for service last was built because it did not already exist. To rebuild this image you must use `docker-compose build` or `docker-compose up --build`.
