Conmi的正确答案——docker-compose的“Ports are not available”解决方案（20220315093448）

系统：Windows 10 专业版 20H2 19042.1415
docker版本：20.10.11, build dea9396

docker-compose.yaml：

version: "3"
services:
  mysql:
    image: "mysql:5.7"
    restart: always
    ports:
      - "3306:3306"
    environment:
      MYSQL_ROOT_PASSWORD: "123456"

报错日志：

Creating docker_mysql_1 ... error

ERROR: for docker_mysql_1  Cannot start service mysql: Ports are not available: listen tcp 0.0.0.0:3306: bind: An attempt was made to access a socket in a way forbidden by its access permissions.

端口扫描：

netstat -ano | findstr :3306

如果这里返回占用了端口的应用则不用看下面了，直接“taskkill /f /pid 这个应用的PID”，然后“docker-compose up”你的yaml即可启动。
