docker security_opt

使用 mysql 容器时，如果没设置 seccomp:unconfined，mysql 日志会报 mbind: Operation not permitted。

例子，

version: '3.8'
services:
  db:
    image: mysql:8.0
    command: --default-authentication-plugin=mysql_native_password
    restart: always
    environment:
      MYSQL_DATABASE: website
      MYSQL_ROOT_HOST: '%'
      MYSQL_ROOT_PASSWORD: test
    security_opt:
    - seccomp:unconfined
    ports:
    - 13306:3306
