1、编写docker-compose.yml文件

version: "3.1"
services:
  nacos:
    restart: always
    image: nacos/nacos-server:v2.2.3
    container_name: nacos
    environment:
    - NACOS_AUTH_ENABLE=true
    - MODE=standalone
    - NACOS_AUTH_TOKEN=8b92c609089f74db3c5ee04bd7d4d89e8b92c609089f74db3c5ee04bd7d4d89e 
    - NACOS_AUTH_IDENTITY_KEY=nacos 
    - NACOS_AUTH_IDENTITY_VALUE=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJkYXRhIjpbeyJ4eHh4IjoieXl5In1dLCJpYXQiOjE2Nzk1NzU0NzIsImV4cCI6MTY3OTUwMDc5OSwiYXVkIjoiIiwiaXNzIjoiIiwic3ViIjoiIn0.nhN_hKcnjlX0QW-kQj2beLehBzrQnB1IhhJZe2WO-c0 
    volumes:
    - ./data:/home/nacos/data
    ports:
