自用的vaultwarden docker-compse设置，空着的参数请自行查阅文档。首次使用先把SIGNUPS_ALLOWED设置为true，注册账号后再设置false关闭注册。

docker-compose.yml

services:
  vaultwarden:
    image: vaultwarden/server:latest-alpine
    container_name: vaultwarden
    restart: unless-stopped
    environment:
      SIGNUPS_ALLOWED: false
      WEBSOCKET_ENABLED: true
      PUSH_ENABLED: true
      PUSH_INSTALLATION_ID: 
      PUSH_INSTALLATION_KEY: 
      PUSH_RELAY_URI: https://api.bitwarden.eu
      PUSH_IDENTITY_URI: https://identity.bitwarden.eu
      ADMIN_TOKEN: 
      DOMAIN: 
      TIME_ZONE: "Asia/Shanghai"
    volumes:
      - ./vw_data/:/data/
    networks:
      - vaultwarden-network

  vaultwarden-cf-tunnel:
    container_name: vaultwarden-cf-tunnel
    image: cloudflare/cloudflared:latest
    command: tunnel run --token "token"
    restart: unless-stopped
    user: root
    networks:
      - vaultwarden-network

networks:
  vaultwarden-network:
    name: vaultwarden-network
    external: false

不需要使用cloudflare的tunnel服务把vaultwarden暴露到外网的用户，把vaultwarden-cf-tunnel整段删掉即可
