前期准备：

1. 一个服务器安装好docker-ce，docker-compose
2. 准备好自己的域名 my.yuming.com
   详情请查看

部署步骤:

1. 做一个docker-compose.yaml

2. #docker-compose.yaml
   version: '3'
   services:
     bitwarden:
       image: bitwardenrs/server
       restart: always
       volumes:
         - ./bw-data/:/data
       environment:
         WEBSOCKET_ENABLED: 'true'
         SIGNUPS_ALLOWED: 'false'     # 不允许注册,第一次设置为true，注册好之后，再关闭
         INVITATIONS_ALLOWED: 'false' 
     caddy:
       image: abiosoft/caddy
       restart: always
       volumes:
         - ./Caddyfile:/etc/Caddyfile:ro    #事先建好Caddyfile文件
         - caddycerts:/root/.caddy
       ports:
         - 80:80   # needed for Let's Encrypt
         - 443:443
       environment:
          ACME_AGREE: 'true'       
          DOMAIN: 'my.yuming.com'  # 改成你的域名
          EMAIL: '12345678@qq.com'  # 改成你的邮箱
   volumes:
     caddycerts:     
   

3. 准备好Caddyfile文件

4. # Caddyfile
   {$DOMAIN} {
       tls {$EMAIL}
   
       header / {
           # Enable HTTP Strict Transport Security (HSTS)
           Strict-Transport-Security "max-age=31536000;"
           # Enable cross-site filter (XSS) and tell browser to block detected attacks
           X-XSS-Protection "1; mode=block"
           # Disallow the site to be rendered within a frame (clickjacking protection)
           X-Frame-Options "DENY"
           # Prevent search engines from indexing (optional)
           #X-Robots-Tag "none"
       }
   
       # The negotiation endpoint is also proxied to Rocket
       proxy /notifications/hub/negotiate bitwarden:80 {
           transparent
       }
   
       # Notifications redirected to the websockets server
       proxy /notifications/hub bitwarden:3012 {
           websocket
       }
   
       # Proxy the Root directory to Rocket
       proxy / bitwarden:80 {
           transparent
       }
   }
   

5. 运行docker-compose up -d

6. https://my.yuming.com 使用即可
