Install Vaultwarden

1. 1. Install Docker from its official repository, as on our Docker page

2. 2. Start Vaultwarden, listening on this machine only

   mkdir /vw-data
   docker run -d --name vaultwarden --restart unless-stopped \
     -v /vw-data/:/data/ -p 127.0.0.1:8000:80 vaultwarden/server:latest

3. 3. Put Caddy in front for HTTPS, the web vault does not work without it

   apt install -y caddy
   
   vault.example.com {
       reverse_proxy 127.0.0.1:8000
   }

4. 4. Create your account, then restart the container with SIGNUPS_ALLOWED=false so nobody else can register

5. 5. Back up db.sqlite3 and the attachments folder every day with sqlite3 .backup, and keep a copy elsewhere
