Vaultwarden using Docker Compose with existing Certificates

Hello Friends,

I have a small ubuntu Server and I finally also want to transfer my Vaultwarden Instance to it. On this Server I have several services running (homeassistant, ...) and Certbot via Dehydrated (right now I get a certificate for my duckdns address). In some directory I have the privkey and fullchain files.

Now my Problem is that when I start vaultwarden it wont load as https.

I believe, my Problem is telling Vaultwarden, where my certificate files are located so it can use them accordingly.

This is my Compose File right now:

  vaultwarden:
    container_name: vaultwarden
    image: vaultwarden/server:latest
    restart: unless-stopped
    volumes:
      - /home/vaultwarden:/data/
      - /home/(directory to my certificates):/usr/share/ca-certificates/
    ports:
      - 8129:80
    environment:
      - DOMAIN=https://hurrdurr.duckdns.org
      - LOGIN_RATELIMIT_MAX_BURST=10
      - LOGIN_RATELIMIT_SECONDS=60
      - ADMIN_RATELIMIT_MAX_BURST=10
      - ADMIN_RATELIMIT_SECONDS=60
      - ADMIN_TOKEN=token
      - SENDS_ALLOWED=true
      - EMERGENCY_ACCESS_ALLOWED=true
      - WEB_VAULT_ENABLED=true
      - SIGNUPS_ALLOWED=true

The Volume Mapping to the certificates was just me trying it out so maybe its working if I map it like that.

If I open the 8129 in my Browser it will just time out. I also managed it to start but it wouldnt let me register as theres not https certificate.

Seconding a reverse proxy. Once you have it set up, it's trivial to add a subdomain, forward it to your internal port that your container is exposing, then use certbot or whatever to get a new certificate for that subdomain.

I just use apache because I heavily use it for work, so I already know it well. But lots of people swear by nginx as well. There are lots of other options as well.
- No need to get a certificate for ever subdomain, you can get a wildcard cert for *.your. domain.
  
  True. I did that for one of my domains, but it was really quite annoying to do with certbot, as you needed some sort of plugin.
- Thirding a reverse proxy. Probably Nginx Proxy Manager (NPM) is the easiest reverse proxy to get started with, if you don't want to deal with plain nginx config files

Here's the secret to stuff like this:

Run a single reverse proxy / edge router for all of your containerised services.

I recommend Traefik - https://gitlab.com/Matt.Jolly/traefik-grafana-prometheus-docker

You can configure services with labels attached to the container and (almost) never expose ports directly. It also lets you host an arbitrary number of services listening on 80/443.

An example config might look like this:

# docker-compose.yml
version: '3.9'

services:
  bitwarden:
    image: vaultwarden/server:latest
    restart: always
    volumes:
      - /data/vaultwarden/:/data
    environment:
#      - ADMIN_TOKEN=
      - WEBSOCKET_ENABLED=true
    networks:
      - proxy
    labels:
      - traefik.enable=true
      - traefik.http.routers.bitwarden-ui-https.tls.certresolver=letsencrypt
      - traefik.http.middlewares.redirect-https.redirectScheme.scheme=https
      - traefik.http.middlewares.redirect-https.redirectScheme.permanent=true
      - traefik.http.routers.bitwarden-ui-https.rule=Host(`my.domain.com`)
      - traefik.http.routers.bitwarden-ui-https.entrypoints=websecure
      - traefik.http.routers.bitwarden-ui-https.tls=true
      - traefik.http.routers.bitwarden-ui-https.service=bitwarden-ui
      - traefik.http.routers.bitwarden-ui-http.rule=Host(`my.domain.com`)
      - traefik.http.routers.bitwarden-ui-http.entrypoints=web
      - traefik.http.routers.bitwarden-ui-http.middlewares=redirect-https
      - traefik.http.routers.bitwarden-ui-http.service=bitwarden-ui
      - traefik.http.services.bitwarden-ui.loadbalancer.server.port=80
      - traefik.http.routers.bitwarden-websocket-https.rule=Host(`my.domain.com) &amp;&amp; Path(`/notifications/hub`)
      - traefik.http.routers.bitwarden-websocket-https.entrypoints=websecure
      - traefik.http.routers.bitwarden-websocket-https.tls=true
      - traefik.http.routers.bitwarden-websocket-https.service=bitwarden-websocket
      - traefik.http.routers.bitwarden-websocket-http.rule=Host(`my.domain.com`) &amp;&amp; Path(`/notifications/hub`)
      - traefik.http.routers.bitwarden-websocket-http.entrypoints=web
      - traefik.http.routers.bitwarden-websocket-http.middlewares=redirect-https
      - traefik.http.routers.bitwarden-websocket-http.service=bitwarden-websocket
      - traefik.http.services.bitwarden-websocket.loadbalancer.server.port=3012

Using traefik as your first reverse proxy might be a bit daunting. Caddy or "nginx reverse proxy" are much easier to configure.
- If you want it beginner friendly, I can recommend nginx proxy Manager, which is basically a web ui frontend for nginx. This has its own drawbacks, but makes setup very uncomplicated.

I use Nginx Proxy Manager to reverse proxy all my services including Vaultwarden -

Setup in NPM -

Open Nginx Proxy Manager Admin Portal
Click Proxy Hosts
Click Add Proxy Host
Fill in the details
    Details tab
        Domain Names - vault.your.domain
        Scheme - http
        Forward Hostname/IP - vaultwarden (this should be the name of your vw container)
        Forward Port - 80
        Tick Block Common Exploits
        Tick Websockets Support
        Access List - Publicly Accessible
    Custom locations tab
        Add the following locations
            location 1
                location - /notifications/hub
                Scheme - http
                Forward Hostname/IP - vaultwarden
                Forward Port - 3012
                Click the cog symbol and add the following to the textbox that appears
                    proxy_set_header Upgrade $http_upgrade;
                    proxy_set_header Connection "upgrade";
                    proxy_set_header X-Real-IP $remote_addr;

                    proxy_set_header X-Forwarded-Proto $scheme;
            location 3
                location - /

                    proxy_set_header Host $host;
                    proxy_set_header X-Real-IP $remote_addr;
                    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                    proxy_set_header X-Forwarded-Proto $scheme;
    SSL tab

        tick Use a DNS Challenge (or just expose port 80 if you accept the risk)
        DNS Provider - Dynu (this is my dyndns provider)
        Credentials File Content - replace YOUR_DYNU_AUTH_TOKEN with the API key from https://www.dynu.com/en-US/ControlPanel/APICredentials
        Email Address for Let's Encrypt - your email
        Tick I Agree to the Let's Encrypt Terms of Service
Click Save
Vaultwarden should now be accessible via https://vault.your.domain

Can I send you a pm regarding my progress so far? I'm kind off stuck at configuring everything:/
