I’m trying to host a vaultwarden instance through docker and failing miserably. This isn’t my first attempt either but I’ve got much further than before.
I’m using a DuckDNS domain with caddy as reverse proxy, but it appears that the domain is defaulting to port 80 no matter how I set up the config. I can’t specify a port number in DuckDNS as far as I can tell. If the simple solution is to just buy a domain name I will consider it. Otherwise could really use some help in sorting out why it’s not connecting.
I can’t access Vaultwarden on the internal IP as it’s not being served as SSL but both Vaultwarden and Caddy are running with no errors in logs. I’ve left out a bunch of admin env variables for the Vaultwarden service to truncate the code.
docker-compose:
`[___](services:
vaultwarden:
container_name: vaultwarden
image: vaultwarden/server:latest
restart: unless-stopped
ports:
- 11808:80
- 11443:443
volumes:
- ./data/:/data/
environment:
- ROCKET_PORT=11444
caddy:
image: caddy:2
container_name: caddy2
restart: always
ports:
- 1808:11808
- 1443:11443
volumes:
- ./caddy:/usr/bin/caddy
- ./Caddyfile:/etc/caddy/Caddyfile:ro
- ./caddy-config:/config
- ./caddy-data:/data
environment:
DOMAIN: "https://example.duckdns.org/"
EMAIL: "example@domain.com"
DUCKDNS_TOKEN: "token"
LOG_FILE: "/data/access.log")`
Caddyfile:
’ {$DOMAIN}:1443 {
log {
level INFO
output file {$LOG_FILE} {
roll_size 10MB
roll_keep 10
}
}
tls {
dns duckdns {$DUCKDNS_TOKEN}
}
encode gzip
Notifications redirected to the WebSocket server
reverse_proxy /notifications/hub vaultwarden:3012
Proxy everything else to Rocket
reverse_proxy vaultwarden:11444
}`
Any idea where I’m going wrong?
I host Caddy and Vaultwarden using Docker. The traffic into the reverse proxy, Caddy, works over port 443, not 1808 or 1443. Using the Caddyfile, you can tell Caddy which port to send the traffic over.
Caddy docker-compose.yml
Caddyfile, although there are other ways to do this
*.example.com { @vaultwarden host vaultwarden.example.com handle @vaultwarden { reverse_proxy :11808 }
Vaultwarden docker-compose.yml
I think you can also use
services: vaultwarden: expose: - 80
And use 80 instead of 11808 in the caddy file.
Then the port will be available internally for caddy but not to the outside world. That may also need a network created in docker though. I’m on my phone so I can’t check the finer details at the moment.
