Forward proxy setup

[den5o]

I have traefik running on a VPS listening on mydomain.tld and managing all certs. The VPS and a VM running on my home server are connected via NetBird. The VPS forward proxies all incoming requests to subdomain.mydomain.tld and *.subdomain.mydomain.tld to the VMs NetBird IP where NPM reverse proxies them to the correct service.

I have a few services running on the VM being served this way.

• Bookstack: books.subdomain.mydomain.tld
• SFTPgo: files.subdomain.mydomain.tld
• Baikal: baikal.subdomain.mydomain.tld
• Navidrome: music.subdomain.mydomain.tld

SFTPgo, Baikal, and Navidrome work without issue. Bookstack results in status code 500 strict-origin-when-cross-origin

As you can see in the compose file below I've included - APP_PROXIES=*. I also tried the VPS NetBird IP with the same result. I've also experimented with traefik headers with no success for a few days now. The config below does not include any of those as I've scrapped them.

I thought I'd post this issue here instead of traefik because I believe the APP_PROXIES environment variable should have taken care of this. Let me know if this would be more appropriate for traefik support.

@den5o It would be ideal to watch the actual app error log to understand what error is actually occurring.

I have not tested it, but I think for this kind of compose setup the logs could usually be read via:

docker compose exec bookstack tail -f /var/www/bookstack/storage/logs/laravel.log

Not sure about podman though.

@ssddanbrown thanks for the suggestion.

Here is the output of podman compose exec bookstack cat /var/www/bookstack/storage/logs/laravel.log.

[den5o]

Could it be my use of podman secrets that is causing those cipher errors?

The database env vars also use secrets and boostack establishes a connection to it.

echo $APP_KEY returns /run/secrets/bookstack_app-key and cat /run/secrets/bookstack_app-key returns the correct key. I tried using APP_KEY_FILE but that returns errors in the log and the container restarts.

[den5o]

I tried it without secrets and the log remains the same

[den5o]

So I got it working. I made a few mistakes in my compose. It should have worked the first time I tried it without secrets but I may have missed a step in resetting the config.

1. I didn't use _FILE at the end of MYSQL_ROOT_PASSWORD and MYSQL_PASSWORD so the passwords ended up being /run/secrets/bookstack_root_pass and /run/secrets/bookstack_db_pass respectively.
2. Because of 1, bookstack connected to the database because the password was set to /run/secrets/bookstack_db_pass
3. Because of 1 & 2 I assumed the bookstack image supported secrets.
4. APP_KEY was invalid as it was set to /run/secrets/bookstack_app_key

Is there any chance of adding support for secrets in the future?
