Help with HOMEPAGE_ALLOWED_HOSTS

[parnic]

I am having a hard time determining exactly what this env var needs to be as Homepage is running in a docker container behind an nginx reverse proxy and I'm accessing it from a VPN. So the value could be one of probably 4 different options. It would save a lot of trial and error if the message told me where the current client was coming from so I could just set it to that.

My logs currently say to use an fqdn that I am accessing from, but using that isn't working. I am guessing this is an issue of reverse proxy setup, so maybe my nginx needs a new/different host instruction.

The error message does tell you exactly what you should set.

Sorry, my initial post could've been clearer. It does give a host to allow, but allowing that host still doesn't work.

I suspect there is a config issue, Im not sure exactly what, but 1.0.3 will allow disabling this if you prefer.

To check if it's set correctly, what is the output of env when run from inside the container? (or docker compose exec -it homepage env)

[parnic]

$ docker exec -it homepage env
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
HOSTNAME=::
TERM=xterm
NODE_VERSION=22.14.0
YARN_VERSION=1.22.22
NODE_ENV=production
PORT=3000
HOME=/root

Yea parnic, note that HOMEPAGE_ALLOWED_HOSTS isnt there. Take a look at how you are updating the container, etc. in portainer theres literally an ENV section, or under environment in compose. I forget if / how it might be different for stacks

Thanks for the info. I found the issue. I am running it from Komodo which sets the env when running the application, so it's not global to the container, but I apparently needed to edit my compose file as Komodo was setting env for the compose rather than the deployment.

btw homepage.local.apnalab.us:3550 is the FQDN, 192.168.4.56:3550 is the reverse proxy server, 192.168.5.10:3550 is the real IP of the server running my docker image

The documentation for this environment variable is bad/false.

When you read

This is a comma separated (no spaces) list of allowed hosts (sometimes with the port) that can access your homepage.

everybody understand , I need to specify the client ip (my workstation) .

But this is not the case. you need to put all the allowed fqdn or ip to reach your instance .
if you instance is under http://hp.toto.com, you need to put

HOMEPAGE_ALLOWED_HOSTS=hp.toto.com,or.any.other.fqdn

Please change your documentation

Fair enough, I made the wording clearer
