Multi tenant subdomains (Check it out to know how !)

[opestro]

Hi , i just started using coolify , i like it is so simple and has a lot of features. I want to ask about the wildcard domain for one app, i mean i have a multi tenant app like a saas so users can access the dashboard by their [id].domain.ltd for example , so the id is dynamic. I read the documents . You said that i need to enter the subdomain but what about the dynamic subdomain ?

@opestro any luck on this? I'm trying to figure out this as well :)

@benediktpannermayr , not sure about the letsencrypt part. There's no need to do anything on the proxy. Just copy the container labels shown above but make sure you're using the unique suffix. Hope this helps :)

Hi @mrvfino,
thank you for your quick and helpful answer.

Unfortunately I still dont't get any certificates assigned.

I'll take a closer look at this in the next few days.

Best regards

Hi @benediktpannermayr,

I have some update check. I did another deployment for a different application of mine that uses subdomains and I also encountered a certificate issue. Wherein only a default Traefik certificate is assigned to pages that use subdomains.

For some reason following this: https://coolify.io/docs/knowledge-base/traefik/wildcard-certificates helped. So I retract what I said about not doing anything with regards to the proxy.

The odd thing is that, I reverted my proxy configuration back and the certificate fix lingered, that's why I thought that it had nothing to do with wildcard subdomains (in https), but it actually does.

@mrvfino Do you set https://pricekodo.com as the "Wildcard Domain" for your server? In Servers -> localhost -> General -> "Wildcard Domain" input field

@yewyewXD hmmm I don't remember doing that. Just checked, that I actually didn't.

The key part for me was following the instruction for wildcard certs and updating my proxy configuration for the server.
