Fresh docker production install without SiteURL

I’m installing docker for production using this, but I’m doing in a internal LAN VM so I don’t have a SiteURL (skipping TLS and Gitlab)

Install Mattermost via Docker — Mattermost documentation

I plan to use caddy so I don’t need to expose the VM publicily. The docker install is fine , containers running fine but I can’t connect to web interface locally.

When I install using docker preview, that works so I presume there’s something missing for production steps?

Hi @overmat ,

the SiteURL does not depend on the installation being publicly available or on the fact if you’re using TLS or not. Its value should be exactly what your users will put into their clients and browsers then when they try to access your Mattermost installation, so if your Mattermost container is running on host on port 8065 but you want to proxy it through caddy and caddy is running on on port 80 and you do not use internal hostnames, your SiteURL should be set to

What error are you seeing when you try to access the web interface locally and what does local mean?

These are my install steps. Then I tried accessin from a webbrowser, no access. I see only ssh port 22 accessible.

Your nginx container is restarting all the time, I assume this is because you did not create the SSL certificates as mentioned in the documentation.

You will need to either manually provide the certificates or run the certbot container to generate them for you, otherwise you can use the without-nginx yaml file. The Mattermost application server’s port (8065) is not exposed to the host when the nginx container is also running.

oh I see. I reinstalled using the without ngnx, and it works! Thanks!.

Awesome, thanks for letting us know. Marking this topic as resolved now.
