Caddy reverse-proxying Gitlab

Help
1

I’m trying to setup Gitlab on my ESXi server. I currently have it running with a default install on Ubuntu 18.04 at a LAN ip of 192.168.1.130. Gitlab currently works and is serving pages locally on http at http://192.168.1.130.

I’ve scoured the web looking for a successful setup to use Caddy to proxy a URL to https to Gitlab, but everything seems to want to run it locally (same server) or doesn’t want to pass through. With a basic caddyfile setup like this, it’s definitely not working (from the server with Caddy running, 192.168.1.20):

git.ESXISERVER.com {
  gzip
  proxy / 192.168.1.130 {
    transparent
  }
}

Any hints from people that may have been successful at doing this somehow?

Hi @ff4500, welcome to the Caddy community.

When you try your above setup, what goes wrong, exactly?

Currently not at my computer to throw the gitlab.rb file in here, but the external url in gitlab is set to http://192.168.1.130, per the Gitlab docs on it working with a reverse-proxy. It’s serving on port 80. It works just fine if you hit that URL.

In Caddy, I have the above config, but when you plug it into the url bar, it just fails. My other proxy forwards are working fine from the same file, so I know the caddyfile works.

Edit: There are no fails, no 40x or 50x messages, nothing in the log at all.

We will need a little more detail than this, I’m afraid. Without knowing where it fails, we’ll have no idea what to troubleshoot.

Does it timeout? Does Caddy respond with a 4xx or 5xx status? Do you get a certificate error? What do you see when it fails?

Yeah, sorry for being vague. I know better.

I’m not sure that the error was with Caddy at all, since I never saw any 40x or 50x headers. When I came back to it tonight, whatever I did before I left for dinner must have worked, and Gitlab started working.

For those that are curious, here’s my Caddyfile and gitlab.rb config files that are currently working:

caddyfile

git.THISISMYGITLABSERVER.xxx {
  gzip
  proxy / 192.168.1.xxx {
    transparent
  }
}

gitlab.rb (OMNIBUS install)

external_url 'http://192.168.1.xxx'
nginx['listen_port'] = 80
nginx['listen_https'] = false

It’s so simple, I’m surprised that it’s working. This is with a fresh install of Gitlab on Ubuntu 18.04 (running in a VM on ESXi) and an existing Caddy install (running in docker, on my gateway webserver, a Brix)

Thx for the moral support, and the flags for spam. Jeez.

Sorry for the inconvenience here. The system flagged you out for trying to post links to IP addresses. They just went into a queue for manual approval.

If you put them in code blocks, they don’t get flagged.

Glad to hear you’re up and running.

No problem. Just the end of a frustrating day of nothing working.
Thanks for manually approving them, and good to know for future use. My markdown is bad tonight too, I guess. Hahaha!
