Description

I followed "Installation with Docker" page: https://docs.gitea.io/en-us/install-with-docker/
My docker-compose.yml is attached: docker-compose.zip

The doco says "Visit http://server-ip:3000 and follow the installation wizard"

There was no installation wizard on this page though. Here is what I see:

When I click Explore link, I see a page that looks like a wizard start:

However when I click the Install button, it goes to the localhost:

Someone posted a suggestion which I can't see now, but it helped...

So it works now for me, thanks! Great tool.

So why it didn't kick-start, and I was very close to abandon it and switch to something else - it turned out that I needed to specify the correct address in a couple of fields:

I also noticed that sometimes this wizard starts as a first thing when I open URL for a freshly created container (I've made a few tests), but more often it doesn't and just shows the homepage (as I described above)

So I'd suggest the following:

1. The "Installation with Docker" page should mention that the Installation Wizard assumes "localhost:3000" for the end-user URL. I.e. if a specific IP and another port will be used - the user is expected to change the fields highlighted in the screenshot.
2. The Installation page need to be fixed - it's a bug that very often the home page is shown instead.
3. When (2) right above is fixed, then the Wizard should:
   3.1 Put those settings on top of the page, into a separate section to highlight it - because it's the most important settings for the docker installation, it wouldn't work until set to the proper values.
   3.2. The settings should not default to localhost:3000. It should suggest the location.host and location.port from the client side (using a bit of the client-side JavaScript), and never allow the whole service to run until the setting is specified & saved. It also should allow to change it easily from the web UI.
