install gitlab self-managed without domain

I have an eks cluster and I would like to install gitlab self-managed with helm chart without using a purchased domain, is it possible to perform this installation without a domain or make a fake domain?

Thank you!

As far as I can tell, there is no officially documented way to run GitLab Helm Chart on EKS without using a domain.

You’ll need to use a domain for HTTPS, so if you plan to use GitLab in production at any level, I suggest obtaining a domain.

If you really want to run GitLab without a domain (for testing purposes), I suggest you consider running GitLab Omnibus on a Linux server.
With GitLab Omnibus, you can run a GitLab instance using only IP address

or use a dynamic DNS service DNS settings | GitLab.
