gitlab-ee on Ubuntu 18.04 gives unable to resolve host
Describe your question in as much detail as possible: I am unable to run Gitlab-EE on my machine.
-
What are you seeing, and how does it differ from what you expect to see? I am seeing “Hmm. We’re having trouble finding that site.” instead of the Gitlab welcome screen where I should be able to enter my root password for the first time.
wget http://gitlab.example.comgives errorunable to resolve host - Consider including screenshots, error messages, and/or other helpful visuals (some outputs attached below)
-
What version are you on (Hint:
/help) ? and are you using self-managed or gitlab.com? I don’t know how to find version number, but I installed gitlab on May 2, 2020 as per the instructions given at https://about.gitlab.com/install/#ubuntu (till step #3 only) - What troubleshooting steps have you already taken? Can you link to any docs or other resources so we know where you have been?
I have tried the advice at - https://docs.gitlab.com/omnibus/common_installation_problems/#gitlab-is-unreachable-in-my-browser but it didn’t help.
So I found this page - https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-gitlab-on-ubuntu-18-04
I was skimming the DO tutorial but was surprised that on doing step #3 I found that ufw was inactive immediately after ... apt install gitlab-ee. I activated it manually and again surprized that it had no rules. So I allowed http, https & OpenSSH.
If it matters, I’d like to inform that my postfix installation may be faulty I got error where dpkg was failing as $myhostname (used by postfix’s main.cf) was recorded incorrectly, for some mysterious reason ..name was being appended to $HOSTNAME and this improper recording made postfix installation fail.
I fixed the main.cf and moved on. Anyway, here are the outputs
