No "Database type" options in UI

[estromenko]

After fresh installation in a local k3s cluster there are no options in "Database type" field, so the next steps are not available. All pods in everest-system, everest-monitoring, everest-olm and my target namespace are running. There are no errors in browser console.

Hello @estromenko! Thanks for mention of this issue!

I ran into the same problem in everest. In my case, the status of DBEngine data didn't come from BE to FE, which is why the ui showed exactly this picture.
The reason for this in my case turned out to be a forgotten wireguard connection that I had not disconnected in the background, which affected the work of the everest operator. The error wasn't visible in the console of my operating system where i worked with everest-cli, but I was able to find an entry about it in the tilt interface, with which I raised the local cluster at this path - http://localhost:port/r/everest-operator/overview.

@estromenko is your k8s cluster running behind a proxy blocking internet access?
The Everest operator requires access to Percona's Version Service (https://check.percona.com/) to figure out the available DB engine versions. If the operator can't reach the version service the UI will not know which engines (and versions) are available.

Hello everyone! Thanks a lot for the advises!
There were some issues with DNS resolution in my cluster. I noticed i/o timeout errors in coredns pod, so that's why everest couldn't reach https://check.percona.com address. I did 2 actions and I am not really sure which one solved the issue (might be both).

Steps to fix the issue:

1. Configure or reset iptables rules (for instance sudo iptables --flush).
2. Change nameserver in /etc/resolv.conf file and reinstall cluster. For example, I changed nameserver from 192.168.0.1 to 127.0.0.53 (might be bad advice because systemd-resolved resets this file, but it's out of the current topic).

What do you think about adding some UI error message in this case? It would help a lot in troubleshooting.
