Description

Observation

The virt-install command failed to download kernel files from O3 repo sporadically: --location http://openqa.opensuse.org/assets/repo/openSUSE-Tumbleweed-oss-x86_64-CURRENT

the latest test hung at downloading initrd: https://openqa.opensuse.org/tests/3339451#step/unified_guest_installation/424

It appears that the http services in ariel do not function well at times. I don't know which web server is in use, nginx or apache2? I know little about the web services stuff, I only found some suspicious error logs on ariel. Could you please investigate if the http services are working well? and what's the cause of our test failure in downloading kernel files from O3 repo?

Acceptance criteria

  • AC1: No unexpected logs from multiple web servers e.g. not Apache and nginx at the same time
  • AC2: It is understood what routes are usable (http vs https)
  • AC3: openQA pulls in all necessary service dependencies on a web proxy but only really necessary ones
  • AC4: apache2 is not automatically restarted on o3 when nginx is already running

Suggestions

  • Maybe some script is restarting apache. unmask the service?
  • TLS is not provided by us (ha-proxy managed by heroes); but let's still clarify what is supposed to work?
  • Ask other admins on openSUSE channels about possibly running scripts that interfere and maybe start Apache2
  • Make apache2 and nginx exclusive or use a generic target in systemd or just drop it
  • Potentially mention in documentation that to prevent a conflict apache and nginx should not be installed together

I noticed that those URLs start with http://, that will trigger a redirect to https://. Maybe that is not handled correctly in the test?

Yes, that's the thing. I initially tried my command with "http://download.opensuse.org" and it took 3 minutes. while with "http://O3" it took 23 minutes. Finally I changed to use 'https://O3', it took 3 minutes too.

I will switch to 'https' in my test. thank you.

The virt-install command with "http://" I used. the output tells 23 minutes in total.

Is there any configuration required for accessing O3 with https from test side?

And I just accessed O3 repo by using virt-install with 'http' succefully and very fast. I am confused, why sometimes 'http' worked while 'https' did not work, and vice versa.

I think this is actually caused by dependencies in the openQA systemd unit files. Every new deployment of openQA triggers a service restart, which then tries to restart apache2. Probably those just need to be updated from apache2 to nginx.

Maybe that dependency can be generalized. If not then maybe the dependency can be reduced as there are multiple levels in systemd, I think. Like not definitely need apache/nginx but want to have something like apache or nginx but if not then fine as well :)

Removing estimate as likely we should reconsider and fix it properly accordingly.

    sudo systemctl reset-failed apache2

  1. Ensure Apache won't continue to show as "failed" (it doesn't seem like it should be doing anything currently consider Jun 16 13:53:17 ariel start_apache2[11260]: (98)Address already in use: AH00072: make_sock: could not bind to address [::]:80 according to the journal).
  2. Mask the service
  3. Apache's no longer pulled in as a dependency

So by testing it out I confirmed that "disabled" is not enough even for "wants", but masking seems to work fine. Most likely we don't want to change anything to our packaging/ services.

Looks like the masking is still effective. So there's no urgent problem on o3 anymore. So wouldn't it make more sense to continue working on the "blocked" ticket #131024. When that ticket has been resolved we can supposedly remove the masking and consider this ticket resolved as well. Otherwise I wouldn't know what's left to do here.

Well, the idea was to adapt or generalize any systemd dependencies where possible and necessary first. That's why I was convinced that this ticket should be worked on first. But if you feel that is the wrong way around feel welcome to pick up the other independently. I will update #131024 accordingly

I haven't found a generic service one could depend on. So I guess the easiest solution is to simply remove the dependency on systemd level (see https://github.com/os-autoinst/openQA/pull/5213). It is a breaking change for some setups (none of our production setups and likely not most setups in general) but I think we can live with that (better than over engineering a more complicated solution).

The PR has been merged and we haven't had to revert it yet. It will take a while until all our users will update. Likely it makes no sense to keep this ticket open for a month or so. So I'm resolving it right now and we can still re-open it later if necessary.
