Hi!

There seems to be something wrong with testing at the moment:

Thank you for reporting.

The build container tag we're using got deleted by an automatic cleanup tool. (Same issue as last week).
I've modified the regex being used, so hopefully this won't happen again.

I've kicked this pipeline off again and it looks to be working again now.

Kind regards, Chris

I spoke too soon.
Our "build" jobs are working fine.
Our "test" jobs are not. For some reason the "small" EC2 instances we spool up to run our testing jobs aren't being started, so our test jobs aren't being run. Grrr.
@Adler, Michael, please could you investigate?

Kind regards, Chris

Hi,

it looks like AWS has got some problems. From the logs:

"We currently do not have sufficient t3a.small capacity in the
Availability Zone you requested (eu-central-1a). Our system will be
working on provisioning additional capacity. You can currently get
t3a.small capacity by not specifying an Availability Zone in your
request or choosing eu-central-1b, eu-central-1c. Launching EC2
instance failed."

In general it seems like autoscaling has some issues in eu-central-1a
since I can also see i/o timeouts. I'll try to spin up a new cluster in
zone -1b.

Kind regards,
Michael

The new small cluster is up and running. Auto-scaling seems to work in
this zone.

The new cluster seems to be working.
I've paused the old "cip-project-small-v14" runners in GitLab.

Doh.
Do we need to consider adding some sort of fallback support to gitlab-cloud-ci so it'll try a different region if we get this kind of failure?

Thanks!

Hi Chris,

> failure?

yes, I've just implemented this. The small cluster will now (hopefully) try to
auto-scale across 3 different zones, thereby improving availability and
robustness. Previously we had a max node count of 5, now it's 6 (3
zones each having at most 2 nodes). Let's see how that works out in practice.
In particular I'm curious if the auto-scaler will choose a different zone if
it sees that a zone has reached its max count.
If we don't face any issues with that new strategy, then I will upgrade the
large cluster at some point in the future as well.

Kind Regards,
  Michael

Thank you.

Is there any relevant text we'll see in the GitLab CI job log to indicate which region is being used?
Or can this only be seen from AWS?

Sounds like a plan.

This can only be seen from AWS. We're using zones eu-central-1a,
eu-central-1b, eu-central-1c for the small cluster now.
