 gabyx | Any body has a similar setup with Gitlab Runners? | 15:13:03 |
 hexa (signing key rotation when) | that will end you up in docker | 15:26:26 |
| hexa (signing key rotation when) | don't think gitlab supports anything else | 15:26:32 |
| hexa (signing key rotation when) | but yeah, you can have autoscaling groups iirc | 15:26:52 |
| gabyx | Shell executors, but jeah you are right. | 15:26:55 |
| gabyx | How do you spawn nixos vms, whats the mechanics here, is it the GHA runner which can do that? Or what ingredients is needed to make that work? kubernetes no right> that would end you up in containers as well? | 15:28:47 |
 Arian | Listen to GitHub webhooks and then do ec2:RunInstances call | 17:29:58 |
| Arian | That spawns a nixos VM with gha runner | 17:30:24 |
 vcunat | self-hosted GitLab certainly allows to have other stuff, probably via the shell executor. We have LXC that way. | 18:38:36 |

| Arian | don't have access to my Yubikey atm to check. the AWS account Hand-waivy how many objects do we upload to the cache per month? Context: Was thinking of setting up an SNS topic of EventBridge bus to allow people to subscribe to upload events through webhooks e.g. for people who want to set up downstream caches and keep in sync with cache.nixos.org . Wanted to make a quick napkin calculation of the cost.

| Arian | monthly cost for EventBridge would be $11 . Then each webhook destination would cost $2 per month

| Arian | * monthly cost for EventBridge would be $11 as we publish ~11m objects per month . Then each webhook destination would cost $2 per month
cc flokli
| 23:26:43 |
| Arian | Probably slightly cheaper if if we only notify on narinfo files. This is peanuts. Very feasible | 23:27:09 |

| susd | The vesktop package doesn't build. The last build job was manually cancelled. https://hydra.nixos.org/build/318346439 | 10:07:11 |
| vcunat | nixpkgs evals more often, so it's better to watch packages in there:

| vcunat | BTW, the vesktop failure has 4 issues already in the past several hours:
https://github.com/NixOS/nixpkgs/issues?q=vesktop
(and apparently it's been solved) | 10:12:35 |

| susd | yeah my bad didn't check the closed issues | 10:13:19 |
| vcunat | I restarted the aborted duplicate job, too. Maybe it will help to decrease the chaos. | 10:13:49 |
