@hexa:lossy.networkhexa and also things like enableACME on nginx 00:37:37

@hexa:lossy.networkhexa * #users:nixos.org is the room tbh 00:37:49
@m1cr0man:m1cr0man.comm1cr0man woobilicious: Ditto what hexa said - however you can DIY your own "disable all ACME" option. Just add a config option of your own (config.woobilicious.enableACME for example), then predicate your security.acme.certs and enableACME on that wherever you have it declared 18:55:38
@m1cr0man:m1cr0man.comm1cr0manI assume you're dealing with a test vm, is the root of this issue that ACME is looking for internet access to renew certs whilst testing your real system config? I personally don't know how to deal with that just for the test system, but IIRC there is some flag/marker that you are in a test vm?18:57:06

@woobilicious:matrix.orgwoobilicious m1cr0man:
Yeah I'm wanting to use nixos-rebuild test-vm, I used to use it before I hooked up ACME but I knew instantly it would cause issues, so I just started testing in production lol.
My real issue is that I still need certs for some of my config to work correctly. I guess I'll have to look in to profile system and how ACME works to have it generate certs but not try sign them.

@woobilicious:matrix.orgwoobiliciousI want to add anubis to my server, so it's going to be a whole ordeal getting the proxy setup and the certs working correctly.03:54:13

This might be overkill for your use case, but we set up an additional acme and name_server nodes that we can use to replace the real acme servers in tests

@soispha:vhack.euBenediktThe souce is here: https://git.foss-syndicate.org/vhack.eu/nixos-server/tree/tests/common/acme08:13:29
@woobilicious:matrix.orgwoobiliciousoh interesting, yeah might be a bit overkill, but maybe it'll be some good insperation.08:15:33
@woobilicious:matrix.orgwoobiliciousI could probably just disable the acme renewal service.08:17:33

That's nice. Seems to be based on the acme tests in nixpkgs?

Yes, initially I used the acme files directly, but had to vendor and significantly alter them to work as a drop in server (i.e. I did not understand how nixpkgs test acme stuff sets the CA root from pebble and they seemed to lack the dns server support)
14:58:10
@m1cr0man:m1cr0man.comm1cr0man I never considered this use case. I might look into making the test suite stuff reusable and having some form of support for nixos-ebuild build-vm 19:19:31

@emilazy:matrix.orgemilyWe have deleted the email addresses provided to Let’s Encrypt via the ACME API that were stored in our CA database in association with issuance data. This doesn’t affect addresses signed up to mailing lists and other systems. They are managed in a separate ISRG system unassociated with issuance data. Going forward, if an email address is provided to Let’s Encrypt via the ACME API, Let’s Encrypt will not store the address but will instead forward it to the general ISRG mailing list system unassociated with any account data. If the email address has not been seen before, that system may send an onboarding email with information about how to subscribe to various sources of updates. 12:49:54

@ctheune:matrix.flyingcircus.ioChristian Theune I'm working on a bit of a refactoring with Arian supervising. I've had a question this morning which I managed to solve with a draft so far. I'm still working on it, but the current state is here: https://github.com/NixOS/nixpkgs/pull/422076. The second commit is currently in draft and needs a further refactoring (and also has a race condition and is likely incomplete), but I have to stop working for today). If you want to take a look, feel free to give feedback. I'm also happy to explain/discuss things face to face if that helps understanding. It's a quite complicated situation and I'm trying to make it cleaner ... 14:48:16
