 ma27 | not sure if it's that easy, AFAIU you'd need a different owner for the git repo then (on production that's hydra-queue-runner vs hydra IIRC) | 12:08:42 |

| roberth | I might have caused that with a diverging nested attrset in nixos.tests.allDrivers, I think. I've fixed that problem in master at Jun 6 20:22:26 2022 +0200 | 07:30:13 |

Is there any more documentation about how to make Hydra build a Flake, beyond the comment on hydraJobs in https://nixos.wiki/wiki/Flakes ? | 07:54:53 |

I was told to re-ask my question here:
Is there any more documentation about how to make Hydra build a Flake, beyond the comment on hydraJobs in https://nixos.wiki/wiki/Flakes ? Hum, I'd say this is really all there is to it in a flake.nix. Or do you mean how to set up a flake project in the Hydra UI? | 08:02:57 |

how to set up a flake project in the Hydra UI?
This is the gap in my understanding. I can write flakes and I have set up a declarative jobset by writing a spec.json.

Ah, I think I did this by trial and error, too. I don't have a spec.json, and I don't think it's needed. Let me see if I can retrace my steps: | 08:05:43 |
| kenran_ |
- Create the project (give it a name and that's enough imho)
- Actions -> Create Jobset -> enter a flake URI, like
github:my/project. In my case (private GitLab instance) it's something like git+ssh://git@gitlab.foo.de/group/projectname?ref=main. Set some of the other preferences as you like.
jackdk is yours a private project too?
- If your Hydra has access to the repo then everything should be working soon thereafter, nothing more needed.

| 08:10:20 |
| jackdk | I'm thinking about how to do CI for my private/public projects because I feel a bit rude rebuilding the universe on various CI services, but I haven't actually got anything serious running. | 08:10:52 |
| kenran_ | (Mind you I'm also a first-time Hydra user, so there might be gaps in my understanding, but so far everything is working in my end.) | 08:10:58 |
| jackdk | But because the flake completely specifies its inputs, ISTM that you don't need the separate spec.json to declare which inputs you want in NIX_PATH or whatever | 08:11:53 |
| kenran_ | If you have private repos, then the hydra user on your server needs access via SSH. I've just added a special GitLab user and SSH key pair on the server in /var/lib/hydra (I think that was the path). | 08:12:35 |

But because the flake completely specifies its inputs, ISTM that you don't need the separate spec.json to declare which inputs you want in NIX_PATH or whatever Yeah, that sounds about right. I've never used spec.json; feels like hydraJobs make that obsolete for flake projects. | 08:13:16 |
| jackdk | Yeah it looks like spec.json does everything flakes do, but worse. Consider https://github.com/qfpl/reflex-workshop/blob/master/spec.json : it says "go evaluate release.nix from input reflex-workshop, setting <nixpkgs> and <reflex-workshop> in NIX_PATH. The attrset that the evaluation returns defines the jobs to actually run. | 08:16:50 |
| kenran_ | Ah yes. Just use the flake output type and enjoy :) | 08:17:27 |
| kenran_ | Sadly the NixOS tests I've written fail in my Hydra instance and I don't know why. I'll wait and see if anyone answers in the NixOS channel first, then re-post here in full detail. In essence all my tests use a postgresql service which after some time leads to
machine # [ 336.433468] postgresql-pre-start[896]: Success. You can now start the database server using:
machine # [ 336.452698] postgresql-pre-start[896]: /nix/store/6cn4h4icjjvg9yqx8iy55hvmqbq0jj2j-postgresql-10.21/bin/pg_ctl -D /var/lib/postgresql/10.0 -l logfile start
machine # [ 337.181043] systemd[1]: postgresql.service: Failed with result 'timeout'.
| 08:19:20 |
| kenran_ | Locally they're running just fine, so I'm at a loss. It's a flake project with everything pinned down and supposedly reproducible. | 08:19:46 |

| kenran_ | I'm trying to create a minimal example for my Hydra/PostgreSQL problem mentioned above now, mainly just using a postgresql_10 service and waiting for the unit to come up. This is what usually seems to fail on my Hydra, but not locally. | 10:31:10 |
| kenran_ | Hum, of course the minimal example works as expected. The only thing I can even think of is the pin. | 10:58:25 |
