 roshan | byteio.in 🌷 | this is my config https://yaso.su/UDwGxzpq | 03:54:42 |
| roshan | byteio.in 🌷 | i have open ports from Oracle Account for instance. | 03:55:10 |

| roshan | byteio.in 🌷 | Ports are also showing opened in Serial Console | 03:56:45 |
 Zhaofeng Li | Remove boot.isContainer = true; (it's not a container) and include oci-common.nix from this PR | 19:50:19 |
| Zhaofeng Li | But still from the serial console, can you try whether networking is working? Check ip , do some pings/traceroutes/etc | 19:51:16 |

| Linux Hackerman | I think this is an intentional breaking change on the Nix side | 12:39:38 |
| Linux Hackerman | oh right, this is only a problem with dirty trees though | 12:41:17 |
| Zhaofeng Li | Right, need to take a look. There are some more breaking changes regarding path: flakes that I noticed:

| Shyim | Hey,
How would you handle secrets? 🤔 | 09:01:57 |
| Linux Hackerman | Personally I have them checked into my deployment repo, encrypted with GPG, and use a little module to abstract over decrypting them | 09:02:55 |
| Linux Hackerman | https://gist.github.com/lheckemann/3f4f3ce05521f4ace32bddce0b66e189 | 09:03:16 |
 @v:meowy.tech | I use https://github.com/serokell/vault-secrets, but other popular options are sops-nix (https://github.com/Mic92/sops-nix) and git-crypt (https://github.com/AGWA/git-crypt) | 09:03:58 |
| Linux Hackerman | then for example I have
secrets.loki-password.user = "promtail";
services.promtail.configuration.clients = [ { ...; password_file = config.secrets.loki-password.path; } ];
| 09:04:34 |
| Linux Hackerman | and it decrypts the secret from secrets/$hostname/loki-password.gpg and copies it over at deployment time | 09:05:05 |
| Shyim | Linux Hackerman: So I need the private gpg key on the machine right? :D | 09:05:44 |
| Linux Hackerman | the advantage of this approach is that the secrets can theoretically not get copied to the nix store (in practice they do, because I use Flakes) | 09:05:53 |
| Linux Hackerman | Shyim: only on the machine from which you're deploying | 09:06:01 |
| Shyim | AHHH. cool | 09:06:43 |
| Linux Hackerman | but I think I'll be switching to agenix or sops-nix at some point in the future, partly because this approach is colmena-specific and I'm not sure I want to stick with colmena | 09:06:57 |
| Linux Hackerman | and partly because the secrets are persisted unencrypted on the target machines' disks, which I'd also prefer not to do | 09:07:26 |
| Shyim | I currently join ssh and just do nixos-rebuild so. tbh: I don't care if it's in nix store. I just don't want to have them on Github publicly accessible as my nix files are public :D | 09:08:14 |
| Linux Hackerman | both agenix and sops-nix copy the encrypted secrets to the store as part of the system closure, and they're encrypted to a key that lies on the machine (often the SSH host key) to be decrypted only to a ramfs at runtime | 09:08:37 |
| Linux Hackerman | then again, having both the encrypted secrets and the unencrypted SSH host key on disk isn't much different from having the unencrypted secrets on disk I guess | 09:09:27 |
| Linux Hackerman | the next-level thing would be to add a TPM and measured boot into the setup, but I'm nowhere near getting there lol | 09:10:05 |
