Ring out the old, ring in the new, Ring, happy bells, across the snow: The year is going, let him go; Ring out the false, ring in the true. Ring out the grief that saps the mind, For those that here we see no more; Ring out the feud of rich and poor, Ring in redress to all mankind. Ring out a slowly dying cause, And ancient forms of party strife; Ring in the nobler modes of life, With sweeter manners, purer laws. Ring out the want, the care, the sin, The faithless coldness of the times; Ring out, ring out my mournful rhymes, But ring the fuller minstrel in. Ring out false pride in place and blood, The civic slander and the spite; Ring in the love of truth and right, Ring in the common love of good. Ring out old shapes of foul disease, Ring out the narrowing lust of gold; Ring out the thousand wars of old, Ring in the thousand years of peace. Ring in the valiant man and free, The larger heart, the kindlier hand; Ring out the darkness of the land, Ring in the Christ that is to be. — Alfred Tennyson From cf086dc3e86039a07915445aa66bb82aebf9db0a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nicolas=20=E2=80=9CNiols=E2=80=9D=20Jeannerod?= Date: Tue, 1 Oct 2024 13:07:09 +0200 Subject: [PATCH 2/2] Import vm02186's configuration as a flake --- flake.nix | 24 +++++ gitea-runner.nix | 41 ++++++++ hardware-configuration.nix | 37 +++++++ procolix-configuration.nix | 192 +++++++++++++++++++++++++++++++++++++ 4 files changed, 294 insertions(+) create mode 100644 flake.nix create mode 100644 gitea-runner.nix create mode 100644 hardware-configuration.nix create mode 100644 procolix-configuration.nix diff --git a/flake.nix b/flake.nix new file mode 100644 index 00000000..178f7f6e --- /dev/null +++ b/flake.nix @@ -0,0 +1,24 @@ +{ + inputs = { + nixpkgs.url = "github:nixos/nixpkgs/nixos-24.05"; + snf.url = "git+https://git.fediversity.eu/fediversity/simple-nixos-fediverse.git"; + }; + + outputs = { self, nixpkgs, snf }: + let + vmName = "vm02186"; + + in { + nixosConfigurations.${vmName} = nixpkgs.lib.nixosSystem { + system = "x86_64-linux"; + + modules = [ + ./procolix-configuration.nix + ./hardware-configuration.nix + ./gitea-runner.nix + ]; + }; + + isoInstallers.${vmName} = snf.mkInstaller nixpkgs self.nixosConfigurations.${vmName}; + }; +} diff --git a/gitea-runner.nix b/gitea-runner.nix new file mode 100644 index 00000000..ddfb335a --- /dev/null +++ b/gitea-runner.nix @@ -0,0 +1,41 @@ +{ pkgs, config, ... }: + +{ + services.gitea-actions-runner = { + package = pkgs.forgejo-actions-runner; + + instances.default = { + enable = true; + + name = config.networking.fqdn; + url = "https://git.fediversity.eu"; + token = "MKmFPY4nxfR4zPYHIRLoiJdrrfkGmcRymj0GWOAk"; + + settings = { + log.level = "info"; + runner = { + file = ".runner"; + capacity = 24; + timeout = "3h"; + insecure = false; + fetch_timeout = "5s"; + fetch_interval = "2s"; + }; + }; + + ## This runner supports Docker (with a default Ubuntu image) and native + ## modes.
