Doing this has two motivations: 1. Something like this would required if we want to support multiple runners configurations. Please note that this is already possible using NixOS containers. 2. Having an additional parent directory makes it easier to remap any of the directories. Without a parent, systemd is going to complain if, for example, the given StateDirectory= is a symlink. * nixos/github-runner: use specifier to get abs runtime path * nixos/github-runner: use hostname as default for option `name` Until now, the runner registration did not set the `--name` argument if the configuration option was `null`, the default for the option. According to GitHub's documentation, this instructs the registration script to use the machine's hostname. This commit causes the registration to always pass the `--name` argument to the runner configuration script. The option now defaults to `networking.hostName` which should be always set on NixOS. This change becomes necessary as the systemd service name includes the name of the runner since fcfa809 and, hence, expects it to be set. Thus, an unset `name` option leads to an error. * nixos/github-runner: use types.str for `name` option Forcing a `name` option to comply with a pattern which could also be used as a hostname is probably not required by GitHub. * nixos/github-runner: pass dir paths explicitly for ExecStartPre= * nixos/github-runner: update variable and script naming * nixos/github-runner: let systemd choose the user/group User and group naming restrictions are a complex topic [1] that I don't even want to touch. Let systemd figure out the username and group and reference it in our scripts through the USER environment variable. [1] https://systemd.io/USER_NAMES/ * Revert "nixos/github-runner: use types.str for `name` option" The escaping applied to the subdirectory paths given to StateDirectory=, RuntimeDirectory= and LogsDirectory= apparently doesn't use the same strategy that is used to escape unit names (cf. systemd-escape(1)). This makes it unreasonably hard to construct reliable paths which work for StateDirectory=/RuntimeDirectory=/LogsDirectory= and ExecStartPre=. Against this background, I decided to (re-)apply restrictions to the name a user might give for the GitHub runner. The pattern for `networking.hostName` seems like a reasonable choice, also as its value is the default if the `name` option isn't set. This reverts commit 193ac67ba3. * nixos/github-runner: use types.path for `tokenFile` option * nixos/github-runner: escape options used as shell arguments * nixos/github-runner: wait for network-online.target * github-runner: ignore additional online tests	2021-04-10 10:17:10 +00:00
