2021-12-12 r/3209 feat(ops/secrets): Make (encrypted) secrets part of the treeVincent Ambo1-1/+1
Currently in NixOS configuration using agenix secrets there is no build time validation of secret paths - things fail at runtime (system activation). To prevent that, this CL makes the secrets part of the tree based on the same configuration file used by agenix itself. This guards against: * agenix secrets.nix definition for a non-existent file * age.secrets value in a NixOS config for a non-existent secret Change-Id: I5b191dcbd5b2522566ff7c38f8a988bbf7679364

We already checked this in, but this commit adds the configuration for making use of it. There are two copies of besadii's JSON configuration with different permissions. Note that the buildkite-graphql-token path needs to be updated in static-pipeline.yml, but this needs to happen in a separate commit after deploy because the pipeline will break otherwise.

2021-12-10 r/3191 fix(ops/irccat): Avoid permissions issue with LoadCredentials=Vincent Ambo1-6/+1
The DynamicUser + Group configuration does not work as planned, thus the systemd LoadCredentials feature is used instead which makes the file (which itself is only readable by root) available in a memory-backed location only readable by the service. The secret is only available to `ExecStart` commands, so units using this feature can not be used with pre/post units and the like if those commands need secrets. To accommodate this, the merge of configuration files has been moved into the service launch script, which is now the ExecStart= process. For details take a look at https://www.freedesktop.org/software/systemd/man/systemd.exec.html#LoadCredential=ID:PATH Change-Id: I693fe5677cc0d63c7aa485c2c7472457c5262166

Since GCP nuked us, the backups are now moving to GleSYS' S3-compatible object storage. This refactors the restic module to support S3-compatible storage instead of GCP, and switches to the appropriate new secret paths. The secrets were placed on whitby manually and I verified that the backups work.

First step towards giving depot modules the ability to declare their own backup directories by moving all restic configuration into a new module and adding a NixOS option for inclusion/exclusion paths for backups. This still keeps all backup paths within the whitby config.

2021-09-16 r/2877 feat(git-serving): Configure josh to serve the depot over HTTPVincent Ambo1-14/+6
Previously we served the dumb git HTTP protocol from code.tvl.fyi via cgit. This CL disables this feature and instead runs josh in the same location (by redirecting appropriately), but while also enabling partial cloning of all subtrees of the depot. For example, after this CL the following would result in an independent clone of //nix/readTree: git clone https://code.tvl.fyi/depot.git:/nix/readTree.git Note that there are no josh workspaces configured at all for now, these references are only for static depot subpaths. Please refer to the documentation for josh for more information on available kinds of josh filters. Josh state is kept in a systemd state directory in /var/lib/josh and backed up to Restic. Backing this up is necessary, as josh uses stateful information to do things like tracking merges and rewriting history per subtree appropriately to avoid cloned repositories ending up in peculiar states.
