Running g1t yourself: the design, a docker compose proof, and a guide to what works today1// g1t's git store for self-hosting: plain bare repositories on disk.
2//
3// Hosted g1t keeps repositories in Cloudflare Artifacts. This server does
4// the same job with nothing but git: one bare repository per store key
5// under GITSTORE_ROOT, git's own smart HTTP (git http-backend) for clones,
6// fetches and pushes, and a small JSON API for the reads the repos service
7// makes (commits, trees, blobs, files) and for creating and forking.
8//
9// It is reached only by the Artifacts-compatible shim (workers/artifacts),
10// which the repos service is bound to in place of the Artifacts binding, and
11// by the repos service itself for git's smart HTTP. Nothing else should be
12// able to reach it: the API takes a shared secret, and git requests a
13// short-lived token the shim minted with the same secret.
14//
Repositories shard across git store namespaces, move between them, and can keep to the EU; a namespace can be served read-only from the self-hosted git store, rebuilt from the nightly backups (#20, #25)15// A key is a repository's name (`acme--rocket`), or a namespace and a name
16// (`g1t/acme--rocket`): hosted g1t's fallback store (docs/ARTIFACTS.md, R12)
17// keeps each Artifacts namespace's repositories in a directory of their
18// own, so a remote reads `<GITSTORE_URL>/git/<namespace>/<name>.git`, the
19// shape Artifacts gives remotes.
20//
21// GITSTORE_READ_ONLY=1 refuses everything that writes: pushes, creating,
22// forking, deleting, and minting write tokens. As a fallback the store
23// serves reads until told otherwise; the repos service refuses writes too.
24//
