One Garage node with replication_factor = 1, built from template-chart to the style guide rather than copied from upstream's in-tree chart (Gitea #81). The single-node trade is deliberate and its price is named at the value: the factor applies to the metadata as well, where upstream calls a corrupted database "generally not recoverable" and a replicated volume replicates the corruption faithfully. The three countermeasures that work at factor 1 are therefore mandatory, not optional - metadata_fsync = true (off in Garage's defaults), the automatic metadata snapshots, and those snapshots on a second PVC. Storage: PVC 1 carries metadata_dir AND data_dir as two subdirectories, because volume snapshots are atomic per volume and that is what keeps index and blocks consistent with each other; PVC 2 carries metadata_snapshots_dir, because a recovery point must not die with the volume whose corruption it should repair. Garage creates all three directories itself, which matters because the image is FROM scratch and has no mkdir. Two corrections to the approved plan, both verified against the source at tag v2.4.1 and decided on the issue before implementation: - The RPC secret arrives as GARAGE_RPC_SECRET via secretKeyRef, not through rpc_secret_file. The file form cannot work in a non-root pod: read_secret_file rejects any mode with a group or other bit set (src/garage/secrets.rs:144, mask 0o077) while the kubelet OR-s the group-read bit onto every file of a secret volume once fsGroup is set (pkg/volume/volume_linux.go), and Kubernetes can set the group of such a file but never its owner. The mechanism is documented at the value so the next round does not "fix" it back. - The first start is done by the server, not by hand: garage server --single-node creates the layout in-process before any listener opens, is idempotent on the layout version and has no --version argument that could be reused, and --default-access-key/--default-bucket import key and bucket FROM the vault item. Both premises of the original "manual first start" decision fell with that. Probes follow from the same source reading: readiness is GET /health on the admin port, which answers 503 while no layout exists; liveness and startup are a TCP connect, because a probe that can only fail would restart a node waiting for its layout forever (same lesson as zipline, README 12.3). The S3 listener binds independently of the layout, so a TCP probe on 3900 would have been the lie the plan warned about. CI: fixtures under ci/garage/ rather than an exclusion - with --single-node the pod reaches Ready on its own, which makes the install-test an assertion about the layout, the one-PVC subdirectory layout and readOnlyRootFilesystem instead of a formality. The Renovate block carries a regex versioning anchored to ^v<major>.<minor>.<patch>$, because the registry receives 40-character commit-SHA tags almost daily (measured 2026-10-03: the newest 22 tags are all of that kind) and the four v1.99.x-internal builds sort above the v1.3.x line.

# freesailarr is deliberately absent: none of its ten images takes

# a Renovate PR, and its appVersion by hand.
