One ClusterIP Service per app (mediathekarr's carries both of its ports); no global `ingress.domain`. Ingress in two shapes that mix: one host per app (default, each app's host required), or one shared `ingress.host` with the apps as sub-paths (documented ingress exception below) |
|

| `garage` | Garage (S3-compatible object store) | **One** node, `replication_factor = 1` — a deliberate trade with its price named (Gitea #81): the volume layer underneath already replicates and encrypts, so Garage replication on top would be nine times the raw data across two layers that know nothing about each other. What that costs is that the factor applies to the **metadata** too, where a corrupted database is upstream-documented as "generally not recoverable" and a replicated volume replicates the corruption. Hence three settings that are mandatory rather than optional: `metadata_fsync = true` (**off** in Garage's defaults), the automatic metadata snapshots, and those snapshots on a **second PVC** — a file-system snapshot of a live metadata database is not a restore point, so the volume backup covers the blocks and not the index. The first PVC carries `metadata_dir` **and** `data_dir` as two subdirectories, because volume snapshots are atomic per volume: that is what keeps index and blocks consistent with each other. Two further properties shape the whole chart: the image is **`FROM scratch`** and contains exactly one file, `/garage` — no shell, so **exec probes are impossible here** and an init container would need a second image — and the RPC secret has to arrive as an **environment variable**, because `rpc_secret_file` rejects any file with a group bit set while the kubelet sets one (the reasoning sits at the value). Started with `garage server --single-node`, which creates the cluster layout in-process before any listener opens and is idempotent on the layout version, and with `--default-access-key`/`--default-bucket`, which **import** key and bucket from the 1Password item — so the vault is the source of truth instead of a copy of what the server generated. Readiness is the admin API's `/health`, liveness and startup deliberately are **not**: `/health` answers 503 until a layout exists, so a node waiting for one would be restarted forever |

# CI values for the garage install-test.
|
||||
#
|
||||
# WHY THIS CHART IS TESTED RATHER THAN EXCLUDED, and what the test is worth:
|
||||
# with garage.singleNode (the chart default) the server creates its own cluster
|
||||
# layout before it opens any listener, so the pod reaches Ready without an
|
||||
# operator. That is what makes an install-test possible here at all - without
|
||||
# the flag the readiness probe would honestly never go green (no layout, no
|
||||
# quorum, /health answers 503) and a green run would have required a probe that
|
||||
# lies.
|
||||
#
|
||||
# WHAT A GREEN RUN PROVES - the four measurement points the plan for Gitea #81
|
||||
# left open, three of which this closes on every PR:
|
||||
#
|
||||
# 1. Garage accepts metadata_dir and data_dir as two SUBDIRECTORIES OF ONE
|
||||
# PVC and creates them itself. The image is FROM scratch and has no mkdir,
|
||||
# so if the assumption were wrong the pod could not start at all.
|
||||
# 2. readOnlyRootFilesystem: true holds with no emptyDir anywhere - the
|
||||
# container writes only into the two volumes.
|
||||
# 3. The layout is really applied in-process and the admin API answers 200 on
|
||||
# /health afterwards: Ready is exactly that HTTP 200, so the rollout
|
||||
# status IS the assertion.
|
||||
# Plus the mechanical half: the Secret key names match what the StatefulSet
|
||||
# references, the rendered garage.toml PARSES AS GARAGE READS IT (it opens
|
||||
# LMDB, validates replication_factor against --single-node and refuses
|
||||
# malformed keys), the access key and the bucket are imported from the vault
|
||||
# fields, the resource quantities are valid, and the schema accepts a
|
||||
# realistic non-default values file.
|
||||
#
|
||||
# WHAT IT DOES NOT PROVE, and no install-test here could:
|
||||
# - that the metadata auto-snapshot really lands in metadata_snapshots_dir.
|
||||
# The first snapshot is taken after interval/2, and the shortest interval
|
||||
# that is not absurd is still minutes - longer than the run. A snapshot
|
||||
# interval of seconds would test the timer, not the thing.
|
||||
# - anything about Longhorn: the snapshot semantics the chart's whole storage
|
||||
# layout is built on are a property of the storage layer, and the runner
|
||||
# has local-path.

|
||||
that item on start. The vault is the source of truth and nothing has to be
|
||||
copied out of the server.
|
||||
{{- end }}
|
||||
|
||||
FIRST START
|
||||
{{ if $settings.singleNode }}
|
||||
Nothing to do by hand. The server created its own cluster layout before it
|
||||
opened any listener{{ if $settings.defaultAccessKey }}, imported the access key{{ end }}{{ if $settings.defaultBucket }} and created the bucket{{ end }}.
|
||||
Verify it, in this order - all commands need /garage as the command, because
|
||||
the image has no shell:
|
||||
|
||||
1. kubectl -n {{ .Release.Namespace }} rollout status statefulset/{{ .Release.Name }}-{{ .Chart.Name }}-sfs
|
||||
Ready means the admin API answered 200 on /health, which means a layout
|
||||
exists and the node has quorum. Not-Ready with a running container means
|
||||
the layout is missing - check the logs for "Created initial layout".
|
||||
|
||||
2. kubectl -n {{ .Release.Namespace }} exec {{ $pod }} -- /garage status
|
||||
One node, with a role (zone dc1, a capacity taken from the detected disk
|
||||
size). A node WITHOUT a role means no layout was applied.
|
||||
|
||||
3. kubectl -n {{ .Release.Namespace }} exec {{ $pod }} -- /garage layout show
|
||||
{{- if $settings.defaultBucket }}
|
||||
|
||||
4. kubectl -n {{ .Release.Namespace }} exec {{ $pod }} -- /garage bucket list
|
||||
kubectl -n {{ .Release.Namespace }} exec {{ $pod }} -- /garage bucket info <bucket>
|
||||
The bucket exists and the imported key has read/write/owner on it.
|
||||
{{- end }}
|
||||
|
||||
5. One write through the S3 API from a client pod, which is the only step
|
||||
that proves the endpoint rather than the process.
|
||||
{{ else }}
|
||||
garage.singleNode is false, so THIS RELEASE SERVES NOTHING YET and the pod
|
||||
will stay not-Ready until a layout exists - that is correct, not a defect: the
|
||||
readiness probe reports /health, and /health answers 503 while there is no
|
||||
layout. Apply one by hand, in this order:
|
||||
|
||||
1. kubectl -n {{ .Release.Namespace }} exec {{ $pod }} -- /garage status
|
||||
Note the node id and the current layout version (0 on a fresh install).
|
||||
|
||||
2. kubectl -n {{ .Release.Namespace }} exec {{ $pod }} -- \
|
||||
/garage layout assign -z dc1 -c <capacity> <node-id>
|
||||
The capacity is this node's usable size, roughly storage.data.amount
|
||||
({{ .Values.storage.data.amount }}). It takes BYTE suffixes B, KB, MB, GB, TB, PB - not
|
||||
Kubernetes' Gi/Mi, so write e.g. 10GB, not 10Gi.
|
||||
|
||||
3. kubectl -n {{ .Release.Namespace }} exec {{ $pod }} -- /garage layout show
|
||||
Read it before applying. The next step is NOT reversible by repeating it.
|
||||
|
||||
4. kubectl -n {{ .Release.Namespace }} exec {{ $pod }} -- /garage layout apply --version <N+1>
|
||||
N is the version from step 1, so a fresh cluster takes --version 1.
|
||||
NEVER call this twice with the same --version: the flag is a guard
|
||||
against applying a staged change you have not seen, and reusing a number
|
||||
is how a layout is applied twice.
|
||||
|
||||
5. kubectl -n {{ .Release.Namespace }} exec {{ $pod }} -- /garage bucket create <bucket>
|
||||
kubectl -n {{ .Release.Namespace }} exec {{ $pod }} -- \
|
||||
/garage key import --yes <access-key> <secret-key>
|
||||
kubectl -n {{ .Release.Namespace }} exec {{ $pod }} -- \
|
||||
/garage bucket allow --read --write --owner --key <access-key> <bucket>
|
||||
|
||||
"key import" rather than "key create", so the credential still comes FROM
|
||||
the vault item. "key create" generates one and then it has to travel the
|
||||
other way, through a terminal, with the vault as a copy.
|
||||
|
||||
6. The pod becomes Ready within one probe period after step 4.

|
||||
WHAT THIS CHART DOES NOT RENDER, AND WHAT IS MISSING WITHOUT IT
|
||||
|
||||
- THE LONGHORN BACKUP LABELS. recurring-job.longhorn.io/daily-snapshot and
|
||||
.../daily-backup belong to the consuming bundle, not to this chart. They do
|
||||
NOT apply automatically: without them the off-site half of the backup plan
|
||||
does not exist, it only looks like it does.
|
||||
- The namespace's volume-encryption secret, if the StorageClass is
|
||||
longhorn-encrypted-ns: it resolves
|
||||
${pvc.namespace}-pvc-encryption-secret, and without that entry the PVCs
|
||||
stay Pending.
|
||||
- No kubernetes_discovery CRD and no bootstrap peers: a single node has no
|
||||
members to find.
|
||||
|
||||
TRAPS WORTH KNOWING BEFORE YOU NEED THEM
|
||||
|
||||
- THE METADATA IS NOT IN YOUR VOLUME BACKUP in any usable form. A
|
||||
file-system snapshot of a live metadata database is not a restore point -
|
||||
taken during a write it is corrupt. What IS a restore point are Garage's
|
||||
own snapshots, on the second PVC, taken every {{ $settings.metadataAutoSnapshotInterval }}.
|
||||
- THE WINDOW IS SHORT: exactly TWO snapshots are kept, the first after half
|
||||
the interval and every later one after the interval times a random
|
||||
1.0-1.2. With metadata_auto_snapshot_interval = {{ $settings.metadataAutoSnapshotInterval }} the oldest
|
||||
recovery point is therefore between one and two and a half intervals old,
|
||||
never more. A corruption found later than that is older than every
|
||||
snapshot that still exists.
|
||||
- metadata_fsync is ON here and OFF in Garage's defaults. If you ever see it
|
||||
missing from garage.toml, that is a regression, not a cleanup.
|
||||
- replication_factor 1 applies to the METADATA as well. Upstream calls a
|

- ROTATING THE S3 SECRET IS NOT A RE-SAVE. Garage refuses to start when the
|
||||
access key already exists with a different secret ("is associated with a
|
||||
secret key different than the one given in GARAGE_DEFAULT_SECRET_KEY"). To
|
||||
rotate: either put a NEW access-key id into the item (the old key stays and
|
||||
can be deleted with "/garage key delete"), or delete the old key first and
|
||||
then update both fields.
|
||||
- A CHANGE INSIDE A VAULT ITEM RESTARTS NOTHING. Helm never sees it. After
|
||||
changing a field:
|
||||
kubectl -n {{ .Release.Namespace }} rollout restart statefulset/{{ .Release.Name }}-{{ .Chart.Name }}-sfs
|
||||
(Repointing a secrets.*SecretRef at a different item DOES roll the pod -
|
||||
that is covered by checksum/secret-ref.)
|
||||
- THE IMAGE HAS NO SHELL. "kubectl exec -it ... -- sh" does not work and
|
||||
never will; every command above uses /garage directly. Exec probes are
|
||||
impossible in this chart for the same reason.
|
||||
- THE RPC SECRET IS IN THE PROCESS ENVIRONMENT, not in a file. That is
|
||||
forced, not chosen: Garage rejects a secret file with any group bit set,
|
||||
and the kubelet sets one. values.yaml has the mechanism.

THE EFFECTIVE GARAGE SETTINGS - everything the ConfigMap and the StatefulSet

read out of .Values.garage, merged onto this chart's defaults.

Why the whole settings block goes through the null-safe helper and not only the

three usual suspects (guideline 12.2: "the rule is about the shape, not about

those three block kinds"): every value below is dereferenced by a template, and

an erased one would not abort the render - it would render a garage.toml with

an empty right-hand side, or a containerPort with no number. The first produces

a pod that crash-loops on a config parse error, the second a manifest the API

server rejects at apply time. Both are failures that arrive after the render

looked fine, which is exactly the class #99 is about. Satisfactory shipped the

same shape with half its blocks null-safe and half not (Gitea #16), and the
|
||||
half that was not took the Service's port with it.

question a readiness probe asks, namely "can this node serve requests".

Measured against the source at tag v2.4.1 rather than chosen:
|

|
||||
- the S3 API server is spawned independently of the layout state
|
||||
(src/garage/server.rs, the S3/web/admin servers are all spawned after
|
||||
initial_config), so the S3 socket binds and ANSWERS - with errors - before
|

any layout exists. A tcpSocket probe on port 3900 would therefore report a
|
||||
service ready that accepts nothing, which is the lie this chart is not
|
||||
allowed to tell.
|
||||
- /health needs no token (@special in src/api/admin/router_v2.rs) and maps
|
||||
ClusterHealthStatus straight onto the status code: Healthy and Degraded ->
|
||||
200, Unavailable -> 503 with "Quorum is not available for some/all

partitions, reads and writes will fail". An unconfigured layout is a
|
||||
special case in src/rpc/system.rs and yields Unavailable.
|

|

So with garage.singleNode: true the pod becomes Ready a moment after start
|
||||
(initial_config applies the layout BEFORE the servers are spawned), and with
|
||||
singleNode: false it stays not-Ready until an operator applies a layout by hand

- which is the truth, not a defect: until then the S3 endpoint accepts nothing

sizing convenience (Gitea #81):

subdirectories of this one volume

2. <release>-garage-snapshots-pvc metadata_snapshots_dir

Claim 1 keeps index and blocks on ONE volume because Longhorn snapshots are

atomic per volume and never across volumes. Split over two volumes, a backup
|

can capture metadata that points at objects whose blocks were not written yet -

for a mail store exactly the failure "the mailbox lists a message whose body is

Claim 2 exists because Garage's own metadata snapshots are the only consistent
|

recovery point here (file-system snapshots of a live metadata database are not
|
||||
one), and a recovery point stored on the volume whose corruption it should
|
||||
repair is not a recovery point.

Both blocks are DELIBERATELY NOT null-safe: an erased size yields an invalid

PVC that is rejected at apply time, which is loud. A chart-side fallback would

silently size somebody's object store - and on an existing release it could not

# Garage - an S3-compatible object store, deployed as a SINGLE NODE.
|
||||
#
|
||||
# READ THIS FIRST, because it is the premise every value below rests on
|
||||
# (Gitea #81): this chart deploys ONE Garage node with replication_factor = 1,
|
||||
# on the assumption that the volume layer underneath it is replicated and
|
||||
# encrypted (longhorn-encrypted-ns in this cluster). Garage replication on top
|
||||
# of that would be three times the raw data again, from two layers that know
|
||||
# nothing about each other.
|
||||
#
|
||||
# WHAT THAT TRADE REALLY COSTS - named here because the chart cannot fix it:
|
||||
# upstream says of replication_factor = 1 "Do not use this for anything else
|
||||
# than test deployments", and the reason is that THE SAME FACTOR APPLIES TO THE
|
||||
# METADATA. A corrupted metadata database is, in upstream's words, "generally
|
||||
# not recoverable", and Longhorn does not help: it replicates the corrupted
|
||||
# file three times. Redundancy against device failure, yes; against file
|
||||
# corruption, no. What does help is the set of settings below -
|
||||
# metadata_fsync, the automatic metadata snapshots, and those snapshots living
|
||||
# on a second volume - and none of them is optional in this chart.
|
||||
#
|
||||
# THE IMAGE IS "FROM scratch" AND CONTAINS EXACTLY ONE FILE, /garage. No shell,
|
||||
# no coreutils, no package manager. Three consequences that come up every time
|
||||
# someone changes this chart:
|
||||
# - exec probes are impossible here, for good. All three probes are HTTP or
|
||||
# TCP (see the probe blocks below).
|
||||
# - an init container would need a SECOND image to pin, track and update.
|
||||
# Nothing needs one: Garage creates its own directories on start.
|
||||
# - "kubectl exec" works, but only with /garage as the command and without a
|
||||
# shell: kubectl exec <pod> -- /garage status
|
||||
|
||||
# Scale the whole chart down without uninstalling it: scaleDown: true renders
|
||||
# the StatefulSet with replicas: 0 and takes precedence over garage.replicas.
|
||||
# PVCs, Secrets, the Service and the Ingress stay in place; scaleDown: false
|
||||
# brings the workload back up.
|
||||
scaleDown: false
|
||||

||||
secrets:
|
||||
# op:// path of the 1Password item carrying the field "rpc-secret": 32 bytes
|
||||
# of random hex, i.e. "openssl rand -hex 32". REQUIRED - Garage uses it as
|
||||
# the network key of its RPC layer and refuses to start without it, single
|
||||
# node or not.
|
||||
#
|
||||
# IT ARRIVES AS AN ENVIRONMENT VARIABLE (GARAGE_RPC_SECRET), NOT AS A FILE,
|
||||
# and that is the one place where this chart departs from how valkey does it.
|
||||
# valkey argues explicitly for the file form - the password never appears in
|
||||
# the process environment - and that argument is right in general. It cannot
|
||||
# be followed here, and not because the file form would be inconvenient:
|
||||
# IT IS STRUCTURALLY IMPOSSIBLE in a non-root pod.
|
||||
#
|
||||
# - Garage's rpc_secret_file rejects any file whose mode has a group OR
|
||||
# other bit set: "if metadata.mode() & 0o077 != 0" in
|
||||
# src/garage/secrets.rs (v2.4.1, line 144). The error message says
|
||||
# "world-readable", but the mask tests the group bits as well.
|
||||
# - The kubelet OR-s the group-read bit onto every file of a secret volume
|
||||
# as soon as fsGroup is set: pkg/volume/volume_linux.go,
|
||||
# changeFilePermission does Chmod(info.Mode() | 0440) for a read-only
|
||||
# volume. So with fsGroup, Garage refuses to start.
|
||||
# - Without fsGroup the file stays owned by root, and our uid 20000 cannot
|
||||
# read it at all.
|
||||
# - Kubernetes can set the GROUP of such a file, never its OWNER. There is
|
||||
# no combination that satisfies both checks.
|
||||
#
|
||||
# The two ways around it were weighed and rejected (see Gitea #81):
|
||||
# allow_world_readable_secrets = true would switch the permission check off
|
||||
# for ALL of Garage's secret files, including ones nobody has set yet; and an
|
||||
# init container copying the file with mode 0600 would need a second image
|
||||
# for a scratch-based chart. What stays is the environment variable, which is
|
||||
# also the dominant pattern in this repo (paperless-ngx, stalwart).
|
||||
#
|
||||
# The residual price, stated rather than hidden: the secret is in the
|
||||
# container's process environment, so anyone who can exec into the pod or
|
||||
# read its /proc can see it. Garage itself declares the variable with
|
||||
# hide_env_values, so it does not print it in its own output.
|
||||
#
|
||||
# DO NOT "FIX" THIS BACK TO rpc_secret_file. The pod stops starting, and the

# file mode nobody can change from inside Kubernetes.

# the question a readiness probe asks.
|

#
|

# MEASURED AGAINST THE SOURCE AT v2.4.1, NOT CHOSEN: the S3 API server is
|
||||
# spawned independently of the layout state, so the S3 socket binds and
|
||||
# answers - with errors - before any layout exists. A tcpSocket probe on 3900
|
||||
# would therefore report a service ready that accepts nothing. /health needs
|
||||
# no token and maps the cluster health straight onto the status code: 200 for
|

# Healthy and Degraded, 503 for Unavailable, and an unconfigured layout is a
|

# special case that yields Unavailable.

# So with singleNode: true the pod becomes Ready a moment after start, and

# with singleNode: false it stays not-Ready until a layout is applied by
