satisfactory: exponential-notation fix and NOTES.txt (6.1.0+upv1.9.10)

Teil von #157 und Teil von #43.

#157: multiplyQuantity turned a bare byte count into exponential notation.
The null-safe fallback helpers pass values through fromYaml, which parses
every number as float64, and Go's "%v" switches float64 to exponential
notation from about 1e6 upwards. A request of 1048576 became
"1.048576e+06" and the render aborted on the suffix check.

Both printf "%v" sites are replaced by the canonical satisfactory.formatNumber
helper: the input of multiplyQuantity and the output of a non-integer product.
The second one never reached the suffix check, so it did not abort - it
rendered a silently invalid quantity that only the API server would reject.

#43: adds templates/NOTES.txt. The chart has no Ingress and no secrets, so
the notes cover what an operator would otherwise read out of the templates:
the NodePort a player actually dials and the pinned-port collision between
two releases, the 20-minute Steam download budget and that SKIPUPDATE is
false on every start, what a green pod does and does not prove (no probe
ever touches the UDP game port), that saves and game files share one PVC on
a hardcoded longhorn class which helm uninstall deletes, the emptyDirs
counting against the ephemeral-storage limit, the deliberate limitFactor 2
and fsGroupChangePolicy OnRootMismatch, and that game.seasonalEvents is
passed through to DISABLESEASONALEVENTS uninverted.

No rendered Kubernetes object changes, so the bump is minor; appVersion
stays v1.9.10.

Satisfactory dedicated server {{ .Chart.AppVersion }} — release {{ .Release.Name }} in namespace {{ .Release.Namespace }}.
ACCESS — A NODEPORT, NOT A URL
This release has no Ingress, no certificate and no hostname. Players reach
the server by dialling a node of this cluster directly. In the game client:
Server Manager → Add Server →
<node-ip>:{{ $gamePort }}
The node addresses are not rendered here because the chart does not know
them:
kubectl get nodes -o wide
kubectl -n {{ .Release.Namespace }} get svc {{ $svc }}
The Service {{ $svc }}
publishes three ports, and every nodePort is PINNED to the same number as
the container port — so the port a player types is the port the server
believes it runs on:
{{ $gamePort }}/UDP game traffic — this is what the client actually plays over
{{ $gamePort }}/TCP the server's HTTPS API — also what the probes talk to
{{ $msgPort }}/TCP messaging port (server.messagingPort)
Only the game port goes into the client. Both must be reachable from the
outside; a firewall that forwards TCP but not UDP produces a server that
answers every health check and accepts no player.
Because the nodePorts are fixed rather than allocated, a SECOND release of
this chart in the same cluster collides with this one: the API server
rejects its Service with "provided port is already allocated" and that
release fails on the Service alone while the rest of it applies. Give a
second server its own server.gamePort and server.messagingPort.
{{- if $outOfRange }}
{{ $gamePort }}/{{ $msgPort }} ARE OUTSIDE THE DEFAULT NODE-PORT RANGE (30000-32767)
This install needs a cluster whose API server runs with an extended
--service-node-port-range; without it the Service is rejected and no one can
connect, while the StatefulSet still comes up green. The chart's defaults
(30777/30888) sit inside the range on purpose — they echo the game's usual
7777/8888 in the digits without needing a cluster-level change. Confirm the
Service actually exists before blaming the game:
kubectl -n {{ .Release.Namespace }} get svc {{ $svc }}
{{- end }}
{{ if eq $replicas "0" }}
SCALED TO ZERO
{{ if .Values.scaleDown }}scaleDown: true{{ else }}server.replicas: 0{{ end }} — the StatefulSet runs with replicas: 0, so the node port
above refuses every connection until you set it back and upgrade again. The
Service and the data volume {{ $pvc }}
stay in place, so no save is lost and the game files do not have to be
downloaded again.
{{ end }}
THE FIRST START DOWNLOADS THE GAME, AND IT IS NOT QUICK
The image does not carry the game. On start it fetches the server files
through Steam onto the volume, which is well over 10 GB. Until that is done
the pod is not Ready and the node port refuses connections — the endpoint
only joins the Service once readiness passes.
The startup probe is what protects this window{{ if $budget }} ({{ $budget }}){{ end }} and it holds
liveness and readiness off while it runs. If the download needs longer than
that budget, the kubelet kills the container; the next attempt continues
against whatever already lies on the volume, so a slow link can still
converge over several restarts — but it presents as CrashLoopBackOff, and
nothing in that word says "still downloading". Look at the log, not at the
restart count:
kubectl -n {{ .Release.Namespace }} logs -f {{ $pod }}
{{- if $skipUpdate }}
SKIPUPDATE IS OVERRIDDEN TO "{{ $skipRaw }}" IN YOUR env LIST
The chart itself pins SKIPUPDATE to "false", but your env entry repeats the
name and the later occurrence wins. Starts therefore skip the Steam update
check: restarts are fast, and the price is that a new game version is never
picked up while this override stands — including the one an app-version bump
of this chart expects. Remove it for one start after an upgrade.
{{- else }}
SKIPUPDATE is pinned to "false" by the chart and is not exposed as a value
(only an env entry repeating the name can override it). So this is not a
first-boot cost: EVERY start asks Steam for an update first, including every
restart and every helm upgrade. Plan a rollout as minutes of downtime, not
seconds.
{{- end }}
WHAT A GREEN POD PROVES — AND WHAT IT DOES NOT
Two of the three probes run the image's own /home/steam/healthcheck.sh,
which queries the server's HTTPS API on the game port; that is why they keep
working when server.gamePort is changed. Readiness is different: it is a
bare TCP connect on the "api" port and proves only that something accepts a
connection there.
So a Ready pod does mean the API answered at least once. What no probe in
this release ever touches is the UDP game port — the one the players
actually use. A node firewall, a NetworkPolicy or anything upstream that
forwards TCP only leaves all three probes green, the rollout green and the
restart count at zero, while not one client can join. That failure has to be
tested from outside the cluster; kubectl will never show it.
Note also that this chart runs a game server, and the install-test pipeline
skips it (ci/excluded-charts.txt: the image is multiple GB and Steam pulls
10 GB+ on first start). No CI job has ever started this workload — treat the
first rollout in a new cluster as the real test.
NO SECRETS — AND WHERE THE ADMIN PASSWORD ACTUALLY LIVES
This chart creates no OnePasswordItem, no Secret and no ConfigMap, and reads
none. There is nothing to prepare in 1Password for this release, and no
field-name mismatch that could bite you here.
The consequence is worth knowing: the server is claimed and its admin
password set from the game client on first connect, and that state lives in
the save data on the volume below — not in any Kubernetes object. Restoring
the volume restores the password with it; losing the volume loses it, and
nothing in this release can hand it back.
SAVE GAMES AND GAME FILES SHARE ONE VOLUME — AND uninstall DELETES IT
{{ $pvc }} ({{ $storage }}, storageClassName "longhorn")
is mounted twice from the SAME claim, on two subPaths:
config/ → /config saves and server settings
gameFiles/ → /config/gamefiles the Steam download
So server.storage has to hold both. The game files alone are north of 10 GB,
so a large part of the {{ $storage }} on this claim is spoken for before the first
save is written — and a volume that fills up during a Steam update fails the
update, not the save.
The storage class is hardcoded in the template and is NOT a value. On a
cluster without a "longhorn" class the claim stays Pending forever and the
pod never starts — with no error anywhere in the game server's log:
kubectl -n {{ .Release.Namespace }} get pvc {{ $pvc }}
This is an ordinary PVC belonging to the release, not a StatefulSet
volumeClaimTemplate: "helm uninstall {{ .Release.Name }}" deletes it, and under a
Delete reclaim policy every save goes with it. Back the volume up BEFORE
uninstalling — a helm.sh/resource-policy annotation added to the live PVC
afterwards does not save you, because Helm reads that annotation from the
release manifest, not from the cluster.
Growing server.storage only takes effect if the storage class allows volume
expansion. Shrinking it is refused by Kubernetes and makes the next
helm upgrade fail on the PVC instead of touching the data. (The claim is
named -vc, not -pvc: a documented exception, because renaming it would
provision a new empty volume and orphan the world.)
THE emptyDirs COUNT AGAINST THE EPHEMERAL-STORAGE LIMIT
The root filesystem is read-only, so /tmp and the steam user's ~/.steam,
~/.config and ~/.local are emptyDirs — steamcmd bootstraps itself into
~/.local/share/Steam. An emptyDir is ephemeral storage, and it counts
against this container's limit ({{ $eph }}).
An overrun does not fail as an error message: the kubelet evicts the whole
pod, and the reason sits on the pod, not in the server's log.
kubectl -n {{ .Release.Namespace }} describe pod {{ $pod }} | grep -A3 Evicted
Raise server.resources.requests.ephemeral-storage if you hit it; the limit
follows through server.resources.limitFactor.
RESOURCE LIMITS ARE COMPUTED FROM limitFactor ({{ $factor }})
Effective for this release:
requests memory {{ index $req "memory" | default "-" }} cpu {{ index $req "cpu" | default "-" }} ephemeral-storage {{ index $req "ephemeral-storage" | default "-" }}
limits memory {{ $mem }} ephemeral-storage {{ $eph }}
Memory and ephemeral-storage limits are not written anywhere — they are
computed as limitFactor x the request, so raising a request raises its limit
with it. An explicitly set limit always wins.
{{- if eq (printf "%v" $factor) "2" }}
The factor is deliberately 2 here and not the repo-wide 3: that is what
holds the memory limit at the 8Gi this chart has always published.
{{- else }}
You have moved the factor off this chart's default of 2 — which is the value
that held the memory limit at the 8Gi this chart has always published. At
{{ $factor }} the limit is {{ $mem }}. That is a legitimate choice, not a mistake, but it
is a deviation worth remembering when the pod is next OOMKilled or when a
node cannot fit it.
{{- end }}
No CPU limit is set at all unless you write one under
server.resources.limits.cpu. That is on purpose: CPU is compressible, so an
unlimited container gets throttled rather than killed — a memory limit can
end a session, a missing CPU limit only slows it down.
game.seasonalEvents IS PASSED THROUGH, NOT INVERTED
The chart hands game.seasonalEvents to the container as
DISABLESEASONALEVENTS unchanged. It is currently {{ $seasonalRaw }}, so the container
runs with DISABLESEASONALEVENTS={{ $seasonalRaw }} — seasonal events are {{ if $seasonalOff }}OFF{{ else }}ON{{ end }}.
{{ if $seasonalOff }}To turn them ON, set game.seasonalEvents: false.{{ else }}To turn them OFF, set game.seasonalEvents: true.{{ end }}
Read that twice: the value behaves as the opposite of what its name suggests
and of what values.schema.json claims. Believe this paragraph and the
rendered env var, not the key name.
THE USER ID IS PINNED, AND PUID/PGID DO NOTHING
The pod runs as 1000:1000 because the image supports rootless operation only
as its own "steam" user and its entrypoint rejects any other non-root
uid/gid. PUID and PGID are set to 1000 in the pod spec but only ever apply
to the image's ROOT entrypoint path, which this chart never takes — they are
inert here. Changing securityContext.pod.runAsUser is how you stop the
container from starting, not how you change the uid.
fsGroupChangePolicy is OnRootMismatch, also deliberate: it skips the
recursive chown of the multi-GB game files on every single pod start. The
price is worth knowing in advance — Kubernetes looks only at the volume's
TOP-LEVEL ownership. If that already reads 1000:1000, it does not descend,
so a subtree with wrong ownership (a restored backup, files written by
another uid) is never repaired and the server fails to write there. Fix such
a case by hand once; do not switch the policy to Always unless you want the
chown back on every start.
{{- if gt (atoi $replicas) 1 }}
MORE THAN ONE REPLICA WILL NOT WORK
server.replicas is {{ $replicas }}. Every pod of this StatefulSet mounts the same
ReadWriteOnce claim {{ $pvc }} at the same paths — there
is no volumeClaimTemplate — so the extra pods stay stuck before start unless
the storage class hands that claim to several nodes, and where they do start
they write the same save from two processes. The pinned nodePort makes the
point moot anyway: one port on a node routes to whichever pod is Ready. This
chart is built for exactly one replica.
{{- end }}
{{- if $beta }}
game.experimental IS ON — THE EXPERIMENTAL STEAM BRANCH
STEAMBETA=true, so the server is meant to run the experimental branch
instead of the stable one.
{{- if $skipUpdate }}
But SKIPUPDATE is overridden to "{{ $skipRaw }}" above, so no start fetches anything
from Steam — the branch switch does NOT take effect and the volume keeps
whatever build it already holds. These two settings contradict each other;
drop the SKIPUPDATE override for at least one start, or this flag does
nothing at all.
{{- else }}
Since SKIPUPDATE is false, that switch happens on the very next pod start,
not at some later opt-in.
{{- end }}
Back up /config before flipping this. A save opened by an experimental build
may not open on the stable build again, and setting game.experimental back
to false re-downloads the stable files but does not undo what happened to
the save.
{{- end }}
{{- if $debug }}
dev.debug IS ON
DEBUG=true, so the image logs verbosely. It changes what you read, not what
the server serves — but it makes the log noticeably larger, which matters
while the pod is downloading 10 GB and you are tailing it.
{{- end }}
{{- if .Values.env }}
env IS APPENDED, NOT MERGED
Your {{ len .Values.env }} entr{{ if eq (len .Values.env) 1 }}y lands{{ else }}ies land{{ end }} AFTER the nine variables the chart always sets
(DEBUG, MAXPLAYERS, PGID, PUID, SKIPUPDATE, STEAMBETA,
DISABLESEASONALEVENTS, SERVERGAMEPORT, SERVERMESSAGINGPORT) and are rendered
through tpl, so a value may contain template expressions.
A name repeated from that list is then present twice in the pod spec, and
Kubernetes keeps the last occurrence — which is the only way to override one
of them, SKIPUPDATE in particular. Verify what the container really got
rather than assuming:
kubectl -n {{ .Release.Namespace }} get statefulset {{ $sfs }} \
-o jsonpath='{.spec.template.spec.containers[0].env}'
Anything sensitive belongs in valueFrom.secretKeyRef. A plain "value" is
stored in the pod spec and readable by everyone who can read pods in
{{ .Release.Namespace }}.
