Teil von #157 und Teil von #43. #157: multiplyQuantity turned its input into a string with printf "%v". The null-safe fallback helpers from #99 route values through fromYaml, which parses every number as float64, and Go switches float64 to exponential notation from about 1e6 upwards. A request of 1048576 therefore reached the suffix check as "1.048576e+06" and aborted the render. The second printf "%v", the one that prints a non-integer product, never reaches that check at all: with a fractional limitFactor it wrote an invalid quantity into the manifest without a word. Both sites now go through the canonical teamspeak-server.formatNumber helper, identical to the other charts. Note for this chart: values.schema.json types resources.limitFactor as "number", not "integer", so the silent path is reachable with ordinary values rather than only with --set-json. #43: adds templates/NOTES.txt. teamspeak-server is a NodePort service with no Ingress and no secrets at all, so the notes cover what is actually worth looking up. Measured against the pinned image 6.0.0-beta12.1 rather than taken from upstream docs: the first start prints a ServerAdmin privilege key and ServerQuery credentials exactly once, and only the privilege key is recoverable afterwards from the log files on the data volume; TSSERVER_ DEFAULT_PORT is read only when the virtual server is created, so changing server.voicePort on an existing release moves the Service, the nodePort and the containerPort while the server keeps answering on the old port, with all three probes staying green because they only ever TCP-connect to the file transfer port; TSSERVER_FILE_TRANSFER_PORT, by contrast, applies on every start; the bundled license runs 2026-07-01 to 2026-10-01 with one virtual server and 32 slots; and no query port listens at all, which leaves the declared web-query container port 10080 bound by nothing. Minor bump: additive, appVersion unchanged.

Render the body of a container "resources:" block from a values dict of the form

limitFactor: 3 # optional, default 3
|
|
requests: { cpu, memory, ephemeral-storage / ephemeralStorage, ... }
|
|
limits: { ... } # optional, every entry optional
|
|
|
|
Rules (variant B, see issue #19):
|
|
- requests are rendered as given (camelCase "ephemeralStorage" is normalized
|
|
to the Kubernetes key "ephemeral-storage").
|
|
- an explicitly set limit always wins.
|
|
- a missing memory / ephemeral-storage limit is computed as
|
|
limitFactor x the corresponding request.
|
|
- a missing cpu limit is NOT set at all (the kubelet then treats CPU as
|
|
unlimited; CPU is compressible, so this cannot kill the workload).
|
|
|
|
Usage (the values path to the resources dict varies per chart):
|
|
resources:

Merge a user-supplied values sub-tree onto a dict of chart defaults so that a
|
|
null / empty override falls back to the defaults instead of erasing them.
|
|
|
|
Input: dict "defaults" <dict> "given" <dict|nil> "path" <string, optional
|
|
values path used in error messages>. Output: YAML of the merged dict (consume
|
|
it with fromYaml).
|
|
|
|
Why this exists (issue #99): Helm merges values maps recursively, but an
|
|
override key written without children — e.g. a leftover
|
|
|
|
securityContext:
|
|
|
|
after deleting its last remaining sub-key — is YAML null. Where the chart
|
|
defines a default, Helm treats that null as a deletion of the default; the
|
|
template then renders "securityContext: null": no readOnlyRootFilesystem, no
|
|
dropped capabilities, no allowPrivilegeEscalation: false. The workload starts
|
|
and reports healthy while being unhardened, so nothing points at the mistake.
|
|
The same shape erases a probe (it disappears) or the resources block (no
|
|
requests, no computed limits). This helper defines the opposite semantics: an
|
|
empty block means "chart defaults apply".
|
|
|
|
Rules:
|
|
- a nil "given" is treated as an empty dict (all defaults apply).
|
|
- a key whose override value is null keeps the default (nulls never delete).
|
|
- a key present in both as a map is merged recursively, so a partially
|
|
filled block only overrides the keys it actually sets.
|
|
- a scalar override for a key the defaults define as a map is rejected with
|
|
a message naming the values path, instead of failing later with a template
|
|
field error.
|
|
- any other set value wins as given, including an explicit false or 0 —
|
|
Helm's "default" and sprig's "mergeOverwrite" would both swallow those
|
|
zero values, hence the explicit kindIs "invalid" nil check.
|
|
- keys only present in the override are passed through unchanged.
|
|
|
|
NOTE: like the helpers above, this is duplicated into every chart's

|
