Imports the chart from cluster-config functionally unchanged, wires it into the publish/validate/install-test pipelines and publishes it as the first of three Java lines (0.4.0+upjava8). The only deviation from the source chart is the chart-global scaleDown flag plus a server.replicas value, following the satisfactory pattern: two of the three servers stand at 0 replicas in the cluster, which the chart could not express, and Fleet would otherwise start them on reconcile. The default (scaleDown: false) still renders replicas: 1, so the rendering of the running server is unchanged - verified byte-identical against the three real values files for all three Java lines. Known deficiencies (hardening, probes, naming scheme, hardcoded values, missing icon, the misleading mc-router auto-discovery annotations) are left untouched on purpose and are scheduled for stage 2.

Render the replica count for a Deployment/StatefulSet.

Input: dict
|
|
"scaleDown" the chart-global .Values.scaleDown flag (may be nil)
|
|
"replicas" the workload's replicas value (may be nil)
|
|
|
|
Rules (issue #25):
|
|
- scaleDown: true takes precedence and always yields 0.
|
|
- otherwise an explicitly set replicas value is used as given, including an
|
|
explicit 0 — Helm's "default" would swallow 0, hence the explicit
|
|
kindIs "invalid" nil check.
|
|
- a missing replicas value defaults to 1.
|
|
|
|
Usage (the values path to the workload's replicas varies per chart):
|
|
replicas: {{ include "minecraft-server.replicas" (dict "scaleDown" .Values.scaleDown "replicas" .Values.server.replicas) }}
|
|
|
|
NOTE: charts in this repo deliberately have no dependencies, so this helper is
|
|
duplicated into every chart's templates/_helpers.tpl with the chart's name as
|
|
define prefix. The reference implementation lives in template-chart.
|
|
|
|
This chart is a stage-1 import (issue #67) and does not yet follow the repo
|
|
conventions; only the replicas helper was taken over, because the scaleDown
|
|
flag is needed before the Fleet migration. The resources helper follows in
|
|
stage 2 together with the rest of the convention alignment.
