Problem

The clickstack chart 3.0.0 ships appVersion: 2.27.0 but pins the
otel-collector image at tag: "2.19.0" in values.yaml. The 2.27.0
app pushes an OpAMP config to the collector containing a json: key in
the ClickHouse exporter, which the 2.19.0 binary rejects:

'clickhouseexporter.Config' has invalid keys: json

This causes an immediate CrashLoopBackOff on my-clickstack-otel-collector,
making port 4318 unavailable to any downstream collectors.

Related: #219

Changes

  • charts/clickstack/values.yaml: bump otel-collector.image.tag from 2.19.0 to 2.27.0 to match appVersion
  • .github/workflows/update-app-version.yml: add a step that updates the image tag in values.yaml alongside Chart.yaml on every future version bump, preventing this drift from recurring

The otel-collector image tag was hardcoded at 2.19.0 while the chart
appVersion is 2.27.0. The 2.27.0 app pushes an OpAMP config containing
a `json:` key in the ClickHouse exporter, which the 2.19.0 collector
binary rejects with:

  'clickhouseexporter.Config' has invalid keys: json

This causes an immediate CrashLoopBackOff on my-clickstack-otel-collector,
making port 4318 unavailable to any downstream collectors.

Fixes ClickHouse#219
