Kyverno Version Lookup

Query Kyverno Helm chart release information from Artifact Hub.

API Endpoint

https://artifacthub.io/api/v1/packages/helm/kyverno/kyverno

Quick Lookup

# Get all stable releases (no RCs) with dates
~/.claude/skills/kyverno-version-lookup/scripts/kyverno-versions.sh

# Get JSON for programmatic use
~/.claude/skills/kyverno-version-lookup/scripts/kyverno-versions.sh --json

# Get latest N releases
~/.claude/skills/kyverno-version-lookup/scripts/kyverno-versions.sh --limit 10

Manual API Query

# Fetch raw data
curl -s "https://artifacthub.io/api/v1/packages/helm/kyverno/kyverno" | jq '.available_versions'

# Filter stable releases only (no rc/beta/alpha)
curl -s "https://artifacthub.io/api/v1/packages/helm/kyverno/kyverno" | \
  jq '[.available_versions[] | select(.version | test("^[0-9]+\\.[0-9]+\\.[0-9]+quot;))]'

# Pretty table with dates
curl -s "https://artifacthub.io/api/v1/packages/helm/kyverno/kyverno" | \
  jq -r '[.available_versions[] | select(.version | test("^[0-9]+\\.[0-9]+\\.[0-9]+quot;))] |
         sort_by(.ts) | reverse |
         .[] | [.version, .app_version, (.ts | todate)] | @tsv' | \
  column -t -s #x27;\t'

Response Format

Each version entry contains:

Field	Description	Example
`version`	Helm chart version	`3.6.1`
`app_version`	Kyverno app version	`v1.16.1`
`ts`	Unix timestamp of release	`1764753174`
`contains_security_updates`	Security patch flag	`false`
`prerelease`	RC/beta/alpha flag	`false`

Version Mapping Reference

The Helm chart version and Kyverno app version follow different schemes:

Chart 3.x maps to Kyverno 1.1x (e.g., Chart 3.6.1 = Kyverno v1.16.1)
Chart 2.x maps to Kyverno 1.x (legacy)

Use Cases

Check latest stable version

curl -s "https://artifacthub.io/api/v1/packages/helm/kyverno/kyverno" | jq '.version, .app_version'

Find release date for specific version

curl -s "https://artifacthub.io/api/v1/packages/helm/kyverno/kyverno" | \
  jq '.available_versions[] | select(.version == "3.6.0") | .ts | todate'

List versions released in last 90 days

NINETY_DAYS_AGO=$(($(date +%s) - 7776000))
curl -s "https://artifacthub.io/api/v1/packages/helm/kyverno/kyverno" | \
  jq --argjson cutoff "$NINETY_DAYS_AGO" \
    '[.available_versions[] | select(.ts > $cutoff and (.version | test("^[0-9]+\\.[0-9]+\\.[0-9]+quot;)))]'

Self-Test

# Verify API is accessible and returns expected structure
curl -sf "https://artifacthub.io/api/v1/packages/helm/kyverno/kyverno" | \
  jq -e '.version and .app_version and .available_versions' > /dev/null && \
  echo "PASS: Kyverno version lookup working" || echo "FAIL: API check failed"
