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

bash
# 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

bash
# 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]+$"))]'

# 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]+$"))] |
         sort_by(.ts) | reverse |
         .[] | [.version, .app_version, (.ts | todate)] | @tsv' | \
  column -t -s $'\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

  1. Check latest stable version

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

  2. Find release date for specific version

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

  3. List versions released in last 90 days

    bash
    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 > $cutoff and (.version | test("^[0-9]+\\.[0-9]+\\.[0-9]+$")))]'

Self-Test

bash
# 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"
