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

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

2. 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'
   

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