SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Upgrading Helm charts in production manifest repos is risky: skipped stepping-stone versions cause failed DB migrations, removed values keys break upgrades silently, and new charts may require newer Kubernetes versions than the cluster runs. This Skill provides a structured workflow to assess upgrade safety before touching a cluster. ## Core Features & Use Cases - Version Discovery: Finds the pinned chart version from README and values.yaml, then queries the upstream Helm repo for the latest available versions. - Impact Assessment: Diffs default values between current and target chart versions with helm show values, cross-references removed or renamed keys against your values.yaml, and checks Kubernetes version constraints. - Upgrade Path Validation: Detects mandatory stepping-stone versions from community forums, docs, and ArtifactHub changelogs to avoid DB migration failures. - Guided Execution: Runs the helm upgrade, watches pod rollout, triggers DB migrations via API when needed, and polls until the app reports UP. - Use Case: Ask whether SonarQube in your staging manifest repo can move from chart 2025.6.1 to 2026.4.0, and receive a full compatibility report plus a safe execution plan. ## Quick Start Ask the assistant to check if a newer chart version is available for a service in your manifest repo and whether it is safe to upgrade.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check if a Helm chart upgrade is safe before applying it?▼

Diff the default values between your current and target chart versions using helm show values, then cross-reference every key in your values.yaml against removed or renamed sections. Also verify upgrade path requirements and Kubernetes version minimums before running helm upgrade.

How to find the latest available version of a Helm chart?▼

Add the upstream chart repository with helm repo add, run helm repo update, then list versions with helm search repo <repo>/<chart> --versions. Compare against the pinned version recorded in your manifest repo README or values.yaml.

What happens if I skip a required stepping-stone version in a Helm upgrade?▼

Skipping mandated intermediate versions can cause database migration failures or data loss, as seen with projects like SonarQube. Check community forums, official upgrade path docs, and ArtifactHub changelogs; note the chart's default app version may already satisfy the stepping stone.

Does a Helm chart upgrade require changes to my values.yaml?▼

Not always. Many upgrades are values-compatible as-is; diff the chart default values first and only change keys that were removed or renamed. External database setups with subcharts disabled are typically unaffected by subchart removal.

Why does a Helm upgrade fail on an older Kubernetes cluster?▼

New chart versions often bump the minimum supported Kubernetes version, so a chart requiring 1.32 will not install on a 1.30 cluster. Check the chart metadata or ArtifactHub for supported versions and compare with kubectl get nodes output before upgrading.

How do I trigger a SonarQube database migration after a chart upgrade?▼

After the pod reports DB_MIGRATION_NEEDED via /api/system/status, trigger the migration with a POST to /api/system/migrate_db using kubectl exec, then poll the status endpoint until it returns UP. Using the API is faster and scriptable compared to the browser setup page.
