Use when creating, managing, or debugging Helm charts, writing Chart.yaml or values.yaml files, templating K8s manifests with Go templates, managing Helm releases (install, upgrade, rollback), working with Helm repositories, creating chart libraries, or troubleshooting Helm deployment issues. Covers chart structure, values overrides, hooks, tests, dependencies, and OCI registry usage.

Create a feature branch following the git flow branching model, commit staged or unstaged changes with a well-crafted commit message, and open a GitHub Pull Request with a meaningful title, description, and assignee. Follows git flow conventions — branches are created from and merged back into `develop`, with `feature/`, `hotfix/`, `release/`, and `bugfix/` prefixes. Use this skill whenever the user wants to commit their work and raise a PR, says things like "commit and open a PR", "create a pull request for my changes", "push this to a branch", "ship this", "submit this for review", or any variation of wanting to save work and create a GitHub PR. Always use this skill even if the user only mentions one part (e.g. "just commit this") — the full branch-commit-PR flow is the default behavior.
ALWAYS use this skill when the user asks to create, draw, design, produce, or generate any visual asset that is not a photograph or illustration. Fires on words like diagram, chart, graph, flowchart, architecture, system map, topology, sequence diagram, state machine, class diagram, ER diagram, C4, UML, BPMN, mind map, org chart, wireframe, mockup, UI sketch, infographic, dashboard, treemap, sankey, heatmap, choropleth, network graph, map, plot, visualization, mermaid, d3, drawio, draw.io, .drawio, or any request to "visualize", "render", "show as a diagram", or produce .drawio / .png / .svg / .pdf architecture artifacts. Fires on domain phrasings like "AWS architecture", "Kubernetes namespaces", "microservices diagram", "identity/auth flow", "repo topology", "dev environment", "system context", "data flow", "pipeline diagram", "network topology", "P&ID", "wiring diagram". Routes to Mermaid for text-based docs diagrams, D3.js for data-driven charts/maps, and Draw.io for architecture/vendor-icon/editable deliv

Push and pull charts via OCI
helm registry login gcr.io -u _json_key --password-stdin < key.json
helm package ./chart
helm push my-app-1.2.0.tgz oci://gcr.io/my-project/charts
helm pull oci://gcr.io/my-project/charts/my-app --version 1.2.0
helm install my-release oci://gcr.io/my-project/charts/my-app --version 1.2.0
Library Charts
Creating a library chart
apiVersion: v2
name: common-lib
type: library
version: 1.0 .0
{{- define "common-lib.deployment" - }}
apiVersion: apps/v1
kind: Deployment
metadata:
name: {{ include "common-lib.fullname" . }}
labels:
{{- include "common-lib.labels" . | nindent 4 }}
spec:
replicas: {{ .Values.replicaCount }}
selector:
matchLabels:
{{- include "common-lib.selectorLabels" . | nindent 6 }}
template:
metadata:
labels:
{{- include "common-lib.selectorLabels" . | nindent 8 }}
spec:
containers:
- name: {{ .Chart.Name }}
image: "{{ .Values.image.repository }} :{{ .Values.image.tag }} "
resources:
{{- toYaml .Values.resources | nindent 12 }}
{{- end }}
Using a library chart
dependencies:
- name: common-lib
version: "1.0.0"
repository: "file://../common-lib"
{{- include "common-lib.deployment" . }}
Release Management
Inspect releases
helm history my-release -n namespace
helm get values my-release -n namespace
helm get values my-release -n namespace -a
helm get manifest my-release -n namespace
helm get notes my-release -n namespace
helm get all my-release -n namespace
Upgrade patterns
helm upgrade my-release ./chart -n namespace \
-f values.yaml \
--atomic \
--timeout 5m
helm upgrade --install my-release ./chart -n namespace -f values.yaml
helm upgrade my-release ./chart -n namespace -f values.yaml --dry-run
helm diff upgrade my-release ./chart -n namespace -f values.yaml
Rollback
helm rollback my-release -n namespace
helm rollback my-release 3 -n namespace
helm rollback my-release 3 -n namespace --wait --timeout 5m
Debugging
helm template my-release ./chart -f values.yaml
helm template my-release ./chart -f values.yaml --debug
helm install my-release ./chart -f values.yaml --dry-run --debug
helm lint ./chart
helm lint ./chart -f values.yaml
helm show values ./chart
helm show chart ./chart
helm show readme ./chart
Common issues Template rendering errors:
helm template my-release ./chart -s templates/deployment.yaml
helm template my-release ./chart | kubectl apply --dry-run=client -f -
Release stuck in pending/failed:
helm status my-release -n namespace
helm uninstall my-release -n namespace --no-hooks
kubectl delete secret -l owner=helm,name=my-release -n namespace
Best Practices
Use helm upgrade --install for idempotent deploymentsUse --atomic in CI/CD to auto-rollback failed upgradesPin chart versions in dependencies — avoid floating versionsUse values.schema.json to validate values before renderingInclude NOTES.txt with post-install instructionsUse named templates in _helpers.tpl — avoid duplication across templatesAdd checksum annotations for ConfigMaps/Secrets to trigger pod restart on config changesTest charts with helm lint, helm template, and helm testSeparate chart version from app version — bump chart version for chart changes, appVersion for application changesUse .helmignore to exclude CI files, tests, and docs from packaged chart
Package Requirements
helm >= 3.0 — Kubernetes package managerkubectl — for cluster access and validationOptional: helm-diff plugin — for previewing upgrade changes
