Logic's Kubernetes Helm Charts
A collection of opinionated Helm charts for Kubernetes application deployment, built around a shared
common library chart and routed through Istio. Infrastructure reference configs
(ArgoCD, Istio, observability) live alongside the charts in this repository.
Usage
Helm must be installed to use the charts. Please refer to Helm's documentation to get started.
Once Helm is set up properly, add the repository as follows:
helm repo add logic3579 https://logic3579.github.io/helm-charts
helm repo update
You can then run helm search repo logic3579 to see the charts.
Install a chart:
# Kafka UI
helm install my-kafka-ui logic3579/kafka-ui -f my-values.yaml
# Nightingale (n9e) monitoring system
helm install my-nightingale logic3579/nightingale -f my-values.yaml
Or install directly from an OCI registry — every release is mirrored to GHCR, Docker Hub, and Quay:
# GHCR (primary mirror)
helm install my-kafka-ui oci://ghcr.io/logic3579/helm-charts/kafka-ui --version 0.1.1
# Docker Hub
helm install my-kafka-ui oci://registry-1.docker.io/logic3579/kafka-ui --version 0.1.1
# Quay
helm install my-kafka-ui oci://quay.io/logic3579/kafka-ui --version 0.1.1
Uninstall a chart:
helm uninstall my-kafka-ui

Local Development
Resolve the common library dependency before linting or templating:
# Resolve common library dependency
helm dependency update charts/kafka-ui
# Lint (application charts only — common is a library and not linted standalone)
helm lint charts/kafka-ui
# Inspect rendered manifests
helm template my-release charts/kafka-ui -f charts/kafka-ui/values.yaml
Releasing a New Version
Publishing is fully automated via GitHub Actions. To release a new version:
- Modify chart source under
charts/ - Bump
versioninChart.yaml— this is the release trigger - Commit and push to
main
The workflow lints, packages, and publishes the new .tgz to the
gh-pages branch alongside a regenerated index.yaml. The repo retains
the latest 3 versions per chart. No Git tags, no GitHub Releases.
Contributing
The source code for all charts and infrastructure references lives on GitHub: https://github.com/logic3579/helm-charts. Issues and pull requests are welcome.
