Apache Ranger Helm Chart

This Helm chart deploys Apache Ranger with a Bitnami PostgreSQL dependency on Kubernetes. It is designed for easy configuration, production readiness, and extensibility.

---

Features

• Deploys Apache Ranger Admin as a Kubernetes Deployment
• Bitnami PostgreSQL as a subchart for metadata storage
• Configurable resources, service types, and persistent storage
• Customizable admin password and database credentials
• ConfigMap-based configuration for install.properties
• Best practices for labels, naming, and maintainability
• Developer and project info displayed after install

---

Prerequisites

• Kubernetes 1.19+
• Helm 3.x
• PersistentVolume provisioner (for PostgreSQL persistence)
• (Optional) Ingress controller for external access

---

Configuration Files

• install.properties are generated as ConfigMaps and mounted into the Ranger container.
• Database and admin credentials are templated from values.yaml.

---

Accessing Ranger

• By default, the service is ClusterIP. For external access, set service.type to NodePort or LoadBalancer.
• Example (NodePort):
  • Set service.type: NodePort and service.nodePort: 30080
  • Access via http://<node-ip>:30080
• For quick testing, use port-forward:

  kubectl port-forward svc/apache-ranger-apache-ranger 6080:6080 -n ranger
  

  Then visit http://localhost:6080

---

Default Credentials

• Username: admin
• Password: as set in values.yaml (ranger.adminPassword)

---

Uninstalling

helm uninstall apache-ranger -n apache-ranger
