Overview

The RAD Plugins Helm chart is a vital component of the RAD security platform, designed to enhance Kubernetes security through a suite of specialized plugins. RAD Security provides a streamlined management process for security plugins. You can perform a variety of actions to maintain and update your security posture within Kubernetes:
  • Install: Initialize your security infrastructure with custom configurations specific to your cluster needs
  • Upgrade: Keep security measures up-to-date with straightforward upgrade paths
  • Delete (Uninstall): Remove RAD plugins cleanly without leaving residual configurations
  • Verify: Ensure plugins are running correctly after any action

​
Prerequisites

Before installing RAD Security on your Kubernetes cluster, ensure you meet the following requirements:

​
System Requirements

  • Kubernetes Version: 1.20 or higher
  • Helm Version: v3.0 or higher
  • kubectl: Admin access to the cluster
  • Cert-manager: Must be installed for secure plugin communication

​
Cluster Access

  • RBAC Permissions: Cluster admin or equivalent permissions
  • Network Access: Outbound HTTPS access to RAD API servers
  • Storage: Persistent volume support for data storage

​
Resource Requirements

  • CPU: Minimum 2 cores per node for runtime monitoring
  • Memory: Minimum 4GB RAM per node
  • Storage: 10GB persistent storage for logs and data

​
Network Requirements

​
Outbound Connections

RAD Security requires outbound HTTPS connections to:
  • api.rad.security - Main API endpoint

​
Installation

Installation is straightforward with Helm, including setting up a values.yaml file with your specific configuration and verifying the installation with kubectl commands. For detailed installation steps, refer to the RAD artifact.io plugins page.
RAD Plugins: The RAD pods require outbound access to RAD API server, and the Helm chart should be kept up-to-date to ensure the latest security features and fixes are applied.

​
Security Considerations

  • RBAC: RAD Security creates minimal RBAC permissions
  • Network Policies: Compatible with Kubernetes Network Policies
  • Pod Security Standards: Follows restricted pod security standards
  • Image Security: All images are signed and scanned

​
Troubleshooting

​
Common Issues

  1. Cert-manager Missing: Install cert-manager before RAD Security
  2. Insufficient Permissions: Ensure cluster admin access
  3. Network Connectivity: Verify outbound HTTPS access
  4. Resource Constraints: Check CPU and memory limits
