How to Provide Secure Access to Your Kubernetes Clusters Using an Overlay Network
- Overlay networks provide a solution for securing access to Kubernetes clusters without compromising protection.
- Fine-grained access helps reduce the attack surface and simplifies access for non-developers in staging and testing environments.
- Overlay networks like NetBird operate on top of existing network infrastructure, allowing secure peer-to-peer communication.
- NetBird facilitates specifying access based on machines, ports, geolocations, and operating systems.
- Deploying NetBird involves setting up the Kubernetes operator, creating configurations, and establishing secure connections to services.
- Configuring NetBird involves installing agents on machines, creating access policies, configuring nameservers, and testing connections.
- Using an overlay network like NetBird helps ensure secure access to internal services running in Kubernetes clusters without exposing them publicly.
- Managing access to Kubernetes clusters and services for different teams becomes easier with NetBird's group-based access control.
- NetBird and its Kubernetes operator are open-source, allowing users to explore and contribute to the project.
- Implementing an overlay network like NetBird is a recommended security best practice for clusters not requiring public access.
