Notable QKS Features

Kubernetes High Availability Configuration Using HAProxy and VIP Manager

Keepalived (VIP Manager) and Layer 4 (L4) HAProxy are deployed as static pods on each master node to ensure high availability (HA) for Kubernetes master nodes.
Keepalived monitors the status of each node and activates the virtual IP (VIP) on a healthy node. The L4 HAProxy load balancer routes client requests to the active VIP, ensuring continuous access.
If a node fails, Keepalived updates the VIP to another healthy node, and HAProxy redirects traffic to maintain uninterrupted service. This configuration ensures robust and reliable management of the Kubernetes cluster.

QKS Repository – Tailored for Air-gapped Environments

Based on extensive service experience in sensitive environments (Air-gapped) such as government agencies and financial institutions, we provide the QKS Repository, designed specifically for conditions without internet connectivity.
QUANTUM C&S possesses specialized expertise in installing and operating Kubernetes in offline environments. The process of gathering required packages, images, and Helm charts is fully automated using Ansible.
Users can leverage the QKS Repository even in offline environments to pull images using commands like 'docker pull'. This provides a seamless experience, as if connected to the internet.
