KubeLB 1.4 has officially launched, and we are excited to share its release! This version introduces the most significant improvement to the operator experience yet: an entirely new web-based Dashboard. This update also brings robust support for air-gapped and offline deployments, and a set of multi-tenant security controls (Network Policies, Upstream TLS) that make it easier than ever to run KubeLB in regulated and restricted environments.
Release Highlights of KubeLB 1.4
KubeLB Dashboard
Until today, KubeLB’s power was available only through kubectl CLI and CRDs. KubeLB 1.4 changes that with a brand-new web Dashboard, purpose-built for day-2 operations across a multi-tenant fleet. Browse your tenants, LoadBalancers, Routes, WAF policies etc and get a detailed overview of health, traffic flow, and configuration without ever leaving the browser.
OIDC authentication plugs cleanly into any corporate identity provider, and an optional out-of-cluster kubeconfig lets you run the dashboard outside the management cluster if that fits your network model better. The edition is auto-detected at runtime, so no separate installations or manual handling are required.
Learn more at the KubeLB Dashboard repository and the KubeLB Dashboard documentation.
Air-Gap / Offline Deployment Support
Many of our enterprise users run KubeLB in regulated or sensitive environments where the management cluster has no direct internet access. KubeLB 1.4 makes air-gapped deployments a fully supported, first-class path. Every release now publishes the complete list of container images and Helm charts shipped by KubeLB, including bundled addons, as a release artifact. Customers can mirror that list into an internal registry once and scan it through their own supply chain.
All artifacts (container images and charts) are pinned to their specific SHA versions for security and immutability.
Learn more in the Air-Gap Installation.
Network Policies for Tenant Isolation
As KubeLB grows into the de-facto multi-tenant load balancer on Kubernetes, stronger tenant isolation has become a frequent ask from platform teams. For even harder tenant separation and to avoid issues like noisy neighbours; KubeLB now ships first-class Kubernetes NetworkPolicies for tenant isolation out of the box. Operators get safe defaults from day one, while still being able to enable, disable, or layer additional policies at both Global and Tenant level.
This works hand-in-hand with KubeLB’s existing namespace-per-tenant isolation model, giving you L3/L4 network-level guarantees to complement the API-level controls you already have.
