GitOps Without Borders: Running Argo CD Across Isolated Security Domains with Rafay’s Zero-Trust Kubectl
Modern enterprises rarely run applications in a single cluster. A production fleet might include on-prem clusters in Singapore and London, a regulated environment in AWS us-east-1, and a developer sandbox in someone’s laptop. GitOps with Argo CD is the natural way to keep all those clusters in the desired state—but the moment clusters live in different security domains (fire-walled data centers, private VPCs, or even air-gapped networks) the simple argocd cluster add story breaks down:
- Bespoke bastion hosts or VPN tunnels for every hop
- Long-lived bearer-token Secrets stashed in Argo’s namespace
- High latency between the GitOps engine and far-flung clusters, turning reconciliations into a slog
Rafay’s Zero-Trust Kubectl Access (ZTKA) solves all three problems in one stroke. By front-loading the connection with a hardened Kube API Access Proxy—and issuing just-in-time (JIT), short-lived ServiceAccounts inside every cluster.
In this blog, we will describe how Rafay Zero Trust Kubectl Access Proxy gives Argo CD a secure path to every cluster in the fleet, even when those clusters sit deep behind corporate firewalls.
