FAQPage Schema
How do I configure OAuth2-proxy authentication for a K3s cluster?▼

Configure OAuth2-proxy authentication for a K3s cluster by wiring oauth2-proxy behind Cloudflare Access to gate ingress and admin UIs. This setup enforces secure browser-based access to Kubernetes dashboards and services.

Can I use Cloudflare Access with ArgoCD and Open Web UI on Kubernetes?▼

Yes, you can use Cloudflare Access with ArgoCD and Open Web UI on Kubernetes. The integration enforces browser-based authentication for dashboards and apps by routing traffic through oauth2-proxy to gate ingress securely.

How does Dex integrate with oauth2-proxy for Kubernetes ingress?▼

Dex integrates with oauth2-proxy by providing identity federation for Kubernetes ingress. This combination validates authenticated sessions against the configured IdP, ensuring secure browser-based access to cluster services.

What are the considerations for MCP server exceptions when using oauth2-proxy?▼

Considerations for MCP server exceptions when using oauth2-proxy include managing token lifecycle and applying secure secret handling in Kubernetes environments. The configuration provides specific guidance for these exceptions to maintain security.

How do I handle 401 response headers and secure secrets for Kubernetes ingress?▼

Handle 401 response headers and secure secrets for Kubernetes ingress by enforcing correct 401 response headers and applying secure secret handling practices. This ensures safe credential management across cluster services.

Is oauth2-proxy the best way to gate access to Kubernetes dashboards behind Cloudflare?▼

Using oauth2-proxy is a scalable way to gate access to Kubernetes dashboards behind Cloudflare. It provides a dedicated authentication layer that integrates with Dex to avoid exposed credentials while securing browser-based access.
