Ingress NGINX Controller

Overview

ingress-nginx is an Ingress controller for Kubernetes using NGINX as a reverse proxy and load balancer.

Learn more about Ingress on the main Kubernetes documentation site.

Get started

See the Getting Started document.

Troubleshooting

You can use the debug image to debug the ingress processes, you will have to expose a port (i.e 40000) in the deployment and from the pod run: $ /dlv -l40000 attach <process_pid> After running this command in the pod, connect your local debugg er to the exposed port.

If you encounter issues, review the troubleshooting docs, file an issue, or talk to us on the #ingress-nginx channel on the Kubernetes Slack server.
