This is the documentation for the Ingress NGINX Controller.
It is built around the Kubernetes Ingress resource, using a ConfigMap to store the controller configuration.
You can learn more about using Ingress in the official Kubernetes documentation.
See Deployment for a whirlwind tour that will get you started.
If you are using Ingress objects in your cluster (running Kubernetes older than v1.22), and you plan to upgrade to Kubernetes v1.22, please read the migration guide here.
