This image contains a few handy Kubernetes utilities.

Standard tools

Contains kubectl, curl and jq. With those tools, you can write shell scripts that do a lot with the Kubernetes API.

fix-ingress-lb

Like Service resources, Ingress resources can have loadBalancer section in their status that is supposed to be set to the external hostname to reach the ingress controller. However, Ingress controllers are not aware when they are running behind an external load balancer and may not set this correctly for the Ingresses they manage. This tool will watch for Ingresses and update their loadBalancer status to match that of a given Service.

Usage: fix-ingress-lb INGRESS-CONTROLLER-SERVICE-NAMESPACE INGRESS-CONTROLLER-SERVICE-NAME [INGRESS-CLASS]

This will adjust any Ingresses in the given INGRESS_CLASS (or all Ingresses if none specified) to have the same loadBalancer status as the given INGRESS_CONTROLLER-SERVICE.
