Kube Ingress Template

For ingresses with lots of hostnames it's a hassle to keep the TLS and Hosts sections in sync. If some hosts have TLS required, some optional and others no TLS at all it's easy to get wrong. This tool might make it a little easier.

From a JSON input with lists of hostnames it'll generate a JSON ingress manifest.

Install

With Go installed, you can run

go get -u github.com/abh/kube-ingress-template
go install github.com/abh/kube-ingress-template

and the program should then be installed in $GOPATH/bin

Sample data

The input file has to be in ingress-hosts.json in the current directory.
