# html-kube-tester # html-kube-tester
Workload to test application behavior while making changes on infrastructure.
Ingress is not included and have to be added on top.
Feel free to customize *replicas* and *content-git-repo* in *config* folder.
Git will be displayed in an iframe with node name on top.
Thanks to https://github.com/amoldalwai/RoadFighter.git for having something fun to display.
