# 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.
