        kg_traefik2 is a builder for [KubraGen](https://github.com/RangelReale/kubragen) that deploys 
        a [Traefik 2](https://traefik.io/) server in Kubernetes.
        
        [KubraGen](https://github.com/RangelReale/kubragen) is a Kubernetes YAML generator library that makes it possible to generate
        configurations using the full power of the Python programming language.
