jhipster kubernetes deployment has no redis - kubernetes

Question

i have designed several microservices using JHipster jdl studio, with redis cache.
i want to deploy them using kubernetes and docker-compose JHipster generator.
With docker-compose deployement generation, i see redis docker in the generated docker-compose.yml.
But in kubernetes no redis srvice or app generated.
I read the jhipster kubernetes generator source, but i dont see any redis generation in jhipster kubernetes generators and templates
Is there an issue or is there a reason for that?

I can't recall any specific reason. Guess it was just forgotten. Can you open an issue on github?
