How can I deploy botium speech processing on free cloud like okteto?

I’m using botium speech processing on docker in local environment. Using only frontend, STT, TTS and nginx via docker-compose. Many thanks to Florian Treml for providing awesome blog on medium. So I need to use these four on cloud as I have memory shortage. Just for fun and experiments need to deploy it on free cloud provider okteto. How can I achieve this ? I guess I need to make a dockerfile also.

i am pretty sure that there is not sufficient memory available for kaldi and marytts on free services
