I've learned about Kubernetes, celery and how to deploy a stack consisting of ReactJS, Django, Celery, RabbitMQ, Redis and Postgres on Kubernetes with continous integration and deployment in place. Before the lockdown, I knew all of these technologies, but had never used them together.
It has taken me quite a long time to work out how all the moving pieces are fitting together, so I've decided to make a video tutorial explaining it all. If anybody is interested you sign up for the beta at https://indiemy.com
