Most folks building software at startups and scale-ups should avoid Kubernetes and other premature optimisations. If your company uses Kubernetes, you are likely expending energy on something that doesn't take you towards your mission. You have probably fallen into the trap of premature optimisation.
Please don't take this post to be only aimed against Kubernetes. It is not. I am directing this post at every possible bit of premature optimisation engineers make in the course of building software.
Yes!

The same way it works now. Find an image you want to run, and docker run it.
The author advocates using a high-level PaaS. For sure working directly with VMs is the wrong answer to premature optimization, but as an early stage startup, there's plenty of services around that you basically just need to point your Git repo at and you'll have a reasonable infrastructure set up for you.
