I would even say, that you don't really need Docker at all. Just use some reasonable PaaS platform in the beginning - Heroku, Convox (my favorite), Cloud66.
The problem with PaaS is that they are not really friendly towards the local environment for development and QA.
They also don't consume gigabytes of memory, like docker client does on my Mac machine.
I also don't really need a resemblence with production environment on my local machine, if my architecture is simple enough.
More then that, if system becomes complicated - there is declarative NixOS.
All good points.
Just worth clarifying:
But, I agree. With all that, you may not need Kubernetes.
Why not? I've used Heroku for tons of Rails apps and also for handful of SPA ones that were developed locally. :thinkingface:
The good thing about a local environment that resembles production to the maximum extent possible is that you are integrating and facing problems that will not be faced in prod. PaaS services just reduce the length of similarity between your environment and the one your app will run on when your clients use it.
Ok. Now I see your point and agreed with it. Giving a second thought to the apps I've deployed to Heroku, they're small ones or in their initial stages. Once they get to be used by real users, they're moved to AWS or Linode.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
