Show HN: Redspread (YC W16) – CLI to deploy Docker to Kubernetes in one command

Hey everyone, cofounders of Redspread here, Mackenzie and Dan. We built Spread, our open source command line tool to build and deploy Docker to Kubernetes in one command, to enable rapid iteration with Kubernetes and provide the easiest way to deploy Docker to prod.

Our mission is to enable people to own their own deployment processes and infrastructure, and we're very passionate about that (see our philosophy.md).

Would love your angry bug reports, feature requests, and feedback!

Hey thanks! So we evaluated a bunch of different orchestrator options when we were first thinking about Redspread, and Kubernetes was opinionated in a way we liked the best. Google's been running containers in production for a decade now, so a lot of their learnings and best practices are baked into Kube. This article does a pretty good job of laying out the pros/cons of different orchestrators: http://code.haleby.se/2016/02/12/why-we-chose-kubernetes/

So in 1.2, Deployment API facilitates the transition from state to state for an RC or a pod. This provides a basic form of revision history, but isn't "versioning" - it's more if you could only go back one step.

For us, we see the big use case for full deployment versioning when there are multiple kube objects and config files to track. Already this is introducing some complication into developer workflows - ex: I have a bunch of services, rc's, and secrets. They are parameterized by this configuration. Now I've updated the configuration. I want to propagate that configuration to my cluster "with no downtime” - right now there isn't an easy way to do this.

So what exactly is Kubernetes?

Great to see such a great tool for deployments. Will you be adding support for managing multiple containers in a single deployment and scaling deployments up/down?
