ClusterHQ is now dead. They were an early container play, building a number of tools around Docker/etc. for the space.
Containers are a step between bare metal and VMs. FLocker (ClusterHQ’s product) is open source, and they were looking to monetize it in a different way (not on acquisition, but on support).
In this space though, Kubernetes reigns supreme. So competing products/projects need to adapt or outcompete.
And its very hard to outcompete something like k8s.
Again, I feel for the folks kicked to the street. And this is likely just the beginning.
