Minimum Specification

[J Wo]

Is there any information on the Hardware specifications of CoreOS.

More specifically:

    a Minimum CPU specification - will CoreOS run on older generations of hardware such as Pre-Core2 Intel CPU's

    a Min/Max Memory Requirement for the CoreOS System Area excluding Docker Application,

    a Minimum Memory for each Docker Application,


I cannot seem to locate such information on the CoreOS Website.

This information would help me determine what older hardware I might resurrect to evaluate/use CoreOS on.

At the moment I have no desire to setup Clusters of Machines (Real/Virtual), at least until I am able to use it properly on a single machine.

I couldn't find anything official but my experience:

64Bit, I know of no other requirements.

My idle docker machine is consuming ~400MB, most of which is the Journal. I had trouble starting when I set the initial memory balloon to 256MB, I would recommend at least 512 (And then configure a swap disk, I think they changed filesystems but btrfs doesn't support swapfiles).

Docker is pretty thin. I doubt you would notice a per container overhead. So just look at what you are running in the container.

Also don't forget to consider the disk cache, If you are tight on ram then disk IO will suffer.

Tl;dr: If it is 64-bit and can run virtual machines, it will run containers MUCH better.
