Proxmox Docker Monster! Running 13000 containers on a single host!
Following up on a blog post that is hot off the press on my site, I wanted to create the video form of this topic. I have been playing around with Proxmox and Docker containers in the lab. With my SuperMicro E300-9D hardware with 16 cores and 128 GB of memory, how many containers can you run?
