1000 Docker Containers with Open Metal Cloud

I had the opportunity to deploy 1000 Docker Containers on a three-node OpenStack private cloud using Open Metal Cloud's platform. The containers were almost entirely identical and had low resource usage, which helped make this possible. However, I still ran into challenges with provisioning the containers without overwhelming Docker on the three hardware nodes. This post talks about the deployment and architecture from a high level; it is meant to serve as a record and retrospective for me in case I need to do this in the future. I had to complete the deployment in three days to meet the deployment's requirements. That's right. 1000 Docker containers deployed from scratch in 72 hours.
