PiCluster is a simple way to manage Docker containers on multiple hosts. It will work on x86 or ARM CPU architectures that can run Docker and Node.js. PiCluster 2.3 will be out soon and I wanted to share the exciting new Elasticsearch integration currently in the dev branch. Traditionally, PiCluster had the ability to store its log output in Elasticsearch. Starting in PiCluster 2.3, node metrics such as disk, cpu, and memory utilization is stored also. With this ability, users can easily view their host metrics over time.
