Maelstrom is a HTTP reverse proxy and request router that also includes support for starting and stopping containers in response to request activity.



Design and dependencies

Maelstrom is designed to have a very small operational footprint. Each node runs a single process (maelstromd) and bootstraps cluster state from a shared database. Nodes are peers (i.e. there are no manager / worker distinctions) and nodes compete to acquire locks to perform various activities such as auto-scaling and cron support.

Each node in the cluster must be running Docker and must have access to a MySQL or Postgres database.

Maelstrom consists of two binaries:
