 This chart creates a single pod in a StatefulSet running Atlantis.  Atlantis persists Terraform [plan files](https://www.terraform.io/docs/commands/plan.html) and [lock files](https://www.terraform.io/docs/state/locking.html) to disk for the duration of a Pull/Merge Request.  These files are stored in a PersistentVolumeClaim to survive Pod failures.
