Core concepts

The model Keystone works with: what you write, what it builds from it, and the rules it follows when reality and your plan disagree.

• Recipes

  The complete recipe format, field by field.

• Plans

  The device's desired state, and how applying one works.

• Dependencies

  Start order, restart cascades, and the three dependency types.

• Component state

  What each state means, and the liveness guarantees you can rely on.

• Reconcile and reuse

  Why re-applying a plan does not restart your stack.

• Datasets

  Data the component reads and the agent keeps fresh, without restarting it. {class=“children children-type-flat children-sort-”}
