GitOps Principles v1.0.0

1. 1

   Declarative

   A system managed by GitOps must have its desired state expressed declaratively.

2. 2

   Versioned and Immutable

   Desired state is stored in a way that enforces immutability, versioning and retains a complete version history.

3. 3

   Pulled Automatically

   Software agents automatically pull the desired state declarations from the source.

4. 4

   Continuously Reconciled

   Software agents continuously observe actual system state and attempt to apply the desired state.
