There are four GitOps Principles:
1-Resources Are Defined Declaratively A system managed by GitOps must have its desired state expressed declaratively.
2-Resource Definitions Are Versioned and Immutable The desired state is stored in a way that enforces immutability, enforces versioning, and retains a complete version history. Usually, Git is used for this.
3-Resource Definitions Are Pulled Automatically Software agents automatically pull the desired state declarations from the source. Here 'software agents' refers to the GitOps tool and, again, the source is usually Git.
4-The Desired State Is Continuously Reconciled With the Actual State Software agents (GitOps tools) continuously observe the actual system state and attempt to apply the desired state.
