How can you achieve the declarative GitOps principle in managing infrastructure and applications?

The first GitOps principle isDeclarative Descriptions. This means the desired system configuration (for infrastructure, services, and applications) is expressed declaratively and stored in version control. Git becomes the single source of truth.

“The desired system state must be expressed declaratively. This provides a clear, machine-readable blueprint for the system, and ensures that what is in Git is what should be running in the environment.”

Therefore,infrastructure and application configurations must be defined declaratively and stored in Git, not managed imperatively or manually.
