Configuration state file

As explained in Automating API Delivery

A configuration state file is a version-controlled file that declares the configuration state of a managed system.

A configuration state file is a version-controlled, declarative file that declares the desired configuration state of a managed API system. In an APIOps workflow, changing this file is the mechanism for changing configuration. section 9.4.1

A GitOps-managed configuration state file supports:

  • Immutable, versioned declarations with history, access controls, auditing, pull requests, and CODEOWNERS. section 9.4.1
  • Automated agents or deployment pipelines that pull the declared state. section 9.4.1
  • Continuous reconciliation of actual system state with desired state, including detection and correction of drift. section 9.4.1
  • A controlled alternative to manual API gateway UI changes, which may be error-prone and lack equivalent audit history. section 9.4.1

Compare the push-based deployment model with the pull-based model to understand how declared configuration reaches the managed system. section 9.4.1

How Automating API Delivery covers it

How deep it goes
Explains declarative state, versioning, automated pulls, reconciliation, drift, and governance controls.
Examples
Uses Git repositories, deployment pipelines, pull requests, CODEOWNERS, and API gateway UI changes as contrasting artifacts.
What it assumes
Assumes familiarity with version control and API configuration while defining declarative state and reconciliation principles.
What you can do after
Operate/configure API deployments by updating reviewed declarations instead of making unmanaged manual gateway changes.
How it connects
Connects declarative configuration with GitOps, infrastructure as code, version control, CI/CD, pull requests, and drift detection.
