“The team used ImageUpdateAutomation before lunch, so the release did not sprint into production wearing untied shoes.”

Immutable Artifact is a GitOps term for a build or package that should not change after publication. It helps teams, humans, and agents compare declared source state with running systems, then act without pretending a deployment did more than the evidence shows. Source context: OpenGitOps principles.

Kubernetes Manifest is a GitOps term for YAML or JSON that declares Kubernetes resource state. It helps teams, humans, and agents compare declared source state with running systems, then act without pretending a deployment did more than the evidence shows. Source context: Argo CD documentation; Kubernetes controller pattern.

“The team used Kubernetes Manifest before lunch, so the release did not sprint into production wearing untied shoes.”

Kustomize Controller is a GitOps term for a Flux controller that applies Kustomize-based configuration. It helps teams, humans, and agents compare declared source state with running systems, then act without pretending a deployment did more than the evidence shows. Source context: Flux documentation.

“The team used Kustomize Controller before lunch, so the release did not sprint into production wearing untied shoes.”

Kustomize Overlay is a GitOps term for a layer of patches and settings applied on top of a base manifest. It helps teams, humans, and agents compare declared source state with running systems, then act without pretending a deployment did more than the evidence shows. Source context: Argo CD documentation; Flux documentation.

“The team used Kustomize Overlay before lunch, so the release did not sprint into production wearing untied shoes.”

Kyverno Policy is a GitOps term for a Kubernetes-native policy rule for validating, mutating, or generating resources. It helps teams, humans, and agents compare declared source state with running systems, then act without pretending a deployment did more than the evidence shows. Source context: Kubernetes controller pattern.

“The team used Kyverno Policy before lunch, so the release did not sprint into production wearing untied shoes.”

Live State is a GitOps term for the current running condition of a cluster, application, or resource. It helps teams, humans, and agents compare declared source state with running systems, then act without pretending a deployment did more than the evidence shows. Source context: Argo CD documentation; Kubernetes controller pattern.

“The team used Live State before lunch, so the release did not sprint into production wearing untied shoes.”

Manifest Digest is a GitOps term for a content hash that identifies a specific manifest or artifact. It helps teams, humans, and agents compare declared source state with running systems, then act without pretending a deployment did more than the evidence shows. Source context: OpenGitOps principles.

“The team used Manifest Digest before lunch, so the release did not sprint into production wearing untied shoes.”

Manual Sync is a GitOps term for a human-triggered or operator-triggered application of desired state.
