patches
Patch resources
Patches (also call overlays) add or override fields on resources. They are provided using the
patches
Kustomization field.
The patches
field contains a list of patches to be applied in the order they are specified.
Each patch may:
- be either a strategic merge patch, or a JSON patch
- be either a file, or an inline string
- target a single resource or multiple resources
The patch target selects resources by group, version, kind, name, namespace, labelSelector and annotationSelector. Any resource which matches all the specified fields has the patch applied to it (regular expressions).
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
patches:
- path: patch.yaml
target:
group: apps
version: v1
kind: Deployment
name: deploy.*
labelSelector: "env=dev"
annotationSelector: "zone=west"
- patch: |-
- op: replace
path: /some/existing/path
value: new value
target:
kind: MyKind
labelSelector: "env=dev"
The name
and namespace
fields of the patch target selector are
automatically anchored regular expressions. This means that the value myapp
is equivalent to ^myapp$
.
