Updates k8s.io/kube-openapi from v0.0.0-20241212222426-2c72e554b1e7 to v0.0.0-20260502001324-b7f5293f4787 across api, kyaml, and kustomize modules, then propagates the change across all workspace modules via make workspace-sync. The new kube-openapi release switched from the monolithic go-openapi/swag (v0.23.0) to the refactored split sub-modules (go-openapi/swag/* v0.25.4). The old swag carried github.com/mailru/easyjson as a dependency; the new sub-modules do not. After go mod tidy, easyjson and josharian/intern are fully removed from all three module graphs. Also upgraded: github.com/google/gnostic-models v0.6.9 → v0.7.0 (pulled in by the same kube-openapi update). Signed-off-by: Davanum Srinivas <davanum@gmail.com>
Injection
This is an example of implementing an injection function.
This example is written in go and uses the kyaml libraries for parsing the
input and writing the output. Writing in go is not a requirement.
Function implementation
The function is implemented as an image, and built using make image.
The template is implemented as a go program, which reads a collection of input Resource configuration, and looks for invalid configuration.
Function invocation
The function is invoked by authoring a local Resource
with metadata.annotations.[config.kubernetes.io/function] and running:
kustomize build --enable-alpha-plugins local-resource/
This exits non-zero if there is an error.
Running the Example
Run the validator with:
kustomize build --enable-alpha-plugins local-resource/
This will add resource reservations to the Deployment. Change the tshirt-size
annotation from medium to small and rerun:
kustomize build --enable-alpha-plugins local-resource/
Observe that the reservations have changed.
