# Validation
|
|
|
|
This is an example of implementing a validation 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](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](local-resource)
|
|
with `metadata.configFn` and running:
|
|
|
|
kustomize config run local-resource/
|
|
|
|
This exists non-zero if there is an error.
|
|
|
|
## Running the Example
|
|
|
|
Run the validator with:
|
|
|
|
kustomize config run local-resource/
|
|
|
|
This will return an error:
|
|
|
|
cpu-requests missing for container nginx
|
|
|
|
Now uncomment the resource reservations and run again:
|
|
|
|
kustomize config run local-resource/
|
|
|
|
This will return success
