**expression** | **char \*** | expression will be evaluated by CEL to create a [JSON patch](https://jsonpatch.com/). ref: https://github.com/google/cel-spec expression must return an array of JSONPatch values. For example, this CEL expression returns a JSON patch to conditionally modify a value: [ JSONPatch{op: \"test\", path: \"/spec/example\", value: \"Red\"}, JSONPatch{op: \"replace\", path: \"/spec/example\", value: \"Green\"} ] To define an object for the patch value, use Object types. For example: [ JSONPatch{ op: \"add\", path: \"/spec/selector\", value: Object.spec.selector{matchLabels: {\"environment\": \"test\"}} } ] To use strings containing '/' and '~' as JSONPatch path keys, use \"jsonpatch.escapeKey\". For example: [ JSONPatch{ op: \"add\", path: \"/metadata/labels/\" + jsonpatch.escapeKey(\"example.com/environment\"), value: \"test\" }, ] CEL expressions have access to the types needed to create JSON patches and objects: - 'JSONPatch' - CEL type of JSON Patch operations. JSONPatch has the fields 'op', 'from', 'path' and 'value'. See [JSON patch](https://jsonpatch.com/) for more details. The 'value' field may be set to any of: string, integer, array, map or object. If set, the 'path' and 'from' fields must be set to a [JSON pointer](https://datatracker.ietf.org/doc/html/rfc6901/) string, where the 'jsonpatch.escapeKey()' CEL function may be used to escape path keys containing '/' and '~'. - 'Object' - CEL type of the resource object. - 'Object.<fieldName>' - CEL type of object field (such as 'Object.spec') - 'Object.<fieldName1>.<fieldName2>...<fieldNameN>` - CEL type of nested field (such as 'Object.spec.containers') CEL expressions have access to the contents of the API request, organized into CEL variables as well as some other useful variables: - 'object' - The object from the incoming request. The value is null for DELETE requests. - 'oldObject' - The existing object. The value is null for CREATE requests. - 'request' - Attributes of the API request([ref](/pkg/apis/admission/types.go#AdmissionRequest)). - 'params' - Parameter resource referred to by the policy binding being evaluated. Only populated if the policy has a ParamKind. - 'namespaceObject' - The namespace object that the incoming object belongs to. The value is null for cluster-scoped resources. - 'variables' - Map of composited variables, from its name to its lazily evaluated value. For example, a variable named 'foo' can be accessed as 'variables.foo'. - 'authorizer' - A CEL Authorizer. May be used to perform authorization checks for the principal (user or service account) of the request. See https://pkg.go.dev/k8s.io/apiserver/pkg/cel/library#Authz - 'authorizer.requestResource' - A CEL ResourceCheck constructed from the 'authorizer' and configured with the request resource. CEL expressions have access to [Kubernetes CEL function libraries](https://kubernetes.io/docs/reference/using-api/cel/#cel-options-language-features-and-libraries) as well as: - 'jsonpatch.escapeKey' - Performs JSONPatch key escaping. '~' and '/' are escaped as '~0' and `~1' respectively). Only property names of the form `[a-zA-Z_.-/][a-zA-Z0-9_.-/]*` are accessible. Required. | [optional]
