Property Type Description

Property	Type	Description
`conversion`	`object`	CustomResourceConversion describes how to convert different versions of a CR.
`group`	`string`	group is the api group of the defined custom resource. The custom resources are served under `/apis/<group>/…`. Must match the name of the CustomResourceDefinition (in the form `<names.plural>.<group>`).
`names`	`object`	CustomResourceDefinitionNames indicates the names to serve this CustomResourceDefinition
`preserveUnknownFields`	`boolean`	preserveUnknownFields indicates that object fields which are not specified in the Openapi schema should be preserved when persisting to storage. apiVersion, kind, metadata and known fields inside metadata are always preserved. This field is deprecated in favor of setting `x-preserve-unknown-fields` to true in `spec.versions[].schema.openapiV3Schema`. See https://kubernetes.io/docs/tasks/access-kubernetes-api*/custom-resources/custom-resource-definitions/#pruning-versus-preserving-unknown-fields for details.
`scope`	`string`	scope indicates whether the defined custom resource is cluster- or namespace-scoped. Allowed values are `Cluster` and `Namespaced`.
`versions`	`array`	versions is the list of all api versions of the defined custom resource. Version names are used to compute the order in which served versions are listed in api discovery. If the version string is "kube-like", it will sort above non "kube-like" version strings, which are ordered lexicographically. "Kube-like" versions start with a "v", then are followed by a number (the major version), then optionally the string "alpha" or "beta" and another number (the minor version). These are sorted first by GA > beta > alpha (where GA is a version with no suffix such as beta or alpha), and then by comparing major version, then minor version. An example sorted list of versions: v10, v2, v1, v11beta2, v10beta3, v3beta1, v12alpha1, v11alpha2, foo1, foo10.
`versions[]`	`object`	CustomResourceDefinitionVersion describes a version for CRD.

Property Type Description

Property	Type	Description
`caBundle`	`string`	caBundle is a PEM encoded CA bundle which will be used to validate the webhook’s server certificate. If unspecified, system trust roots on the apiserver are used.
`service`	`object`	ServiceReference holds a reference to Service.legacy.k8s.io
`url`	`string`	url gives the location of the webhook, in standard URL form (`scheme://host:port/path`). Exactly one of `url` or `service` must be specified. The `host` should not refer to a service running in the cluster; use the `service` field instead. The host might be resolved via external DNS in some apiservers (e.g., `kube-apiserver` cannot resolve in-cluster DNS as that would be a layering violation). `host` may also be an IP address. Please note that using `localhost` or `127.0.0.1` as a `host` is risky unless you take great care to run this webhook on all hosts which run an apiserver which might need to make calls to this webhook. Such installs are likely to be non-portable, i.e., not easy to turn up in a new cluster. The scheme must be "https"; the URL must begin with "https://". A path is optional, and if present may be any string permissible in a URL. You may use the path to pass an arbitrary string to the webhook, for example, a cluster identifier. Attempting to use a user or basic auth e.g. "user:password@" is not allowed. Fragments ("#…") and query parameters ("?…") are not allowed, either.

Parameter	Type	Description
`continue`	`string`	The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
`dryRun`	`string`	When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
`fieldSelector`	`string`	A selector to restrict the list of returned objects by their fields. Defaults to everything.
`gracePeriodSeconds`	`integer`	The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
`labelSelector`	`string`	A selector to restrict the list of returned objects by their labels. Defaults to everything.
`limit`	`integer`	limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
`orphanDependents`	`boolean`	Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
`propagationPolicy`	`string`	Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
`resourceVersion`	`string`	resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
`resourceVersionMatch`	`string`	resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
`timeoutSeconds`	`integer`	Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

HTTP method: GET
Description: list or watch objects of kind CustomResourceDefinition

Table 5. Query parameters
Parameter	Type	Description
`allowWatchBookmarks`	`boolean`	allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
`continue`	`string`	The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token.
