BoundSchema
BoundSchema CRD schema reference (group kube-bind.io)
Version v1alpha2
Properties
.apiVersion
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
.kind
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
.metadata
.spec
BoundSchemaSpec defines the desired state of the BoundSchema.
.spec.conversion
conversion defines conversion settings for the defined custom resource.
.spec.conversion.strategy
strategy specifies how custom resources are converted between versions. Allowed values are:
- "None": The converter only change the apiVersion and would not touch any other field in the custom resource.
- "Webhook": API Server will call to an external webhook to do the conversion. Additional information
is needed for this option. This requires spec.preserveUnknownFields to be false, and spec.conversion.webhook to be set.
.spec.conversion.webhook
webhook describes how to call the conversion webhook. Required when strategy is set to "Webhook".
.spec.conversion.webhook.clientConfig
clientConfig is the instructions for how to call the webhook if strategy is Webhook.
.spec.conversion.webhook.clientConfig.caBundle
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.
.spec.conversion.webhook.clientConfig.url
url gives the location of the webhook, in standard URL form
(scheme://host:port/path).
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.
.spec.conversion.webhook.conversionReviewVersions
conversionReviewVersions is an ordered list of preferred ConversionReview
versions the Webhook expects. The API server will use the first version in
the list which it supports. If none of the versions specified in this list
are supported by API server, conversion will fail for the custom resource.
If a persisted Webhook configuration specifies allowed versions and does not
include any versions known to the API Server, calls to the webhook will fail.
.spec.conversion.webhook.conversionReviewVersions[*]

The field pointed by this JSON path must be a string field (not a complex selector struct)
which contains a serialized label selector in string form.
More info: https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions#scale-subresource
If there is no value under the given path in the custom resource, the status.selector value in the /scale
subresource will default to the empty string.
.spec.versions[*].subresources.scale.specReplicasPath
specReplicasPath defines the JSON path inside of a custom resource that corresponds to Scale spec.replicas.
Only JSON paths without the array notation are allowed.
Must be a JSON Path under .spec.
If there is no value under the given path in the custom resource, the /scale subresource will return an error on GET.
.spec.versions[*].subresources.scale.statusReplicasPath
statusReplicasPath defines the JSON path inside of a custom resource that corresponds to Scale status.replicas.
Only JSON paths without the array notation are allowed.
Must be a JSON Path under .status.
If there is no value under the given path in the custom resource, the status.replicas value in the /scale subresource
will default to 0.
.spec.versions[*].subresources.status
status indicates the custom resource should serve a /status subresource.
When enabled:
1. requests to the custom resource primary endpoint ignore changes to the status stanza of the object.
2. requests to the custom resource /status subresource ignore changes to anything other than the status stanza of the object.
.status
BoundSchemaStatus defines the observed state of the BoundSchema.
.status.acceptedNames
acceptedNames are the names that are actually being used to serve discovery. They may be different than the names in spec.
.status.acceptedNames.categories
categories is a list of grouped resources this custom resource belongs to (e.g. ‘all’).
This is published in API discovery documents, and used by clients to support invocations like
kubectl get all.
.status.acceptedNames.categories[*]
.status.acceptedNames.kind
kind is the serialized kind of the resource. It is normally CamelCase and singular.
Custom resource instances will use this value as the kind attribute in API calls.
.status.acceptedNames.listKind
listKind is the serialized kind of the list for this resource. Defaults to “kindList”.
.status.acceptedNames.plural
plural is the plural name of the resource to serve.
The custom resources are served under /apis/<group>/<version>/.../<plural>.
Must match the name of the CustomResourceDefinition (in the form <names.plural>.<group>).
Must be all lowercase.
.status.acceptedNames.shortNames
shortNames are short names for the resource, exposed in API discovery documents,
and used by clients to support invocations like kubectl get <shortname>.
It must be all lowercase.
.status.acceptedNames.shortNames[*]
.status.acceptedNames.singular
singular is the singular name of the resource. It must be all lowercase. Defaults to lowercased kind.
.status.conditions
Conditions represent the latest available observations of the object’s state.
.status.conditions[*]
Condition defines an observation of a object operational state.
.status.conditions[*].lastTransitionTime
Last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.
.status.conditions[*].message
A human readable message indicating details about the transition. This field may be empty.
.status.conditions[*].reason
The reason for the condition’s last transition in CamelCase. The specific API may choose whether or not this field is considered a guaranteed API. This field may not be empty.
.status.conditions[*].severity
Severity provides an explicit classification of Reason code, so the users or machines can immediately understand the current situation and act accordingly. The Severity field MUST be set only when Status=False.
.status.conditions[*].status
Status of the condition, one of True, False, Unknown.
.status.conditions[*].type
Type of condition in CamelCase or in foo.example.com/CamelCase. Many .condition.type values are consistent across resources like Available, but because arbitrary conditions can be useful (see .node.status.conditions), the ability to deconflict is important.
.status.instantiations
Instantiations tracks the number of instances of the resource on the consumer side.
.status.storedVersions
storedVersions lists all versions of CustomResources that were ever persisted. Tracking these
versions allows a migration path for stored versions in etcd. The field is mutable
so a migration controller can finish a migration to another version (ensuring
no old objects are left in storage), and then remove the rest of the
versions from this list.
Versions may not be removed from spec.versions while they exist in this list.
