CRD 生成
这些标记描述了如何从一系列 Go 类型和包中构建出一个 CRD。而验证标记则描述了实际验证模式的生成。
从 生成 CRDs 查看示例。
- groupName
- string
specifies the API group name for this package.
- string
- kubebuilder:printcolumn
- JSONPath
- string
- description
- string
- format
- string
- name
- string
- priority
- int
- type
- string
adds a column to "kubectl get" output for this CRD.
- JSONPath
- string
specifies the jsonpath expression used to extract the value of the column.
- description
- string
specifies the help/description for this column.
- format
- string
specifies the format of the column.
It may be any OpenAPI data format corresponding to the type, listed at https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md#data-types.
- name
- string
specifies the name of the column.
- priority
- int
indicates how important it is that this column be displayed.
Lower priority (higher numbered) columns will be hidden if the terminal width is too small.
- type
- string
indicates the type of the column.
It may be any OpenAPI data type listed at https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md#data-types.
- kubebuilder:resource
- categories
- string
- path
- string
- scope
- string
- shortName
- string
- singular
- string
configures naming and scope for a CRD.
- categories
- string
specifies which group aliases this resource is part of.
Group aliases are used to work with groups of resources at once. The most common one is “all“ which covers about a third of the base resources in Kubernetes, and is generally used for “user-facing“ resources.
- path
- string
specifies the plural "resource" for this CRD.
It generally corresponds to a plural, lower-cased version of the Kind. See https://book.kubebuilder.io/cronjob-tutorial/gvks.html.
- scope
- string
overrides the scope of the CRD (Cluster vs Namespaced).
Scope defaults to “Namespaced“. Cluster-scoped (“Cluster“) resources don‘t exist in namespaces.
- shortName
- string
specifies aliases for this CRD.
Short names are often used when people have work with your resource over and over again. For instance, “rs“ for “replicaset“ or “crd“ for customresourcedefinition.
- singular
- string
overrides the singular form of your resource.
The singular form is otherwise defaulted off the plural (path).
- kubebuilder:skip
don't consider this package as an API version.
- kubebuilder:skipversion
removes the particular version of the CRD from the CRDs spec.
This is useful if you need to skip generating and listing version entries for ‘internal‘ resource versions, which typically exist if using the Kubernetes upstream conversion-gen tool.
- kubebuilder:storageversion
marks this version as the "storage version" for the CRD for conversion.
When conversion is enabled for a CRD (i.e. it‘s not a trivial-versions/single-version CRD), one version is set as the “storage version“ to be stored in etcd. Attempting to store any other version will result in conversion to the storage version via a conversion webhook.
- kubebuilder:subresource:scale
- selectorpath
- string
- specpath
- string
- statuspath
- string
enables the "/scale" subresource on a CRD.
- selectorpath
- string
specifies the jsonpath to the pod label selector field for the scale's status.
The selector field must be the string form (serialized form) of a selector. Setting a pod label selector is necessary for your type to work with the HorizontalPodAutoscaler.
- specpath
- string
specifies the jsonpath to the replicas field for the scale's spec.
- statuspath
- string
specifies the jsonpath to the replicas field for the scale's status.
- kubebuilder:subresource:status
enables the "/status" subresource on a CRD.
- kubebuilder:unservedversion
does not serve this version.
This is useful if you need to drop support for a version in favor of a newer version.
- versionName
- string
overrides the API group version for this package (defaults to the package name).
- string
