Chapter 5. TemplateInstance [template.openshift.io/v1] Description TemplateInstance requests and records the instantiation of a Template. TemplateInstance is part of an experimental API. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer). Type object Required spec 5.1. Specification Property Type Description apiVersion string 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 string 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 ObjectMeta_v2 metadata is the standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata spec object TemplateInstanceSpec describes the desired state of a TemplateInstance. status object TemplateInstanceStatus describes the current state of a TemplateInstance. 5.1.1. .spec Description TemplateInstanceSpec describes the desired state of a TemplateInstance. Type object Required template Property Type Description requester object TemplateInstanceRequester holds the identity of an agent requesting a template instantiation. secret LocalObjectReference_v2 secret is a reference to a Secret object containing the necessary template parameters. template object Template contains the inputs needed to produce a Config. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer). 5.1.2. .spec.requester Description TemplateInstanceRequester holds the identity of an agent requesting a template instantiation. Type object Property Type Description extra object extra holds additional information provided by the authenticator. extra{} array (string) groups array (string) groups represent the groups this user is a part of. uid string uid is a unique value that identifies this user across time; if this user is deleted and another user by the same name is added, they will have different UIDs. username string username uniquely identifies this user among all active users. 5.1.3. .spec.requester.extra Description extra holds additional information provided by the authenticator. Type object 5.1.4. .spec.template Description Template contains the inputs needed to produce a Config. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer). Type object Required objects Property Type Description apiVersion string 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 string 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 labels object (string) labels is a optional set of labels that are applied to every object during the Template to Config transformation. message string message is an optional instructional message that will be displayed when this template is instantiated. This field should inform the user how to utilize the newly created resources. Parameter substitution will be performed on the message before being displayed so that generated credentials and other parameters can be included in the output. metadata ObjectMeta_v2 metadata is the standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata objects array (RawExtension) objects is an array of resources to include in this template. If a namespace value is hardcoded in the object, it will be removed during template instantiation, however if the namespace value is, or contains, a USD{PARAMETER_REFERENCE}, the resolved value after parameter substitution will be respected and the object will be created in that namespace. parameters array parameters is an optional array of Parameters used during the Template to Config transformation. parameters[] object Parameter defines a name/value variable that is to be processed during the Template to Config transformation. 5.1.5. .spec.template.parameters Description parameters is an optional array of Parameters used during the Template to Config transformation. Type array 5.1.6. .spec.template.parameters[] Description Parameter defines a name/value variable that is to be processed during the Template to Config transformation. Type object Required name Property Type Description description string Description of a parameter. Optional. displayName string Optional: The name that will show in UI instead of parameter 'Name' from string From is an input value for the generator. Optional. generate string generate specifies the generator to be used to generate random string from an input value specified by From field. The result string is stored into Value field. If empty, no generator is being used, leaving the result Value untouched. Optional. The only supported generator is "expression", which accepts a "from" value in the form of a simple regular expression containing the range expression "[a-zA-Z0-9]", and the length expression "a{length}". Examples: from | value ----------------------------- "test[0-9]{1}x" | "test7x" "[0-1]{8}" | "01001100" "0x[A-F0-9]{4}" | "0xB3AF" "[a-zA-Z0-9]{8}" | "hW4yQU5i" name string Name must be set and it can be referenced in Template Items using USD{PARAMETER_NAME}. Required. required boolean Optional: Indicates the parameter must have a value. Defaults to false. value string Value holds the Parameter data. If specified, the generator will be ignored. The value replaces all occurrences of the Parameter USD{Name} expression during the Template to Config transformation. Optional. 5.1.7. .status Description TemplateInstanceStatus describes the current state of a TemplateInstance. Type object Property Type Description conditions array conditions represent the latest available observations of a TemplateInstance's current state. conditions[] object TemplateInstanceCondition contains condition information for a TemplateInstance. objects array Objects references the objects created by the TemplateInstance. objects[] object TemplateInstanceObject references an object created by a TemplateInstance. 5.1.8. .status.conditions Description conditions represent the latest available observations of a TemplateInstance's current state. Type array 5.1.9. .status.conditions[] Description TemplateInstanceCondition contains condition information for a TemplateInstance. Type object Required type status lastTransitionTime reason message Property Type Description lastTransitionTime Time LastTransitionTime is the last time a condition status transitioned from one state to another. message string Message is a human readable description of the details of the last transition, complementing reason. reason string Reason is a brief machine readable explanation for the condition's last transition. status string Status of the condition, one of True, False or Unknown. type string Type of the condition, currently Ready or InstantiateFailure. 5.1.10. .status.objects Description Objects references the objects created by the TemplateInstance. Type array 5.1.11. .status.objects[] Description TemplateInstanceObject references an object created by a TemplateInstance. Type object Property Type Description ref ObjectReference ref is a reference to the created object. When used under .spec, only name and namespace are used; these can contain references to parameters which will be substituted following the usual rules. 5.2.
