readResourceFragmentsFrom

public static io.fabric8.kubernetes.api.model.KubernetesListBuilder readResourceFragmentsFrom(String apiVersion,
                                                                                              String apiExtensionsVersion,

Read all Kubernetes resource fragments from a directory and create a KubernetesListBuilder which can be adapted later.

Parameters:

apiVersion - the api version to use

resourceFiles - files to add.

Returns:

the list builder

Throws:

IOException

getKubernetesResource

public static io.fabric8.kubernetes.api.model.HasMetadata getKubernetesResource(String defaultApiVersion,
                                                                                String apiExtensionsVersion,
                                                                                File file)

Read a Kubernetes resource fragment and add meta information extracted from the filename to the resource descriptor. I.e. the following elements are added if not provided in the fragment:

• name - Name of the resource added to metadata
• kind - Resource's kind
• apiVersion - API version (given as parameter to this method)

Parameters:

defaultApiVersion - the API version to add if not given.

apiExtensionsVersion - the API version for extensions

file - file to read, whose name must match FILENAME_PATTERN. @return map holding the fragment

Throws:

IOException
