                           [--update-dependent-resources]. The 1th example of the child command would be to use it to 'create a workspacehub from a yaml specification file', the syntax is: az ml workspace-hub create --file workspace-hub.yml --resource-group my-resource-group. The parameter '--resource-group -g' is required. It is used to name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--additional-workspace-storage-accounts -a' is optional. a list of comma separated resource ids of existing storage accounts that will be utilized in addition to the default one.. The parameter '--container-registry -c' is optional. arm id of the container registry associated with this workspacehub.. The parameter '--default-workspace-resource-group -d' is optional. a destination resource group for any project workspaces that join the workspacehub, it will be the workspacehub's resource group by default.. The parameter '--description' is optional. description of the azure ml workspacehub.. The parameter '--display-name' is optional. display name for the workspacehub.. The parameter '--file -f' is optional. local path to the yaml file containing the azure ml workspace-hub specification. the yaml reference docs for workspace-hub can be found at: https://aka.ms/ml-cli-v2-workspace-hub-entity-yaml-reference.. The parameter '--key-vault -k' is optional. arm id of the key vault associated with this workspacehub.. The parameter '--location -l' is optional. the location to be used for the new workspacehub.. The parameter '--managed-network -m' is optional. managed network isolation mode for the workspacehub.. The parameter '--name -n' is optional. name of the azure ml workspacehub.. The parameter '--no-wait' is optional. do not wait for workspacehub creation to finish.. The parameter '--primary-user-assigned-identity -p' is optional. arm identifier of primary user assigned managed identity, in case multiple ones are specified. also the default managed identity for clusterless compute.. The parameter '--public-network-access' is optional. allow public endpoint connectivity when a workspacehub is private link enabled.. The parameter '--set' is optional. update an object by specifying a property path and value to set. example: --set property1.property2=<value>.. The parameter '--storage-account -s' is optional. arm id of the storage account associated with this workspacehub.. The parameter '--tags' is optional. space-separated key-value pairs for the tags of the object.. The parameter '--update-dependent-resources -u' is optional. specifying --update_dependent_resources, gives your consent to update the workspace dependent resources. updating the workspace-attached azure container registry or application insights resource may break lineage of previous jobs, deployed inference endpoints, or your ability to rerun earlier jobs in this workspace..
