                                 --registry
                                 [--add-client-tokens]
                                 [--add-notifications]
                                 [--log-level]
                                 [--remove-client-tokens]
                                 [--remove-notifications]
                                 [--resource-group]
                                 [--sync-message-ttl]
                                 [--sync-schedule]
                                 [--sync-window]. The 1th example of the child command would be to use it to 'update the connected registry client tokens', the syntax is: az acr connected-registry update --registry mycloudregistry --name myconnectedregistry \
    --remove-client-tokens myTokenName1 --add-client-tokens myTokenName2 myTokenName3. The 2th example of the child command would be to use it to 'update the sync and window time of a connected registry', the syntax is: az acr connected-registry update --registry mycloudregistry --name myreadonlyacr \
    --sync-schedule "0 12 * * *" --sync-window PT4H. The parameter '--name -n' is required. It is used to name for the connected registry. name must be between 5 to 40 character long, start with a letter and contain only alphanumeric characters (including ‘_’ or ‘-’). name must be unique under the cloud acr hierarchy.. The parameter '--registry -r' is required. It is used to the login server of the cloud acr registry. must be the fqdn to support also azure stack.. The parameter '--add-client-tokens' is optional. client tokens to be added. use the format "--add-client-tokens [token_name1 token_name2 ...]" per token id.. The parameter '--add-notifications' is optional. list of artifact pattern to be added to notifications list. use the format "--add-notifications [pattern1 pattern2 ...]"..

The parameter '--remove-client-tokens' is optional. client tokens to be removed. use the format "--remove-client-tokens [token_name1 token_name2 ...]" per token id.. The parameter '--remove-notifications' is optional. list of artifact pattern to be removed from notifications list. use the format "--remove-notifications [pattern1 pattern2 ...]".. The parameter '--resource-group -g' is optional. name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--sync-message-ttl' is optional. determine how long the sync messages will be kept in the cloud. uses iso 8601 duration format.. The parameter '--sync-schedule -s' is optional. optional parameter to define the sync schedule. uses cron expression to determine the schedule. if not specified, the instance is considered always online and attempts to sync every minute..
