Provide size as mandatory parameter while creating instance(troveclient)

[Harshada Mangesh Kakad]

usage: trove create <name> <flavor_id>
                    [--size <size>]
                    [--databases <databases> [<databases> ...]]
                    [--users <users> [<users> ...]] [--backup <backup>]
                    [--availability_zone <availability_zone>]
                    [--datastore <datastore>]
                    [--datastore_version <datastore_version>]
                    [--nic <net-id=net-uuid,v4-fixed-ip=ip-addr,port-id=port-uuid>]
                    [--configuration <configuration>]

Creates a new instance.

Positional arguments:
  <name> Name of the instance.
  <flavor_id> Flavor of the instance.

Optional arguments:
  --size <size> Size of the instance disk in GB.
  --databases <databases> [<databases> ...]
                        Optional list of databases.
  --users <users> [<users> ...]
                        Optional list of users in the form user:password.
  --backup <backup> A backup UUID.
  --availability_zone <availability_zone>
                        The Zone hint to give to nova.
  --datastore <datastore>
                        A datastore name or UUID.
  --datastore_version <datastore_version>
                        A datastore version name or UUID.
  --nic <net-id=net-uuid,v4-fixed-ip=ip-addr,port-id=port-uuid>
                        Create a NIC on the instance. Specify option multiple
                        times to create multiple NICs. net-id: attach NIC to
                        network with this UUID (required, if no port-id
                        specified), v4-fixed-ip: IPv4 fixed address for NIC
                        (optional), port-id: attach NIC to port with this UUID
                        (required, if no net-id specified).
  --configuration <configuration>
                        UUID of the configuration group to attach to the
                        instance.

As size here is optional parameter, if i try creating database instance with specifying the size it gives me an error as

$trove create test 8
ERROR: Validation error: instance 'volume' is a required property

Even in dashboard size is mandatory parameter
So even using troveclient, size should be a mandatory parameter.

The new usage could be :

usage: trove create <name> <size> <flavor_id>
                    [--databases <databases> [<databases> ...]]
                    [--users <users> [<users> ...]] [--backup <backup>]
                    [--availability_zone <availability_zone>]
                    [--datastore <datastore>]
                    [--datastore_version <datastore_version>]
                    [--nic <net-id=net-uuid,v4-fixed-ip=ip-addr,port-id=port-uuid>]
                    [--configuration <configuration>]

Creates a new instance.

Positional arguments:
  <name> Name of the instance.
  <size> Size of the instance disk in GB.
  <flavor_id> Flavor of the instance.

Optional arguments:
  --databases <databases> [<databases> ...]
                        Optional list of databases.
  --users <users> [<users> ...]
                        Optional list of users in the form user:password.
  --backup <backup> A backup UUID.
  --availability_zone <availability_zone>
                        The Zone hint to give to nova.
  --datastore <datastore>
                        A datastore name or UUID.
  --datastore_version <datastore_version>
                        A datastore version name or UUID.
  --nic <net-id=net-uuid,v4-fixed-ip=ip-addr,port-id=port-uuid>
                        Create a NIC on the instance. Specify option multiple
                        times to create multiple NICs. net-id: attach NIC to
                        network with this UUID (required, if no port-id
                        specified), v4-fixed-ip: IPv4 fixed address for NIC
                        (optional), port-id: attach NIC to port with this UUID
                        (required, if no net-id specified).
  --configuration <configuration>
                        UUID of the configuration group to attach to the
                        instance.

And if no size id specified the error should be:

$ trove create test 8
usage: trove create <name> <size> <flavor_id>
                    [--databases <databases> [<databases> ...]]
                    [--users <users> [<users> ...]] [--backup <backup>]
                    [--availability_zone <availability_zone>]
                    [--datastore <datastore>]
                    [--datastore_version <datastore_version>]
                    [--nic <net-id=net-uuid,v4-fixed-ip=ip-addr,port-id=port-uuid>]
                    [--configuration <configuration>]
