portrange parameter

[chenhayat]

Hi,
I am using in config.yaml in the portrange parameter

transports:

• type: web
  endpoint:
  type: tcp
  portrange: [1024,65535]

which works well.
Now, I am now trying to pass a parameter from outside of start_port_range and end_port_range but I get errors when it's trying to convert it regarding the string to int conversion.
I also tried to use it as following:

   portrange: !!seq
  - !!int {{ PORT_RANGE_START }}
  - !!int {{ PORT_RANGE_END }}

but got error: yaml.constructor.ConstructorError: expected a scalar node, but found mapping
I also tried to use the !template header but it does not know it.
Do you have any idea how I can pass a parameter here?

portrange must be a sequence of two integers, this is checked here:

crossbar/crossbar/common/checkconfig.py

Line 988 in 0089c1e

if 'portrange' in endpoint:

and the integers must be valid IP ports, which is checked via the helper here:

crossbar/crossbar/common/checkconfig.py

Line 865 in 0089c1e

def check_endpoint_port(port, message="listening/connection endpoint"):

Ok. Thank you!
