Get private IP with CLI

I am trying to get only the private IP v4 from the command line interface. I can use openstack server show myserver -c addresses just fine but it prints out a table / json and I am not able to find only the private v4 IP.

I'd like to have some command like

openstack server addresses -4 --private which would return

Is that implemented somewhere or do I need to write my own python script?

I don't think you can do this without further processing, but you can change the output format to value:

openstack server show INSTANCENAME -c addresses -f value | cut -f2 -d=

The above assumes that there is a single IPv4 address and no IPv6 address.

You can also use output format json and pipe the output into a parser like jq. Output formats shell and yaml might also be interesting.

FInally, you could submit the API request with curl and, again, use jq to parse it.
