Unable to perform yang2swagger conversion from Docker installation

[arthurMll]

After building the docker image following the steps included in the README, I am not able to execute properly any yang2swagger conversion operation.

I am trying the following command: sudo docker run -it -v $(pwd):/usr/src/yang yang2swagger "-yang-dir . module-name" , inside a folder which contains all YANG files I would like to use for the conversion.

The execution is always retrieving the following output: 2019-07-29 16:37:51,843 [main] INFO c.mrv.yangtools.common.ContextHelper - adding . 2019-07-29 16:37:52,112 [main] INFO c.mrv.yangtools.common.SchemaBuilder -

Is it possible that the docker is not finding the yang files included in the host server namespace because it is trying to find them within the docker image namespace? If so how can I solve this?

Thanks in advance, Arturo.

Instead of -yang-dir . try -yang-dir /usr/src/yang. You seem to be referencing the wrong side of the mount that you made ($(pwd)).

Thanks @jdillard it works!
