Hello,

I am using Linux Ubuntu.

I am using docker container, where the localhost is named as 'nx' as default. (I didn't set it.)

When I run ping nx in host terminal, it works.

However, when I run ping nx in the container, it doesn't recognize nx.

Furthermore, when I set ROSMASTERURI=http://nx:11311 or the original IP of nx inside docker container,

The output is 'couldn't resolve publisher host [nx]`

How can I deal with this error?

When I run docker container, I already add --network=host argument in docker run command.

TIA
