permiussion denied

[McFcologne]

I have mapped all necessary folders and they also allow docker to write. The folder /rw was created from nagios, but it complains about permission issues.
the nmapped folder is /opt/nagios/var and i can see, nagios is creating files and foders, but then:
qh: Failed to init socket '/opt/nagios/var/rw/nagios.qh'. bind() failed: Permission denied

or isnt it a file access issue?
