Hello Krissura,
dnstap logging data are controlled with this directive (named.conf.options):

	/* where to capture to: file or unix (socket) */
	//dnstap-output file "/etc/bind/named.tap";
	dnstap-output unix "/etc/bind/dnstap.sock";

But for read the content (file o socketunix) your need a dnstap reader:

Ciao!

ps: in case of dnstap-output unix the socketfile are created by reader not by bind.

This is what we are trying to do
The default option works
We are trying to modify the named.config.options
Building the docker file and starting it seems to give an error . I am trying to find the log file to trace the error . There is no log file in /var/log/syslog or something like that

 I try docker logs command and it shows the log files. 

  Where are  the bind / named log files present on the docker container ?

docker logs bind_sinkhole show bind log (bind was runned in foreground), inside the docker not any log are saved...
Alternative idea is to install syslog/rsyslog inside the docker and send log to remote syslog server.
