kandi X-RAY | nss-mdns Summary
nss-mdns is a plugin for the GNU Name Service Switch (NSS) functionality of the GNU C Library (glibc) providing host name resolution via Multicast DNS (aka Zeroconf, aka Apple Rendezvous, aka Apple Bonjour), effectively allowing name resolution by common Unix/Linux programs in the ad-hoc mDNS domain .local. nss-mdns provides client functionality only, which means that you have to run a mDNS responder daemon seperately from nss-mdns if you want to register the local host name via mDNS. I recommend Avahi. nss-mdns is very lightweight (9 KByte stripped binary .so compiled with -DNDEBUG=1 -Os on i386, gcc 4.0), has no dependencies besides the glibc and requires only minimal configuration. nss-mdns tries to contact a running avahi-daemon for resolving host names and addresses and making use of its superior record cacheing. If Avahi is not available at lookup time, the lookups will fail.

QUESTION
I am a newbie trying to learn docker. I am trying to dockerize kafka installation and stuck with a non zero exit code. I would like to debug the issue and find out the reason. How to debug a docker file.
I tried executing the dockerd in debug mode by using dockerd -D
.But this did not give any detailed logging.
I am running my script inside a vagrant dev box. Is there any way i can execute the build in debug mode.
Below is my docker file.
...ANSWER
Answered 2017-Nov-19 at 03:54Always use apt-get install -y
so there are no user prompts.
The CMD
will need to run in the foreground as well and doesn't need to use a log file. Docker has a stdout/stderr logging interface accessible with docker logs CONTAINER
.
QUESTION
The problem is at subconfig1.vm.provision ... , any advices on how should i proceed ? After initializing the VM's Vagrant tells me that SSH faild to do the job, because connection is refused. I can make this work, but only manually, inserting the password, my big question here is how do I overpass the password to make this workflow automatically.

Answered 2017-Sep-26 at 16:11You need to pass the private key so you can successfully login.
- retrieve which private key is used
Generally the file is under .vagrant/machines//provider/private_key
You can also run vagrant ssh-config
to find out which private key is being used for all machines:
