Subject: Configuring nscd cache for mDNS
Date: Mon, 07 Nov 2022 17:33:44 +0000 (UTC)	[thread overview]
Message-ID: <f2fa17a5-1223-4f76-ac90-75abd98b71cb@tsvallender.co.uk> (raw)

Hello


I have a Docker container which advertises its name using mDNS,
e.g. hostname.local. However, when I restart the container,
Docker assigns the container a new IP (not sure why, doesn't
happen on other distros but that's probably not the point
here). nscd has the old IP cached and doesn't refresh even though
the container is advertising the new IP. I'm not sure why this
behaviour is occurring, or if it is the expected behaviour?

I'm don't know the correct fix here but am open to suggestions. I
presume one of the following:

- Configure nscd not to cache mDNS addresses
- Shorten the length of time these addresses are cached for

If someone could suggest why this is occurring, or provide an
example of how to do one of the above, that would be brilliant.

Thanks,

Trevor Vallender.
