getattrinfo: ENOTFOUND when using libnss plugins about beekeeper-studio

[rathboma]

That's interesting. Yeah I'm using the default node-psql library without the libpq plug-in. I wonder if it does hostname resolution differently.

Can you show me how to set up that specific DNS setup?

Sure! With one correction: there are two similar projects on Github, and I've linked to the wrong one, now corrected. This is all under Linux, other platforms may lack this feature.

However, supporting it should not require doing anything - that is, if you're using regular libc name lookup, and not something that uses DNS directly (skipping other mechanisms, which this is one of).

1. Install libnss-docker (Debians), nss-docker-git (Arch), or just compile and install from source.

2. If not done so already by package manager, ensure you have it inserted into /etc/nsswitch.conf as instructed on the project page. The exact position is not important, just that it's somewhere before dns. On my system, the relevant line looks like this:

   hosts: files mymachines docker mdns4_minimal [NOTFOUND=return] resolve [!UNAVAIL=return] dns mdns4 myhostname
   

3. Launch a postgres instance in docker

   docker run -it --rm --name bk-psql -e POSTGRES_PASSWORD=helloworld postgres:alpine
   

4. From now on you can ping bk-psql.docker or connect to it with psql -h bk-psql.docker -U postgres, on the same machine - not across the network

I think this is a limitation with the Snap version of Beekeeper. I bet if you tried the AppImage it would work. I've had lots of issues with the Snap version -- lots of security walls

[k3rni]

You are correct, it does work indeed in the AppImage version. I think we can close this, maybe with a couple lines in the docs about the snap version being more restricted.
