Mask tty's in docker acceptance nodesets

[ekohl]

Since beaker containers are privileged these tty's can interfere with
the system tty's. This can be an unpleasant surprise for those running
on Linux.

Is the tty required if we want to debug the container and enter it after a puppet run?

[ekohl]

I'm not sure if docker attach actually uses a tty (I'd guess a pts), but /sbin/init is non-interactive anyway. Beaker uses SSH server to connect I used that instead. A small script (that assumes you have one running container):

#!/bin/sh
container=$(docker ps --quiet)
ip=$(docker inspect $container | jq '.[0]["NetworkSettings"]["IPAddress"]' -r)
ssh -o UserKnownHostsFile=/dev/null root@$ip

The password is root.

Ah correct, we've got ssh. Should we document the ssh script somewhere in the README.md or in the CONTRIBUTING.md we place in each repository?

[bastelfreak]

@ekohl could you please add the script later to one of the readmes?
