I’m using ansible to apply configuration on a few servers which have their ssh key configured with the “no-pty” option, and I’m attempting to work out the best configuration settings to use with ansible on them.
I can use the “paramiko” transport after enabling “pty=False” in the configuration file and all of my playbooks execute without issue.
The documentation indicates that pipeline mode isn’t allocating a pty, but not all tasks seem to run without asking for a pty. I see in the source for the ssh transport that there is an explicit passing of “-tt” in some cases (likely not ones covered by pipeline mode?), but I’ve not fully understood why.
Would it be possible to implement a similar flag to the pty=False for the normal ssh transport, or is there a reason to explicitly request a tty for some connections?
I’d like to be able to take advantage of the ssh transport (and pipeline mode) if possible, but obviously I can fall back to paramkio if there is no other option.
