We’re using “knife ssh” to deploy parts of our application. It seems,
though, that knife ssh returns “0” if it can’t connect to the host:
user@chef02:/tmp$ knife ssh ‘name:MikeEnv01C1’ 'ls /etc’
MikeEnv01C1 fstab makedev.d rmt
user@chef02:/tmp$ echo $?
… and to a host which was brought down:
user@chef02:/tmp$ knife ssh ‘name:SteveEnv02C’ ‘ls /etc’
WARNING: Failed to connect to -- Errno::ETIMEDOUT: Connection timed out -
user@chef02:/tmp echo $?
user@chef02:/tmp$ knife -v
Is this “As Designed”?
