Interactive cmd.run

[Stevearc]

I occasionally found myself wanting to run some command like 'ls' or 'cat' or 'netstat' on a bunch of servers at once, but it was a bit annoying to do:

salt -G 'roles:webserver' cmd.run "cat /etc/myapp/some_config_file.yaml"

So I wrote a short little python script that makes salt's cmd.run module more interactive. If nothing else, it's fun to play with.

Awesome! IMO, this should be an official tool included with salt.
salt-shell?

wow. This is absolutely great, thanks a lot for sharing! and yes, that
one should definitely be part of official saltstack :)

This is awesome, excellent work.

For those on Python2.6 (RHEL 6), change line 46 to this:

return lambda x: "\033[{0}m{1}\033[0m".format(termcode, x)

Oh, good catch on the string formatting! I'll just update it to use the old %s style instead, since that should work across all python versions.

This looks very nice, but how do I use it? is it a module that needs to go in /srv/salt/_modules?? 

Or do I just run it??

Just run it on your salt master. It hooks in and runs commands via salt.client.LocalClient

Nice. This is what I have in mind when I think about how I'd want to interact with salt-api on the command line. It'd be great to have this functionality combined with pepper[1] to serve as a general purpose shell for salt.

Your script (omnishell.py) do_shell function depends on subprocess.check_output, which is available only in Python 2.7 .

See: Subprocess library .

You may want to support Python 2.6 and later since RedHat/CentOS 5  and 6 both have only Python 2.6 available via EPEL.
