Re: [Fab-user] fabric2 cd with multiple servers

[Ben Abrams]

Lamont,

It's honestly been a while since I used fabric and have not really stayed up on it so apologies if my research was too hastily done and incorrect. There does seem to be the functionality you are looking for in both fabric 1 and 2 (alpha) though they have some slight differences.

In fabric 1.x it came from here: https://github.com/fabric/fabric/blob/1.14/fabric/context_managers.py like this: https://github.com/fabric/fabric/blob/1.14/fabric/context_managers.py#L20-L21

In fabric 2.x they broke out that into the invoke library here: https://github.com/pyinvoke/invoke/blob/master/invoke/context.py like this: https://github.com/pyinvoke/invoke/blob/master/invoke/context.py#L328-L329

Hope this helps,

I'm learning the fabric2 api and wanted to know the best way to run a command with a particular working directory on a set of servers.

The README indicates that there is a 'execute' method on Group, but this doesn't seem to be the case. I was able to get code below to work by calling run on each connection in the group. Is there a more succinct way to do this besides the "cd foo && cmd" method? Or am I overlooking something?

from fabric import ThreadingGroup

g=ThreadingGroup('host1','host2')

g.run('cd /tmp && ls foo')

-- or --

from fabric import ThreadingGroup

g=ThreadingGroup('host1','host2')

for c in g:

    with c.cd('/tmp'):

        c.run('ls foo')
