<html><head></head><body><div style="font-family: Verdana;font-size: 12.0px;"><div>Folks, I am new to Fabric and I have written quite a complicated fabfile.py script. It is used to install a product. The script resides along with a product on a Github. I don't want to clone the whole product to the local machine, so my question is simple - can I provide a network address of fabfile to fab command, something like this:<br/> <br/> <span style="font-size:14px;"><span style="font-family:courier new,courier,monospace;">    fab -H <host-name> -f ***@github.com:<my-repository>/<path>/<filename> task:<parms></span></span><br/>
<br/>
Pretty much any elegant idea of getting just a single file should suffice. But providing a network path for this file would be probably the best solution.<br/>
<br/>
Thanks,<br/>

There's no way to do this built in (nor do I see it as necessarily
being worth the development effort offhand - feels like a niche use
case and prioritzation is unfortunately a thing), but the first thing
that springs to mind is using shell tools like zsh's temporary-file
support, e.g.:

$ fab -H <target> -f =(curl
https://raw.githubusercontent.com/<user>/<repo>/<ref>/fabfile.py)
task:<params>

Where '=(<command>)' creates a local temporary file containing the
stdout of <command>, then expands into that temporary filename.
Presumably bash 4 and other common shells also offer something like
this.

You could also use Python for this, though it'd be more work - e.g.
have a setup task that performs the download, calls __import__ on the
temp file, then hands the resulting module object to Fabric's CLI
functions.

Bash does, though I can't recall offhand how to do it exactly. IIRC it's
pretty similar to zsh, but my memory is notoriously faulty.

You might check out Plumbum: https://pypi.python.org/pypi/plumbum

I think it would be fairly easy to rig something up with it.
