Remote exec and copy commands
|
|
=============================
|
|
|
|
Cdist interacts with the target host in two ways:
|
|
|
|
- it executes code (__remote_exec)
|
|
- and it copies files (__remote_copy)
|
|
|
|
By default this is accomplished with ssh and scp respectively.
|
|
The default implementations used by cdist are::
|
|
|
|
__remote_exec: ssh -o User=root
|
|
__remote_copy: scp -o User=root
|
|
|
|
The user can override these defaults by providing custom implementations and
|
|
passing them to cdist with the --remote-exec and/or --remote-copy arguments.
|
|
|
|
For __remote_exec, the custom implementation must behave as if it where ssh.
|
|
For __remote_copy, it must behave like scp.
|
|
Please notice, custom implementations should work like ssh/scp so __remote_copy
|
|
must support IPv6 addresses enclosed in square brackets. For __remote_exec you
|
|
must take into account that for some options (like -L) IPv6 addresses can be
|
|
specified by enclosed in square brackets (see :strong:`ssh`\ (1) and
|
|
:strong:`scp`\ (1)).
|
|
|
|
With this simple interface the user can take total control of how cdist
|
|
interacts with the target when required, while the default implementation
|
|
remains as simple as possible.
