I am currently in the process of developing a python code that connects to a remote brocade switch using the fabric module and issue some configuration commands. The problem I am facing is when it comes to commands that require an input from the user (i.e. yes/no).
I read several posts that have advised to use Fabric's native settings methods as well as wexpect but none have been successful.
I checked the following links but none were able to help with my code:
- how to handle interactive shell in fabric python
- How to answer to prompts automatically with python fabric?
- Python fabric respond to prompts in output
Below is an example of the command output that requires to be automated:
DS300B_Autobook:admin> cfgsave
You are about to save the Defined zoning configuration. This
action will only save the changes on Defined configuration.
If the update includes changes to one or more traffic isolation
zones, you must issue the 'cfgenable' command for the changes
to take effect.
Do you want to save the Defined zoning configuration only? (yes, y, no, n): [no]
The code that I have written for this is show below (tried to make it exactly the same as the output the command provides):
with settings(prompts={"DS300B_Autobook:admin> cfgsave\n"
"You are about to save the Defined zoning configuration. This\n"
"action will only save the changes on Defined configuration.\n"
"If the update includes changes to one or more traffic isolation\n"
"zones, you must issue the 'cfgenable' command for the changes\n"
"to take effect.\n"
"Do you want to save the Defined zoning configuration only? (yes, y, no, n): [no] " : "yes"}):
c.run('cfgsave')
If there is a way to have it display the output of the command to the screen and prompt me to provide the input that would also be reasonable solution.
