= Automation using Python and Paramiko =
If you are using the [https://www.paramiko.org/index.html Paramiko Python module] to automate your workflow, this is how you can make it work with the robot nodes:
<source lang=python>
# ====================================================================================================
#! /usr/bin/env python3
# ====================================================================================================
import os
import paramiko
# ====================================================================================================
key = paramiko.Ed25519Key.from_private_key_file("/home/username/.ssh/cc_allowed")
user = "username"
host = "robot.graham.alliancecan.ca"
ssh = paramiko.SSHClient()
# If the host is not known, it is OK.
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname=host, username=user, pkey=key)
cmd = "ls -l"
stdin, stdout, stderr = ssh.exec_command(cmd)
print("".join(stdout.readlines()))
ssh.close()
# ====================================================================================================
</source>
This code connects to the robot node on '''Graham''' using an automation key specified in CCDB and
executes the <code>ls -l</code> command to get the list of files.
Then prints the list to the screen.
Note, that it is important to install '''paramiko''' with the
$ pip install paramiko[all]
command. This will make sure that the support for the '''Ed25519''' key type will also be installed.
