Simple example executing commands via ssh with Paramiko

ssh_command.py

#!/usr/bin/env python
import paramiko

SSH_HOST='host.example.com'
SSH_USER='admin_user'
SSH_KEY='/home/user/.ssh/id_rsa'

def do_ssh_command(command):
    try:
        with paramiko.SSHClient() as client:
            client.load_system_host_keys()
            client.connect(SSH_HOST, username=SSH_USER, key_filename=SSH_KEY)
            _stdin, stdout, _stderr = client.exec_command(command)
            for line in iter(lambda: stdout.readline(2048).rstrip(), ""):
                print(line)
            stderr = _stderr.read()
            if len(stderr) > 0:
                raise SystemExit(stderr)
    except Exception as err:
        raise SystemExit("There was an issue with ssh command: {}".format(err))
