Python - connecting SSH wrappers to remote devices with threading
The problem I would like to solve is get the following:
- instantiate 5-10 host ssh sessions simultaneously (threading??)
- leave the connections established and awaiting for external calls
- execute predifined methods under the Host class (such as getUberImportantDetails() )
expose information and selected methods for ssh wrappers with flask rest API.
class Host():
def __init__(self, host, user, psw):
super().__init__(host, user, psw)
self.bypass = ''
self.state = "IDLE"
def connect(self):
self.ssh = paramiko.SSHClient()
<a lot of regexp based SSH processing>
def getUberImportantDetails(self):
output = self.execute("show very important data")
return SRE4BGPNeighborParser(output)
Host's init() method has to get host ip address, username and password.
Before getting any information out of the object i need to run the connect method to establish the SSH connection over a range of jumphosts.
When Host class connect routing is finished, I am ready to interact with the remote device.
I was able to initialize the class object with a thread wrapper, but I also want to leave the threads running after connect() function done all the work and the handler is ready for interaction with the remote device. How do i do it nicely?
Is there a better way to address my problem?
def threaded(fn):
def wrapper(*args, **kwargs):
thread = threading.Thread(target=fn, args=args, kwargs=kwargs)
thread.start()
return thread
return wrapper
class ThreadHost(threading.Thread, Host):
def __init__(self, host, user, psw):
super(Host, self).__init__(host, user, psw)
self.bypass = ''
self.state = "IDLE"
@threaded
def run(self):
print("Starting connection to {}".format(self.host))
self.connect()
