I've got the following open ssh client command to setup a local port forwarding:
ssh -i <keyfile> -o HostKeyAlgorithms=ssh-rsa -o StrictHostKeyChecking=no -L <localPort>:<remoteHost>:<remotePort> <user>@<remoteServerIP> -fN
How can I do exactly the same in Python with the sshtunnel library? https://sshtunnel.readthedocs.io/en/latest/
The sshtunnel's documentation has no example for using key files, in this case the key file contains a RSA PRIVATE KEY.
