Using an SSH keyfile with Fabric

Question

How do you configure fabric to connect to remote hosts using SSH keyfiles (for example, Amazon EC2 instances)?

Answer 1

None of these answers worked for me on py3.7, fabric2.5.0 and paramiko 2.7.1.

However, using the PKey attribute in the documentation does work: http://docs.fabfile.org/en/2.5/concepts/authentication.html#private-key-objects

from paramiko import RSAKey
ctx.connect_kwargs.pkey = RSAKey.from_private_key_file('path_to_your_aws_key')
with Connection(ctx.host, user, connect_kwargs=ctx.connect_kwargs) as conn:
    //etc....
