Feature: enable configured SSH destinations in remote Juju options #96
Description
Problem
When running remote Jockey commands with juju-jockey -H <hostname> ..., that hostname does not consider configured SSH hosts.
Proposed Feature
juju-jockey -H <hostname> should consider SSH configs to determine the host's IP.
Additional Context
Below is a quick example, which has been sanitized. In this example, I am only using the -H flag, which should not be an issue, so far as I understand. This problem seems to occur well before any other flags are even considered.
Here is a snippet of my SSH config:
Host infra.customer.cloud infra1.customer.cloud...
Hostname 10.111.134.1
ProxyJump vpn.customer.cloudWhen I run the below command, it fails to find this IP address. Again, this is sanitized, but I ran the real thing on my end:
juju-jockey -H infra.customer.clouds units
