SSH fingerpring

[YuriOsokin]

In the scripts, during connection to a new machine, openSSH requests to accept the fingerprint. It pops up a new window. However, this is not comfortable. I did not find any option to accept the fingerprint autometically, such as AutoAddPolicy policy in paramiko. Not typing 'yes' in the popup leads to "Host key verification failed".

I see that popup happens during subprocess run, but I did not find any solution to disable the check only for the current run. All the solutions are to disable the check completely.

Python-on-whales uses the normal docker client underneath. Meaning that it's the same issue you would have if you were to call docker in a bash script. The docker client uses the SSH client of the system (linux or windows or mac). So the normal fingerprinting issues apply.

In general, when you want to automate adding fingerprints when scripting with ssh, you can use ssh-keyscan. That's the solution I would recommend.
