az acs kubernetes get-credentials fails when specifying ssh-key-file

See original GitHub issue

As of v2.0.4, I get an error when I use --ssh-key-file along with az acs kubernetes get-credentials (the command works if my key is in the default location of ~/.ssh/id_rsa).

I took a look at past commits and I believe https://github.com/Azure/azure-cli/commit/b26248718cc1a66e27836b0c5d238cdc2bfcc997 by @derekbekoe and @brendandburns might’ve introduced the bug. It looks like ‘pkey’ is set to ‘None’ inside ‘SecureCopy’, but never updated. I also couldn’t figure out where the newly-added ‘keys’ array was used in that function

Here’s my full error:

(and fwiw, I’m going to improve testing too so that I don’t break this again in the future)

It will be released later this week or next week. Alternatively, we have nightly builds. Since it was merged today, it’ll be available tomorrow. https://github.com/Azure/azure-cli/#nightly-builds
