It's been a while since I updated the Azure CLI. I ran into some weirdness getting my template to create a new Oracle Linux VM for me. I was, of course, still using azure CLI version 0.10.2. A quick npm re-install got me to 0.10.17 - not good enough. The latest download was still CLI 0.10.17. Strange - was everyone talking about CLI 2.0? Then I saw the Docker container installation instructions! Super easy! Do this and save your self some grief now and in the future.
