Traceback in azure_rm.py on Centos 7.3 with Azure python SDK rc6

[Jose Moreno]

Hi there,

I am trying to install Ansible on a clean, yum-updated CentOS 7.3 machine with the Azure modules, but azure_rm.py refuses to work. I installed the Azure SDK version rc6, and I could not spot any error. I am using file based authentication (~/.azure/credentials), with a file that works in another host. However, azure_rm.py will break:

[jose@vm-00 ~]$ python ./ansible/contrib/inventory/azure_rm.py --list

Traceback (most recent call last):

Any idea what is missing?

Thanks!

The doc is pretty clear about the supported Azure version beeting 2.0.0rc5. The python modules for Azure har unfortunately known for breaking changes betweens minor versions, so there's no way the Ansible modules will keep up with all the changes. Solution: Uninstall your current packages, and install 2.0.0rc5. rc5 has some include issues so you probably have to manually add some extra packages, but errors about that should be surfaced by Ansible. You can also manually verify by starting up python and try to import a module such as:

import msrestazure.azure_exceptions
