Friend,

Openstack client version can impact some behaviours. Check the python-openstackclient version you are running, and consider running the version directly compatible with the epoxy release.

https://releases.openstack.org/teams/openstacksdk.html

According the to link, Epoxy release expects client version >=7.2.0, and <= 7.5.0

The SDK/Client is meant to be backwards compatible, but I have run into issues where running the wrong version has meant commands don’t work as expected or at all – the issue I had was with setting an openstack User’s MFA; the –enable-mfa argument was not understood or processed correctly because of the version mismatch.

Acquiring the correct version of the python-openstackclient resolved my problems. To ensure my colleagues did not run into similar issues, I containerised it so that we could have a consistent version with consistent plugins no matter our operating environment ( and it will allow for all tooling to be upgraded simultaneously when we upgrade the openstack version. )

Best of luck.

Kind Regards,

Joel McLean – Micron21 Pty Ltd
