- Platform9 Managed OpenStack
- Microversion >= 2.44
Cause
As described in python-openstackclient-581418, the change_I1848db384a825d3b166f113b30ebad92113af8e5_ deprecated nova 'remove_fixed_ip' action from microversion 2.44, and change Icb667973c65d26395db660b1c7b919550db66d08 removed support from novaclient side. The new linked patch re-implements 'remove_fixed_ ip' function with interface_detach interface from novaclient but the same hasn't been merged yet upstream.
Resolution
Ways to workaround the limitation:
- Remove the Fixed IP from the Platform9 U/I. Select
Instance => Network => Remove Fixed IP. - Use python-novaclient===9.1.3 compatible with Openstack Pike on your local client machine to run Openstack operations.
- Download the requirements.txt file from Platform9's Github.
- Run the below-mentioned command to install the packages specified in the file with their correct versions.
pip install --upgrade --requirement <filename> --constraint https://raw.githubusercontent.com/openstack/requirements/stable/pike/upper-constraints.txtThis will install OpenStack CLI clients for the core OpenStack projects in addition to several other supported projects for the Pike release.
