Implement check for mismatching package versions across deployed applications #206

Open esunar opened 2 years ago

esunar commented 2 years ago

Recently we encountered LP:1859649 where neutron-common package was updated on nova-compute-kvm units but not updated on neutron-api, and neutron-gateway resulted in an unusable cloud.

We should create a package version check that notifies us when packaged versions are not matching across units in the cloud. It might be loosely implemented such that the exact units and packages that get checked can be configurable via a parameter.
