To Myself,

Pain

The SysAdmins have added some new mandatory tags for Azure Resources which breaks the deployment unless they are present in the bicep template.

Currently the tag is hard-coded as dev/test which - for the time being - is okay, but will need to be done properly before we deploy to prod.

Suggested Solution

Change cost-category tag to be dynamically supplied based on the environment that is being deployed.

Thanks!
