[FEATURE REQ] Allow to exclude global policies during extraction

[andrea-migliaccio]

Please describe the feature.

Hi,

In the "supporting independent teams" chatper in the documentation it's stated that "We envision having an operators team who will be responsible for APIM instance configurations (name/values, diagnostics settings, global policies, etc.) as well as different teams who will be exclusively focused on developing a subset of artifacts (e.g. separate apis or products)." but all the extraction includes the policy.xml of the "all apis" policies.

I don't know if this was made on purpose but in this way, we may easly have different extraction with incoherent policy.xml and the hypotetical "operators team" wuold not be the only responsible for that part.

I my opinion, there should be a way to configure (in the extractor configuration file) whenever extracting the global policies or not.

Ciao,
Andrea

For now we don't support excluding any global artifacts. In the future we envision the newly announced Azure APIM workspaces feature to take care of these specific use cases. For now you can use the gitignore file to exclude any artifacts within your repository.
