ocata heat devstack plugin checking out heat master

It looks like you're missing or have an old version of oslo.policy. The DocumentedRuleDefault object was added to oslo.policy in version 1.29.

I recommend retrying you're installation once you have an updated version of oslo.policy.

This error still exists in oslo.policy v1.18.0 while building devstack stable/ocata on ubuntu 16.04.3

Here is the error:

Eventhough I did upgrade oslo.policy to v1.33.1, still I'm getting error becuase /opt/stack/requirements/upper-constraints.txt file got oslo.policy===1.18.0, So its re-installing oslo.ploicy to v1.18.0 from v1.33.1

I tried updating file /opt/stack/requirements/upper-constraints.txt with oslo.policy===1.33.1 and ran ./stack.sh, still getting the same error.

Is this something with heat/oslo.policy then?

yes @Gage Hugo

Ubuntu 16.04.3 LTS, the latest supported version of oslo.polcy is 1.18.0.

stack@arunx:~/devstack$ pip show oslo.policy

Requires: six, requests, stevedore, oslo.serialization, PyYAML, oslo.config, oslo.i18n

This issue is preventing HEAT service is not being able to build for devstack-stable/ocata release. Hence only

Had an engineer run into this while using ocata devstack + heat, will look into further.

I was able to duplicate this, it seems like there may be an issue with the heat devstack plugin, when running devstack (stable/ocata) it originally checks out stable/ocata heat, but once it hits the devstack plugin it will checkout master heat, and then hit:

Looks like the policies modules were added after ocata:
