Description John Fulton 2019-10-29 17:41:49 UTC

A process is documented upstream [1] to extract configuration from the control plane overcloud into multiple files to be used as input to subsequent DCN overcloud deployments. This BZ tracks having tripleo-client provide a command to perform the extraction so that the user doesn't have to follow as many steps (though both processes should be supported).

Benefits of providing one command to do this include avoiding bugs like bz 1762360 and simplifying operator experience.

Implementation of this change could be a variation of https://review.opendev.org/#/c/672070

We should be able to pass routed network information between split control plane deployments by using the following parameters:

 https://opendev.org/openstack/tripleo-heat-templates/src/branch/master/network_data.yaml#L12-L23

It would be useful if generating input for the above were in scope with this RFE.

According to our records, this should be resolved by python-tripleoclient-12.3.2-0.20200130192329.78ac810.el8ost.  This build is available now.
