Deploy_plan workflow should skip create_swift_rings_backup_plan task unless swift service is deployed

[Martin André]

Currently the create_swift_rings_backup_plan task runs unconditionally in the deploy_plan workflow, whether or not swift service is deployed.

https://github.com/openstack/tripleo-common/blob/83c5cd1f7cf0ecc2160b6e27e624470ff8d5c4c9/workbooks/deployment.yaml#L161-L168

There are probably other tasks that are executed when there is no need to. This can potentially slow down the deployment by tens of seconds if not minutes.

We need a way to know from the mistral workflow, the list of services that are being deployed, and skip unneeded tasks.

One possibility (to be confirmed) would be to make use of the tripleo.parameters.update action which does a heat validate call. This should retrieve the *Services parameter values for all roles, and store a list of the enabled services.

Is this still an issue?

[Martin André (mandre)]

Yes, this task is still run unconditionally, causing the deployment to take longer than needed in scenarios where swift isn't deployed -- tripleo deploying openshift for instance.

This is an automated action. Bug status has been set to 'Incomplete' and target milestone has been removed due to inactivity. If you disagree please re-set these values and reach out to us on freenode #tripleo
