[Discuss] Update Autoscaling/Deployment Policies in Runtime

[Imesh Gunaratne <im...@apache.org>]

Hi All,

We have now implemented a new feature to allow users to update Autoscaling
and Deployment policies in runtime.

This feature is exposed via the REST API and the CLI has been updated with
two new commands:

update-autoscaling-policy -p <policy-file-path>
update-deployment-policy -p <policy-file-path>

Thanks

AFAIU the scope of a subscription is a tenant user, not a tenant, with the
new user mgt model. However, handling policies for subscriptions as you
suggested above will solve this AFAIU.

@Isuru: What I meant by "managing policies against subscriptions" is that
creating a copy of the selected policy for the subscrription and persist it
against the subscription. As a result the tenant who made this subscription
can update the policy without affecting the other subscriptions which are
using the same policy.

Is any meaning to do this against users because the scope of a cartridge
subscription is its tenant. Within a tenant many users should be able to
manage their policies. May be we can introduce a secuity role to handle
this.

Hi,

+1 for manage policies against users.

Or else we can manage policies against users, so that one user updating the
policy will not have any affect on another user.

A good point, we might need to manage policies against the subscriptions to
do this.
I think we will also need to have the ability to update global policies.

Hi Imesh,

Do we allow policies which are in use to be updated?
My concern is say a user subscribe with a policy, is he affected if another
user update policies later?



Touched, not typed. Erroneous words are a feature, not a typo.
