Updating min number of cartridge instances (partitionMin)..?

Hi people,

Let’s say I’ve deployed a service using Stratos, and now I want to increase the minimum number of instances that should be active at a given point in time. How can I do that without unsubscribing them all (thus killing the service)?

I was looking through the API docs for 4.0 and 4.1 (CLI and REST), and didn’t see anything for updating or even deleting policies (and I don’t think it’s possible to update subscriptions without killing the cartridges either)...

Best regards,

Michiel

Hi,

Ok, I look forward to that in 4.1.0! Thank you very much!

Hi Michiel,

As Udara mentioned this is not supported in released 4.0 version. We will
add the capability to change min and max in next 4.1.0 release. Docs will
be updated for 4.1.0.

Thanks.

Hi,

I'm afraid manual scaling is not yet supported in Stratos. Instances count
is increased by Auto Scaler in case of scaling up. It is done automatically
according to requests in flight count of LB, instance memory consumption
and CPU load of instances. Please refer to [1] for a blog post about
scaling in Stratos.

There is already a jira to manual scaling up.
