Increase service size

[gandalf.co...@gmail.com]

I've  created a new app bound to a MySQL Service.

How can I increase the standard size of 20M without modifing the configuration? Is possibile

to change size of services and apps from the cli/api ?

re mysql in particular and service instances in general:  No, you can not dynamically/programmatically change the size/configuration of a service instance.

The size/configuration of a service instance is determined by its "plan" -- for example, https://github.com/cloudfoundry/vcap/blob/master/dev_setup/cookbooks/mysql/templates/default/mysql_node.yml.erb defiines a plan called "free" with size 20 https://github.com/cloudfoundry/vcap/blob/master/dev_setup/cookbooks/mysql/attributes/default.rb#L21.

Dev_setup is hardwired with a single 'free' plan, but CloudFoundry supports an arbitrary number of plans.  The intent is that the operator of the CloudFoundry instance define a variety range of plans that are suitable for the customers/applications that will be using it.  But currently these can not be modified by customers.

So, currently, I have to choose a single plan and bind all customers to it?

CloudFoundry definitely supports as many different plans at the same time as you want: set up various service nodes that implement the various plans, and the service gateway will route provision requests to the correct node: https://github.com/cloudfoundry/vcap-services-base/blob/master/lib/base/provisioner.rb#L419

Ok, but how can I choose a plan when creating a new mysql service?

Check out this thread:

The prerelease of vmc has the '--plan' option  when creating a service:

$ vmc help create-service

Create a service

Usage: create-service [SERVICE] [NAME]

Options:

      --app, --bind APP      Application to immediately bind to

      --name NAME            Name for your instance

      --plan PLAN            Service plan

      --provider PROVIDER    Service provider

      --service SERVICE      What kind of service (e.g. redis, mysql)

      --version VERSION      Service version

I have to use the latest vmc version for this option?

Will be possible to change a plan in an active service? 

[Glenn Oppegard]

Yes, you have to use the latest vmc for that option. I'm not sure if you can change the plan of an active service. Perhaps Nick or Alex can speak to that.

[Nicholas Kushmerick]

No, you can't change a service instance's plan.  However, the snapshot APIs allow you to copy the data from an instance of plan A to a different instance of plan B: https://github.com/cloudfoundry/cloud_controller/blob/master/cloud_controller/config/routes.rb#L58-69
See also https://github.com/cloudfoundry/vcap-yeti/tree/master/spec/service_lifecycle for concrete examples of how to call these APIs.
