Enable autoscaling only for one environment

[David Beja]

Hi,

Is it possible to enable autoscaling only for prod?
What would be the best way to achieve that?

Thanks!

Great idea! The plugin does not support anything like this currently, but maybe you can somehow do this with Reference Variables in Javascript Files

Thanks!

The way I did this was to keep the autoscaling for all environments but with lower values to all environments except prod:

custom:
  maxRead_prod: 2000
  maxWrite_prod: 1000
  capacities:
    - table: users
      read:
        minimum: 5
        maximum: ${self:custom.maxRead_${self:provider.stage}, '10'}
      write:
        minimum: 5
        maximum: ${self:custom.maxRead_${self:provider.stage}, '10'}

Hi,

just wanted to do the same thing but for me the nested variable replacement did not work (I got null in the generated template) so I had to write

maximum: ${self.custom.maxRead_prod}

Any idea why?

[David Beja]

Do you have the stage defined on provider with a custom value?

provider:
  name: aws
  runtime: nodejs6.10
  stage: ${opt:stage, 'dev'}

Ok, I was using serverless 1.18.0, I updated to 1.24.1 and now it works.

Just stumbled upon this and would like to point out that @dbeja is using the maxRead_ custom variable for both reads and writes. His serverless.yml file should contain the following.

custom:
  maxRead_prod: 2000
  maxWrite_prod: 1000
  capacities:
    - table: users
      read:
        minimum: 5
        maximum: ${self:custom.maxRead_${self:provider.stage}, '10'}
      write:
        minimum: 5
        maximum: ${self:custom.maxWrite_${self:provider.stage}, '10'}
