How do I scale up and down an Elastic Beanstalk application via command line without set the desired instance number

Question

I am new on AWS Elastic Beanstalk and I have deployed an application via eb cli. For me scale up or down my application via eb cli I have found the following command

eb scale number-of-instances

but in my scenario I would like to scape up or down only once instance per time.

What I am looking for is a way to scale it by using its cli with some command like

eb scale up/down 

but this kind of command is not supported.

Is there a way in which I am able to scale my application this way via eb cli, or I must always set the number of instances that I want?

Answer 1

I have solved this problem by getting the instance number via

eb status - v

and than based on the value of Running instances I execute the command

eb scale number-of-instances

I know that this is not the best solution, but this is how I solved my issue
