createNodeGroup

on a

eks.Cluster

takes an

instanceType

parameter which must be a

aws.ec2.InstanceType

. I'd like to pass in a string from a config file. How can I do this without Typescript complaining?

If the string is in a variable named, say,

instanceType

, you would say either

createNodeGroup(..., instanceType as aws.ec2.InstanceType, ...)

or

createNodeGroup(..., <aws.ec2.InstanceType>instanceType, ...)

. This simply asserts the type, it doesn't actually check that it's a valid instance type. More info here https://www.typescriptlang.org/docs/handbook/basic-types.html#type-assertions.

Yep, that does it. Thank you!
