Fargate doesn't support spot pricing for ARM architecture
"errorMessage": "FARGATE_SPOT capacity provider is not supported when using ARM architecture.",
Are you currently working around this issue? How are you currently solving this problem?
Using on-demand at the moment but will probably switch back to non-arm arch if it works out advantageous from a pricing perspective (that parts harder to quantify).

@ChrisMcKee this should be possible using CapacityProviderStrategy already. Am I missing something?

@vibhav-ag Changed the title/description its the lack of support for spot pricing on graviton. Though the API has a bit to be desired as you can set capacity providers on a cloudwatch event target and there's no introspection to check if those exist on the cluster till runtime. Similarly you can have a capacity strategy for spot, the ecs target takes the arn of the task but it doesn't validate if the configuration could run till runtime.
