Describe the bug

E3048 '4 vCPU' is not one of ['256', '512', '1024', '2048', '4096', '8192', '16384']

See:

The number of CPU units used by the task. It can be expressed as an integer using CPU units (for example, 1024) or as a string using vCPUs (for example, 1 vCPU or 1 vcpu) in a task definition. String values are converted to an integer indicating the CPU units when the task definition is registered.

I'll have a PR very shortly. Just testing a few things out to make sure I have it.

Sounds great. Thanks for the prompt response and for your work.

A lot of variations to whats in the documentation....

.25 vCpU as many spaces as you need and vcpu is case insensitive. I've updated the schema to handle this.
Same applies to memory
1GB works along with 1 gb

Switching to a pattern style validation for this validation.

This should be available in v1.8.0 @Slooz
