Basically LaunchTemplateOverrides for L2 construct is missing the InstanceRequirements attribute.

If you specify InstanceRequirements, you can't specify InstanceType.

@wafuwafu13 please add an integration test or update an existing one

lpizzinidev

Thanks for starting this.
This is still a work in progress as the property needs to be implemented in the L2 construct directly.
Also, the related documentation, unit, and integration tests are required as this is a new feature.

We'll need to implement the interface in the L2 construct and not make use of the existing one from L1.

Do you mean I should define instanceRequirements in another place?
If so, I would be grateful if you could tell me where to define it.

Nevermind, I got it wrong.

✅ Updated pull request passes all PRLinter validations. Dismissing previous PRLinter review.

lpizzinidev

Thanks 👍
I think we should require one of instanceType or instanceRequirements to be specified, feel free to comment if you think otherwise.
