Description

The current way Fast Launch is supported assumes you want to enable it on all the regions you are copying the AMI to. The enable_fast_launch configuration is only at the root level of the Fast Launch configuration. There should be a way to disable Fast Launch for some regions.

Use Case(s)

An AMI that is baked is copied to multiple regions. Only one region sees heavy use and will benefit from having Fast Launch enabled. The other regions should not have to be enabled as that is a waste of resources/money.

Potential configuration

Add the enable_fast_launch boolean to the region_launch_templates array.

      "fast_launch": {
        "enable_fast_launch": "true",
        "region_launch_templates": [
          {"region": "us-east-1", "template_id": "lt-04eb90cb108a19b0b", "template_version": 6 },
          {"region": "us-west-2", "enable_fast_launch": "false" }
        ],
        "max_parallel_launches": 6,
        "target_resource_count": 5
      }

Hi @JasonLibeyTR,

Thanks for reporting this! I've just opened a PR that introduces enable_fast_launch to the region_launch_templates array, this will be rolled into an upcoming release of the plugin, but in the meantime (ideally before we merge it), may I ask you if you can test the plugin with this addition?

You'll need to compile and install it to your local environment, feel free to refer to our docs for information on that, alternatively if you have make installed, you can invoke make dev which will build and install the plugin so you can run tests with it.
