CodeDeploy How to set dynamic Capacity Provider

Question

We are deploying a set of containers into various accounts using CodePipeline and CodeDeploy. Each account has a different capacity provider name so our question is how can we set up the AppSpec.yaml file to dynamically change the Capacity Provider depending on the account? Is there an environment variable that CodeDeploy can leverage as it does the  value?
```
version: 0.0
Resources:
  - TargetService:
      Type: AWS::ECS::Service
      Properties:
        TaskDefinition: 
        LoadBalancerInfo:
          ContainerName: 'name-of-container'
          ContainerPort: 80
         CapacityProviderStrategy:
           - Base: 1
             CapacityProvider: "how-do-i-set-this-dynamically-based-on-account-or-environment"
             Weight: 1
```

Answer

Hello.

I don't think capacity providers have a placeholder like .  
Therefore, I thought that a workaround would be to use something like CodeBuild to rewrite the capacity provider name in appspec.yml during the build phase.
