Buildspec in CloudFormation template or separate buildspec.yml file?

Hi,

Whether to keep the BuildSpec directly in the CloudFormation template or to manage them as separate buildspec.yml files depends on your specific use case and team preferences.
In general, the practice followed is:

• if the BuildSpec is very small and not meant to be reused, then it is good to have it embedded.
• if the BuildSpec is complex and being reused, and requires frequent maintenance/updates, it is ideal to have it in separate files.

I have tried to summarize the difference in points to help you make an informed decision:

1. BuildSpec in CloudFormation Template:
   • Pros: Easier management, versioning tied with infrastructure.
   • Cons: Limited reusability, less visibility.
2. Separate buildspec.yml Files:
   • Pros: Better reusability, enhanced visibility, easy integration with version control tools.
   • Cons: Slightly more complex deployment, potential sync issues.

In my opinion, separate buildspec.yml files are the best, providing easier management, better extensibility, reusability, and future-proof solution.

Thanks,
