When working with the AWS Serverless Application Model (SAM), have you ever found yourself wondering if there’s a way to translate your SAM template into a CloudFormation script before deployment? Imagine having the power to cross-check and verify every component SAM is going to create automatically, right from your local machine. The good news is—you can do exactly that!
Why Translate SAM to CloudFormation?
Translating your SAM template into a CloudFormation script locally gives you peace of mind. You can review and understand the infrastructure changes before they’re deployed, reducing the chances of unexpected surprises. This is especially helpful for complex templates where even small changes can have significant impacts.
Getting Started: Install SAM CLI
To get started, make sure you have the SAM CLI installed. If you haven’t already done so, you can download it from the official AWS installer.
Once installed, confirm it’s correctly set up in your IntelliJ IDE by running the command:
sam --version
If everything is set up correctly, you should see the version of SAM CLI installed.
How to Translate SAM Template to CloudFormation Script
Navigate to Your SAM Template Directory:
Open your terminal and navigate to the directory where your template.yaml the file is located.
Run the Validation Command:
Execute the next command to translate your SAM template into a CloudFormation script:
sam validate -t template.yaml --debug
Troubleshooting: Default Validation Parameters:
In some cases, particularly with the “Hello World” example in IntelliJ, you do not get the translated template at once due to default.validate.parameters. If this happens, simply delete or comment out these parameters in your template.
After making the necessary adjustments, run the command again:
sam validate -t template.yaml --debug
You should now see the translated CloudFormation script.
Benefits of Local Translation
By following these steps, you can safely and confidently translate all of your SAM templates into CloudFormation scripts before deploying them to AWS. This approach allows you to see the potential impact of your SAM template changes and gain a deeper understanding of your infrastructure setup.
Conclusion
Having this level of control and insight is invaluable, especially as you scale your serverless applications. So next time you’re about to deploy, take a moment to translate your SAM template first—you’ll thank yourself later!
