May 2, 2018 · AWS SAM (Serverless Application Model) is an abstraction layer that simplifies defining and deploying serverless applications on AWS. It is purpose-built for serverless computing and focuses on resources like Lambda functions and API Gateway. SAM uses easier to write templates and provides local testing capabilities.

Here’s a comprehensive solution to use environment-specific variables with AWS SAM. Do not use this approach for secrets! In the Cloudformation template (template.yaml by default), define the variables and refer to them as needed, for example:

I'm using AWS SAM in Visual Studio Code to set up a number of Node.js lambda functions. I am using Windows 10. I'm only starting out with AWS SAM and I've generated the Sample Hello World App using the Command Palette and it works.

Aug 18, 2021 · Is it as simple as deploying a new stack with a new name like sam deploy —stack-name my-app-staging and sam deploy —stack-name my-app-production? In the following example, I have one question. If my SAM template contains a Parameters with the name MyEnvironment that has three possible values, how does the deploy know which value of the ...

May 2, 2019 · I have just started using AWS serverless using SAM and have run into the problem below: SAM invoke can't seem to find a python module that my lambda handler is importing but I can otherwise import that module. The structure of my project is: root-dir/ mymodulename/ mymodule.py; aws/ sam/ template.yaml; packaged.yaml; myawsservice/ app.py; test ...

The reason this works is because the sam deploy command automagically picks up the compiled template.yaml in the .aws-sam directory, which is created by running sam build. If you inspect this generated template.yaml you'll see that the lambda references a directory within .aws-sam that contains the code and all of its dependencies. –

Working through a deployment on a stack using AWS SAM and deploying via GitHub actions and was trying to use the Config TOML file and specifying a config environment in the deploy command and I am running into the issue where it seems to be just ignoring what I am specifying in the deployment command.

Followed the instructions here to install sam-cli on Windows Subsystem for Linux (Ubuntu) $ brew tap aws/tap Updating Homebrew...

Mar 5, 2020 · This issue mentions that nested stacks can't use transforms like SAM, and in this closed GitHub issue, one of the maintainers of the AWS SAM CLI noted "Closing as we don't yet support Nested Templates in SAM build or any other commands except package. We should create a general issue for this support."

sam deploy --guided --capabilities CAPABILITY_IAM CAPABILITY_AUTO_EXPAND The same applies to providing multiple values for --notification-arns and --tags as well. I'm not sure why the AWS SAM CLI developers decided to implement it this way, but they expect a whitespace-separated list of values for these parameters.
