Examples for AWS CloudFormation templates. Currently focused on templates for AWS Serverless Application Model (SAM).
- All examples contain a
deploy.shfile which contains some steps to package the source code and deploy a CloudFormation stack. Each file expects that you set aLAMBDA_BUCKETvariable. Just enter a S3 bucket name where you have access to. It will be used to upload the code zips for your Lambdas. - Finally, just open your command line and execute
$ ./deploy.shin the desired folder. Alternatively, you can use$ export LAMBDA_BUCKET=<your-bucket-name> && ./deploy.sh. - Test it!

-
AWS Lambda: Policies: Creates multiple Lambda functions and gives them the permission to use CloudWatch logs using different approaches.
-
AWS Lambda: Register to Kinesis Creates a Kinesis stream. Also deploys one Lambda function which is sending data to the stream and two functions which are reading from the stream.
-
AWS Lambda: Register to S3 updates This example creates an S3 bucket and a Lambda function. The Lambda function is configured to be called when a new file is uploaded to S3.
-
AWS Lambda: Register to SNS topic Registers a Lambda function to listen to SNS topic updates.
-
AWS Lambda: Scheduled Functions Creates two Lambda functions which are triggered every day using different syntax.
-
AWS Lambda: Serverless Apis Declares a simple AWS Lambda function using SAM.
-
CloudFormation: AWS::Include If a CloudFormation stack grows bigger and bigger, you might face an error like
at 'templateBody' failed to satisfy constraint: Member must have length less than or equal to 51200which simply means: your CloudFormation template is too big and you have to split it. I also wrote a blog post about two options you have in order to reduce your CloudFormation template size. In this example, I've added the code for using AWS::Include command. -
CloudFormation: Environments This example shows how to create parameterized stacks, so e.g. you can create different environments of your stack. The same resources are created with different names and belong to a different stack.
-
CloudFormation: Intrinsic Functions Not an actual template, but it's showing some examples of intrinsic functions.
