Collection of some scripts to automate AWS Lambda deployments

AWSDeployer

Collection of some scripts to automate AWS Lambda deployments. They are useful for quick development and deployment of AWS Lambda functions and layers, as well as a REST API Gateway integration.

Just set your working directory, your awsdeployer configs and you should be good to focus on actual development.

Currently only supporting Python lambda functions.

Lambda Deployer

Easily deploy Lambda functions and their layers.

Usage

These scripts assume a working directory like that of sample_lambda:

• awsdeployer.ini file with your secrets (see sample file)
• awsdeployer_lambda.json with your layer and function configurations
• function_name.py files, one for each of your Lambda functions

The executable is lambda, which accepts the following commands:

• $ lambda layer <layer-name>: deploy layer "layer-name" into AWS
• $ lambda config [<function-name>]: update all function configs in AWS (specify a function name to only update that function's configs); non-existing functions are created (default Lambda IAM permissions)
• $ lambda <function-name>: if no option above is matched, the specified function has its code and configs updated (probably the most common case); non-existing functions are created (default Lambda IAM permissions)

Tip: all parameters can be replaced by a shorthand, which you can specify in your awsdeployer_lambda.json.

Configs

• main_file: specify the main function file (if not present, function_name.py is assumed)
• additional_files: additional files to include with the main function file in the deployment

API Gateway Deployer

Easily deploy API gateway, handling input parameters and error codes, so you can focus on the code.

Usage

These scripts assume a working directory like that of sample_apigateway:

• awsdeployer.ini file with your secrets (see sample file)
• awsdeployer_api.json with your API definition in JSON (NOT nested!)
• function_xxxx.py files, one for each of your Lambda functions associated with the endpoints

The apigateway executable accepts two commands:

• $ apigateway all: deploy the full API (destroys already existing ones)
• $ apigateway <method> <path>: deploy a single method (also destroys already existing ones)

The script also helps automating HTTP error codes, which you can find in status_codes.md. They are automatically deployed into API Gateway and caught by it, as long as you import the awsdeployer package, as seen in sample_apigateway/get.py.
