Rest API Lambda

An example of deploying AWS Lambda functions with Ansible “Deploying Amazon Lambda Functions with Ansible.” ``

Requirements

To run this, you will need:

• Python and a recent pip
• Ansible 2.5+ (pip install ansible)
• Boto, configured to work on your target AWS account (pip install boto)
• The AWS CLI (pip install awscli)

Usage

Make a new S3 bucket in your default boto region with versioning on, and update playbook.yml so the s3_bucket var has the correct bucket name, and aws_region with the region it is in, which is where the Lambda etc. will be created too.

Run ansible-playbook playbook.yml. It will create a Cloudformation stack in your AWS account called my-lambda-function.

There is two codes put.py and get.py to test Lambda. First need to add the API Gateway address to the codes.

1. collect the API Gateway address in outputs of CloudFormation "apiGatewayInvokeURL"
2. Edit put.py and get.py and replace your address in line '5': "url = '{API Gateway address}/hello/hessam'". In addition in line '6' you can change date of birth "data = {"dateOfBirth": "2000-08-25"}"
3. First run python put.py first will check if existed table's hessam in DynamoDB, if not exited, will create table and show this message: "{ "error": "DynamoDB is creating. please try again one minute later." }" after two mins again run python put.py will show "{}"
4. Second run python get.py that will show this message for example "{ "message": "Hello, hessam! your birthday is in 361 days" }"
