serverless-demo

Current provider is AWS and some utilities were created to make the management easier.

Setup

1. Install dependencies: npm i
2. Create a .env file and populate AWS credentials. Use .env.sample as reference.

Deployment

Use deploy:dev:all when modifying the serverless.yml or the first time deployment.

Use deploy:dev:function when updating code.

Local Invocation

Function can be tested locally by running invoke:local

Remote Invocation

Test deployed function by running invoke:dev

AWS IAM permissions

In order to perform deployments a AWS account with programmatic access (Access key and Secret key) is required. A user can make deployments if they have the following policies attached.

Or add Admin access. (But probably shouldn't)

Managed

1. AWSLambdaFullAccess
2. IAMFullAccess
3. AmazonS3FullAccess
4. AmazonAPIGatewayAdministrator

Inline policies

In addition to managed, there are some inline policies attached to a user to allow cloudformation usage.

   }
