Create and Deploy Lambda Functions in few minutes
First you need to install serverless:
npm install -g serverless
Create a directory folder for your template
mkdir lambda-minutes
Setup the serverless template for node.js
serverless create -t aws-nodejs
Clean up the boilerplate config from the serverless.yml and copy the simple config below: (Sydney region)
service: lambda-minutes
provider:
name: aws
runtime: nodejs6.10
stage: dev
region: ap-southeast-2
functions:
hello:
handler: handler.hello
events:
- http:
path: /
method: get
There are better ways to setup security, like creating IAM User with limited permissions, but for this example, we will get the key and secret from security credentials.
Login to AWS => My Security Credentials
Copy the Access Key and Secret Access key and setup the following:
serverless config credentials --provider aws --key xxx --secret xxxx
Add the flag -o to override if you want to replace your existing credentials.
Deploy your lambda function in dev environment
serverless deploy
Deploy your lambda function in production
serverless deploy --stage production
