“ I have checked the documents of AWS to automate the experience of lambda versioning with change in configuration and code. I have checked for AWS code pipeline service which makes the process easy and automates for everyone. The Pricing of Code pipeline is based on when the pipeline runs. Also price for code build. ”
A keyword define "Devtron" play an important role in sorting the complexity of DevOps, AppOps and Kubernetes. Also "GitHub" helps to integrate and automate. Both Devtron and GitHub is an open source one.
In this post, you will experience the automation of lambda versioning with configuration and code change using cloudformation and code pipeline. Here I have created a code pipeline to automate lambda creation and its versioning with change in set parameters using cloud formation with artifacts to be stored in s3 bucket.
Prerequisites
You’ll need a Github account and git installed on a local machine. You’ll need AWS CLI installed and configured on your local machine.
Architecture Overview
The architecture diagram shows the overall deployment architecture with data flow, code build, code deploy, code pipeline, s3, sns, cloud formation, lambda.
Solution overview
The blog post consists of the following phases:
- Create of IAM Role, S3 Bucket, Buildspec.yml, Template.yaml and Sample HelloWorld.js File
- Create of CodePipeline and Build Project
- Create SNS Topic with Subscription and Check of CloudFormation with Lambda Creation
- Testing of Lambda Configuration Parameters and Code Deploy while Updating in GitHub
Phase 1: Create of IAM Role, S3 Bucket, Buildspec.yml, Template.yaml and Sample HelloWorld.js File
- Open the IAM Console and create a role for cloudformation with AWS lambda execute policy and inline policy with required permission. Create an S3 bucket named as lambda-ci-cd-demo-test. Also configure buildspec.yml file, template.yaml file and helloworld.js file as per the requirement to build a lambda code and configuration part.
Phase 2: Create of CodePipeline and Build Project
- Open codepipeline console and create a pipeline with source as github and provider as cloudformation with default IAM role and custom s3 inline policy to be attached with the role. Also build a project with custom settings.
Phase 3: Create SNS Topic with Subscription and Check of CloudFormation with Lambda Creation
- Open the Amazon Simple Notification Service and create a topic with subscription for approval notification in the code pipeline. In the code pipeline the stages as source, build, deploy as createchangeset, approvechangeset, executechangeset.
Phase 4: Testing of Lambda Configuration Parameters and Code Deploy while Updating in GitHub
- Test the lambda configuration and code in doing changes on various parameters in github.
Clean-up
Delete Code Pipeline, Code Build, IAM Role, S3 Bucket, Cloud Formation, SNS.
Pricing
I review the pricing and estimated cost of this example.
Cost of Code Build = $0.0
Cost of Lambda = $0.0
Cost of Simple Notification Service = $0.0
Cost of Simple Storage Service = $1.0
Total Cost = $(0.0 + 0.0 + 0.0 + 1.0) = $1.0
