We all know that for any interview point of view the graph data structures are very much important. Because in most of the cases we end up having graph-based data structures in real-life problems. Social Graph APIs such as Facebook's Graph API, Recom...

Every one of us, at some point, would need to deploy a static website. It might be because the page is just a portfolio or a single-page JavaScript application that would not need heavy frameworks. So most of us have to host a static website, It might be with S3, Azure Blob Storage, etc. So while doing that most of us will simple copy the files to the S3 ( In my case ). Yet it might be a static website but the bugs or the correction will be there for sure. Then you have to manually replace the files with the S3. So today I will automate this whole process of S3 deploying using Github Actions. So let's get started.
You may construct custom lifecycle routines of software development straight into your Github repository via Github Actions. The workflows consist of several activities known as actions which may be carried out under specific circumstances automatically. This allows you to add continuous integration (CI), CD- and many more functions right in your repository. With that said let's get started.
Skip to Step - 2 if you already have a GitHub repo set.
Now your repository is created, So let's start uploading your own Html, CSS, Js, Images, etc. in the repository. In case you want a dummy static website for a practice copy the code from below

This repository Looks like this
Log on to your AWS account and create IAM User with programmatic access and do as following -
And Now select the Security Credentials option
And then select download options
Once the ID and key are downloaded. hold on to them. and now create an S3 Bucket from the AWS console.
I have Named my bucket SPIN, but remember that when you are creating an S3 for your domain say example.com then the S3 name must be the name of your domain. Else the CNAM from your Domain will not work
And in permissions - Bucket policy add the following code
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "PublicReadGetObject",
"Effect": "Allow",
"Principal": "*",
"Action": [
"s3:GetObject"
],
"Resource": [
"arn:aws:s3:::Bucket-Name/*" ( Replace this with your bucket name )
]
}
]
}
And then in properties of S3 Enable your Static web Hosting and give your page homepage name like Index.html
Now Get back to the GitHub repo create a File with the name .github in that folder make another folder Named workflows in that put the code below with file name
main.yml
name: Upload Website
on:
push:
branches:
- main
jobs:
iamvarshith_dev:
runs-on: ubuntu-latest
steps:
- name: Checkout
uses: actions/checkout@v1
- name: Configure AWS Credentials
uses: aws-actions/configure-aws-credentials@v1
with:
aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
# aws-region
aws-region: us-east-1( Replace with your AWS Bucket Region)
- name: Deploy static site to S3 bucket
# Your bucker name
run: aws s3 sync . s3://Bucket_name --delete
And Now find Secrets in the setting just like shown below.
And then add the AWS credentials which you have downloaded before from AWS.
Do the same with both AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY remember that the names of these variables should not be changed.
Done ! Now push any update onto the main branch and go to GitHub actions to see if there is an error. Enjoy your automatic Push upgradable AWS S3 bucket with GitHub actions.
