How to Build Java app on Github actions and deploy to S3 bucket

 

Step 1: Manually creating and deploying a Next.js project to a new S3 Bucket

To get started with our new S3 Bucket, first log in to your AWS account and navigate to the S3 service.

We’ll want to create a new bucket, using the name of our choice, which will be used for the S3 endpoint where our website is hosted. We’ll also want to configure our S3 bucket to be able to host a website.

Choose a bucket name of your choice

Also choose ACL enable

Uncheck the block all public access

Then click Create Bucket

After Bucket is created navigate to the bucket properties and click on properties. scroll al the way down and click on edit static web hosting

Then click enable

leave the option as host static website and in the index document type index.html

then click save changes.

then go to permission to edit the bucket policy with this code

{

    "Version": "2012-10-17",

    "Statement": [

        {

            "Sid": "PublicReadGetObject",

            "Effect": "Allow",

            "Principal": "*",

            "Action": "s3:GetObject",

            "Resource": "arn:aws:s3:::BUCKETNAME/*"

        }

    ]

}

scroll down to the access control list and edit it to look like this 

 

After setting this go over to your github repository and create a new repo and in the new repo copy the folders you would like to build into the repository like we did in the previous classes and create a folder in the repository  called .github/workflows 

then in that folder create a file called deploy.yml and paste this code inside there

This code will help you run the package and deploys it into s3 bucket and you can view the static site with the link in the bucket.

The next step will be to add credentials to Github as secrets

Go to your Github repository -> settings -> secrets -> actions

Add new repository secret

Need to add two secrets: AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY (Secret access key) which will be used later in the workflow

Add AWS_SECRET  and also default region too in the same way.

Note: in the repository you have to add you AWS keys. This can be generated in the IAM console and you will input it in the repository settings.
