How to access S3 resource from internet?

To access an S3 bucket resource from the internet, you need to configure your S3 bucket settings and access policies correctly. Here’s a step-by-step guide to make your S3 objects publicly accessible from the internet:

1. Create or Select an S3 Bucket

• If you don’t have an S3 bucket, first create one by navigating to S3 in your AWS Management Console and clicking Create Bucket.
• Provide a name, choose a region, and leave the rest of the settings as default (unless you have specific requirements).

2. Upload the Object to the S3 Bucket

• Once your bucket is created, upload the files (e.g., images, documents, etc.) that you want to make publicly accessible.
• You can do this by selecting the bucket, clicking Upload, and following the steps to upload the file.

3. Make the Bucket or Object Public

By default, S3 buckets and objects are private. To allow public access, you can change the bucket or object’s access policy.

Make the Entire Bucket Public:

1. Go to Permissions in the S3 console for the bucket.
2. Scroll down to Block Public Access (Bucket Settings) and click Edit.
3. Disable the options that block public access. This allows public access to be enabled at the bucket or object level.
4. Save the changes.

Update the Bucket Policy:

-- Scroll down to Bucket Policy under the Permissions tab.

-- Paste a policy that allows public read access to the bucket.

-- Replace YOUR-BUCKET-NAME with your actual bucket name.

-- Save the changes.

Make a Specific Object Public:

1. Navigate to the object you want to make public inside your bucket.
2. Select the object and click Actions → Make public.
3. Confirm the action.

4. Access the Object via URL

• Once the object is public, you can access it through a URL.
• The URL format will be:

https://my-bucket.s3.amazonaws.com/image.png

5. Ensure Correct Permissions

To further refine your security while making resources accessible from the internet, consider:

• Using IAM policies to restrict who can make changes to your S3 bucket.
• Implementing bucket access logging to track who is accessing your files.
• Using a CDN like AWS CloudFront to cache and securely serve your S3 content over HTTPS.

This setup should allow you to serve S3 content publicly over the internet.
