How to implement S3 using Rails?

gem "aws-sdk-s3", require: fals bundle install

  • Create an account on AWS if you haven’t registered on AWS.
  • Get the access_id, secret_key_id of the AWS account if already registered from the IAM section after logging into the AWS console.

gem "aws-sdk-s3", require: false

aws:
access_key_id: ACCESS_KEY_ID
secret_access_key: SECRET_ACCESS_KEY

  • Log in to the AWS console.

Add the region and bucket name in the credentials.yml as shown below;

EDITOR=nano rails credentials:edit
aws:
access_key_id: ACCESS_KEY_ID
secret_access_key: SECRET_ACCESS_KEY
region: REGION_NAME
bucket: BUCKET_NAME

Note: You can find out the region name in the URL, region as a query parameter in the address bar of the browser.
