Create a s3 bucket in a certain region and replace aws-codedeploy to the name of the bucket you created. Replace us-east-1 with the name of the region of your ec2 instance and s3 bucket. You can run the command as a bash script or manually in ubuntu instance terminal. ANY OF THE BELOW COMMAND WOULD WORK.
