AWS CLI Copy from Bucket – An error occurred (AccessDenied) when calling the CopyObject operation: Access Denied

Hi everyone,

I ran into the following error while trying to copy files from one bucket to another using the AWS CLI:

An error occurred (AccessDenied) when calling the CopyObject operation: Access Denied

Thankfully this one is pretty self-explanatory. My user was missing the permissions required to view the bucket.

To see your user: aws configure list
To add permissions: view the IAM Management Console



AWS CLI Copy to Bucket – Could not connect to the endpoint URL

Hi everyone,

I ran into the following error while attempting to copy files to a bucket via the AWS CLI:

The solution turned out to be pretty straight-forward. The region on the cli-config was set incorrectly. For example, mine was set to “Sydney” instead of “ap-southeast-2”. Type “aws configure list” to check what yours is set to.

Unable to Access RDS Database from Elastic Beanstalk Application

Hey everyone,

I ran into a bit of an issue today where I was unable to access my RDS SQL Express instance from my .NET Elastic Beanstalk instance. I was receiving the following error:

The server was not found or was not accessible.

The solution turned out to be fairly simply thanks to this StackOverflow post: http://stackoverflow.com/a/33207022/522859

Get your server instance security group:
– Log into AWS
– Navigate to elastic beanstalk
– Open your application instance
– Open configuration
– Open instances
– Find “server” on the page and copy the value in the “EC2 security groups” field

Add your server instance security group to your rds rules:
– Navigate to the RDS Dashboard
– Open your RDS instance
– Click on view details (left hand side or top)
– Find Security and Network
– Click on the rds-launch-wizard under security groups
– Click on inbound rules (very bottom currently)
– Add a new inbound rule with the copied security group as the source
