How to create EC2 Credentials

So that you can also access your S3 bucket’s outside of OpenStack (Swift), you have to create so-called EC2 credentials. This is currently only possible via CSC, which is described below.

List, create, Swift/S3 credentials

Note

The parameters –user and –project are optional

Prerequisites

• Basic knowledge of the Linux operating system (shell)
• Access to a running Linux VM with configured OpenStack Client (see setup OSC)

The steps to be taken are:

1.) list and check existing ec2 credentials

#list the existing ec2 credentials
openstack ec2 credentials list

2.) create new ec2 credentials

openstack ec2 credentials create

3.) list new ec2 credentials

openstack ec2 credentials list

How to delete EC2 Credentials

To delete one or more EC2 credentials, use the following command.

usage: openstack ec2 credentials delete [-h] [--user <user>]
                                     [--user-domain <user-domain>]
                                     <access-key> [<access-key> ...]

# Example
