Managing Security Groups
Security groups are sets of IP filter rules that are applied to all project instances which define networking access to the instance.
On the Project tab, open the Network tab and click Security Groups category.
Creating Security Groups

- Click Delete Security Groups on the right (red colored button)
- Confirm deletion of identified Security Groups by clicking Delete Security Groups.
Managing Floating IPs
A floating IP is an IP address that a project can associate with a VM so that the instance has the same public IP address each time that it boots. Users can create a pool of floating IP addresses and assign them to instances as they are launched to maintain a consistent IP address for maintaining DNS assignment.
On the Project tab, open the Network tab and click Floating IPs category
Creating and Associating Floating IPs
- Click the Allocate IP to Project button
- Click Allocate IP
Linking Floating IPs to instances
- Click the Associate button on the right
- Fill out the required fields:
- IP Address: List of available Public IP reserved to your project
- Port to be associated: IP address of the interface on the selected instance
- Click Associate
Unlinking Floating IPs to instances
- Tick the box on the left of the floating IP/s to be unlinked
- Click the Release Floating IPs button
- Click Release Floating IPs
Creating Containers
A container organizes and stores objects in Object Storage. The concept is similar to the concept of a Linux directory, but cannot be nested. A container is an alternative for an Image service container format.
To start creating containers:
- Click the + Container button
- Fill out the required fields:
- Container Name: Specify name to identify container
- Container Access: Access level (either private or public)
- Click Submit
Uploading Objects
- Click Upload Icon on the Object Store category under selected container
- Fill out the required fields:
- File: File to be uploaded from your machine
- File Name: Specify name to identify object
- Click Upload File
Deleting objects
- Tick the box on the left side of the object to be deleted in the chosen container
- Click the Trash icon
- Click Delete
Deleting Containers
- Select the container then click the Trash icon
- Click Delete to confirm deletion of container
