SysEleven OpenStack Cloud - Floating IPs
Concepts
Floating IPs allow internal resources to be accessed from external networks by assigning a public IP address to instances or routers.
List Floating IPs
To get a list of all Floating IPs in a region you can click on the Floating IPs icon in the sidebar.
The list provides an overview of all floating IPs in your environment.
Each row displays details about the associated resource, and you can access more information by clicking on the name or ID of the resource.
Additionally, you can perform actions for a floating IP by clicking the option at the very end of a table row. This will pop up a menu with common actions to perform on a floating IP.

Floating IP Actions
Info
The action menu change with its status: it offers Dissociate Floating IP if the IP is already associated, or Associate Floating IP if it is not.
Associate Floating IP
To initiate the association, click the option next to the floating IP in the list.
This opens a prompt where you can select the port to associate with the floating IP.
If no ports are available for selection, you will need to create a port in the network section before proceeding.
Usage
openstack floating ip set
[--port <port>]
[--fixed-ip-address <ip-address>]
[--description <description>]
[--qos-policy <qos-policy> | --no-qos-policy]
[--tag <tag>]

Example
Dissociate Floating IP
To dissociate the floating IP, click the option next to it in the list.
A prompt will appear, where you can confirm the action by clicking DISSOCIATE IP.

openstack floating ip unset
[--port]
[--qos-policy]
[--tag <tag> | --all-tag]
<floating-ip>

Example
Release Floating IP
Releasing a floating IP is straightforward.
Use the menu in the list of floating IPs and select the Delete option.
In the emerging prompt confirm the deletion by clicking Delete .
Tip
Before deleting a floating IP, it is advisable to disassociate it from any resources. While the system may allow deletion even when the IP is associated, disassociating the IP first helps prevent potential issues or conflicts.
Usage
openstack floating ip delete <floating-ip> [<floating-ip> ...]
<floating-ip>- Floating IP(s) to delete (IP address or ID)
