An example command to create a security group called My_Wiki_SG

Create and manage Security Group rules
You can modify Security Group rules with the openstack security group rule command.
Create new rules for a group
Allow access from all IP addresses (specified as IP subnet 0.0.0.0/0 in CIDR notation) for the port 8080
The command and response looks like the following
openstack security group rule create --proto tcp --dst-port 8080 339bd140-e6a0-4afd-9b24-029c3243e779

Locate the Security Group that you wish to remove a rule from and take note of its ID
Note
For this example we are using 339bd140-e6a0-4afd-9b24-029c3243e779
Running the following command will return all rules associated with that security group.
+--------------------------------------+-------------+-----------+-----------+------------+-----------+-----------------------+----------------------+
| ID | IP Protocol | Ethertype | IP Range | Port Range | Direction | Remote Security Group | Remote Address Group |
+--------------------------------------+-------------+-----------+-----------+------------+-----------+-----------------------+----------------------+
| b0f0edd2-7a55-44b4-84a8-9650de36a7ec | None | IPv6 | ::/0 | | egress | None | None |
| f0bce470-8d94-453f-9dfa-3e3e34b0c80e | tcp | IPv4 | 0.0.0.0/0 | 8080:8080 | ingress | None | None |
| f3925a01-5d47-4c55-ac73-1647cca5b739 | None | IPv4 | 0.0.0.0/0 | | egress | None | None |
+--------------------------------------+-------------+-----------+-----------+------------+-----------+-----------------------+----------------------+
Take note of the Security Group Rule ID
Note
For this example we will use f0bce470-8d94-453f-9dfa-3e3e34b0c80e
To delete a rule, run the following command with the correct rule ID.
Re-run the list command to confirm the rule has been deleted
+--------------------------------------+-------------+-----------+-----------+------------+-----------+-----------------------+----------------------+
| ID | IP Protocol | Ethertype | IP Range | Port Range | Direction | Remote Security Group | Remote Address Group |
+--------------------------------------+-------------+-----------+-----------+------------+-----------+-----------------------+----------------------+
