Create and manage network via CLI
Note
The openstack CLI will need to be setup to interact with the FlexiHPC system. Please read Setting up your CLI environment to interact with FlexiHPC to get started.
Create a network¶
Running the below command will generate a network without a subnet

Take note of the id that is returned for the new network
Note
Our id from above is 15274353-ceae-476c-a374-dc7142a676f4
Create a network subnet¶
Running the below command will generate a subnet for the network that you supply the id from
Our example command using the id from above will look like the following
openstack subnet create wiki-subnet --network 15274353-ceae-476c-a374-dc7142a676f4 --subnet-range 192.0.2.0/24

Running the below will list all subnets within your project
+--------------------------------------+--------------------+--------------------------------------+------------------+

Delete a subnet¶
Run the below command to list out all subnets
+--------------------------------------+--------------------+--------------------------------------+------------------+
| ID | Name | Network | Subnet |
+--------------------------------------+--------------------+--------------------------------------+------------------+
| 5c2644ad-7253-42f5-ad69-40970b84dea6 | external | 33d0c11b-b659-4b77-9afc-5676fe965839 | 163.7.177.0/24 |

+--------------------------------------+--------------------+--------------------------------------+------------------+
Take note of the subnet id that you wish to delete
Note
For our example we will use ae9277e7-0a2c-4325-8eb1-33ad86eec974
We then run the following command while supplying it with the id we have chosen to delete
The server will not give a response if successful so you will need to run openstack subnet list to confirm its removal
Using our example id our command and list looks like the following
+--------------------------------------+--------------------+--------------------------------------+------------------+
| ID | Name | Network | Subnet |
+--------------------------------------+--------------------+--------------------------------------+------------------+
| 5c2644ad-7253-42f5-ad69-40970b84dea6 | external | 33d0c11b-b659-4b77-9afc-5676fe965839 | 163.7.177.0/24 |

Delete a network¶
Run the below command to list all networks
+--------------------------------------+--------------------------------+--------------------------------------+

Take note of the network id we want to remove
Note
For our example we will use 15274353-ceae-476c-a374-dc7142a676f4
Then run the below command while supplying the id for the network you wish to remove
There will be no response from the server when you send the command so will need to list the networks to confirm removal.
