Script or Playbook to ADD Openstack neutron port add multiple IPs to an instance

Question

Adding multiple ips to an openstack VMs either existing or new VM its horrible like am getting request to add more than 200 ips to an instance. How do i write a script or playbook ?

starting IP from 192.168.0.50 to 192.168.0.150

How i add multiple ips by manually here its

$ source Project_admin

$ openstack network list | grep Test12

| ID                             | Name  | Subnet           | ID |

| kshd332sjkh-kjhj-sdsds-sdsdsds |Test12 | (192.168.0.0/24) | derere43e-erere-drerer-erererer |

$ openstack port list | grep 192.168.0.49 # (it show the First NIC port information and Port ID of an Single VM its a primary NIC)

Here my first NIC port id is 3k3j43434-skdjk-erere-2323

#openstck port set --fixed-ip subnet=**derere43e-erere-drerer-erererer**,ip-address=192.168.0.50 --fixed-ip subnet-derere43e-erere-drerer-erererer,ip-address=192.168.0.51 --fixed-ip subnet-derere43e-erere-drerer-erererer,ip-address=192.168.0.52 --fixed-ip subnet-derere43e-erere-drerer-erererer,ip-address=192.168.0.53    **3k3j43434-skdjk-erere-2323** **(myfirst-nic-port-id of 192.168.0.49)**

How do i perform this using script/python or playbook using os_port .is any way to achieve these would be more helpful my rotional task

Answer 1

What OS are you on? If you have a shell like Bash at your disposal this would work for your specific example:

for octet in {50..150};do
openstack port set --fixed-ip subnet-derere43e-erere-drerer-erererer,ip-address=192.168.0.$octet
done
