Openstack / Create Port With Fixed Ip
Create Port With Fixed Ip
Create a port on a network with a fixed IP address in OpenStack.
openstack port create --network <network_id> --fixed-ip subnet=<subnet_id>,ip-address=192.168.1.50 <port_name> openstack port create --network <network_id> --fixed-ip subnet=<subnet_id>,ip-address=192.168.1.50 <port_name> #!/bin/bash
# Create Port With Fixed Ip
openstack port create --network {{network_id}} --fixed-ip subnet={{subnet_id}},ip-address=192.168.1.50 {{port_name}} import subprocess
# Create Port With Fixed Ip
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"openstack",
"port",
"create",
"--network",
"<network_id>",
"--fixed-ip",
"subnet=<subnet_id>,ip-address=192.168.1.50",
"<port_name>"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:

run_command() When To Use
During deployment of predetermined network settings where specific IP allocations are necessary.
Pro Tip
Verify subnet availability and IP address validity to avoid allocation conflicts.
Anatomy of Output
Understanding the result
+--------------------------------------+------+----------+-------------------+-----------+ Output Header Shows port details including fixed IP.
| ID | Name | Network ID | Fixed IP Address | Status | Column Details Details of the created port including designated IP.
| 34567890-abcd-ef00-3333-445566778899 | fixed-ip-port | 87654321-dcba-9876-5432-abcdef012345 | 192.168.1.50 | ACTIVE | Port Entry Indicates a successfully created port with a fixed IP.
Troubleshooting
Common pitfalls
Subnet not found (HTTP 404)
Solution: Ensure that the specified subnet ID is correct.
IP address allocation conflict (HTTP 409)
Solution: Choose an unused IP from the specified subnet.
Invalid fixed IP (HTTP 400)
Solution: Ensure the IP address is valid and within the subnet range.
