openstack subnet delete {{subnet_id_or_name}} import subprocess
# Delete Subnet
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"openstack",
"subnet",
"delete",
"<subnet_id_or_name>"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:
print("Error: openstack not found. Please install it first.")

run_command() When To Use
When reconfiguring cloud infrastructure after testing or deployment phase.
Pro Tip
Run `openstack subnet show {{subnet_id}}` beforehand to verify dependencies and avoid breaking associated resources.
Warning
Destructive operation. Confirm the target path and keep a backup before executing.
