Openstack / Create Flavor With Ephemeral Swap
Create Flavor With Ephemeral Swap
Creates a new OpenStack flavor with ephemeral storage and swap space.
openstack flavor create <flavor_name> --vcpus 4 --ram 8192 --disk 40 --ephemeral 10 --swap 512 openstack flavor create <flavor_name> --vcpus 4 --ram 8192 --disk 40 --ephemeral 10 --swap 512 #!/bin/bash
# Create Flavor With Ephemeral Swap
openstack flavor create {{flavor_name}} --vcpus 4 --ram 8192 --disk 40 --ephemeral 10 --swap 512 import subprocess
# Create Flavor With Ephemeral Swap
# Make sure to replace <placeholders> with actual values

run_command() When To Use
When deploying environments that require temporary storage for instances.
Pro Tip
Be aware of the total ephemeral storage limits set at the project level.
Command Builder
Tune the command before you copy it
openstack flavor create <flavor_name> --vcpus 4 --ram 8192 --disk 40 --ephemeral 10 --swap 512 Anatomy of Output
Understanding the result
Flavor created: {flavor_name} Creation Confirmation Indicates successful creation of the flavor with specified properties.
Details: vCPUs 4, RAM 8192, Disk 40, Ephemeral 10, Swap 512 Flavor Specifications Displays the resource allocations for the newly created flavor.
+--------------------------+ End of Output Indicates completion of flavor creation command.
Troubleshooting
Common pitfalls
Error: Invalid swap size specified
Solution: Ensure swap size is a non-negative integer.
Quota exceeded for ephemeral storage
Solution: Check usage against your project's ephemeral storage limits.
Flavors may not exceed 8 vCPUs or 64GB RAM
Solution: Adjust configuration to fit within allowed limits.
