OpenStack tools

Small helper scripts for OpenStack administration.

Requirements

• Python 3.10+
• OpenStack credentials in the usual OS_* environment variables
• openstacksdk for openstack-domain-quota-usage.py
• OpenStack CLI for openstack-image-share.py and openstack-project-cleanup.py

pip install -r requirements.txt

openstack-domain-quota-usage.py

Summarizes quota usage across projects in a domain: cores, RAM in GiB, and volume storage in TiB.

source openrc.sh
python3 openstack-domain-quota-usage.py

Useful options:

python3 openstack-domain-quota-usage.py --workers 4
python3 openstack-domain-quota-usage.py --limit-cores 400 --limit-ram 800 --limit-storage 20

Domain/project selection uses OS_DOMAIN_ID, OS_DOMAIN_NAME, OS_PROJECT_DOMAIN_NAME, or OS_USER_DOMAIN_NAME.

openstack-image-share.py

Accepts a shared Glance image across visible projects. With --add-image, also runs openstack image add project before accepting, which requires authenticating as the image owner.

source openrc.sh
python3 openstack-image-share.py IMAGE_ID
python3 openstack-image-share.py --add-image IMAGE_ID

openstack-project-cleanup.py

Lists project resources and prompts before deleting each group:

• Deletes servers, volumes, floating IPs, routers, ports, networks, then the ssh_key keypair.
• Detaches router interfaces before deleting routers.
• Skips networks named public; only internal, vxlan, non-shared networks are eligible.

source openrc.sh
python3 openstack-project-cleanup.py PROJECT_NAME

Run any script with --help for all options.
