I keep forgetting syntax for these commands, maybe simply because I’m not using them too often. We mainly use Horizon web interface, do we? Anyway, here we go:
Keystone
keystone user-list keystone token-get
Glance
glance image-list glance image-create --min-disk 20 --name="CentOS 7 2015-12-17" \ --disk-format=qcow2 --container-format=bare --property architecture=x86_64 \ --progress --is-public yes --is-protected true \ --file CentOS-7-x86_64-GenericCloud.qcow2
Nova
nova list
nova image-list
nova host-list
nova service-list
nova-manage service describe_resource prod018.openstack.mielnet.pl
nova hypervisor-show prod017.openstack.mielnet.pl
#on the controller
multitail /var/log/nova/{scheduler.log,console.log,conductor.log}
# on the compute node
multitail /var/log/nova/compute.log
Neutron
neutron ext-list neutron security-group-list neutron security-group-show 626de015-b43f-405f-add2-e9797bcdb1d6 neutron router-list neutron subnet-list neutron net-external-list neutron quota-list neutron net-list
Cinder
cinder absolute-limits cinder backup-list cinder list cinder service-list cinder type-list cinder-manage service list cinder service-disable prod016.openstack.mielnet.pl cinder-volume cinder service-disable prod016.openstack.mielnet.pl@gluster cinder-volume cinder service-list # I messed up and had to resolve problem in a brutal way, don't try this at home: mysql -e "update services set deleted = 1 where host like 'prod016.openstack.mielnet.pl%' and disabled = 1 " cinder
Swift
