Here is quick reference of the most used command-line commands:<\/p>\n

You will probably want to know what is the name of your openstack deployment? Aka Queens, Pines, Ocata, Newton but also to Mitaka, Liberty, Kilo & Juno.
\nWhich OpenStack version is installed? <\/p>\n
$ openstack –version
\nOnce you have the version, check here for the name.
\nSame way for other specific services too, for example:<\/p>\n
$ nova-manage –version
\n$ cinder-manage –version
\n$ glance-manage –version
\nIdentity Service (aka Keystone):<\/p>\n

$ openstack service list
\nCompute (aka Nova)<\/p>\n
List instances, notice status of instance<\/p>\n
$ openstack server list
\nList images<\/p>\n
$ openstack image list
\nList flavors<\/p>\n

\n NewInstance
\nLogin to a Linux instance<\/p>\n
# ip netns<\/p>\n
# ip netns exec NETNS_NAME ssh USER@SERVER<\/p>\n

$ openstack server show NAME
\n$ openstack server show NewInstance
\nView console log of instance<\/p>\n
$ openstack console-log NewInstance
\nSet metadata on an instance<\/p>\n
$ nova meta volumeTwoImage set newmeta=’my new meta data’
\nCreate an instance snapshot<\/p>\n
$ openstack image-create volumeImage snapshot1OfVolumeImage
\n$ openstack image-show snapshot1OfVolumeImage<\/p>\n
Stop, Pause, resize, rebuild and offcourse reboot an instance<\/p>\n
Pause<\/p>\n
$ openstack server pause NAME

\nStop<\/p>\n
$ openstack server stop NAME
\nStart<\/p>\n
$ openstack server start NAME
\nResize<\/p>\n
$ openstack server resize NAME FLAVOR
\n$ openstack server resize myinstance m2.large
\n$ openstack server resize –confirm myinstance
\nRebuild<\/p>\n
$ openstack server rebuild NAME IMAGE
\n$ openstack server rebuild myinstance cirros-121
\nReboot<\/p>\n
$ openstack server reboot NAME
\n$ openstack server reboot myinstance
\nImage Service (aka Glance)<\/p>\n
List images you can access<\/p>\n
$ openstack image list
\nDelete specified image<\/p>\n
$ openstack image delete IMAGE
\nDescribe a specific image<\/p>\n
$ openstack image show IMAGE
\nUpdate image<\/p>\n
$ openstack set imageIMAGE
\nNetworking Service (aka Neutron)<\/p>\n
Create network<\/p>\n
$ openstack network create NAME
\nCreate a subnet<\/p>\n
$ openstack subnet create –subnet-pool SUBNET –network NETWORK SUBNET_NAME
\n$ openstack subnet create –subnet-pool 10.0.0.2\/30 –network network1 subnetwork1
\nList network and subnet<\/p>\n
$ neutron net-list
\n$ neutron subnet-list
\nExamine details of network and subnet<\/p>\n
$ neutron net-show ID_OR_NAME_OF_NETWORK
\n$ neutron subnet-show ID_OR_NAME_OF_NETWORK
\nBlock Storage Service (aka Cinder)<\/p>\n
Create a new volume<\/p>\n
$ openstack volume create –size SIZE_IN_GB NAME
\n$ openstack volume create –size 10 MyVolume
\nBoot an instance and attach to volume<\/p>\n
$ openstack server create –image cirros-qcow2 –flavor m2.large MyVolume
\nList volumes<\/p>\n
$ openstack volume list
\nAttach volume to instance after instance is active, and volume is available<\/p>\n
$ openstack server add volume INSTANCE_ID VOLUME_ID
\nManage volumes after login into the instance<\/p>\n
List storage devices<\/p>\n
# fdisk -l
\nMake filesystem on volume<\/p>\n
# mkfs.ext3 \/dev\/vdb
\nCreate a mountpoint<\/p>\n
# mkdir \/myspace
\nMount the volume at the mountpoint<\/p>\n
# mount \/dev\/vdb \/myspace
\nCreate a file on the volume<\/p>\n
