Nova Commands |
usage: nova [optional arguments...] [subcommand]
[optional arguments] are shown at the bottom of this web page
- nova list List instances, check status of instance
- nova image-list List images
- nova flavor-list List flavors
- nova boot --image IMAGE --flavor FLAVOR INSTANCE_NAME Boot an instance using flavor and image names (if names are unique)
- nova boot --image cirros-0.3.1-x86_64-uec --flavor m1.tiny MyUniqueInstanceName Boot an instance using an unique image name.
- nova show NAME Get the details
- nova show INSTANCE-ID Same as above but with ID instead of name
- nova console-log INSTANCE-ID View the log
- nova meta volumeTwoImage set newmeta='my meta data'
- nova image-create volumeTwoImage snapshotOfVolumeImage
- nova image-show snapshotOfVolumeImage
- nova pause NAME
- nova unpause NAME
- nova suspend NAME
- nova resume NAME
- nova stop NAME
- nova start NAME
- nova delete INSTANCE-ID
- nova reboot NAME
- nova boot --user-data Injects file into booting instance's /var/lib/cloud directory
- nova secgroup-list
- nova secgroup-add-group-rule default default icmp -1 -1 Add ping support (ICMP type and code, negative means unlimited)
- nova secgroup-add-group-rule default default tcp 22 22 Add SSH to security group
for inst in $(nova list --all-tenants --host r000001m001 --fields id,instance_name | grep "instance-" | cut -d ' ' -f 2); do nova start $inst; done
- This for loop loads variable $inst with instance ID
- nova list: will list all vms which could be a really big list unless it is pared down.
- The --all-tenants includes all tenants, not just the admin tenant
- The host r00001m001 is the compute node's ID that we want to evacuate, which you would have had to determine previously with a nova host-list
- The fields id works with nova list and extracts values of specified fields. You can find valid field names in the Property column with: nova show INSTANCE_ID
- Then pipe this output to grep and filter on the string instance-
- Then pipe this output to cut which will use a delimiter = and grab the second field
- Now the variable $inst = the instance's ID
- Start that instance with nova start $inst
- End the for loop (bash for: do it again)
