Compute (nova)

List instances, check status of instance $ nova list

List images $ nova image-list

Boot an instance using flavor and image names (if names are unique) $ nova boot –image IMAGE –flavor FLAVOR INSTANCE_NAME $ nova boot –image cirros-0.3.1-x86_64-uec –flavor m1.tiny

Login to instance

ip netns

ip netns exec NETNS_NAME ssh [email protected]

ip netns exec qdhcp-6021a3b4-8587-4f9c-8064-0103885dfba2 \

ssh [email protected]

Note In CirrOS the password for user cirros is “cubswin:)” without the quotes.

Show details of instance $ nova show NAME $ nova show MyFirstInstance

View console log of instance $ nova console-log MyFirstInstance

Set metadata on an instance $ nova meta volumeTwoImage set newmeta=’my meta data’

Inject user data and files into an instance $ nova boot –user-data FILE INSTANCE $ nova boot –user-data userdata.txt –image cirros-qcow2
–flavor m1.tiny MyUserdataInstance2

To validate that the file was injected, use ssh to connect to the instance, and look in /var/lib/cloud for the file.

Inject a keypair into an instance and access the instance with that keypair Create keypair $ nova keypair-add test > test.pem $ chmod 600 test.pem Start an instance (boot) $ nova boot –image cirros-0.3.0-x86_64 –flavor m1.small
–key_name test MyFirstServer

Use ssh to connect to the instance

ip netns exec qdhcp-98f09f1e-64c4-4301-a897-5067ee6d544f \

ssh -i test.pem [email protected]

Manage security groups Add rules to default security group allowing ping and SSH between instances in the default security group $ nova secgroup-add-group-rule default default icmp -1 -1 $ nova secgroup-add-group-rule default default tcp 22 22

Networking (neutron)

Create network $ neutron net-create NAME

Create a subnet $ neutron subnet-create NETWORK_NAME CIDR $ neutron subnet-create my-network

Block Storage (cinder) Used to manage volumes and volume snapshots that attach to instances.

Create a new volume $ cinder create SIZE_IN_GB –display-name NAME $ cinder create 1 –display-name MyFirstVolume

Boot an instance and attach to volume $ nova boot –image cirros-qcow2 –flavor m1.tiny MyVolumeInstance

List volumes, notice status of volume $ cinder list

Attach volume to instance after instance is active, and volume is available $ nova volume-attach INSTANCE_ID VOLUME_ID auto $ nova volume-attach MyVolumeInstance /dev/vdb auto

Manage volumes after login into the instance List storage devices

fdisk -l

Make filesystem on volume

mkfs.ext3 /dev/vdb

Create a mountpoint

mkdir /myspace

Mount the volume at the mountpoint

mount /dev/vdb /myspace

Create a file on the volume

touch /myspace/helloworld.txt

ls /myspace

Unmount the volume

umount /myspace

Object Storage (swift) Display information for the account, container, or object $ swift stat $ swift stat ACCOUNT $ swift stat CONTAINER $ swift stat OBJECT
