This script exits on an error so that errors don't compound and you see only the first error that occurred.

set -o errexit

Print the commands being run so that we can see the command that triggers an error. It is also useful for following allowing as the install occurs.

set -o xtrace


Keep track of the current directory

EXERCISE_DIR=$(cd $(dirname "$0") && pwd)
TOP_DIR=$(cd $EXERCISE_DIR/..; pwd)

Import common functions

source $TOP_DIR/functions

Import configuration

Import exercise configuration

If cinder is not enabled we exit with exitcode 55 which mean exercise is skipped.

is_service_enabled cinder || exit 55

Ironic does not currently support volume attachment.

[ "$VIRT_DRIVER" == "ironic" ] && exit 55

Instance type to create


Boot this image, use first AMI image if unset


Security group name


Instance and volume names

VOL_NAME="ex-vol-$(openssl rand -hex 4)"

Launching a server

List servers for tenant:

nova list


List the images available

glance image-list

Grab the id of the image to launch

IMAGE=$(glance image-list | egrep " $DEFAULT_IMAGE_NAME " | get_field 1)
die_if_not_set $LINENO IMAGE "Failure getting image $DEFAULT_IMAGE_NAME"

Security Groups

List security groups

nova secgroup-list

if is_service_enabled n-cell; then

Cells does not support security groups, so force the use of "default"

    echo "Using the default security group because of Cells."

Create a secgroup

    if ! nova secgroup-list | grep -q $SECGROUP; then
        nova secgroup-create $SECGROUP "$SECGROUP description"
        if ! timeout $ASSOCIATE_TIMEOUT sh -c "while ! nova secgroup-list | grep -q $SECGROUP; do sleep 1; done"; then
            echo "Security group not created"
            exit 1

Configure Security Group Rules

if ! nova secgroup-list-rules $SECGROUP | grep -q icmp; then
    nova secgroup-add-rule $SECGROUP icmp -1 -1
if ! nova secgroup-list-rules $SECGROUP | grep -q " tcp .* 22 "; then
    nova secgroup-add-rule $SECGROUP tcp 22 22

List secgroup rules

nova secgroup-list-rules $SECGROUP

Set up instance

List flavors

nova flavor-list

Select a flavor

INSTANCE_TYPE=$(nova flavor-list | grep $DEFAULT_INSTANCE_TYPE | get_field 1)
if [[ -z "$INSTANCE_TYPE" ]]; then

grab the first flavor in the list to launch if default doesn't exist

    INSTANCE_TYPE=$(nova flavor-list | head -n 4 | tail -n 1 | get_field 1)
    die_if_not_set $LINENO INSTANCE_TYPE "Failure retrieving INSTANCE_TYPE"

Clean-up from previous runs

nova delete $VM_NAME || true
if ! timeout $ACTIVE_TIMEOUT sh -c "while nova show $VM_NAME; do sleep 1; done"; then
    die $LINENO "server didn't terminate!"

Boot instance

VM_UUID=$(nova boot --flavor $INSTANCE_TYPE --image $IMAGE --security-groups=$SECGROUP $VM_NAME | grep ' id ' | get_field 2)
die_if_not_set $LINENO VM_UUID "Failure launching $VM_NAME"

Check that the status is active within ACTIVE_TIMEOUT seconds

if ! timeout $ACTIVE_TIMEOUT sh -c "while ! nova show $VM_UUID | grep status | grep -q ACTIVE; do sleep 1; done"; then
    die $LINENO "server didn't become active!"

Get the instance IP

IP=$(get_instance_ip $VM_UUID $PRIVATE_NETWORK_NAME)

die_if_not_set $LINENO IP "Failure retrieving IP address"

Private IPs can be pinged in single node deployments



Verify it doesn't exist

if [[ -n $(cinder list | grep $VOL_NAME | head -1 | get_field 2) ]]; then
    die $LINENO "Volume $VOL_NAME already exists"

Create a new volume

start_time=$(date +%s)

    die $LINENO "Failure creating volume $VOL_NAME"

    die $LINENO "Volume $VOL_NAME not created"

Get volume ID

VOL_ID=$(cinder list | grep $VOL_NAME | head -1 | get_field 1)
die_if_not_set $LINENO VOL_ID "Failure retrieving volume ID for $VOL_NAME"

Attach to server

start_time=$(date +%s)

if ! timeout $ACTIVE_TIMEOUT sh -c "while ! cinder list | grep $VOL_NAME | grep in-use; do sleep 1; done"; then

Clean up

Detach volume

start_time=$(date +%s)
nova volume-detach $VM_UUID $VOL_ID || die $LINENO "Failure detaching volume $VOL_NAME from $VM_NAME"
if ! timeout $ACTIVE_TIMEOUT sh -c "while ! cinder list | grep $VOL_NAME | grep available; do sleep 1; done"; then
    die $LINENO "Volume $VOL_NAME not detached from $VM_NAME"
end_time=$(date +%s)

Delete volume

if ! timeout $ACTIVE_TIMEOUT sh -c "while cinder list | grep $VOL_NAME; do sleep 1; done"; then
    die $LINENO "Volume $VOL_NAME not deleted"
end_time=$(date +%s)

Delete instance

nova delete $VM_UUID || die $LINENO "Failure deleting instance $VM_NAME"
if ! timeout $TERMINATE_TIMEOUT sh -c "while nova list | grep -q $VM_UUID; do sleep 1; done"; then
    die $LINENO "Server $VM_NAME not deleted"

if [[ $SECGROUP = "default" ]] ; then

Delete secgroup

    nova secgroup-delete $SECGROUP || die $LINENO "Failure deleting security group $SECGROUP"
