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


Settings


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 EC2 configuration

source $TOP_DIR/eucarc

Import exercise configuration

source $TOP_DIR/exerciserc

Remove old certificates

rm -f $TOP_DIR/cacert.pem
rm -f $TOP_DIR/cert.pem
rm -f $TOP_DIR/pk.pem

If nova api is not enabled we exit with exitcode 55 so that the exercise is skipped

is_service_enabled n-api || exit 55

Get Certificates

nova x509-get-root-cert $TOP_DIR/cacert.pem
nova x509-create-cert $TOP_DIR/pk.pem $TOP_DIR/cert.pem

Max time to wait for image to be registered

REGISTER_TIMEOUT=${REGISTER_TIMEOUT:-15}

BUCKET=testbucket
IMAGE=bundle.img
truncate -s 5M /tmp/$IMAGE
euca-bundle-image -i /tmp/$IMAGE || die $LINENO "Failure bundling image $IMAGE"

euca-upload-bundle --debug -b $BUCKET -m /tmp/$IMAGE.manifest.xml || die $LINENO "Failure uploading bundle $IMAGE to $BUCKET"

AMI=`euca-register $BUCKET/$IMAGE.manifest.xml | cut -f2`
die_if_not_set $LINENO AMI "Failure registering $BUCKET/$IMAGE"

Wait for the image to become available

if ! timeout $REGISTER_TIMEOUT sh -c "while euca-describe-images | grep $AMI | grep -q available; do sleep 1; done"; then
    die $LINENO "Image $AMI not available within $REGISTER_TIMEOUT seconds"
fi

Clean up

euca-deregister $AMI || die $LINENO "Failure deregistering $AMI"
