#Set up a Private OpenStack Cloud using Simplestreams
#Overview
#When Juju bootstraps a cloud, it needs two critical pieces of information:
#The UUID of the image to use when starting new compute instances.
#The URL from which to download the correct version of a tools tarball.
#This necessary information is stored in a json metadata format called "Simplestreams". For supported public cloud services such as Amazon Web Services, HP Cloud, Azure, etc, no action is required by the end user. However, those setting up a private cloud, or who want to change how things work (eg use a different Ubuntu image), can create their own metadata.
#This page explains how to use Juju and additional tools to generate this Simplestreams metadata and configure OpenStack to use them.
#Requirements
#python-openstackclient
#python-swiftclient
#Generating the metadata
sudo apt-get install python-openstackclient python-swiftclient
#To begin, create a directory to hold the generated metadata:
mkdir -p ~/simplestreams/images
#Now, if necessary, source the nova.rc file for your cloud:
. ~/joid_config/admin-openrcpublic
#We can now determine the region name for the cloud by running:
#OS_REGION_NAME=`openstack endpoint list -c Region -f value | head -1`
#The output from the above command will be similar to the following:
#Next, enter the following command to determine the Image ID of the cloud image in glance:
X_IMAGE_ID=`openstack image list -f value | grep -i xenial | cut -f 1 -d " "`
T_IMAGE_ID=`openstack image list -f value | grep -i trusty | cut -f 1 -d " "`
#The following example output shows two images listed, Ubuntu 16.04 (Xenial) and Ubuntu 14.04 (Trusty).
#Take a note of the image IDs for the images you want added to Simplestreams. These will be used in the next step.
#We can now use Juju to generate the metadata:
juju metadata generate-image -d ~/simplestreams -i $X_IMAGE_ID -s xenial -r $OS_REGION_NAME -u $OS_AUTH_URL
juju metadata generate-image -d ~/simplestreams -i $T_IMAGE_ID -s trusty -r $OS_REGION_NAME -u $OS_AUTH_URL
#To verify that the correct metadata files have been generated, you may run:
#You should see .json files containing the details we just added on the images.
ls ~/simplestreams/*/streams/*
#Upload the Simplestreams Metadata to Swift
openstack container create simplestreams
openstack container list
openstack container show simplestreams
cd ~/simplestreams
swift upload simplestreams *
cd -
swift stat simplestreams
swift post simplestreams --read-acl .r:*
openstack service list product-streams > /dev/null 2>&1 || openstack service create --name product-stream --description "Product Simple Stream" product-streams
SWIFT_URL=`openstack endpoint list --service swift --interface internal -c URL -f value`
openstack endpoint create --region $OS_REGION_NAME product-streams public $SWIFT_URL/simplestreams/images
openstack endpoint create --region $OS_REGION_NAME product-streams internal $SWIFT_URL/simplestreams/images
