28 #Set up a Private OpenStack Cloud using Simplestreams
32 #When Juju bootstraps a cloud, it needs two critical pieces of information:
34 #The UUID of the image to use when starting new compute instances.
35 #The URL from which to download the correct version of a tools tarball.
36 #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.
38 #This page explains how to use Juju and additional tools to generate this Simplestreams metadata and configure OpenStack to use them.
42 #python-openstackclient
44 #Generating the metadata
47 sudo apt-get install python-openstackclient python-swiftclient
49 #To begin, create a directory to hold the generated metadata:
51 mkdir -p ~/simplestreams/images
53 #Now, if necessary, source the nova.rc file for your cloud:
55 . ~/joid_config/admin-openrc
57 #We can now determine the region name for the cloud by running:
59 #OS_REGION_NAME=`openstack endpoint list -c Region -f value | head -1`
60 #The output from the above command will be similar to the following:
62 #Next, enter the following command to determine the Image ID of the cloud image in glance:
64 X_IMAGE_ID=`openstack image list -f value | grep -i xenial | cut -f 1 -d " "`
65 T_IMAGE_ID=`openstack image list -f value | grep -i trusty | cut -f 1 -d " "`
67 #The following example output shows two images listed, Ubuntu 16.04 (Xenial) and Ubuntu 14.04 (Trusty).
69 #Take a note of the image IDs for the images you want added to Simplestreams. These will be used in the next step.
71 #We can now use Juju to generate the metadata:
73 juju metadata generate-image -d ~/simplestreams -i $X_IMAGE_ID -s xenial -r $OS_REGION_NAME -u $OS_AUTH_URL
74 juju metadata generate-image -d ~/simplestreams -i $T_IMAGE_ID -s trusty -r $OS_REGION_NAME -u $OS_AUTH_URL
76 #To verify that the correct metadata files have been generated, you may run:
77 #You should see .json files containing the details we just added on the images.
79 ls ~/simplestreams/*/streams/*
