Installing OpenStack Image Servicevagrant ssh controller
sudo apt-get update
sudo apt-get -y install glance
sudo apt-get update
sudo apt-get -y install glance-client
Using an alternative release
sudo apt-get update
sudo apt-get -y install python-software-properties
sudo add-apt-repository ppa:openstack-ubuntu-testing/havana-trunk-testing
Configuring OpenStack Image Service with MySQL
vagrant ssh controller
1. create the glance database
MYSQL_ROOT_PASSWORD=openstack
mysql -uroot -p$MYSQL_ROOT_PASSWORD -e 'CREATE DATABASE glance;'
2. create a glance user
MYSQL_GLANCE_PASSWORD=openstack
mysql -uroot -p${MYSQL_ROOT_PASSWORD} -e "GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY '${MYSQL_GLANCE_PASSWORD}';"
mysql -uroot -p${MYSQL_ROOT_PASSWORD} -e "GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY '${MYSQL_GLANCE_PASSWORD}';"
3. configure the OpenStack Image Service to use the database
sudo sed -i "s,^sql_connection.*,sql_connection = mysql://glance:${MYSQL_DB_PASSWORD}@172.16.0.200/glance," /etc/glance/glance-{registry,api}.conf
change the sql_connections line to match the database credentials.
4. restart the glance-registry service
sudo stop glance-registry
sudo start glance-registry
5. restart the glance-api service
sudo stop glance-api
sudo start glance-api
6. glance database is versioned controlled under Ubuntu 12.04 to allow upgrade and downgrade of service.
glance-manage version_control 0
7. sync the database to ensure the correct table structure is present.
sudo glance-manage db_sync
Configuring OpenStack Image Service with OpenStack Identity Service
vagrant ssh controller
1. edit the /etc/glance/glance-api-paste.ini file and configure the section
paste.filter_factory = keystoneclient.middleware.auth_
token:filter_factory
admin_tenant_name = service
admin_user = glance
admin_password = glance
2. configure the /etc/glance/glance-api.conf file, to tell OpenStack Image Service to utilize OpenStack Identity Service
auth_host = 172.16.0.200
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = glance
admin_password = glance
config_file = /etc/glance/glance-api-paste.ini
flavor = keystone
3. edit the /etc/glance/glance-registry-paste.ini file and configure the section
paste.filter_factory = keystoneclient.middleware.auth_
token:filter_factory
admin_tenant_name = service
admin_user = glance
admin_password = glance
4. configure the /etc/glance/glance-registry.conf file, to tell OpenStack Image Service to utilize OpenStack Identity Service
auth_host = 172.16.0.200
auth_port = 35357
auth_protocol = http
admin_tenant_name = service
admin_user = glance
admin_password = glance
config_file = /etc/glance/glance-registry-paste.ini
flavor = keystone
5. restart the two OpenStack Image Service processes
sudo restart glance-api
sudo restart glance-registry
Managing images with OpenStack Image Service
sudo apt-get update
sudo apt-get -y install glance-client
export OS_TENANT_NAME=cookbook
export OS_USERNAME=admin
export OS_PASSWORD=openstack
export OS_AUTH_URL=http://172.16.0.1:5000/v2.0/
export OS_NO_CACHE=1
uploading Ubuntu images
1. download an Ubuntu cloud image
wget http://uec-images.ubuntu.com/precise/current/precise-server-cloudimg-amd64-disk1.img
2. upload the cloud image
glance image-create --name='Ubuntu 12.04 x86_64 Server' --disk-format=qcow2 --container-format=bare --public < precise-server-clouding-amd64-disk1.img
listing images
glance image-list
viewing image details
glance image-show IMAGE-ID
glance image-show 794dca52-5fcd-4216-ac8e-7655cdc88852
deleting images
glance image-delete IMAGE-ID
making private images public
When uploading an image, they get entered into OpenStack Image Service as private by default.
1. list and view the image
glance image-show IMAGE-ID
2. convert to a public image
glance image-update IMAGE-ID --is-public True
3. issue a public glance listing
glance image-show IMAGE-ID
Registering a remotely stored image
sudo apt-get update
sudo apt-get -y install glance-client
export OS_TENANT_NAME=cookbook
export OS_USERNAME=admin
export OS_PASSWORD=openstack
export OS_AUTH_URL=http://172.16.0.200:5000/v2.0/
export OS_NO_CACHE=1
