Openstack Image Service

The Image service (glance) enables users to discover, register, and retrieve virtual machine

Source the project credentials to gain access to project-only CLI commands:

. project-openrc

Download the Cirros for Testing Image

wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img

Upload the image to the Image service using the QCOW2 disk format, bare container format, and public visibility so all projects can access it:

openstack image create "cirros"  --file cirros-0.4.0-x86_64-disk.img --disk-format qcow2 --container-format bare --public

Upload the image to the Image service using the vmdk disk format, ova container format, and public visibility so all projects can access it

openstack image create  centos-7-repo-mirror --container-format ova  --disk-format vmdk --file centos7-mirror-disk1.vmdk --public

Upload the image to the Image service using the ISO disk format, bare container format, and public visibility so all projects can access it

openstack image create  rhel-workstation-7.3 --public  --container-format bare --disk-format iso --file rhel-workstation-7.3-x86_64-dvd.iso  --public
