In this article we are going to explain about Openstack images management. Generally this cam be done via Horizon dashboard under Images section. But we will explain how to upload images via commandline.

Download an image from internet. We use debian image for example. Login to the server where the glance service is running, in our case it’s a allinone node.

cd /root

wget http://cdimage.debian.org/cdimage/openstack/current-9/debian-9-openstack-amd64.qcow2

Source your keystone admin credentials using below source command

[root@os ~]# source keystonerc_admin
[root@os ~(keystone_admin)]#

Go to the folder where your have place cloud image qcow2 file.

[root@os ~(keystone_admin)]# cd /root/
[root@os ~(keystone_admin)]#

To upload an image to glance

Syntax :

 [root@os ~(keystone_admin)]# openstack image create –disk-format qcow2 –container-format bare   –public –file  {Name-Cloud-Image}.qcow2     <Name-of-Image>

Example : Let’s assume I want to upload Debian9 qcow2 file.

[root@os ~(keystone_admin)]# openstack image create --disk-format qcow2 --container-format bare --public --file debian-9-openstack-amd64.qcow2  debian1

To view the uploaded images

[root@os ~(keystone_admin)]# openstack image list
