In high availability glance, a service acts as a backend storage for the object storage called Swift. Image service is used to store the images in a shared manner.
As the initial step of activating image services, we have to install the Python glance client using this:
sudo apt-get install glance python-glanceclient
Now, we need to modify several image service files for this implementation. The first file that we must modify is glance-api.conf
that is available under /etc/glance/
. The modification is done using following command:
sudo gedit /etc/glance/glance-api.conf
We changed our Virtual IP for Swift, database, and authentication:
Then, we need to modify the next file called glance-registry.conf
available under /etc/glance
. This is done as follows:
sudo gedit /etc/glance/glance-registry.conf
The following changes are to be done in the preceding glance-registry.conf file:
The next file to be edited is the glance-cache...
