Configuring OpenStack Services to use High Available OpenStack Image API

Your OpenStack services must now point their OpenStack Image API configuration to the highly available, virtual cluster IP address — rather than an OpenStack Image API server’s physical IP address as you normally would.

For OpenStack Compute, for example, if your OpenStack Image API service IP address is 192.168.42.104 as in the configuration explained here, you would use the following line in your nova.conf file:

glance_api_servers = 192.168.42.103

You need also to create the OpenStack Image API Endpoint with this IP.

	Note
	If you are using both private and public IP addresses, you should create two Virtual IP addresses and define your endpoint like this:

keystone endpoint-create --region $KEYSTONE_REGION --service-id $service-id --publicurl 'http://PUBLIC_VIP:9292' --adminurl 'http://192.168.42.103:9292' --internalurl 'http://192.168.42.103:9292'
