kubevirt-inventory

An ansible dynamic inventory script for kubevirt.

usage

This inventory relies on environment variables to work properly. Before calling the script, export the kubevirt endpoint and token. Optionally, a project/namespace can be specified. If no namespace is set, the script will return a list of all virtual machine instances in the cluster.

# export OPENSHIFT_TOKEN=$(oc whoami -t)
# export OPENSHIFT_ENDPOINT=$(oc config view | awk '/server/ {print $2}')
# ./kubevirt-inventory.py
