# Virtlet currently ignores image tags, but their meaning may change
# in future, so it’s better not to set them for VM pods. If there’s no tag
# provided in the image specification kubelet defaults to
# imagePullPolicy: Always, which means that the image is always
# redownloaded when the pod is created. In order to make pod creation
# faster and more reliable, we set imagePullPolicy to IfNotPresent here
# so a previously downloaded image is reused if there is one
# in Virtlet’s image store
