openslo-kubernetes-apiserver.yml

# This example shows the same example as kubernetes-apiserver.yml but using OpenSLO spec.
# It will generate the Prometheus rules in a Prometheus rules format.
#
# Take into account that OpenSLO spec has the concept of single SLO with multiple objectives
#
# `sloth generate -i ./examples/openslo-kubernetes-apiserver.yml`
