"""
Ray operator for Kubernetes.
Reads ray cluster config from a k8s ConfigMap, starts a ray head node pod using
create_or_update_cluster(), then runs an autoscaling loop in the operator pod
executing this script. Writes autoscaling logs to the directory
/root/ray-operator-logs.
In this setup, the ray head node does not run an autoscaler. It is important
NOT to supply an --autoscaling-config argument to head node's ray start command
in the cluster config when using this operator.
To run, first create a ConfigMap named ray-operator-configmap from a ray
cluster config. Then apply the manifest at python/ray/autoscaler/kubernetes/operator_configs/operator_config.yaml
For example:
kubectl create namespace raytest
kubectl -n raytest create configmap ray-operator-configmap --from-file=python/ray/autoscaler/kubernetes/operator_configs/test_cluster_config.yaml
kubectl -n raytest apply -f python/ray/autoscaler/kubernetes/operator_configs/operator_config.yaml
