I am running ray cluster using cluster.yaml file. I have 3 worker node and one head node. How can I set environment variable per node?

Do you want to set different env var per node?

Yes.
Actually, I want to set different values of variables for each node.

Yea, it’s doable.

Basically you need to specify a node type for each worker node. Under the config for each node type, you can specify worker_setup_commands (Cluster YAML Configuration Options — Ray 2.0.0) like ENV_VAR1=0 ray start --address=$RAY_HEAD_IP:6379 --object-manager-port=8076 --object-store-memory=80000000000. Or if you are using docker, you can use the run_options field and set “-e” arguments that will be passed to docker run.
