Hello all,
I am completely new to this, and I got stuck at starting up the ray cluster.
Here is my .yaml configuration:
# An unique identifier for the head node and workers of this cluster.
cluster_name: default
# The maximum number of workers nodes to launch in addition to the head
# node.
max_workers: 2
# The autoscaler will scale up the cluster faster with higher upscaling speed.
# E.g., if the task requires adding more nodes then autoscaler will gradually
# scale up the cluster in chunks of upscaling_speed*currently_running_nodes.
# This number should be > 0.
upscaling_speed: 1.0
# This executes all commands on all nodes in the docker container,
# and opens all the necessary ports to support the Ray cluster.
# Empty string means disabled.
docker: {}
# If a node is idle for this many minutes, it will be removed.
idle_timeout_minutes: 5
# Cloud-provider specific configuration.
provider:
type: aws
region: us-east-1
# Availability zone(s), comma-separated, that nodes may be launched in.
# Nodes will be launched in the first listed availability zone and will
# be tried in the subsequent availability zones if launching fails.
availability_zone: us-east-1f
# Whether to allow node reuse. If set to False, nodes will be terminated
# instead of stopped.
cache_stopped_nodes: True # If not present, the default is True.
# security_group:
# GroupName: default
# How Ray will authenticate with newly launched nodes.
auth:
ssh_user: ubuntu #ec2-user
# By default Ray creates a new private keypair, but you can also use your own.
# If you do so, make sure to also set "KeyName" in the head and worker node
# configurations below.
# ssh_private_key: /path/to/your/key.pem
ssh_private_key: C:/Users/Stefan/.aws/yt_dl_ray_keypair.pem
# Tell the autoscaler the allowed node types and the resources they provide.
# The key is the name of the node type, which is just for debugging purposes.
# The node config specifies the launch config and physical instance type.
available_node_types:
ray.head.default:
# The node type's CPU and GPU resources are auto-detected based on AWS instance type.
# If desired, you can override the autodetected CPU and GPU resources advertised to the autoscaler.
# You can also set custom resources.
# For example, to mark a node type as having 1 CPU, 1 GPU, and 5 units of a resource called "custom", set
# resources: {"CPU": 1, "GPU": 1, "custom": 5}
resources: {}
# Provider-specific config for this node type, e.g. instance type. By default
# Ray will auto-configure unspecified fields such as SubnetId and KeyName.

head_node_type: ray.head.default

# "/path2/on/remote/machine": "/path2/on/local/machine",
}
# Files or directories to copy from the head node to the worker nodes. The format is a
# list of paths. The same path on the head node will be copied to the worker node.
# This behavior is a subset of the file_mounts behavior. In the vast majority of cases

It successfully starts an EC2 instance on AWS and passes initialization, but in the terminal I get the following error:
<1/1> Setting up head node
Prepared bootstrap config
New status: waiting-for-ssh

Running `uptime` as a test.

getsockname failed: Not a socket
Timeout, server 3.236.16.235 not responding.

Is someone seeing what I am doing wrong?
Thank you!
