Adding tags to the aws ec2 instances

Ray Clusters

Hi,

I’m relatively new to running aws ec2 instances. Our IT dept requires us to provide tags during ec2 instance creation. I’ve tried running ray up using a basic YAML (supplied below), however I get the follow error. Any help would be appreciated. Thanks.

YAML (basic template provided by Ray)

# An unique identifier for the head node and workers of this cluster.
cluster_name: minimal

# Cloud-provider specific configuration.

    type: aws

I have a similar issue and I think you are very close! Try removing the - before ‘Tags’ in your YAML file like this:

TagSpecifications:
- ‘ResourceType’: ‘instance’
‘Tags’: {‘Key’: ‘CostCode’, ‘Value’: ‘1234’}

Update: it worked for me.
