Slurmqueue naming validation errors

Issue: Error when using hyphens in SlurmQueue names

AWS ParallelCluster Version

• Tested on versions: 3.10 & 3.11

Description

When configuring a cluster with hyphens in the SlurmQueue names, the following error occurs:

Example Configuration snippet:

SlurmQueues:
  - Name: a10-medium
    JobExclusiveAllocation: true
    ComputeResources:
      - Name: a10-medium
        InstanceType: g5.12xlarge
        MinCount: 0
        MaxCount: 4
        Efa:
          Enabled: true

Error Message

{
  "configurationValidationErrors": [
    {
      "level": "ERROR",
      "type": "NameValidator",
      "message": "Invalid name 'a10-medium'. Name must begin with a letter and only contain lowercase letters, digits and hyphens."
    }
  ]
}

Expected Behavior

The configuration should allow hyphens in SlurmQueue names without producing a validation error.

Steps to Reproduce

1. Define a cluster configuration with a SlurmQueue name that includes hyphens (e.g., a10-medium).
2. Attempt to create the cluster.

Request

Is there any plan to adjust the validation rules to allow hyphens in SlurmQueue names, or should I follow a different naming convention?

Thanks!

Hello, slurm queue names do allow hypens (ex: queue-0), however they must start with a letter. The example you gave starts with a number and therefore throws a validation error.
