Step 1 – Retrieve the address and secret for the target AWS PCS cluster - AWS PCS

Step 1 – Retrieve the address and secret for the target AWS PCS cluster

Retrieve details about the target AWS PCS cluster using the AWS CLI with the command that follows. Before running the command, make the following replacements:

  • Replace region-code with the AWS Region where the target cluster is running.

  • Replace cluster-ident with the name or identifier for the target cluster

aws pcs get-cluster --region region-code --cluster-identifier cluster-ident

The command will return output similar to this example.

        },

            "subnetIds": [

            "securityGroupIds": [
                "sg-0123456789abcdef0"

        },
        "endpoints": [
            {
                "type": "SLURMCTLD",

                "port": "6817"
            }
        ]
    }
}

In this sample, the cluster Slurm controller endpoint has an IP address of 10.3.149.220 and it is running on port 6817. The secretArn will be used in later steps to retrieve the cluster secret. The IP address and port will be used in later steps to configure the sackd service.
