Aws / Describe Eks Nodegroup

Describe Eks Nodegroup

Describe a specific node group within an EKS cluster.

Terminal

aws eks describe-nodegroup --cluster-name <cluster_name> --nodegroup-name <nodegroup_name>

aws eks describe-nodegroup --cluster-name <cluster_name> --nodegroup-name <nodegroup_name>

#!/bin/bash

# Describe Eks Nodegroup
aws eks describe-nodegroup --cluster-name {{cluster_name}} --nodegroup-name {{nodegroup_name}}

import subprocess

# Describe Eks Nodegroup
# Make sure to replace <placeholders> with actual values
def run_command():
    cmd = [
        "aws",
        "eks",
        "describe-nodegroup",
        "--cluster-name",
        "<cluster_name>",
        "--nodegroup-name",
        "<nodegroup_name>"
    ]
    
    try:
        print(f"Executing: {' '.join(cmd)}")
        subprocess.run(cmd, check=True)
    except subprocess.CalledProcessError as e:
        print(f"Error: {e}")
    except FileNotFoundError:
        print("Error: aws not found. Please install it first.")

    run_command()

When To Use

When debugging issues related to node configurations or deployments within a cluster.

Pro Tip

Use `--include-extended` to fetch detailed configuration data beyond the standard output.

{\n  "nodegroup": {\n    "nodegroupName": "example-nodegroup",\n    "clusterName": "example-cluster",\n    "status": "ACTIVE",\n    "scalingConfig": {\n      "minSize": 2,\n      "maxSize": 5,\n      "desiredSize": 3\n    },\n    "resources": {\n      "autoScalingGroups": [\n        {\n          "name": "example-asg"\n        }\n      ]\n    }\n  }\n}

Anatomy of Output

Understanding the result

NodeGroupName: my-node-group Node Group Name

The name of the described node group.

Status: ACTIVE Node Group Status

Indicates operational state of the node group.

ScalingConfig: 2 desired, 1 running, 0 pending Scaling Information

Shows current scaling states of the node group.

Power User Variants

Optimized versions

aws eks describe-nodegroup --cluster-name my-cluster --nodegroup-name my-node-group --include-extended

Request extended details about the node group.

aws eks describe-nodegroup --cluster-name my-cluster --nodegroup-name my-node-group --output json

Output details in JSON format for automation scripts.

Troubleshooting

Common pitfalls

An error occurred (ClusterNotFound) when calling the DescribeNodegroup operation: Cluster 'my-cluster' not found

Solution: Confirm cluster is created and accessible in the region.

An error occurred (NodegroupNotFound) when calling the DescribeNodegroup operation: Nodegroup 'my-node-group' not found

Solution: Check that the node group name is correct and exists in the specified cluster.

An error occurred (UnauthorizedOperation) when calling the DescribeNodegroup operation: You are not authorized to perform this operation

Solution: Review IAM permissions for the user attempting to retrieve the node group description.

Command Breakdown

What each part is doing

aws: Base Command; The executable that performs this operation. Here it runs Aws before the shell applies any redirect operators.
<cluster_name>: cluster name; The value supplied for cluster name.
<nodegroup_name>: nodegroup name; The value supplied for nodegroup name.
--cluster-name: Command Option; Tool-specific option used by this command invocation.
--nodegroup-name: Command Option; Tool-specific option used by this command invocation.

How To Run

Execution path

Step 1
Run the command: aws eks describe-nodegroup --cluster-name my-cluster --nodegroup-name my-nodegroup
Step 2
Verify the output for the expected nodegroup details, especially status and scalingConfig.
