Kubectl / Check User Permission Specific Verb Resource

Check User Permission Specific Verb Resource

Use kubectl to verify if a user can perform a specific action on a Kubernetes resource.

Terminal

kubectl auth can-i <verb> <resource> -n <namespace>

kubectl auth can-i <verb> <resource> -n <namespace>

#!/bin/bash

# Check User Permission Specific Verb Resource
kubectl auth can-i {{verb}} {{resource}} {{[-n|--namespace]}} {{namespace}}

import subprocess

# Check User Permission Specific Verb Resource
# Make sure to replace <placeholders> with actual values
def run_command():
    cmd = [
        "kubectl",
        "auth",
        "can-i",
        "<verb>",
        "<resource>",
        "-n",
        "<namespace>"
    ]
    
    try:
        print(f"Executing: {' '.join(cmd)}")
        subprocess.run(cmd, check=True)
    except subprocess.CalledProcessError as e:
        print(f"Error: {e}")
    except FileNotFoundError:
        print("Error: kubectl not found. Please install it first.")

Solution: Check the user's role bindings and permissions.

Error: resource not found

Solution: Ensure the resource type is correct and exists in the cluster.

Command Breakdown

What each part is doing

kubectl: Base Command; The executable that performs this operation. Here it runs Kubectl before the shell applies any redirect operators.
<verb>: verb; The value supplied for verb.
<resource>: resource; The value supplied for resource.
-n: n| namespace; The value supplied for n| namespace.
<namespace>: namespace; The value supplied for namespace.
-n: Command Option; Tool-specific option used by this command invocation.

How To Run

Execution path

Step 1
Replace {{verb}} with the action you want to check (e.g., get, create).
Step 2
Replace {{resource}} with the Kubernetes resource type (e.g., pods, deployments).
Step 3
Optionally specify the namespace using -n or --namespace followed by the namespace name.
