Running into permission issues when trying to run Kubernetes (K8S) can be a common problem, especially for newcomers to the platform. In this article, I will guide you through the process of troubleshooting and resolving the "running K8S reports no permission" error.

### Understanding the Issue
When you encounter the "running K8S reports no permission" error, it typically means that the user or service account attempting to interact with the Kubernetes cluster does not have the necessary permissions to perform the desired actions. This can happen for various reasons, such as incorrect RBAC configurations, missing cluster roles, or insufficient privileges granted to the user.

### Troubleshooting Steps
To address the permission issue when running K8S, we need to follow a series of steps to diagnose and rectify the problem. Below is a table summarizing the steps we will take:

| Step | Description |
|------|-------------|
| 1 | Check Kubernetes Configuration |
| 2 | Verify User Permissions |
| 3 | Review RBAC Policies |
| 4 | Grant Necessary Permissions |

Now let's dive into each step and see what actions we need to take along with the corresponding code snippets:

### Step 1: Check Kubernetes Configuration
Ensure that your Kubernetes configuration file is correctly set up to communicate with the cluster. You can do this using the following command:

```bash
kubectl config view
```

This command will display the current Kubernetes configuration settings, including the cluster, user, and context being used.

### Step 2: Verify User Permissions
Check if the user attempting to interact with the cluster has the necessary permissions. You can list the current users and their roles using the following command:

```bash
kubectl auth can-i --list
```

This command will provide a list of actions that the current user can perform within the cluster.

### Step 3: Review RBAC Policies
Review the Role-Based Access Control (RBAC) policies defined within the cluster to ensure that they align with the desired permissions. You can view the RBAC policies with the following command:

```bash
kubectl get clusterrolebindings
```

This command will list all the cluster role bindings, which define the permissions granted to different users or service accounts.

### Step 4: Grant Necessary Permissions
If the user does not have the required permissions, you will need to grant them by creating appropriate RBAC roles or role bindings. For example, you can create a cluster role binding with the necessary permissions using the following YAML manifest:

```yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: my-cluster-role-binding
subjects:
- kind: User
name: your-username
apiGroup: rbac.authorization.k8s.io
roleRef:
kind: ClusterRole
name: cluster-admin
apiGroup: rbac.authorization.k8s.io
```

Apply the above manifest using the following command:

```bash
kubectl apply -f cluster-role-binding.yaml
```

Replace `your-username` with the actual username and adjust the permissions as needed based on your requirements.

By following these steps and making the necessary adjustments, you should be able to resolve the "running K8S reports no permission" issue and successfully run Kubernetes operations without encountering permission errors. Remember to always review and update permissions as needed to maintain a secure and efficient Kubernetes environment.
