K9s

Step 1: Use K9s to view the status of the deployment.

Step 2: Drill down into the pods associated with the deployment to check their status and logs.

Step 3: Identify any error messages or crash loops in the pod logs.

Step 4: Use K9s to restart the failing pods or scale the deployment if needed.

Step 1: Use K9s to view the resource utilization of nodes and pods.

Step 2: Identify pods or nodes with high CPU or memory usage.

Step 3: Adjust resource requests and limits for pods to optimize resource allocation.

Step 4: Scale the deployment or add more nodes to the cluster if necessary.

Step 1: Use K9s to view RBAC rules such as cluster roles and role bindings.

Step 2: Identify the permissions associated with specific users, groups, or service accounts.

Step 3: Troubleshoot authorization issues by verifying that users have the necessary permissions.

Step 4: Modify RBAC rules to grant or revoke permissions as needed.

Step 1: Use K9s to initiate a benchmark test against an HTTP service.

Step 2: Configure the benchmark test with parameters such as the number of requests and concurrency level.

Step 3: Analyze the benchmark results to identify performance bottlenecks.

Step 4: Adjust resource requests and limits or optimize the application code to improve performance.

Step 1: Use K9s to select a specific Kubernetes resource, such as a deployment or service.

Step 2: Use the resource graph traversal feature to view the related resources, such as pods, replica sets, and services.

Step 3: Identify any dependencies or relationships that may be causing issues.

Step 4: Take corrective action to resolve any dependency-related problems.
