issues in command

[utkarsh232005]

command not working giving only dummy output:
afftected comands:

1. kdm health all
2. kdm watch
3. kdm logs [pod name]

Followup the watch is now working but the health is still not working as expected and logs one also

Coding Plan

Summary

• Leverage existing, proven data-fetching functions (getRunningPods(), getRunningContainers()) rather than creating new API calls
• Follow the established command pattern demonstrated in show.ts for consistent code structure
• Use existing UI utilities (renderTable, logger) for output formatting
• Implement auto-detection for the logs command to provide seamless user experience across Docker and Kubernetes resources

Design Choices

Design Choice 1: Watch command scope clarification

Options Considered:

1. Assume watch is broken and rewrite it
2. Assume watch works but needs enhancement (e.g., showing health/alert status)
3. Assume watch works and exclude from scope

Chosen Option: 3

Rationale: Code analysis confirms watch delegates to a fully-implemented React/Ink dashboard with real API calls. The ticket may have included it in error or due to a separate runtime issue. Focus implementation on the clearly broken health and logs commands, plus the root banner fix.

Design Choice 2: Logs command target identification

Options Considered:

1. Require a flag (e.g., --pod or --container) to specify the resource type
2. Auto-detect by querying both Docker and Kubernetes, using the first match
3. Add subcommands (kdm logs pod <name>, kdm logs container <name>)

Chosen Option: 2

Rationale: Auto-detection provides the best user experience and aligns with the existing show command pattern which handles multiple resource types seamlessly. Query Kubernetes pods first, then Docker containers as fallback.

Implementation Steps

Phase 1: Implement Health Command

This phase replaces the stub health command with real functionality that fetches and displays health status for Kubernetes pods and Docker containers using existing data-fetching infrastructure.

Task 1: Add Health Data Fetching Logic

Implement the core health checking functionality that retrieves real status information from both Kubernetes and Docker.

• Update src/commands/health.ts to import and call getRunningPods() from src/kubernetes/pods.ts
• Import and call getRunningContainers() from src/docker/containers.ts
• Support target values: all (both sources), pods (K8s only), containers (Docker only)
• Extract relevant health fields: name, status/state, restarts, and derive a health indicator (healthy/unhealthy based on status)

Task 2: Add Health Output Rendering

Display the fetched health data in a formatted table using the existing table rendering utility.

• Use renderTable() from src/ui/table.ts to display health information
• Define table columns: Name, Type (Pod/Container), Status, Health, Restarts
• Color-code health status (green for healthy states like Running, red for failed/unhealthy states)
• Handle empty results gracefully with an informative message
• Handle API errors (Docker not running, K8s unreachable) with clear error messages using logger.error()

🤖 Prompt for AI agents

Replace the stub `health` command in `src/commands/health.ts` with real data
fetching and table rendering.

- Import `getRunningPods()` from `src/kubernetes/pods.ts` and
`getRunningContainers()` from `src/docker/containers.ts`
- Based on the command target argument, fetch data from the appropriate source:
  - `all`: fetch from both Kubernetes and Docker
  - `pods`: fetch from Kubernetes only
  - `containers`: fetch from Docker only
- For each fetched resource, extract the relevant health fields: name,
status/state, restarts, and derive a health indicator (healthy or unhealthy
based on status)
- Import and use `renderTable()` from `src/ui/table.ts` to display the results
with columns: Name, Type (Pod/Container), Status, Health, Restarts
- Color-code health status: green for healthy states (e.g., Running), red for
failed/unhealthy states
- Handle empty results gracefully with an informative message
- Handle API errors (Docker not running, K8s unreachable) with clear error
messages using `logger.error()`

Phase 2: Implement Logs Command

This phase replaces the stub logs command with real functionality that fetches and streams logs from either Kubernetes pods or Docker containers.

Task 1: Add Resource Detection Logic

Implement logic to determine whether the provided name corresponds to a Kubernetes pod or Docker container.

• Update src/commands/logs.ts to query getRunningPods() and check if any pod name matches the input
• If no pod match, query getRunningContainers() to check for a container name match
• Store the matched resource type and relevant metadata (namespace for pods, container ID for Docker)
• Return an appropriate error if the name doesn't match any resource

Task 2: Implement Kubernetes Pod Log Fetching

Add functionality to retrieve logs from Kubernetes pods using the existing K8s client.

• Use getK8sApi() from src/kubernetes/client.ts to obtain the CoreV1Api instance
• Call api.readNamespacedPodLog(name, namespace) with the pod name and its namespace
• Output the log content directly to console
• Handle errors (pod not found, unauthorized, API unreachable) with descriptive messages

Task 3: Implement Docker Container Log Fetching

Add functionality to retrieve logs from Docker containers using dockerode.

• Use the docker client from src/docker/client.ts
• Call docker.getContainer(id).logs() with appropriate options (stdout, stderr, tail)
• Stream or output the log content to console
• Handle errors (container not found, Docker not running) with descriptive messages

- Call `docker.getContainer(id).logs()` with appropriate options (stdout,
stderr, tail)
- Stream or output the log content to console
- Handle errors (container not found, Docker not running) with descriptive
messages

Phase 3: Fix Root Banner Health Display

This phase replaces the hardcoded mocked unhealthy services count with a real value derived from actual pod and container status data.

Calculate Real Unhealthy Count

Replace the hardcoded "Unhealthy Services: 0 (Mocked)" with actual health aggregation.

• Update src/commands/root.ts to fetch data from getRunningPods() and getRunningContainers()
• Count resources in unhealthy states (e.g., pods in CrashLoopBackOff, Failed, ImagePullBackOff; containers in exited/dead state with non-zero exit codes)
• Replace line 59's hardcoded output with the computed unhealthy count
• Remove the "(Mocked)" label from the output
• Handle fetch failures gracefully (show "N/A" or skip the line if data unavailable)

Research

This is a Node.js CLI tool (kdm) built with Commander.js for command parsing, using @kubernetes/client-node for Kubernetes API interactions and dockerode for Docker operations. The project has established patterns: data fetching functions in src/kubernetes/pods.ts and src/docker/containers.ts, table rendering via src/ui/table.ts, and a consistent command registration pattern. The show.ts command demonstrates a fully-implemented reference pattern for fetching and displaying real data. The Ink-based WatchDashboard component already polls live data every 3 seconds, showing the infrastructure for real-time monitoring exists.
