# CDT - Cluster Diagnose Tool

A powerful CLI tool for diagnosing Kubernetes clusters and bare-metal servers.

## Features

### K8s Mode
- `pod <name>` - Diagnose specific Pod issues
- `net [pod] <target>` - Network connectivity test (host mode or pod-in mode)
- `node [target]` - Node diagnostic (local or remote via SSH)
- `lb <service>` - Load balancer / Service check
- `events [pod]` - View K8s events
- `nodes` - Node status overview
- `scan` - Quick scan for abnormal Pods

### Bare Metal Mode
- `dns` - Check DNS configuration
- `net <target>` - Network connectivity test

## Quick Start

```bash
# Download binary
chmod +x cdt
./cdt

# Select mode
1. K8s Cluster
2. Bare Metal

# K8s mode commands
> pod my-app
> net my-app google.com
> node 192.168.1.100
> lb my-service
> scan
```

## Installation

### Linux
```bash
# Download from releases or build from source
curl -L -o cdt https://gitee.com/CodeGrok/cdt/releases
chmod +x cdt
sudo mv cdt /usr/local/bin/
```

### Build from Source
```bash
git clone git@gitee.com:CodeGrok/cdt.git
cd cdt
cargo build --release
./target/release/cdt
```

## Configuration

CDT automatically searches for kubectl and kubeconfig:

### kubectl Path
1. PATH environment variable
2. `/usr/local/bin/kubectl`
3. `which kubectl`

### kubeconfig Path
1. `KUBECONFIG` environment variable
2. `/etc/kubernetes/admin.conf`
3. `/etc/kubernetes/kubelet-config.yaml`
4. `/etc/kubernetes/kubelet.conf`
5. `~/.kube/config`

If no kubeconfig is found, CDT will prompt you to enter the path.
