# go-k8s-btop
|
||||||
|
|
||||||
|
A terminal-based Kubernetes resource monitor, similar to htop/btop but for Kubernetes pods.
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
- List all pods in specified namespaces with their statuses
|
||||||
|
- Monitor CPU and memory usage with graphical bars
|
||||||
|
- Display logs from starting or restarting pods
|
||||||
|
- Color-coded status indicators (green for running, yellow for pending, red for failed)
|
||||||
|
- Live updates with configurable refresh interval
|
||||||
|
- Keyboard shortcuts for navigation and display options
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
Clone the repository and build:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
git clone https://github.com/matst80/go-k8s-btop.git
|
||||||
|
cd go-k8s-btop
|
||||||
|
go build
|
||||||
|
```
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
```
|
||||||
|
./go-k8s-btop [options]
|
||||||
|
```
|
||||||
|
|
||||||
|
### Command-line Options
|
||||||
|
|
||||||
|
- `-kubeconfig string`: Path to the kubeconfig file (default: "~/.kube/config")
|
||||||
|
- `-namespaces string`: Comma-separated list of namespaces to monitor (default: "dev,home,cart")
|
||||||
|
- `-refresh int`: Refresh interval in seconds (default: 5)
|
||||||
|
|
||||||
|
### Keyboard Shortcuts
|
||||||
|
|
||||||
|
- `q` or `Ctrl+C`: Quit the application
|
||||||
|
- `r`: Manually refresh the display
|
||||||
|
- `h`: Toggle help screen
|
||||||
|
|
||||||
|
## Examples
|
||||||
|
|
||||||
|
Monitor default namespaces with default settings:
|
||||||
|
```bash
|
||||||
|
./go-k8s-btop
|
||||||
|
```
|
||||||
|
|
||||||
|
Monitor specific namespaces:
|
||||||
|
```bash
|
||||||
|
./go-k8s-btop -namespaces=kube-system,default
|
||||||
|
```
|
||||||
|
|
||||||
|
Use a custom refresh interval:
|
||||||
|
```bash
|
||||||
|
./go-k8s-btop -refresh=10
|
||||||
|
```
|
||||||
|
|
||||||
|
## Requirements
|
||||||
|
|
||||||
|
- Go 1.18 or higher
|
||||||
|
- A valid kubeconfig with access to the Kubernetes API
|
||||||
|
- Metrics API enabled in your Kubernetes cluster (for CPU/Memory usage)
