dockviz-cli

A real-time Docker environment dashboard for your terminal.

---

dockviz-cli is an interactive terminal UI (TUI) that gives you a live view of your Docker environment — containers, resource usage, networks, and images — without leaving the terminal.

Run dockviz --demo to try it right now without Docker.

Features

• Real-time stats — CPU and memory usage refreshed every 2 seconds
• Network topology — ASCII graph of container-to-network relationships
• Image browser — local images with tags and sizes
• Container control — start / stop / delete containers with a single key press
• CPU sparkline — 10-point unicode bar graph (▁▂▃▄▅▆▇█) per container row
• Real-time log streaming — l key opens a scrollable live log view
• Image pull progress — dockviz pull <image> shows per-layer download bars
• Detail view — per-container info (ID, image, ports, status)
• Demo mode — --demo flag runs with simulated data, no Docker required

Quick Start

Prerequisites

• Go 1.22+
• Docker Desktop or Docker Engine (not required for --demo)

Install from source

git clone https://github.com/0206pdh/dockviz-cli.git
cd dockviz-cli
go build -o dockviz .

Run

# Connect to your local Docker daemon
./dockviz

# Preview with simulated data — no Docker required
./dockviz --demo

Keyboard Shortcuts

Key	Action
q / Ctrl+C	Quit
Tab	Switch panel (Containers → Networks → Images)
↑ / k	Move up
↓ / j	Move down
Enter	Open container detail
Esc	Go back
s	Start / Stop selected container
d	Delete selected container (with confirmation)
l	Open live log stream
r	Force refresh

Architecture

This project follows The Elm Architecture (TEA) as implemented by Bubble Tea:

main.go
  └── cmd.Execute()          ← Cobra CLI (--demo flag)
        └── tui.Start()
              ├── docker.NewClient()      ← Docker SDK / DemoClient
              └── tea.NewProgram(model)   ← Bubble Tea event loop
                    ├── Init()   → first data fetch + ticker
                    ├── Update() → key events, ticks, Docker responses
                    └── View()   → Lip Gloss styled terminal output
