tetcd 0.1.0

A TUI application for managing etcd key-value stores (v2 and v3)

tetcd

A keyboard-driven terminal UI for browsing and managing etcd key-value stores. Supports both the etcd v2 HTTP API and the etcd v3 gRPC-gateway API, and feels like a file manager for your etcd namespace.

Features

• Browse the etcd key space as a hierarchical tree (using / as a separator)
• View values in a side panel
• Add, edit, and delete keys
• Add and recursively delete directories
• Lazy loading: children are fetched only when a node is expanded
• Layered configuration via CLI flags, environment variables, or a config file
• Confirmation prompts before destructive operations
• Works with both etcd v2 and v3

Installation

Install from PyPI with your tool of choice:

# pipx (recommended for CLI tools)
pipx install tetcd

# uv
uv tool install tetcd

# pip
pip install tetcd

Requires Python 3.12 or newer.

Usage

# Launch the TUI (defaults: v3, localhost:2379)
tetcd

# Connect to a specific etcd
tetcd --host my-etcd.internal --port 2379 --api v3

# Use the v2 API
tetcd --api v2

# Show version
tetcd --version

Keybindings

Key	Action
a	Add key
d	Add directory
D	Delete
e	Edit value
r	Refresh tree
q	Quit

Configuration

Configuration is layered (highest priority first):

1. CLI flags — --host, --port, --api
2. Environment variables — prefix TETCD_, e.g. TETCD_ETCD_HOST=my-etcd
3. settings.toml — committed defaults
4. .secrets.toml — local overrides and credentials (gitignored)

Default settings.toml:

[default]
etcd_version = "v3"
etcd_host    = "localhost"
etcd_port    = 2379
log_level    = "INFO"

Development

The project uses uv for dependency management, Ruff for linting and formatting, ty for type checking, and pytest for tests.

# Install dependencies
uv sync

# Run the TUI from source
uv run tetcd

# Run tests
uv run pytest

# Lint and format
uv run ruff check src tests
uv run ruff format src tests

# Type check
uv run ty check

Dev container

Open the project in VS Code and choose "Reopen in Container". The container starts an etcd 3.5 service on port 2379 and pre-sets TETCD_ETCD_HOST=etcd, so uv run tetcd connects out of the box.
