A terminal UI that compresses daily Docker and Docker Compose workflows into a single interactive panel, built to replace the VS Code Docker extension for editors like Zed that lack one.

TextualDocker

Overview

undock is a terminal-first Docker control panel. It provides a terminal UI for the most common container tasks — rebuild, logs, exec, restart — without requiring a GUI or IDE extension.

Problem

Zed has no Docker extension. In VS Code, the Docker extension compresses rebuild, log-streaming, exec, and cleanup into a structured UI with single clicks. Without an equivalent, container-heavy development in Zed requires verbose CLI commands, lowering discoverability and raising cognitive load across the inner loop of rebuild-check-restart-repeat.

Approach

Built a Textual-based terminal UI that surfaces the most-used Docker and Compose commands in an interactive panel with visible key bindings, so nothing needs to be memorized.

Constraints

  • Must be editor-agnostic and not tied to any IDE extension API
  • Must work over SSH and in headless environments — no UI
  • Must surface command hints in-UI — too many shortcuts to memorize

Key Decisions

Build a CLI rather than wait for a native Zed Docker extension

Vibe coding a first version is fast enough to validate the idea without a large time investment.

Alternatives: Wait for an official Zed Docker extensionUse shell aliases in .zshrc or .bashrc

Workflow compression over feature parity

The goal is not to replicate the full Docker API. The goal is to cover the 20% of extension features used 80% of the time — rebuild, logs — and make them fast to invoke.

Result & Impact

Reduces friction for container-heavy development outside VS Code, enabling migration to faster editors without losing the Docker control surface. Editor-agnostic by design, so it survives future IDE migrations.

Learnings

  • Workflow compression delivers more value than feature parity. Covering the most common actions well beats covering all actions adequately.
  • Editor-agnostic tooling has a durability advantage: it works regardless of which editor you are currently using.
