WhatTheDock

WhatTheDock is a terminal app for working with Docker containers and Compose stacks.

It is meant for the stuff you do all the time:

• see what is running
• check logs and problems
• start, stop, restart, edit, clone, delete, or recreate containers
• manage local and remote Docker hosts
• keep a small library of Compose files you can edit, save, and make live

It uses Docker's normal defaults. If docker ps works on your machine, whatthedock should have a decent shot at working too.

This is still an early project, but the main workflow is usable.

Install

Install the latest release:

curl -fsSL https://raw.githubusercontent.com/allisonhere/whatthedock/main/scripts/install.sh | sh

The installer downloads the latest release binary, checks that it runs, and puts it in /usr/local/bin. If that is not writable, it uses ~/.local/bin. Set INSTALL_DIR if you want another location.

Build from source:

go install github.com/allisonhere/whatthedock/cmd/whatthedock@latest

Run it:

whatthedock

Run the demo if you do not have Docker handy:

whatthedock --demo

Finding Things

There are two search helpers:

• Press Ctrl+K for the command palette. Type what you want, then press Enter.
• Press ? for Help. Inside Help, press / and type a word like catalog, logs, delete, or systems.

That is usually faster than remembering every key.

Main Keys

Key	What it does
j / k or Up / Down	Move around
Tab / Shift+Tab	Move between panes
Enter	Open/select the focused item
Space	Expand/collapse a stack row; pause/resume logs in Logs
/	Filter containers and stacks; in Logs, filter log lines
r	Refresh Docker state
s	Start/stop the selected container
Alt+r	Restart the selected container
n	Create a container or Compose service
m	Edit the selected service; on a stack row, edit the whole stack
C	Clone the selected container/service
D	Delete the selected container/service; on a stack row, delete the whole stack
u	Pull latest image and recreate in place
e	Open a shell in the selected running container
c	Copy selected details
o	Open a selected port, mount, or Compose path
q / Ctrl+C	Quit

Logs, Problems, And Stats

Key	What it does
l	Show logs
L	Expand logs across most of the screen
e / w / i / a in Logs	Show errors, warnings, info, or all log lines
f / End in Logs	Jump to the end and follow live output
Home / PgUp / PgDn in Logs	Move through log history
Esc in Logs	Clear the active log filter
p	Show problems
a in Problems	Ask the configured AI provider to analyze the selected problem
g	Show stats graphs

AI analysis is opt-in. It only runs when you press a in Problems, and only after you configure a provider in Settings.

Create And Edit

Press n to create something new. Press m to edit what is selected.

Useful keys in the create/edit form:

Key	What it does
[ / ]	Switch between standalone, Compose service, and Compose stack modes
Up / Down / Tab	Move between fields
h / l or Left / Right	Change choices or move the cursor in text fields
Enter	Move to the next field; on the Compose file field, browse
Ctrl+O	Browse for a Compose file
Ctrl+Y	Edit the Compose YAML directly
Ctrl+P	Open the small create/edit Compose catalog picker
Ctrl+S	Validate or save changes
Ctrl+Enter / Alt+Enter	Show the final confirmation
Esc / q	Cancel/close

Compose support is practical, not magical:

• A single-service Compose file can be edited as a service.
• A multi-service Compose file is treated as a stack.
• Editing a stack row edits the whole Compose file.
• Editing one service in a stack asks whether you mean that service or the whole stack.
• Local and SSH systems both work for Compose reads, writes, and docker compose runs.

Compose Catalog

The Compose catalog is a library of Compose files.

Use it when you want to keep a Compose file around, edit it safely, add notes, or later make it live on a local or remote Docker host.

Open it from the command palette:

Ctrl+K -> Curate Compose files

Catalog keys:

Key	What it does
Tab	Switch between Library, Live, and Unused views
j / k	Move selection
f	Filter entries
A	Add a draft from a URL or path
B	Browse for a Compose file and add it as a draft
N	Start a blank draft
Enter / l	Preview an entry
e	Edit an entry
c	Create a runnable draft from a live stack
S	Save a live stack as a draft
M / p	Make the selected entry live
s	Change status: draft, live, or archived
m	Toggle missing/unused review
n / t	Edit note or tags
a	Archive or unarchive
D	Delete the catalog entry

Notes are saved in catalog metadata and mirrored into a WhatTheDock comment block at the top of the Compose file. That way the note travels with the YAML instead of only living in the app.

Make Live asks for a destination path, shows conflicts, writes the Compose file to the active local or SSH system, then runs docker compose up -d.

Other Curators

Open these from Ctrl+K:

• Curate Docker images
• Curate Docker networks
• Curate Docker volumes

The keys are the same in each one:

Key	What it does
j / k	Move through the list
Space	Select a removable item
r	Reload
d	Delete selected items
y / Enter	Confirm deletion
n / Esc	Cancel

In-use items are shown, but they cannot be selected for removal.

Systems

Press S to manage Docker systems.

You can:

• switch between systems
• test a connection
• add a local or SSH system
• edit a system
• delete an inactive system

System keys:

Key	What it does
Enter	Switch to the selected system
t	Test the selected system
a	Add a system
e	Edit a system
d	Delete an inactive system
Ctrl+S while editing	Save
Esc	Cancel/close

Supported system types:

• local: Docker on this machine, using normal Docker defaults unless you set a host.
• ssh: a tunnel to a remote Docker socket.

SSH auth modes:

• config/agent: use your normal SSH config, keys, and agent.
• keychain: store the SSH password in the OS keychain, not in settings.json.
• password prompt: let ssh ask for the password each time.

Settings live in your platform config directory. On Linux that is usually:

~/.config/whatthedock/settings.json

Settings

Open Settings with , or Ctrl+,.

Settings include:

• theme and graph style
• refresh interval
• default activity pane
• whether to start in Dashboard
• editor mode
• AI provider/model/API key/base URL
• app activity log options
• update checks

Press Ctrl+S to save.

If you export a provider's normal API key environment variable, that wins over a stored key:

• ANTHROPIC_API_KEY
• OPENAI_API_KEY
• GEMINI_API_KEY

Dashboard

Press d for the Dashboard.

It shows a quick view of the host, running containers, CPU, memory, network activity, and problems.

Key	What it does
j / k	Move through rows
Enter	Open the highlighted container
p	Jump to Problems
Esc / q / d	Close Dashboard

Mouse wheel and click work where the terminal supports them.

Updates

WhatTheDock can check GitHub releases for updates.

When an update is available, it asks before installing. If you say yes, it downloads the matching release asset, verifies its signature, replaces the running binary, and restarts.

The release signing key is baked into the app. Unsigned or invalid updates are rejected.

Development

Run the normal checks:

make check

That runs:

• gofmt -l .
• go test ./...
• go test -race ./...
• go vet ./...
• go build -buildvcs=false ./...

Run locally from source:

go run -buildvcs=false ./cmd/whatthedock

Run the demo from source:

go run -buildvcs=false ./cmd/whatthedock --demo

Build a binary:

go build -buildvcs=false -o whatthedock ./cmd/whatthedock
./whatthedock

Print the version:

whatthedock --version

More detail:

• Container and Compose creation workflow
• Engineering handoff

Release

The release helper is a small TUI:

go run ./cmd/release

It shows the branch, latest tag, commit log, and diff since the last tag. It can build, sign, tag, push the tag, and create the GitHub release.

Use a dry run first:

go run ./cmd/release -dry-run

Release binaries are signed with an ed25519 signature. Generate the signing key once with:

go run ./cmd/release -genkey

Keep the private key in WHATTHEDOCK_SIGNING_KEY. Do not commit it.

What It Uses TideUI For

WhatTheDock uses TideUI for the shared terminal UI pieces: panes, borders, rows, overlays, themes, and status bars.
