Usage

Ducker is comprised of a set of pages, each of which display specific information about and/or allow interaction with the docker containers and images on the host system.

Top level pages can be navigated to with commands, input via the prompt. Pages can be interacted with using actions; these are input via hotkey inputs.

A legend for common global hotkey inputs is displayed at the bottom of the screen; one for contextual (eg different on each page) hotkey inputs are displayed in the top right.

Commands

The following commands are supported:

Command	Aliases	Description
images	image	Open the Images top level page
containers	container	Open the Containers top level page
volumes	volume	Open the Volumes top level page
networks	network	Open the Networks top level page
help	h	Open the Help page
quit	q	Close the application

Actions

Containers

The following actions are available on the Containers page:

Ctrl+d	Delete the currently selected container
a	Exec into the currently selected container (if container is running)*
l	View the logs for the currently selected container
r	Run the currently selected container
s	Stop the currently selected container

*NB: exec currently only supports containers with bash installed. The intention is that this will be updated to provide a user option.

Images

The following actions are available on the Images page:

Hotkey	Action
Ctrl+d	Delete the currently selected image
Alt+d	Toggle dangling images
d	Describe the currently selected image

d	Describe the currently selected volume

Networks

The following actions are available on the Networks page:

Hotkey	Action

⚠️ Network deletion isn't entirely complete: A failed deletion currently results in a yes/no modal telling you that it couldn't be deleted. There is no difference between the yes and no results. This is due to the current modal story and a quick and dirty hack to get them set up. Once a generic modal exists this will be patched up!

Hotkey	Action
Esc	Return to the containers page
