Installation

The recommended way to install docker.el is through MELPA.

Here is a example use-package configuration:

(use-package docker
  :ensure t
  :bind ("C-c d" . docker))

Quickstart

Use M-x docker, select a resource then mark or unmark items using the following keybindings (for more marking possibilities, check out https://github.com/politza/tablist):

Binding	Description
?	List actions
l	Configure listing
m	Mark item
u	Unmark item
t	Toggle marks
U	Unmark all
s	Sort
* r	Mark items by regexp
<	Shrink column
>	Enlarge column
C-c C-e	Export to csv

Then select an action and follow the instructions.

Supported commands

• docker container: attach, cp, diff, inspect, kill, logs, pause, rename, restart, rm, start, stop, unpause
• docker image: inspect, pull, push, rm, run, tag
• docker network: rm
• docker volume: rm
• docker context: ls, use
• docker-compose: build, config, create, down, exec, logs, pause, pull, push, remove, restart, run, start, stop, unpause, up

You can also enter dired or open a file inside a container or volume.

Customizations

Thanks to transient, all the transients arguments can be set temporarily or permanently. See https://magit.vc/manual/transient/Saving-Values.html#Saving-Values for more information.

There are also hidden items (e.g on M-x docker where you could specify the host or TLS settings), see https://magit.vc/manual/transient/Enabling-and-Disabling-Suffixes.html for more information.

Here is a list of other customizations you can set:

Variable	Description	Default
docker-command	The docker binary to use	docker
docker-compose-command	The docker-compose binary to use	docker-compose
docker-container-columns	Columns definition for containers	/bin/sh
docker-container-default-sort-key	Sort key for containers	("Image")
docker-container-shell-file-name	Shell to use when entering containers	/bin/sh
docker-container-tramp-method	Tramp prefix when connecting to containers	docker
docker-image-columns	Columns definition for images	Too complex to show
docker-image-default-sort-key	Sort key for images	("Repository")
docker-image-run-default-args	Base arguments to use for docker run	("-i" "-t" "--rm")
docker-network-columns	Columns definition for networks	Too complex to show
docker-network-default-sort-key	Sort key for networks	("Name")
docker-pop-to-buffer-action	Action for docker-utils-pop-to-buffer	nil
docker-run-as-root	Runs docker as root when enabled	nil
docker-run-async-with-buffer-function	Function used to run programs with buffers	Too complex to show
docker-show-messages	If non-nil message docker commands	t
docker-show-status	If non-nil compute status	t
docker-volume-columns	Columns definition for volumes	Too complex to show
docker-volume-default-sort-key	Sort key for volumes	("Driver")

Changing the default arguments for docker run

You can match on the repository name for an image to customize the initial infix arguments via docker-image-run-custom-args:

(add-to-list
   'docker-image-run-custom-args
   `("^postgres" ("-e POSTGRES_PASSWORD=postgres" . ,docker-image-run-default-args)))

So when docker run is called on an image whose repository name matches the regular expression ^postgres, the option "-e POSTGRES_PASSWORD=postgres" will appear as set along with the defaults specified by docker-image-run-default-args.

Vterm support

If vterm is installed, it'll be used for any commands that needs a running buffer (for example docker run, docker logs, etc).
