Installation

Enable this module in your doom! block.

This module assumes docker, docker-compose and docker-machine binaries are installed and accessible from your PATH.

Optionally, this module also uses the following programs:

• docker-langserver (for LSP users): $ npm install -g dockerfile-language-server-nodejs

TODO Usage

🔨 This module's usage documentation is incomplete. Complete it?

Docker control

Use M-x docker, select a resource, and then mark or unmark items using the following keybindings (for more marking possibilities, check out 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

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-machine: create, env, restart, rm, start, stop
• docker-compose: build, config, create, down, exec, logs, pull, push, remove, restart, run, start, stop, up You can also enter dired or open a file inside a container or volume.

TRAMP

Offers the TRAMP method docker to access running containers:

C-x C-f /docker:$USER@$CONTAINER:/path/to/file

$USER	the user that you want to use (optional)
$CONTAINER	the id or name of the container

TODO Configuration

🔨 This module's configuration documentation is incomplete. Complete it?

Popups

Thanks to magit-popup, all the popups default arguments can be customized. For example, here is how to customize the arguments for docker-image-run-popup:

(setq docker-image-run-arguments '("-i" "-t" "--rm"))

or inside a use-package declaration:

(use-package! docker
  :bind ("C-c d" . docker)
  :custom (docker-image-run-arguments '("-i" "-t" "--rm")))

Other useful variables

Variable	Description	Default
docker-command	The docker binary to use	docker
docker-container-default-sort-key	Sort key for docker containers	("Image")
docker-container-shell-file-name	Shell to use when entering containers	/bin/bash
docker-image-default-sort-key	Sort key for docker images	("Repository")
docker-machine-default-sort-key	Sort key for docker machines	("Name")
docker-network-default-sort-key	Sort key for docker networks	("Name")
docker-run-as-root	Run docker as root	nil
docker-volume-default-sort-key	Sort key for docker volumes	("Driver")

Completion in Dockerfiles

By default, the keyword completion function detects the docker-compose version of the current buffer and suggests the appropriate keywords.

You can change the candidates offered by the backend by customizing docker-compose-keywords.

Troubleshooting

Report an issue?

Tramp hangs on Alpine container

Busyboxes built with the ENABLE_FEATURE_EDITING_ASK_TERMINAL config option also send escape sequences, which tramp-wait-for-output doesn't ignore correctly. This was fixed in TRAMP upstream and is available since TRAMP 2.3.

For older versions of TRAMP you can dump docker-tramp-compat.el in your load-path somewhere and add the following to $DOOMDIR/config.el to overwrite tramp-wait-for-output with the patch applied:

(after! tramp
  (require 'docker-tramp-compat))
