Emacs integration for Docker!
Supports docker containers, images, volumes, networks, docker-machine and docker-compose.
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))
Use M-x docker, select a resource then 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 popup instructions.
- 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.
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
:ensure t
:bind ("C-c d" . docker)
:custom (docker-image-run-arguments '("-i" "-t" "--rm")))
You can also customize these using M-x customize-variable.
Variable | Description | Default |
---|---|---|
docker-command | The docker binary to use (podman is also supported) | 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") |
The following configuration is required (some of it can probably be simplified by using https://github.com/purcell/exec-path-from-shell).
(setenv "PATH" (concat (getenv "PATH") ":/usr/local/bin"))
(setq exec-path (append exec-path '("/usr/local/bin")))
;; Use "docker-machine env box" command to find out your environment variables
(setenv "DOCKER_TLS_VERIFY" "1")
(setenv "DOCKER_HOST" "tcp://10.11.12.13:2376")
(setenv "DOCKER_CERT_PATH" "/Users/foo/.docker/machine/machines/box")
(setenv "DOCKER_MACHINE_NAME" "box")
This is necessary and useful if you use docker-machine
.
Notice though that there is also a native MacOS Docker implementation
(now called Docker Desktop)
which does not depend on VirtualBox and which does not require these tweaks.
They are very welcome, either as suggestions or as pull requests by opening tickets on the issue tracker.
