docker-tramp.el offers a TRAMP method for Docker containers.

NOTE: docker-tramp.el relies in the docker exec command. Tested with docker version 1.6.x but should work with versions >1.3. Podman also works.

NOTE: Similar functionality is built-in to Emacs from version 29 onwards, so perhaps you don't need this package any more.

Offers the TRAMP method docker to access running containers

C-x C-f /docker:user@container:/path/to/file

where
  user           is the user that you want to use inside the container (optional)
  container      is the id or name of the container

If you container is hosted on vm.example.net:

/ssh:[email protected]|docker:user@container:/path/to/file

If you need to run the docker command as, say, the root user:

/sudo:root@localhost|docker:user@container:/path/to/file

Busyboxes built with the ENABLE_FEATURE_EDITING_ASK_TERMINAL config option send also escape sequences, which tramp-wait-for-output doesn't ignores correctly. Tramp upstream fixed in 98a5112 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 your init.el, which overwrites tramp-wait-for-output with the patch applied:

    (require 'docker-tramp-compat)

This is a known issue with Tramp, but is not a bug so much as a poor default setting. Adding tramp-own-remote-path to tramp-remote-path will make Tramp use the remote's PATH environment varialbe.

    (add-to-list 'tramp-remote-path 'tramp-own-remote-path)
