Tramp helm interface for ssh server and docker and vagrant

M-x helm-tramp

Display server list from your ~/.ssh/config with helm interface.

Filter by helm.

You can connect your server with tramp.

Selecting the list with sudo will lead to the server as root. Selecting the list of '/sudo:root@localhost:/' will open file at localhost as root.

You can edit your server's nginx.conf on your emacs!

If you are using docker-tramp, docker is also supplemented. If you are using vagrant-tramp, vagrant is also supplemented.

You can edit docker container on your emacs!

helm-tramp-quit

When you finish editing nginx.conf you clean the tramp buffer with helm-tramp-quit command.

• Emacs 24.3 or higher
• helm 2.0 or higher

You can install helm-tramp.el from MELPA with package.el (M-x package-install helm-tramp).
You can install docker-tramp.el from MELPA with package.el (M-x package-install docker-tramp).
If you use Emacs version >= 29.0.60 then docker-tramp is no longer necessary as this functionality is built-in to Tramp.
You can install vagrant-tramp.el from MELPA with package.el (M-x package-install vagrant-tramp).

I recommend you are going to install exec-path-from-shell.

(setq tramp-default-method "ssh")
(define-key global-map (kbd "C-c s") 'helm-tramp)

(add-hook 'helm-tramp-pre-command-hook '(lambda () (global-aggressive-indent-mode 0)
				     (projectile-mode 0)
				     (editorconfig-mode 0)))
(add-hook 'helm-tramp-quit-hook '(lambda () (global-aggressive-indent-mode 1)
			      (projectile-mode 1)
			      (editorconfig-mode 1)))

Setting hook that turn off slow extensions when you execute helm-tramp. Setting hook that turn on extensions when you execute helm-tramp-quit command.

If you don't make a backup files and lockfiles at remote server, it will be saved faster.

(setq make-backup-files nil)
(setq create-lockfiles nil)

Besides ~/.ssh/config, you can add connections manually.

(setq helm-tramp-custom-connections '(/ssh:domain|sudo:user@localhost:/))

Example when adding more than two connections manually.

(setq helm-tramp-custom-connections '(/ssh:domain|sudo:user@localhost:/ /ssh:domain2|sudo:user@localhost:/))

If the shell of the server is zsh it is recommended to connect with bash.

(eval-after-load 'tramp '(setenv "SHELL" "/bin/bash"))

If you want to specify the user name to connect with docker-tramp.

(setq helm-tramp-docker-user "username")

If you want to specify multiple user name list to connect with docker-tramp.

(setq helm-tramp-docker-user '("username1" "username2" "username3" "username4"))

If you want to change initial directory when connecting with /sudo:root@localhost:.

(setq helm-tramp-localhost-directory "/root")
