;;; Commentary:
|
|
|
|
;; Allows Tramp access to environments provided by Docker and similar
|
|
;; programs.
|
|
;;
|
|
;; ## Usage
|
|
;;
|
|
;; Open a file on a running Docker container:
|
|
;;
|
|
;; C-x C-f /docker:USER@CONTAINER:/path/to/file
|
|
;; C-x C-f /dockercp:USER@CONTAINER:/path/to/file
|
|
;;
|
|
;; or Podman:
|
|
;;
|
|
;; C-x C-f /podman:USER@CONTAINER:/path/to/file
|
|
;; C-x C-f /podmancp:USER@CONTAINER:/path/to/file
|
|
;;
|
|
;; Where:
|
|
;; USER is the user on the container to connect as (optional).
|
|
;; CONTAINER is the container to connect to.
|
|
;;
|
|
;; "docker" and "podman" are inline methods, "dockercp" and "podmancp"
|
|
;; are out-of-band methods.
|
|
;;
|
|
;;
|
|
;;
|
|
;; Open file in a Kubernetes container:
|
|
;;
|
|
;; C-x C-f /kubernetes:[CONTAINER.]POD[%NAMESPACE]:/path/to/file
|
|
;;
|
|
;; Where:
|
|
;; POD is the pod to connect to.
|
|
;; CONTAINER is the container to connect to (optional).
|
|
;; By default, the first container in that pod will
|
|
;; be used.
|
|
;; NAMESPACE is the namespace to be used (optional).
|
|
;;
|
|
;;
|
|
;;
|
|
;; Open a file on an existing Toolbox container:
|
|
;;
|
|
;; C-x C-f /toolbox:CONTAINER:/path/to/file
|
|
;;
|
|
;; Where:
|
|
;; CONTAINER is the container to connect to (optional).
|
|
;;
|
|
;; If the container is not running, it is started. If no container is
|
|
;; specified, the default Toolbox container is used.
|
|
;;
|
|
;;
|
|
;;
|
|
;; Open a file on an existing Distrobox container:
|
|
;;
|
|
;; C-x C-f /distrobox:CONTAINER:/path/to/file
|
|
;;
|
|
;; Where:
|
|
;; CONTAINER is the container to connect to.
|
|
;;
|
|
;; If the container is not running, it is started.
|
|
;;
|
|
;;
|
|
;;
|
|
;; Open a file on a running Flatpak sandbox:
|
|
;;
|
|
;; C-x C-f /flatpak:SANDBOX:/path/to/file
|
|
;;
|
|
;; Where:
|
|
;; SANDBOX is the running sandbox to connect to.
|
|
;; It could be an application ID, an instance ID, or a PID.
|
|
;;
|
|
;;
|
|
;;
|
|
;; Open a file on a running Apptainer instance:
|
|
;;
|
|
;; C-x C-f /apptainer:INSTANCE:/path/to/file
|
|
;;
|
|
;; Where:
|
|
;; INSTANCE is the running instance to connect to.
|
|
;;
|
|
;;
|
|
;;
|
|
;; Open a file on a running systemd-nspawn container:
|
|
;;
|
|
;; C-x C-f /nspawn:USER@CONTAINER:/path/to/file
|
|
;;
|
|
;; Where:
|
|
;; USER is the user on the container to connect as (optional)
|
|
;; CONTAINER is the container to connect to
