# Dockerfile for rapid developing Elnode based web-application.

```sh

docker-compose build

docker-compose up

```

Then `app/app.el` loaded and you can access this web application via `lvh.me:8081`.

# Interactive overwrite web application

This container's emacs will be started as daemon mode, so you can eval eny forms by host machine via TCP protocol.

Which means you can overwrite your web application's feature without restarting server or re-build docker container.

```elisp

;; First, eval this progn to use TCP connection.

(progn

  (require 'server)

  (setq server-host "0.0.0.0")

  (setq server-port "1234")

  (setq server-use-tcp t)

  (setq server-name "emacs_server")

  ;; You need to set "serverd" dir to find auth file

  (setq server-auth-dir "path-to-serverd-dir"))

;; Eval any forms in emacs daemon in container

(server-eval-at "emacs_server" '(+ 1 10)) ;; => 11

;; Overwrite request handler

(server-eval-at "emacs_server"

                '(defun my-test-handler (httpcon)

                   "Demonstration function"

                   (elnode-http-start httpcon 200 '("Content-type" . "text/html"))

                   (elnode-http-return httpcon (format "
New handler!
%s
" (emacs-version)))))


```

# for VirtualBox users

If you use OS X or Windows, you must be using VirtualBox's VM to run docker daemon, via docker-machine.

Assuming the VM's name is `default`(It's default name if you use docker toolbox), you need to set portforwarding like following:

```sh

VBoxManage modifyvm "default" --natpf1 "tcp-port1234,tcp,,1234,,1234"

VBoxManage modifyvm "default" --natpf1 "udp-port1234,udp,,1234,,1234"

VBoxManage modifyvm "default" --natpf1 "tcp-port8081,tcp,,8081,,8081"

VBoxManage modifyvm "default" --natpf1 "udp-port8081,udp,,8081,,8081"

```

# Deployment

## sloppy.io

Host your docker container at [sloppy.io](http://sloppy.io).

```bash

sloppy start sloppy.json --var domain:YOUR_FAVORITE_NAME.sloppy.zone

```
