::   ejabberd Docker installer for Windows
::   -------------------------------------
::                                    v0.3
::
:: This batch script downloads an ejabberd docker image
:: and setups a docker container to run ejabberd.

::
:: 1. Download and install Docker:
::
::    If you use Windows 10, download Docker Desktop from:
::      https://www.docker.com/
::
::    If you use Windows 7 or 8, download Docker Toolbox from:
::      https://github.com/docker/toolbox/releases
::    After installation, run Docker Quickstart Installer
::

::
:: 2. Edit those options:

:: Directory where your ejabberd deployment files will be installed
:: (configuration, database, logs, ...)
::
:: In Windows 10 you can configure the path:

set INSTALL_DIR_WINDOWS10=C:\ejabberd

:: In older Windows, not configurable, it will be installed in:
:: C:\Users\%USERNAME%\ejabberd

:: Please enter the desired ejabberd domain name.
:: The domain is the visible attribute that is added to the username
:: to form the Jabber Identifier (for example: user@example.net).
:: This computer must be known on the network with this address name.
:: You can later add more in conf/ejabberd.yml

set HOST=localhost

:: Please enter the administrator username for the current
:: ejabberd installation. A Jabber account with this username
:: will be created and granted administrative privileges.
:: Don't use blankspaces in the username.

set USER=admin

:: Please provide a password for that new administrator account

set PASSWORD=

:: By default this downloads 'latest' ejabberd version,
:: but you can set a specific version, for example 21.01

set VERSION=latest

:: This tells docker what ports ejabberd will use.
:: You can later configure them in conf/ejabberd.yml

set PORTS=5180 5222 5269 5443

::
:: 3. Now save this script and run it.
::

::
:: 4. When installation is completed:
::
:: If using Windows 10, open Docker Desktop and you can:
::
:: - (>) START the ejabberd container
:: - Enter WebAdmin: click the ([->]) OPEN IN BROWSER button
:: - To try ejabberdctl, click the (>_) CLI button, then: bin/ejabberdctl
:: - ([]) STOP the ejabberd container
::
:: If using an old Windows, open Kitematic and you can:
::
:: - START the ejabberd container
:: - Open your configuration, logs, ... in Settings > Volumes
:: - Enter WebAdmin in Settings > Hostname/Ports > click on the 5180 port
:: - Try ejabberdctl in EXEC, then: bin/ejabberdctl
:: - STOP the ejabberd container
::
:: You can delete the container and create it again running this script,
:: the configuration and database are maintained.
