 # Labels Tower
-# Système d'étiquettage utilisé par le projet Piscine
 
+Some python code for management of labels within a Flask application.
+For demo pupose, one must define either `LT_CFG=Voiture` or `LT_CFG=CodingPool`.
 
-## News 
-* Création de la BDD
-* Possibilité d'ajouter des labels et des alias dans un formatage particulier (les labels sont liés ensembles).
+## Directories
 
-## A venir
-* Affichage des labels parent puis de ses enfants quand on clique dessus (50%).
+Most directories have their own `README.md`.
+* `labelstower` : main code, i.e. a blueprint for Flask.
+* `docker` : anything for building docker images with all the needed externals.
+* `dist` : where we build and store wheel distributions of the main labelstower code.
+* `test/instance` : where we initialize a test sqlite database.
+* `test/demo` : web demo application.
+* `test/scripts` : various command-line test.
 
-## Etapes
-Affichage des labels => Ajouts de tutos => Affichages des tutos
-(Avant la fin de la semaine si possible)
+## Demonstration from scratch, with Docker
 
-## Installation
-    $> sudo apt-get install python3 python3-pip virtualenv
-    $> virtualenv labelsTower
-    $> cp -R app/ labelsTower/
-    #Dans labelsTower/
-    $> source bin/activate
-	$> sudo python3 -m pip install flask
-	$> export FLASK_APP=app/labelsTower.py
+With the help of Docker :
+1. Build the dev Docker image : `docker/build_externals.sh`
+1. Build the labelstower distribution : `docker/run_externals.sh dist/build.sh`
+1. Build the demo Docker image : `docker/build_latest.sh` (it includes the above distribution)
+1. Initialize a database : `docker/run_latest.sh instance/init_db.sh`
+1. Starts the flask server : `docker/run_latest.sh`

docker/README.md

+
+LAST MINUTE : if you want to run such a container with no command,
+that is with the default flask command, then one must define `LT_CFG``
+environment variable before, so that docker defines `LABELSTOWER_ENV=demo.config.Config${LT_CFG}`
+for the need of the demo web application.
+
+# Directory for Docker images and utility scripts
+
+* The "externals" flavor of scripts produce a `labelstower:externals` image, containing only the external software needed for the development of labelstower.
+* The "lastest" flavor of scripts produce a `labelstower:latest` image, containing an installation of the latest labelstower package found in `../dist/`.
+
+## Requirements
+
+Testing the LabelsTower code thanks to Docker requires only Docker to be installed. Yet, if one wants also to take profit of the utility scripts provided in the current directory, the command `/usr/bin/env bash` (used as a shebang in the scripts) must return a valid bash shell.
+
+## Scripts
+
+The commands below are meant to be launched within the `docker` directory :
+* `build_externals.sh` : build a local image for development.
+* `run_externals.sh` : start a container with the previous image, mounting `..` as `/work`. by default, it is starting the flaks server, but can be used with optional other commands.
+
+Note : as one can see in the `Dockerfile_externals` file, Flask is started with the option `--host 0.0.0.0`, which is necessary so that the http server, running potentially on a small virtual machine (at least on MacOS and Windows), can be seen from the real local machine.
+
+## Usages of `run_externals.sh`
+
+The `run.sh` script can be be given optional additional commands :
+* `run_externals.sh` : starts a flask web server.
+* `run_externals.sh dist/build.sh` : build a new wheel in `dist`.
+* `run_externals.sh instance/pip_init_db.sh` : install the wheel and initialize a database in `instance`.
+
+Note : the `run.sh` script starts a docker container with the option `--rm`, meaning when the container command ends, the container is automatically removed, and anything which was not stored in the `/work` directory (a mount of `..`) will be lost. This typically concerns commands such as `pip3 install ...`, whose affects root internal directoris of the container.
