Creation of your first instance

===============================

Instance creation

-----------------

Now that we created our cube, we can create an instance to view our

configuration to simplify things ::

  cubicweb-ctl create -c all-in-one mycube myinstance

.. note::

  Please note that we created a new cube for a demo purpose but

  you could have use an existing cube available in our standard library

  such as blog or person for example.

A serie of questions will be prompted to you, the default answer is usually

sufficient. You can anyway modify the configuration later on by editing

configuration files. When a user/psswd is requested to access the database

please use the login you create at the time you configured the database

(:ref:`ConfigurationPostgres`).

It is important to distinguish here the user used to access the database and the

user used to login to the cubicweb application. When an instance starts, it uses

the login/psswd for the database to get the schema and handle low level

transaction. But, when :command:`cubicweb-ctl create` asks for a manager

login/psswd of `CubicWeb`, it refers to the user you will use during the

development to administrate your web application. It will be possible, later on,

to use this user to create others users for your final web application.

Instance administration

-----------------------

start / stop

~~~~~~~~~~~~

When this command is completed, the definition of your instance is

located in :file:`~/etc/cubicweb.d/myinstance/*`. To launch it, you just type ::

  cubicweb-ctl start -D myinstance

The option `-D` specify the *debug mode* : the instance is not running in

server mode and does not disconnect from the termnial, which simplifies debugging

in case the instance is not properly launched. You can see how it looks by

defined when you created the instance.

To shutdown the instance, Crtl-C in the terminal window is enough.

If you did not use the option `-D`, then type ::

  cubicweb-ctl stop myinstance

This is it! All is settled down to start developping your data model...
