Run Tuleap
==========

.. NOTE:: Please read and follow instructions of both :ref:`clone-tuleap` and
    :ref:`install-docker` sections before executing this one.

Mandatory development dependencies
----------------------------------

You will need the following tools to develop on Tuleap, please refer to their
respective documentation for installation instructions:

- make
- `scss-lint <https://github.com/brigade/scss-lint/>`_
- `nodejs <https://nodejs.org/en/>`_ >= v6.x
- `npm <https://docs.npmjs.com/>`_ >= v6.0
- `composer <https://getcomposer.org/>`_

   .. IMPORTANT:: By default, composer installs itself in the local directory as ``composer.phar``.

        However we require that ``composer`` command is available in your executable path.
        This can be done by executing the following command during the installation steps:

        ``sudo php composer-setup.php --filename=composer --install-dir=/usr/local/bin``


First start of Tuleap
---------------------

.. code-block:: bash

    $ cd /path/to/tuleap
    $ make composer
    $ npm run build
    $ make dev-setup
    $ make start
    $ make post-checkout

.. NOTE:: docker will download base images for mysql, tuleap, … Please be patient!

Then you need to know the IP address of the web container, with ``docker inspect tuleap-web | grep '"IPAddress"'`` and
edit (as root) the ``/etc/hosts`` file: ``172.17.0.4    tuleap-web.tuleap-aio-dev.docker``.

Now open your browser and go to https://tuleap-web.tuleap-aio-dev.docker/. You should see the homepage of your Tuleap
instance. You can connect with ``admin`` account, the password will be given by ``make show-passwords``.

And voila, your server is up and running!

Descriptions of commands
------------------------

* ``make dev-setup``: This command generates some needed passwords (mysql, ldap,
  …) and creates data containers. Those data containers are used as volumes to
  persist data (files, db, …). This command needs to be run only once.
* ``make start``: This command is a wrapper around ``docker-compose up``. It
  starts 3 containers: ``web`` for the front end, ``ldap`` to manage users in an
  OpenLDAP server, and ``db`` for the mysql server.

  You can issue the following command in order to check that all containers are started:

  .. code-block:: bash

    $ docker ps --format "{{.ID}}: {{.Names}} — {{.Image}} {{.Ports}}"
    149428f796ea: tuleap-web — enalean/tuleap-aio-dev:nodb 22/tcp, 80/tcp, 443/tcp
    7cd1e645b3a9: tuleap_ldap_1 — enalean/ldap:latest 389/tcp, 636/tcp
    9d026f381fbf: tuleap_db_1 — mysql:5.5 3306/tcp

* ``make post-checkout``: Install npm dependencies, generate the javascript and CSS files to be used by the browser,
  deploy gettext translation... You need to run this command everytime you switch a branch.

.. NOTE:: Docker images are read-only, and every modification to the OS will be
    lost at reboot. If you need to add/change anything and make it persistant, fork
    and amend the `Dockerfile <https://hub.docker.com/r/enalean/tuleap-aio-dev/>`_.
    Everything but the OS (tuleap config, database, user home) is saved in docker volumes held by ``tuleap_data``.

Pro-tips
--------

If you need to connect to the server you can run:

.. code-block:: bash

    $ docker exec -ti tuleap-web bash
    $> export TERM=linux

And if you need to connect to the database:

.. code-block:: bash

    $ docker run -it --link tuleap_db_1:mysql --rm mysql sh -c 'exec mysql -h"$MYSQL_PORT_3306_TCP_ADDR" -P"$MYSQL_PORT_3306_TCP_PORT" -uroot -p"$MYSQL_ENV_MYSQL_ROOT_PASSWORD" tuleap'

Troubleshooting
---------------

If your browser cannot manage to reach https://tuleap-web.tuleap-aio-dev.docker/:

* Check that all containers are up and running with ``docker ps``. If it is not
  the case, inspect logs ``docker-compose logs db`` or ``docker-compose logs web``.
* Check that apache serves files by executing a ``wget -O -
  http://localhost/`` once connected to the ``web`` container (see
  :ref:`protips`). If you see a long html output that contains typical Tuleap
  homepage, then it means that there is an issue with the dns. (You may need to ``yum install wget`` first).
* Check that you can resolve tuleap-web.tuleap-aio-dev.docker: ``dig
  '*.docker'``, ``dig '*.tuleap-aio-dev.docker'`` and ``dig
  'tuleap-web.tuleap-aio-dev.docker'`` should return a suitable answer
  (typically ``172.17.42.4`` for the web container, but it may vary).

If you don't receive email, this is because we configured postfix to not deliver emails by default. You may need to manually add the emails you use for your development:

.. code-block:: bash

    $ docker exec -ti tuleap-web bash
    $> vi /data/etc/email_whitelist # enter your email
    $> ./whitelist_emails.sh
    $> service postfix reload
