Hello, World

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



The template for Django applications.



Django Application

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



Pipenv

^^^^^^



.. code:: sh



  pip install pipenv



or



.. code:: sh



  apt install pipenv



or



.. code:: sh



  brew install pipenv



Configuration

^^^^^^^^^^^^^



.. code:: sh



  cp .env.example.sh .env



Then either



.. code:: sh



  set -a; . .env; set +a



or



.. code:: sh



  export READ_ENV=.env



Running from working tree

^^^^^^^^^^^^^^^^^^^^^^^^^



.. code:: sh



  pip install pipenv

  pipenv install --dev

  pipenv run ./manage.py migrate

  pipenv run ./manage.py runserver



Installing

^^^^^^^^^^



.. code:: sh



  pipenv run ./setup.py bdist_wheel

  virtualenv -ppython3 /opt/pdns-gui

  bash --rcfile /opt/pdns-gui/bin/activate

  pip install dist/pdns_gui-*.whl



Running from package

^^^^^^^^^^^^^^^^^^^^



.. code:: sh



  PATH=/opt/pdns-gui/bin:$PATH

  pdns-gui migrate

  pdns-gui runserver



Database

--------



SQLite

^^^^^^



By default this project uses SQLite databases stored in ``./run/db`` directory.



MySQL

^^^^^



*Debian / Ubuntu*



.. code:: sh



  sudo apt-get install mysql-server mysql-client libmysqlclient-dev



or:



.. code:: sh



  sudo apt-get install mariadb-server mariadb-client libmariadbclient-dev-compat



*Configuration*



.. code:: sh



  cat << END | mysql -v

  CREATE DATABASE hello_world CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

  CREATE DATABASE django CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

  END

  cat > .my.cnf << END

  [client:hello_world]

  host = localhost

  port = 3306

  user = root

  password =



  [client:django]

  host = localhost

  port = 3306

  user = root

  password =

  END



*Python*



.. code:: sh



  pipenv install mysqlclient



PostgreSQL

^^^^^^^^^^



*Debian / Ubuntu*



.. code:: sh



  sudo apt-get install postgresql libpq-dev

  sudo sed -i '/^# TYPE/alocal all hello md5' /etc/postgresql/*/main/pg_hba.conf

  sudo service postgresql reload

  sudo -i -u postgres createuser --createdb --pwprompt hello

  sudo -i -u postgres createdb --encoding=UTF8 --owner=hello hello

  echo 'localhost:*:hello:hello:hello' >> ~/.pgpass

  echo 'localhost:*:test_hello:hello:hello' >> ~/.pgpass

  chmod 600 ~/.pgpass

  psql -U hello hello -c '\dt'



*Python*



.. code:: sh



  pipenv install psycopg2



systemd

-------



The application can be started using embedded Werkzeug HTTP server that can be

started as a systemd service.



.. code:: sh



  adduser --system --group pdns-gui



``/etc/systemd/system/pdns-gui.service``



.. code:: ini



  [Unit]

  Description=Django Hello World

  After=network.target



  [Service]

  WorkingDirectory=/opt/pdns-gui

  User=pdns-gui

  Group=pdns-gui

  EnvironmentFile=/opt/pdns-gui/.env

  ExecStart=/opt/pdns-gui/bin/pdns-gui runserver --noreload --insecure --threaded --no-color 0.0.0.0:8000

  KillMode=process

  Restart=on-failure



  [Install]

  WantedBy=multi-user.target



Then



.. code:: sh



  systemctl enable pdns-gui.service

  systemctl start pdns-gui.service

  journalctl -f -u pdns-gui.service



Project management

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



Repository

^^^^^^^^^^



This repository uses "relaxed" git-flow layout: main leading branch is

``develop`` and the latest stable code is ``master``. The feature and bugfix

branches are merged into ``develop``. Changes from `develop` and `master` are

fast-forwarded.



Versioning

^^^^^^^^^^



This project does not use semantic versioning (it makes sense for libraries).

Version number schema is: ``MAJOR.YYYYMMDD.REL``, where ``MAJOR`` is a real

project version and ``REL`` is a number for a release in the same day.



Version number is stored in a ``pdns_gui/__init__.py`` file (main

project module) and provides ``VERSION`` and ``__version__`` symbols, ie.:



.. code:: python



  VERSION = (0, 20190516, 1)

  __version__ = '.'.join(map(str, VERSION))



Pipelines

^^^^^^^^^



This project provides a configuration for GitLab pipelines that test a project,

build artifacts and tag the latest stable working version.



Pipelines run only for branches (no tags):



* In feature and bugfix branches run tests

* In `develop` branch build, export and test artifacts

* In `master` branch merge and tag arfifacts repo and tag main app repo



Main App repository

^^^^^^^^^^^^^^^^^^^



GitLab pipelines use read-write access to main and artifacts repository using

private SSH deployment key stored in ``SSH_PRIVATE_KEY`` variable.



This repository has changed the default branch to ``develop`` and enabled SSH

deployment key with read-write access.



Artifacts repository

^^^^^^^^^^^^^^^^^^^^



Artifacts are stored in separate Git repository with git-lfs support.



Artifacts repository uses the same layout as a main app repository

(``develop``, ``master``, tags).



Initialization for artifacts repository was:



.. code:: sh



  git init

  git remote add origin $GIT_REPO_PACKAGES_URL

  git checkout -b develop

  git lfs install

  git lfs track "*.gz"

  git lfs track "*.whl"

  git lfs track "*.zip"

  git add .gitattributes

  git commit -m git-lfs .

  git push origin develop



Then the default branch was changed to ``develop``.



This repository has disabled CI pipelines and enabled SSH deployment key with

read-write access.



Offline installation

^^^^^^^^^^^^^^^^^^^^



Artifacts repository allows to install all packages in offline mode.



.. code:: sh



  git clone $GIT_REPO_PACKAGES_URL .packages

  virtualenv -ppython3 /opt/pdns-gui

  bash --rcfile /opt/pdns-gui/bin/activate

  pip install --no-index --find-links .packages --upgrade --requirement dist-requirements.txt



Testing

^^^^^^^



Testing pipieline is started after each push to any branch.



It is possible to run GitLab testing pipeline without GitLab runner using

``docker-compose``.



.. code:: sh



  cd .gitlab-ci

  docker-compose up --abort-on-container-exit --exit-code-from test --force-recreate



Release

^^^^^^^



Release pipeline is started after fast-forward from ``develop`` to ``master``.

This pipeline do fast-forward in artifacts repository and make a new tag based

on a current package version.
