NoOra a database deployment tool.
Welcome to Noora
Noora is a deployment tool for automating the database deployment cycle. It allows you to organize your database structure, do versioning on your data model, set up environments and generate self-contained Python packages that can deploy your structure to a server.
Noora was created with the DevOps paradigm in mind; especially when as a team you manage many database models it enables you to standardize your DDL and streamline development, testing, acceptance and deployment in production.
NOTE: This project is currently split across two branches, where Noora 1.1.0 provides MySQL and MSSQL support using Python 2 and 3 and Noora 1.0.2 supports Oracle and MySQL using Python 2 only. This documentation describes Noora >= 1.1.
Noora is released under the Apache License 2.0.
To install Noora, you can install from pip, a release from Github or from source::
# Install from PyPi $ pip install noora # Install from github $ pip install git+https://email@example.com#egg=noora # Clone and install from source $ git clone https://github.com/janripke/noora/ $ cd noora # Checkout the release you want to use # (NOTE: the master branch is NOT guaranteed to be stable!) $ git checkout tags/1.2.8 $ pip install .
We'll set up a MySQL project, so first make sure to create a user and database for your project:
$> mysql -u root mysql> create database acme; mysql> create user apps@'localhost' identified by 'apps'; mysql> grant all on acme.* to apps@'localhost'; mysql> -- This is currently required to be able to drop functions and procedures, to be fixed mysql> grant select, delete on mysql.proc to apps@'localhost'; mysql> flush privileges;
Then, on the command line create your project:
$ mynoora generate -t=mysql Host [localhost]: Port : Database name: acme Database username: apps Database password: Repeat for confirmation: Initial project version [1.0.0]: version 1.0.0 created.
Add a table and some data to your newly created project:
$ echo "CREATE TABLE hello ( value VARCHAR(128) );" > acme-db/create/acme/ddl/tab/hello.sql $ echo "INSERT INTO hello SET value='world';" > acme-db/create/acme/dat/hello.sql
Now, let's deploy the project and see what happens:
$ cd acme-db $ mynoora create -h=localhost creating database 'acme' on host 'localhost' using environment 'dev' /home/niels/tmp/acme-db/create/acme/ddl/tab/application_properties.sql /home/niels/tmp/acme-db/create/acme/ddl/tab/hello.sql /home/niels/tmp/acme-db/create/acme/ddl/fct/get_property.sql /home/niels/tmp/acme-db/create/acme/ddl/trg/application_properties_bi.sql /home/niels/tmp/acme-db/create/acme/ddl/trg/application_properties_bu.sql /home/niels/tmp/acme-db/create/acme/ddl/idx/application_properties.sql /home/niels/tmp/acme-db/create/acme/dat/hello.sql /home/niels/tmp/acme-db/create/acme/dat/version.sql /home/niels/tmp/acme-db/create/acme/dat/dev/environment.sql database 'acme' created.
You can verify that the table you added along with some default data was deployed, and that the current version of your database model is 1.0.0 in the 'dev' environment:
$ mysql -uapps -p acme Enter password: mysql> select * from hello; +--------+ | value | +--------+ | world; | +--------+ 1 row in set (0.00 sec) mysql> select get_property('application.version'); +-------------------------------------+ | get_property('application.version') | +-------------------------------------+ | 1.0.0 | +-------------------------------------+ 1 row in set (0.00 sec)
That's it! To learn more about Noora projects, check out http://noora.readthedocs.org/getting-started. For now, you can clear out your database like this::
$ mynoora drop -h=localhost dropping database 'acme' on host 'localhost' using environment 'dev' /home/niels/projects/noora/noora/plugins/mysql/drop/vw/drop_views.sql /home/niels/projects/noora/noora/plugins/mysql/drop/tab/drop_foreign_keys.sql /home/niels/projects/noora/noora/plugins/mysql/drop/prc/drop_procedures.sql /home/niels/projects/noora/noora/plugins/mysql/drop/fct/drop_functions.sql database 'acme' dropped.
Note that this does not actually drop the database itself, rather it removes all objects, including views and procedures.
