This project joins some useful scripts designed to speed up project development.

Main scripts are:

configuration.py

This script generates a configparser.configuration instance.

Configuration load from different sources:

AWS Systems manager parameter store

• Given that AWS CLI is configured and credentials loaded

configuration = load_config('ssm',environment)

SSM variable key must have format: /$environment/$section and value in json format

Local file

configuration = load_config('file',environment, file_name)

File expected in standard INI file structure.

[ddbb]
host=localhost
port=3306
username=root
password=changeit

Environment variables.

configuration = load_config('env',environment, projectname)

Variables should have the following format: $projectname_$environemnt_$sectionname

MYPROJECT_PRO_DDBB_HOST=localhost
MYPROJECT_PRO_DDBB_PORT=3306
MYPROJECT_PRO_DDBB_USERNAME=root
MYPROJECT_PRO_DDBB_PASSWORD=changeit

Database.py

Database connection and query execution

database = Database.ofConfiguration(configuration)

To execute query, use method Database.run_query

records = database.run_query('SELECT * FROM table WHERE mycolumn = %s AND myothercolumn = '%s',('value1', 'value2' ))

Pagination is supported using class database.Page:

page_number = 1
page_size = 50
page = Database.Page(page_number, page_size)
records = database.run_query('SELECT * FROM table WHERE mycolumn = %s AND myothercolumn = '%s', ('value1', 'value2' ), page)

alerts.py

Alert sending, via AWS simple email service.
