Modular SDK

You use Modular SDK to create, configure, and manage common entities, such as:

• Customers;
• Tenants;
• TenantSettings;
• Regions;
• Applications;
• Parents;

Prerequisites

• Python 3.10+ required

Building distribution archives

• Make sure you have the latest version of PyPA’s build installed: python3 -m pip install --upgrade build
• Run the command form the same directory where pyptoject.toml is located: python3 -m build
• This command should output a lot of text and once completed should generate two files in the dist directory:

dist/
    modular_sdk-{version}.tar.gz
    modular_sdk-{version}-py3-none-any.whl

Installation

• pip install modular-sdk

Usage

To use Modular SDK, you must import, configure and indicate which service or services you're going to use:

from modular_sdk.modular import Modular

modular_sdk = Modular()

parent_service = modular_sdk.parent_service()
tenant_service = modular_sdk.tenant_service()

For services that aren't tied to the service_mode configuration, you can use ModularServiceProvider:

from modular_sdk.modular import ModularServiceProvider

modular_sdk = ModularServiceProvider()

thread_local_storage_service = modular_sdk.thread_local_storage_service()

For now, Modular provides 3 ways of DB access. Depends on the way of database connection, different sets of env variables must be set:

1. Onprem, Mongodb:
   modular_service_mode: docker,
   modular_mongo_user: $MONGO_USER,
   modular_mongo_password: $MONGO_PASSWORD,
   modular_mongo_url: $MONGO_URL,
   modular_mongo_db_name: $MONGO_DB_NAME,
   modular_mongo_srv: True, # Optional
   Alternatively, instead of specifying modular_mongo_user, modular_mongo_password,
   modular_mongo_url, and modular_mongo_srv, you can use:
   modular_mongo_uri: $MONGO_URI # Format: mongodb+srv://<USER>:<PASSWORD>@<URL>/
2. SaaS, DynamoDB (cross-account access):
   modular_service_mode: saas # Optional
   modular_assume_role_arn: $ASSUME_ROLE_ARN
3. SAAS, DynamoDB (same AWS account):
   modular_service_mode: saas # Optional

Alternatively, you can pass these parameters (fully or partially) on initialization:

from modular_sdk.modular import Modular

modular_sdk = Modular(modular_service_mode='docker',
                      modular_mongo_user='MONGO_USER',
                      modular_mongo_password='MONGO_PASSWORD',
                      modular_mongo_url='MONGO_URL',
                      modular_mongo_db_name='DB_NAME')

# initialize some services
application_service = modular_sdk.application_service()
parent_service = modular_sdk.parent_service()

More examples

Example 1: List Maestro Customers

from modular_sdk.modular import Modular

# initializing application service
customer_service = Modular().customer_service()

# listing available customers 
customers = customer_service.list()

# printing customer names
for customer in customers:
   print(customer.name)

Example 2: Update Maestro Application

from modular_sdk.modular import Modular

# initializing application service
application_service = Modular().application_service()

# extracting application by id
application = application_service.get_application_by_id(
   application_id="$APP_ID")

# updating application description
description_to_set = 'Updated application description'
application_service.update(application=application,
                           description=description_to_set)

# saving updated application
application_service.save(application=application)

Example 3: Delete Maestro Parent

from modular_sdk.modular import Modular

# initializing parent service
parent_service = Modular().parent_service()

# extracting parent by id
parent = parent_service.get_parent_by_id(parent_id="$PARENT_ID")

# deleting parent
parent_service.mark_deleted(parent=parent)
