Project description

AWS Serverless Application Repository - Python

A Python library with convenience helpers for working with the AWS Serverless Application Repository.

Installation

Simply use pip to install the library:

pip install serverlessrepo

Basic Usage

The serverlessrepo module provides a simple interface for publishing applications and managing application permissions. To get started, import the serverlessrepo module:

import serverlessrepo

Publish Applications

publish_application(template, sar_client=None)

Given an AWS Serverless Application Model (SAM) template, it publishes a new application using the specified metadata in AWS Serverless Application Repository. If the application already exists, it updates metadata of the application and publishes a new version if specified in the template.

For example:

import boto3
import yaml
from serverlessrepo import publish_application

sar_client = boto3.client('serverlessrepo', region_name='us-east-1')

with open('template.yaml', 'r') as f:
    template = f.read()
    # if sar_client is not provided, we will initiate the client using region inferred from aws configurations
    output = publish_application(template, sar_client)

    # Alternatively, pass parsed template as a dictionary
    template_dict = yaml.loads(template)
    output = publish_application(template_dict, sar_client)

The output of publish_application has the following structure:

{
    'application_id': 'arn:aws:serverlessrepo:us-east-1:123456789012:applications/test-app',
    'actions': ['CREATE_APPLICATION'],
    'details': {
        'Author': 'user1',
        'Description': 'hello',
        'Name': 'hello-world',
        'SemanticVersion': '0.0.1',
        'SourceCodeUrl': 'https://github.com/hello'}
    }
}

There are three possible values for the actions field:

  • ['CREATE_APPLICATION'] - Created a new application.
  • ['UPDATE_APPLICATION'] - Updated metadata of an existing application.
  • ['UPDATE_APPLICATION', 'CREATE_APPLICATION_VERSION'] - Updated metadata of an existing application and created a new version, only applicable if a new SemanticVersion is provided in the input template.

details has different meaning based on the actions taken:

  • If a new application is created, it shows metadata values used to create the application.
  • If application is updated, it shows updated metadata values.
  • If application is updated and new version is created, it shows updated metadata values as well as the new version number.

update_application_metadata(template, application_id, sar_client=None)

Parses the application metadata from the SAM template and only updates the metadata.

For example:

import boto3
import yaml
from serverlessrepo import update_application_metadata

sar_client = boto3.client('serverlessrepo', region_name='us-east-1')

with open('template.yaml', 'r') as f:
    template = f.read()
    application_id = 'arn:aws:serverlessrepo:us-east-1:123456789012:applications/test-app'
    # if sar_client is not provided, we will initiate the client using region inferred from aws configurations
    update_application_metadata(template, application_id, sar_client)

    # Alternatively, pass parsed template as a dictionary
    template_dict = yaml.loads(template)
    update_application_metadata(template_dict, application_id, sar_client)

Manage Application Permissions

make_application_public(application_id, sar_client=None)

Makes an application public so that it's visible to everyone.

make_application_private(application_id, sar_client=None)

Makes an application private so that it's only visible to the owner.

share_application_with_accounts(application_id, account_ids, sar_client=None)

Shares the application with specified AWS accounts.

Examples

import boto3
from serverlessrepo import (
    make_application_public,
    make_application_private,
    share_application_with_accounts
)

application_id = 'arn:aws:serverlessrepo:us-east-1:123456789012:applications/test-app'
sar_client = boto3.client('serverlessrepo', region_name='us-east-1')

# Share an application publicly
make_application_public(application_id, sar_client)

# Make an application private
make_application_private(application_id, sar_client)

# Share an application with other AWS accounts
share_application_with_accounts(application_id, ['123456789013', '123456789014'], sar_client)

Development

  • Fork the repository, then clone to your local:
    • git clone https://github.com/<username>/aws-serverlessrepo-python.git
  • Set up the environment: make init
    • It installs Pipenv to manage package dependencies. Then it creates a virtualenv and installs dependencies from Pipfile (including dev).
  • Install new packages: pipenv install [package names]
    • Pipenv will automatically update Pipfile and Pipfile.lock for you.
    • Add new dependencies to setup.py install_requires if they are needed for consumers of this library.
  • Verify that everything works: make build
    • You can run make test separately to verify that tests pass.
    • Check code style with make flake and make lint.
  • Make code changes, run all verifications again before sending a Pull Request: make pr
