SSMEnv allows you to read parameters from AWS Parameter Store and operate on results as on dictionary.

Installation

You have to have boto3 installed then you can just run:

pip install ssmenv

Read parameters

Reading parameters is as simply as initialising class object.

from ssmenv import SSMEnv

ssmenv = SSMEnv(("/service/my-service", "/resource/dynamodb"))

# Accessing parameters
debug = ssmenv["SERVICE_MY_SERVICE_DEBUG"]

# As it's dictionary we can also:

# 1. Get list of all loaded parameter's names
list(ssmenv.keys())

# 2. Get list of all loaded parameter's values
list(ssmenv.values())

# and so on.

Populate os.environ

You can hide use of SSMEnv by using os.environ dict.

import os
from ssmenv import SSMEnv

os.environ = {**os.environ, **SSMEnv("/service/my-service")}

Remove common prefixes

Accessing your parameters through whole namespaces can sometimes be not convenient especially if you have very long names.

Hence why you can use prefixes parameter, to make your code cleaner.

from ssmenv import SSMEnv

ssmenv = SSMEnv(("/service/my-service",), prefixes=("/service/my-service",))
ssmenv["DEBUG"]
