Python settings/environment variables via Consul key/value store

cevaris, updated 🕥 2022-12-26 19:48:07

EnvConsul

Python environment variable wrapper around Consul key/value storage. When instantiated, EnvConsol fetches the key value data for a defined service from Consul. These environment variables are retrievable via the path they were stored in Consul.

For example if we insert a database name for specific services in Consul

shell curl -X PUT -d 'db.sqlite3' \ http://localhost:8500/v1/kv/web00.django.test/databases/default/name EnvConsul can fetch and be queried like so

python import envconsul ENV_CONSUL = envconsul.EnvConsul('web00.django.test') DATABASE_NAME = ENV_CONSUL.get_str('/databases/default/name')

Features

Retrieve Consul key/value environment variables service
Typed retrieval of environment variables
EnvConsol object implements a simple ReadOnly/Immutable dict
Implemented using supported Python's Consul consulate
https://github.com/gmr/consulate

Install

shell pip install envconsul

Example Usage

Initialization

```python import envconsul

where service name is 'web00.django.test'

ENV_CONSUL = envconsul.EnvConsul('web00.django.test')

Or if using remote Consul instance

ENV_CONSUL = envconsul.EnvConsul( service_name='web00.django.test', host="localhost", port=8500, ) ```

Retrieval of Environment Variables

Example Django settings file

Full example here Django settings file here

Bool type

shell curl -X PUT -d 'True' http://localhost:8500/v1/kv/web00.django.test/debug

python DEBUG = ENV_CONSUL.get_bool('/debug', True)

Return list type

shell curl -X PUT -d "example.com, example.com." http://localhost:8500/v1/kv/web00.django.test/allowed_hosts

python ALLOWED_HOSTS = [] ALLOWED_HOSTS += ENV_CONSUL.get_list('/allowed_hosts', [])

Return tuple type

shell curl -X PUT -d 'django.contrib.admin, env' http://localhost:8500/v1/kv/web00.django.test/installed_apps

python INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', ) INSTALLED_APPS += ENV_CONSUL.get_tuple('/installed_apps', ['django.contrib.admin',])

Nested path example

shell curl -X PUT -d 'django.db.backends.sqlite3' http://localhost:8500/v1/kv/web00.django.test/databases/default/engine curl -X PUT -d 'db.sqlite3' http://localhost:8500/v1/kv/web00.django.test/databases/default/name

python DATABASES = { 'default': { 'ENGINE': ENV_CONSUL.get_str('/databases/default/engine'), 'NAME': os.path.join(BASE_DIR, ENV_CONSUL.get_str('/databases/default/name', 'db.sqlite3')), } }

Simple no-default, no type retrieval; not recommend

python REDIS_HOST = ENV_CONSUL.get('/redis_host')

Issues

Bump wheel from 0.24.0 to 0.38.1

opened on 2022-12-26 19:48:07 by dependabot[bot]

Bumps wheel from 0.24.0 to 0.38.1.

Changelog

Sourced from wheel's changelog.

Release Notes

UNRELEASED

Updated vendored packaging to 22.0

0.38.4 (2022-11-09)

Fixed PKG-INFO conversion in bdist_wheel mangling UTF-8 header values in METADATA (PR by Anderson Bravalheri)

0.38.3 (2022-11-08)

Fixed install failure when used with --no-binary, reported on Ubuntu 20.04, by removing setup_requires from setup.cfg

0.38.2 (2022-11-05)

Fixed regression introduced in v0.38.1 which broke parsing of wheel file names with multiple platform tags

0.38.1 (2022-11-04)

Removed install dependency on setuptools

The future-proof fix in 0.36.0 for converting PyPy's SOABI into a abi tag was faulty. Fixed so that future changes in the SOABI will not change the tag.

0.38.0 (2022-10-21)

Dropped support for Python < 3.7

Updated vendored packaging to 21.3

Replaced all uses of distutils with setuptools

The handling of license_files (including glob patterns and default values) is now delegated to setuptools>=57.0.0 (#466). The package dependencies were updated to reflect this change.

Fixed potential DoS attack via the WHEEL_INFO_RE regular expression

Fixed ValueError: ZIP does not support timestamps before 1980 when using SOURCE_DATE_EPOCH=0 or when on-disk timestamps are earlier than 1980-01-01. Such timestamps are now changed to the minimum value before packaging.

0.37.1 (2021-12-22)

Fixed wheel pack duplicating the WHEEL contents when the build number has changed (#415)

Fixed parsing of file names containing commas in RECORD (PR by Hood Chatham)

0.37.0 (2021-08-09)

Added official Python 3.10 support

Updated vendored packaging library to v20.9
