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
curl -X PUT -d 'db.sqlite3' \
http://localhost:8500/v1/kv/web00.django.test/databases/default/nameEnvConsul can fetch and be queried like so
import envconsul
ENV_CONSUL = envconsul.EnvConsul('web00.django.test')
DATABASE_NAME = ENV_CONSUL.get_str('/databases/default/name')- 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
pip install envconsulimport 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,
