django-environ-ppb 1.0.1

easy 12factor for django settings

django-environ

django-environ is the Python package that allows you to use Twelve-factor methodology to configure your Django application with environment variables.

This is the PPB extension of it adding _VAULT and _FILE support to environment variable name parsing to read the setting from (respectivelly) that vault key or that file.

This should probably be a fork of the package instead of keeping it as a separate package.. TODO.

Usage

Refer to testapp for a working example.

As in testapp settings, initialize environ:

import ppbenviron

ENV_VAR = ppbenviron.CustomEnv()
ENV_VAR.read_env(BASE_DIR / 'local.env')

ENV_VAR.setup_vault(
    'ENVTEST_VAULT_URL',
    'ENVTEST_VAULT_TOKEN',
    'ENVTEST_VAULT_MOUNT',
    'ENVTEST_VAULT_PATHS',
    default_url='http://vault.local',
    default_token='tok3n',
    default_mount='/secrets',
    default_paths='staging,production',
)

Define settings:

TEST_SETTING_STR = ENV_VAR('ENVTEST_STR', default='missed')
TEST_SETTING_LIST = ENV_VAR('ENVTEST_LIST', default=['missed'])

Create a testapp/local.env or define the environment variabls in the current shell:

ENVTEST_VAULT_TOKEN_FILE=/home/myuser/.vault-token
ENVTEST_VAULT_MOUNT=other_mount
ENVTEST_VAULT_PATHS=dev,prd

ENVTEST_STR_FILE=/path/to/file will load /path/to/file in TEST_SETTING_STR.

ENVTEST_STR_VAULT=somepath will load /other_mount/prd[somepath] in TEST_SETTING_STR if it exists otherwise fallback to /other_mount/qa[somepath]
