xk6-dotenv

A k6 extension that loads env vars from a .env file.

This extension follow the convention for managing multiple environments (i.e. development, test, production). The actual environment name came from an env variable named K6_ENV. Setting this to false value disable the convention mentoined above and no .env file will be loaded automatically.

Hierarchy Priority	Filename	K6_ENV	Should I .gitignoreit?	Notes
1st (highest)	.env.development.local	development	Yes!	Local overrides of environment-specific settings.
1st	.env.test.local	test	Yes!	Local overrides of environment-specific settings.
1st	.env.production.local	production	Yes!	Local overrides of environment-specific settings.
2nd	.env.local	(any expect false)	Definitely.	Local overrides. This file is loaded for all environments except test.
3rd	.env.development	development	No.	Shared environment-specific settings
3rd	.env.test	test	No.	Shared environment-specific settings
3rd	.env.production	production	No.	Shared environment-specific settings
Last	.env	(any expect false)	Depends	The Original

Usage

The .env files are loaded automatically when starting k6. To use it, simply create the appropriate .env file (see table above) and set (optional) the K6_ENV environment variable.

For the most convenient use, create a file called .env.local and write the environment variables you want to set in it. One variable per line, in name=value form.

SOME_ENV_VAR=somevalue

If you want to be really fancy with your env file you can do comments and exports:

# I am a comment and that is OK
SOME_VAR=someval
FOO=BAR # comments at line end are OK too
export BAR=BAZ
