yml2env

Executes a command with environment variables taken from a YAML file.

yml2env <path-to-yaml-file> <command>

Why?

It's quite handy for using Concourse --load-vars-from files when running local tasks, like tests.

Example

Given a YAML file stored in ci/vars/local.yml:

---
cf_username: admin
cf_password: whevsmate

...running yml2env ci/vars/local.yml fly execute ci/tasks/system-tests.yml is equivalent to running

CF_USERNAME=admin CF_PASSWORD=whevsmate fly execute ci/tasks/system-tests.yml
