Expected behavior

I expected to maintain a running process of consul-template

Actual behavior

What actually happened? It returned child process died with exit code 0.

Steps to reproduce

  1. Create a config.development.hcl with it's contents.
  2. create a config file called config-development.tpl with the contents.
  3. Run the command provided.

Instead of exec, using command solved the issue. But how to provide CONSUL_TOKEN in the hcl file?
