Is it possible to customize the config from the command line?

It would be nice if I could do something like this:

config:
  target: "..."
  phases:
    - duration: {{process.env.MY_DURATION}}
      arrivalRate: {{process.env.MY_ARRIVAL_RATE}}

So that I don’t have to change the yaml contents to produce different test runs.

Is there any way of doing that?

No, not at the moment. I can think of a way to allow for arbitrary values to be overridden on the command line with something like:

artillery run --overrides '{"config": {"phases": [{"duration": 10, "arrivalRate": 10"}]}}' myscript.yaml

Thoughts? Would that work for what you are trying to do?

There will be a new release of Artillery later today with the change (#207 as well).
