Helm: Passing array values through --set

Update for Helm 2.5.0

As of Helm 2.5.0, it is possible to access list items using an array index syntax.

For example, --set servers[0].port=80 becomes:

servers:
  - port: 80

If you need to pass array values you can use curly braces (unix shell require quotes):

--set test={x,y,z}
--set "test={x,y,z}"

Result YAML:

test:
  - x
  - y
  - z

EDITED : added double-quotes for unix shell like bash
