Thank @iamNoah1

When I get the chance I will try following your instructions and merge if I can successfully install it.

Also @idachev may want to take a look as he has a chart that works and was thinking of adding it too.

EDIT: just waking up, also remembered there is already an open PR: #2276

@danny-avila @idachev what do you suggest on how to proceed?

Is there a reason for not creating helm for both MongoDB and Redis?

[iamNoah1]

@bnsd55 I wanna to keep it as simple as possible. For dev reasons having mongodb and redis also included as chart could come in handy, but in my use case I would want to have them externalized.

@iamNoah1 okay, I tried to run it and got error:

[iamNoah1]

@bnsd55 have a look at this: #651

Seems you haven't configured it correctly.
