Allow parameters to be created from file and/or command line #16

Closed pvdvreede closed 8 years ago

pvdvreede commented 8 years ago

It would be cool if I could specify a parameters file and also set some parameters on the command line eg. stackup mystack up -t template -p paramsfile -p buildnumber=1.

This way I could change something like the version or build number from the command line and keep all other items in the params file. Currently I need to use sed and a placeholder in the params file to change this.

@pvdvreede would you want parameters on the command-line to override those in the params file?

I think it might be confusing to overload -p, so would prefer a different option for command-line overrides. How about --override, or -o?

Yeah, I would think the cli parameters override the file parameters, so -o sounds good to me :+1:
