S3 Bucket is Hard Coded

[brockoffdev]

Hi :)

I'm going to try and open a PR for this, but right now the S3 bucket is hard coded to what appears to be an operable dev bucket? Our team would love to use this bundle, but it's a no go so long as that remains. We should be able to easily add vars to the config for AWS Access and Secret keys correct?

Thanks!

Hey @brockoffdev,
This bug looks like it would be pretty easy to fix if you want to give it a shot. To extend this a little bit, you'll also want the region to be configurable as well, so here's the changes to make:

1. Add configuration options to config.yml for GRAFANA_BUCKET and GRAFANA_REGION
2. Change the code in lib/grafana/client.rb to use the environment variables instead of the hard coded values
