It's true it's in need of an update. More than welcome any pull requests. I'm expecting to do a 'refresh' when rancher 2.0 launches to incorporate some of the changes and make it a little more up-to-date.

Good news if it's still alive :)

I also need update grafana because only version 5 has the mysql datasource.

We have to fork this repo ?
https://github.com/Rucknar/community-catalog/tree/master/templates/Prometheus

No github repo with only your catalogue ?

That's just my personal fork of Ranchers Catalog. The code is in https://github.com/rancher/community-catalog

Fork off that to make any changes.

2 PR :
infinityworks/prom-conf#6
To upgrade configuration
rancher/community-catalog#748
For a new catalogue version.

Be careful, the second PR can't work before you accept first one..

Il also add an option to select a volume driver for rancher (local as default like today)

Merged prom-conf, built :20 as a version off it and pushed it up.

Merge ok : version 4.0.0 with
prometheus:v2.1.0
grafana:5.0.0
