The GrafanaClient wrapper takes care of this. +### Managing Dashboards + +The dashboard json needs to be put into the `dashboards/v[X]` directory and will be picked up from there. + +The operator does not modify/update existing dashboards, it only installs new/missing dashboards. This is because Grafana may change dashboards (users may change them or Grafana might migrate them during a version upgrade), and we don't want the operator to revert those changes. In order to still be able to install newer versions of dashboards, the dashboard folder in the Grafana UI is versioned ("General v[X]") with the version number corresponding to the directory name in `dashboards`. Hence to add new versions of dashboards you create a `v[X+1]` directory inside `dashboards` and put them there. + +The operator does not remove old dashboard versions; both old and current versions remain available to Grafana users. This may change in the future. + +The suggested dashboards to use are the "kubernetes-mixin" dashboards. There is a helper script `get-k8s-mixins-sh` which downloads and builds the latest dashboard version for you; once that's done you need to rebuild the operator image and roll it out. + ## Development
