To add support for object gateways this change adds the radosgw-user interface. The focal bundle has one rados gateway application as more than that is not supported on Octopus. The hersute bundle has two rados gateway applications but does not contain the lma applications as telegraf is not supported on hersute.

Overview
The ceph-dashboard configures the [Ceph Dashboard][ceph-dashboard-upstream]. The charm is intended to be used in conjunction with the ceph-mon charm.
Usage
Configuration
See file config.yaml for the full list of options, along with their
descriptions and default values.
Deployment
We are assuming a pre-existing Ceph cluster.
Deploy the ceph-dashboard as a subordinate to the ceph-mon charm.
juju deploy ceph-dashboard
juju relate ceph-dashboard ceph-mon
Embedded Grafana Dashboards
To enable the embedded grafana dashboards within the Ceph dashboard some additional relations are needed.
juju relate ceph-dashboard:grafana-dashboard grafana:dashboards
juju relate ceph-dashboard:prometheus prometheus:website
juju relate ceph-mon:prometheus prometheus:target
juju relate ceph-osd:juju-info telegraf:juju-info
juju relate ceph-mon:juju-info telegraf:juju-info
Grafana, Telegraf and Prometheus should be related in the standard way
juju relate grafana:grafana-source prometheus:grafana-source
juju relate telegraf:prometheus-client prometheus:target
juju relate telegraf:dashboards grafana:dashboards
Grafana must be using https so either supply a certificates and key via the ssl_* charm config options or add a vault relation.
juju deploy grafana:certificates vault:certificates
Grafana should be set with the following charm options:
juju config grafana anonymous=True
juju config grafana allow_embedding=True
juju config grafana install_plugins="https://storage.googleapis.com/plugins-community/vonage-status-panel/release/1.0.11/vonage-status-panel-1.0.11.zip,https://storage.googleapis.com/plugins-community/grafana-piechart-panel/release/1.6.2/grafana-piechart-panel-1.6.2.zip"
Telegraf should be set with the following charm options:
juju config telegraf hostname="{host}"
NOTE: That is "{host}" verbatim, nothing needs to be substituted.
Currently the dashboard cannot autodect the api endpoint of the grafana service, so the end of the deployment run the following:
juju config ceph-dashboard grafana-api-url="https://<IP of grafana unit>:3000"
Enabling Prometheus Alerting
To enable Prometheus alerting, add the following relations:
juju relate ceph-dashboard:prometheus prometheus:website
juju relate ceph-mon:prometheus prometheus:target
juju relate ceph-dashboard:alertmanager-service prometheus-alertmanager:alertmanager-service
juju relate prometheus:alertmanager-service prometheus-alertmanager:alertmanager-service
Object Gateway
To enable object gateway management add the following relation:
juju relate ceph-dashboard:radosgw-dashboard ceph-radosgw:radosgw-user
NOTE: On Octopus or earlier the dashboard can only be related to one ceph-radosgw application.
