||
| ## Installation | ||
|
|
||
| With de-installation of the origin Rancher Monitoring and keept resources | ||
| A fork of the official [rancher cluster monitoring](https://github.com/rancher/charts/tree/dev-v2.9/charts/rancher-monitoring) with more up-to-date prometheus-operator CRDs and features and [prometheus-auth](https://github.com/caas-team/prometheus-auth) to enable multi-tenancy for the proemtheus metrics. | ||
|
|
||
| ```bash | ||
| helm -n cattle-monitoring-system delete rancher-monitoring | ||
| kubectl -n cattle-monitoring-system delete secret alertmanager-rancher-monitoring-alertmanager | ||
| ``` | ||
| ## Maintainers | ||
|
|
||
| Deleting of rancher-monitoring-crd would delete also all corresponding Custom Resources. We delete only the Helm release secrets and keep CRDs into the cluster | ||

|
|
||
| ```bash | ||
| kubectl -n cattle-monitoring-system get secrets -o name --no-headers | grep sh.helm.release.v1.rancher-monitoring-crd | xargs kubectl -n cattle-monitoring-system delete $1 | ||
| ``` | ||
| ## Source Code | ||
|
|
||
| Nevertheless we need to upgrade CRDs manually because there is no logic to do this in Helm: | ||
| * <https://github.com/caas-team/caas-cluster-monitoring> | ||
| * <https://github.com/prometheus-community/helm-charts> | ||
|
|
||
| ```bash | ||
| cd charts | ||
| tar xvfz kube-prometheus-stack-51.0.3.tgz | ||
| cd kube-prometheus-stack/charts/crds | ||
| kubectl apply -f crds/ --server-side --force-conflicts | ||
| ``` | ||
| ## Installation | ||
|
|
||
| To decouple CRDs from this chart (you may have installed CRDs from another chart or logic), feature is disabled: | ||
| If you're comming from an existing rancher-monitoring installation: | ||
|
|
||
| ```yaml | ||
| kube-prometheus-stack: | ||
| crds: | ||
| enabled: false | ||
| ``` | ||
| - you must first update the prometheus-operator CRDs separately. This chart only includes the kube-prometheus-stack *without* the CRDs. | ||
| - you should additionally uninstall the rancher-monitoring chart before installing this one. | ||
| - do not delete the rancher-monitoring-crds chart, as this will delete all custom resources already created (or back them up first and recreate them). | ||
|
|
||
| Upgrade to the kube-prometheus-stack: | ||
| To install run the following command: | ||
|
|
||
| ```bash | ||
| helm -n cattle-monitoring-system upgrade -i rancher-monitoring . | ||
| ``` | ||

| ## Compatibility matrix | ||
|
|
||
| The following table shows the compatibility between the CaaS Cluster Monitoring chart and the CaaS Project Monitoring versions: | ||
|
|
||
| | CaaS Cluster Monitoring | compatible with CaaS Project Monitoring | deployed kube-prometheus-stack | | ||
| | ----------------------- | --------------------------------------- | ------------------------------ | | ||
| | < 0.0.6 | < 1.0.0 | 51.0.3 | | ||
| | 0.0.6 < x < 1.0.0 | 1.0.0 <= y < 1.4.0 | 58.4.0 | | ||
|
|
||
| where `x` is the CaaS Cluster Monitoring Version and `y` is the CaaS Project Monitoring Version. | ||
|
|
||
| ## Configuration | ||
|
|
||
| The installation can be configured using the various parameters defined in the `values.yaml` file. The following tables list the configurable parameters of the CaaS Cluster Monitoring chart and their default values. | ||
