This guide will help you monitor applications in other Namespaces. By default the RBAC rules are only enabled for the `Default` and `kube-system` Namespace during Install.
|
|
|
|
# Setup
|
|
|
|
You have to give the list of the Namespaces that you want to be able to monitor.
|
|
This is done in the variable `prometheus.roleSpecificNamespaces`. You usually set this in your `.jsonnet` file when building the manifests.
|
|
|
|
Example to create the needed `Role` and `RoleBinding` for the Namespace `foo` :
|
|
|
|
```
|
|
local kp =
|
|
(import 'kube-prometheus/main.libsonnet') +
|
|
{
|
|
values+:: {
|
|
common+: {
|
|
namespace: 'monitoring',
|
|
},
|
|
|
|
prometheus+:: {
|
|
namespaces: ["default", "kube-system", "monitoring", "foo"],
|
|
},
|
|
},
|
|
};
|
|
|
|
{ 'setup/0namespace-namespace': kp.kubePrometheus.namespace } +
|
|
{
|
|
['setup/prometheus-operator-' + name]: kp.prometheusOperator[name]
|
|
for name in std.filter((function(name) name != 'serviceMonitor' && name != 'prometheusRule'), std.objectFields(kp.prometheusOperator))
|
|
} +
|
|
// serviceMonitor and prometheusRule are separated so that they can be created after the CRDs are ready
|
|
{ 'prometheus-operator-serviceMonitor': kp.prometheusOperator.serviceMonitor } +
|
|
{ 'prometheus-operator-prometheusRule': kp.prometheusOperator.prometheusRule } +
|
|
{ 'kube-prometheus-prometheusRule': kp.kubePrometheus.prometheusRule } +
|
|
{ ['alertmanager-' + name]: kp.alertmanager[name] for name in std.objectFields(kp.alertmanager) } +
|
|
{ ['blackbox-exporter-' + name]: kp.blackboxExporter[name] for name in std.objectFields(kp.blackboxExporter) } +
|
|
{ ['grafana-' + name]: kp.grafana[name] for name in std.objectFields(kp.grafana) } +
|
|
{ ['kube-state-metrics-' + name]: kp.kubeStateMetrics[name] for name in std.objectFields(kp.kubeStateMetrics) } +
|
|
{ ['kubernetes-' + name]: kp.kubernetesControlPlane[name] for name in std.objectFields(kp.kubernetesControlPlane) }
|
|
{ ['node-exporter-' + name]: kp.nodeExporter[name] for name in std.objectFields(kp.nodeExporter) } +
|
|
{ ['prometheus-' + name]: kp.prometheus[name] for name in std.objectFields(kp.prometheus) } +
|
|
{ ['prometheus-adapter-' + name]: kp.prometheusAdapter[name] for name in std.objectFields(kp.prometheusAdapter) }
|
|
```
