Bitnami package for Prometheus Operator

Prometheus Operator provides easy monitoring definitions for Kubernetes services and deployment and management of Prometheus instances.

Overview of Prometheus Operator

Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.

TL;DR

helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/kube-prometheus

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository.

Introduction

This chart bootstraps Prometheus Operator on Kubernetes using the Helm package manager.

In the default configuration the chart deploys the following components on the Kubernetes cluster:

:warning: IMPORTANT

Only one instance of the Prometheus Operator component should be running in the cluster. If you wish to deploy this chart to manage multiple instances of Prometheus in your Kubernetes cluster, you have to disable the installation of the Prometheus Operator component using the operator.enabled=false chart installation argument.

Bitnami charts can be used with Kubeapps for deployment and management of Helm Charts in clusters.

Prerequisites

  • Kubernetes 1.23+
  • Helm 3.8.0+

Installing the Chart

To install the chart with the release name my-release:

helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/kube-prometheus

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts.

The command deploys kube-prometheus on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Configuration and installation details

Resource requests and limits

Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the resources value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.

To make this process easier, the chart contains the resourcesPreset values, which automatically sets the resources section according to different presets. Check these presets in the bitnami/common chart. However, in production workloads using resourcePreset is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the official Kubernetes documentation.

Rolling vs Immutable tags

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

Additional scrape configurations

The following values have been deprecated. See Upgrading below.

prometheus.additionalScrapeConfigsExternal.enabled
prometheus.additionalScrapeConfigsExternal.name
prometheus.additionalScrapeConfigsExternal.key

It is possible to inject externally managed scrape configurations via a Secret by setting prometheus.additionalScrapeConfigs.enabled to true and prometheus.additionalScrapeConfigs.type to external. The secret must exist in the same namespace as the chart deployment. Set the secret name using the parameter prometheus.additionalScrapeConfigs.external.name, and the key containing the additional scrape configuration using the prometheus.additionalScrapeConfigs.external.key.

prometheus.additionalScrapeConfigs.enabled=true
prometheus.additionalScrapeConfigs.type=external
prometheus.additionalScrapeConfigs.external.name=kube-prometheus-prometheus-scrape-config
prometheus.additionalScrapeConfigs.external.key=additional-scrape-configs.yaml

It is also possible to define scrape configurations to be managed by the Helm chart by setting prometheus.additionalScrapeConfigs.enabled to true and prometheus.additionalScrapeConfigs.type to internal. You can then use prometheus.additionalScrapeConfigs.internal.jobList to define a list of additional scrape jobs for Prometheus.

prometheus.additionalScrapeConfigs.enabled=true
prometheus.additionalScrapeConfigs.type=internal
prometheus.additionalScrapeConfigs.internal.jobList=
      - job_name: 'opentelemetry-collector'
        # metrics_path defaults to '/metrics'
        # scheme defaults to 'http'.
        static_configs:
          - targets: ['opentelemetry-collector:8889']

For more information, see the additional scrape configuration documentation.

Additional alert relabel configurations

It is possible to inject externally managed Prometheus alert relabel configurations via a Secret by setting prometheus.additionalAlertRelabelConfigsExternal.enabled to true. The secret must exist in the same namespace as the chart deployment.

Set the secret name using the parameter prometheus.additionalAlertRelabelConfigsExternal.name, and the key containing the additional alert relabel configuration using the prometheus.additionalAlertRelabelConfigsExternal.key. For instance, if you created a secret named kube-prometheus-prometheus-alert-relabel-config and it contains a file named additional-alert-relabel-configs.yaml, use the parameters below:

prometheus.additionalAlertRelabelConfigsExternal.enabled=true
prometheus.additionalAlertRelabelConfigsExternal.name=kube-prometheus-prometheus-alert-relabel-config
prometheus.additionalAlertRelabelConfigsExternal.key=additional-alert-relabel-configs.yaml

Set Pod affinity

This chart allows setting custom Pod affinity using the XXX.affinity parameter(s). Find more information about Pod’s affinity in the Kubernetes documentation.

As an alternative, use one of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the bitnami/common chart. To do so, set the XXX.podAffinityPreset, XXX.podAntiAffinityPreset, or XXX.nodeAffinityPreset parameters.

RBAC parameters

Name Description Value
rbac.create Whether to create and use RBAC resources or not true
rbac.pspEnabled Whether to create a PodSecurityPolicy and bound it with RBAC. WARNING: PodSecurityPolicy is deprecated in Kubernetes v1.21 or later, unavailable in v1.25 or later true

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

helm install my-release \
  --set operator.logLevel=debug \
  --set prometheus.replicaCount=5 \
    oci://REGISTRY_NAME/REPOSITORY_NAME/kube-prometheus

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts.

The above command sets the Prometheus Operator logLevel to debug. Additionally it sets the prometheus.replicaCount to 5.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

helm install my-release -f values.yaml oci://REGISTRY_NAME/REPOSITORY_NAME/kube-prometheus

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts. Tip: You can use the default values.yaml

Troubleshooting

Find more information about how to deal with common errors related to Bitnami’s Helm charts in this troubleshooting guide.

While upgrading a chart, please note that there are certain limitations to upgrading CRDs. This limitation requires manual installation of the CRDs. Refer to the following Helm documentation.

Upgrading

helm upgrade my-release oci://REGISTRY_NAME/REPOSITORY_NAME/kube-prometheus

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts.

To 9.0.0

This major bump changes the following security defaults:

  • runAsGroup is changed from 0 to 1001
  • readOnlyRootFilesystem is set to true
  • resourcesPreset is changed from none to the minimum size working in our test suites (NOTE: resourcesPreset is not meant for production usage, but resources adapted to your use case).
  • global.compatibility.openshift.adaptSecurityContext is changed from disabled to auto.

This could potentially break any customization or init scripts used in your deployment. If this is the case, change the default values to the previous ones.

To 6.0.0

This major update changes the securityContext interface in the values.yaml file.

Please note if you have changes in the securityContext fields those need to be migrated to podSecurityContext.

# ...
- securityContext:
+ podSecurityContext:
# ...

Other than that a new securityContext interface for containers got introduced containerSecurityContext. It’s default is enabled so if you do not need it you need to opt out of it.

If you use Strategic Merge Patch for any of the Alertmanager or Prometheus kinds you need to actively disable all of those things below. For the resource you want to use Strategic Merge Patch for.

<resource>:
  containerSecurityContext:
    enabled: false
  livenessProbe:
    enabled: false
  readinessProbe:
    enabled: false

To 5.0.0

This major updates the kube-state-metrics subchart to it newest major, 2.0.0, which contains name changes to a few of its values. For more information on this subchart’s major, please refer to kube-state-metrics upgrade notes.

To 4.4.0

This version replaced the old configReloaderCpu and configReloaderMemory variables in favor of the new configReloaderResources map to define the requests and limits for the config-reloader sidecards. Users who made use of the old variables will need to migrate to the new ones.

To 4.0.0

This version standardizes the way of defining Ingress rules. When configuring a single hostname for the Prometheus Ingress rule, set the prometheus.ingress.hostname value. When defining more than one, set the prometheus.ingress.extraHosts array. When configuring a single hostname for the Alertmanager Ingress rule, set the alertmanager.ingress.hostname value. When defining more than one, set the alertmanager.ingress.extraHosts array.

Apart from this case, no issues are expected to appear when upgrading.

To 3.4.0

Some parameters disappeared in favor of new ones:

  • prometheus.additionalScrapeConfigsExternal.enabled -> deprecated in favor of prometheus.additionalScrapeConfigs.enabled and prometheus.additionalScrapeConfigs.type.
  • prometheus.additionalScrapeConfigsExternal.name -> deprecated in favor of prometheus.additionalScrapeConfigs.external.name.
  • prometheus.additionalScrapeConfigsExternal.key -> deprecated in favor of prometheus.additionalScrapeConfigs.external.key.

Adapt you parameters accordingly if you are external scrape configs.

To 3.1.0

Some parameters disappeared in favor of new ones:

  • *.podAffinity -> deprecated in favor of *.podAffinityPreset.
  • *.podAntiAffinity -> deprecated in favor of *.podAntiAffinityPreset.
  • *.nodeAffinity -> deprecated in favor of *.nodeAffinityPreset.type, *.nodeAffinityPreset.key and *.nodeAffinityPreset.values.

Adapt parameters accordingly if you are setting custom affinity.

To 3.0.0

On November 13, 2020, Helm v2 support formally ended. This major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.

To 2.1.0

Note: ignore these instructions if you did not enabled the Thanos sidecar on Prometheus pods.

The Thanos sidecar svc is transformed into a headless service by default so Thanos can discover every available sidecar. You can undo this change by setting the prometheus.thanos.service.clusterIP parameter to an empty string "".

To upgrade from version 2.0.0, previously remove the Thanos sidecar svc to avoid issues with immutable fields:

kubectl delete svc my-relase-kube-prometheus-prometheus-thanos
helm upgrade my-release --set prometheus.thanos.create=true oci://REGISTRY_NAME/REPOSITORY_NAME/kube-prometheus

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts.

To 2.0.0

  • CRDs were updated to the latest prometheus-operator v0.4.1 release artifacts
    • The apiVersion of CRDs was updated from apiextensions.k8s.io/v1beta1 to apiextensions.k8s.io/v1
    • Kubernetes 1.16 is required

To 1.0.0

  • The chart was renamed to kube-prometheus to be more accurate with the actual capabilities of the chart: it does not just deploy the Prometheus operator, it deploys an entire cluster monitoring stack, that includes other components (e.g. NodeExporter or Kube State metrics). Find more information about the reasons behind this decision at #3490.
  • New CRDs were added and some existing ones were updated.
  • This version also introduces bitnami/common, a library chart as a dependency. More documentation about this new utility could be found here. Please, make sure that you have updated the chart dependencies before executing any upgrade.

Note: There is no backwards compatibility due to the above mentioned changes. It’s necessary to install a new release of the chart, and migrate the existing TSDB data to the new Prometheus instances.
