AdditionalAlertManagerConfigs specifies a key of a Secret containing additional Prometheus Alertmanager configurations. The Alertmanager configurations are appended to the configuration generated by the Prometheus Operator. They must be formatted according to the official Prometheus documentation: https://prometheus.io/docs/prometheus/latest/configuration/configuration/#alertmanager_config The user is responsible for making sure that the configurations are valid Note that using this feature may expose the possibility to break upgrades of Prometheus. It is advised to review Prometheus release notes to ensure that no incompatible AlertManager configs are going to break Prometheus after the upgrade.

AdditionalAlertRelabelConfigs specifies a key of a Secret containing additional Prometheus alert relabel configurations. The alert relabel configurations are appended to the configuration generated by the Prometheus Operator. They must be formatted according to the official Prometheus documentation: https://prometheus.io/docs/prometheus/latest/configuration/configuration/#alert_relabel_configs The user is responsible for making sure that the configurations are valid Note that using this feature may expose the possibility to break upgrades of Prometheus. It is advised to review Prometheus release notes to ensure that no incompatible alert relabel configs are going to break Prometheus after the upgrade.

AdditionalArgs allows setting additional arguments for the 'prometheus' container. It is intended for e.g. activating hidden flags which are not supported by the dedicated configuration options yet. The arguments are passed as-is to the Prometheus container which may cause issues if they are invalid or not supported by the given Prometheus version. In case of an argument conflict (e.g. an argument which is already set by the operator itself) or when providing an invalid argument, the reconciliation will fail and an error will be logged.

AdditionalScrapeConfigs allows specifying a key of a Secret containing additional Prometheus scrape configurations. Scrape configurations specified are appended to the configurations generated by the Prometheus Operator. Job configurations specified must have the form as specified in the official Prometheus documentation: https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config. As scrape configs are appended, the user is responsible to make sure it is valid. Note that using this feature may expose the possibility to break upgrades of Prometheus. It is advised to review Prometheus release notes to ensure that no incompatible scrape configs are going to break Prometheus after the upgrade.

• x-kubernetes-map-type: "atomic"

Defines the Pods' affinity scheduling rules if specified.

Defines the settings related to Alertmanager.

AllowOverlappingBlocks enables vertical compaction and vertical query merge in Prometheus. Deprecated: this flag has no effect for Prometheus >= 2.39.0 where overlapping blocks are enabled by default.

APIServerConfig allows specifying a host and auth methods to access the Kuberntees API server. If null, Prometheus is assumed to run inside of the cluster: it will discover the API servers automatically and use the Pod's CA certificate and bearer token file at /var/run/secrets/kubernetes.io/serviceaccount/.

When true, ServiceMonitor, PodMonitor and Probe object are forbidden to reference arbitrary files on the file system of the 'prometheus' container. When a ServiceMonitor's endpoint specifies a `bearerTokenFile` value (e.g. '/var/run/secrets/kubernetes.io/serviceaccount/token'), a malicious target can get access to the Prometheus service account's token in the Prometheus' scrape request. Setting `spec.arbitraryFSAccessThroughSM` to 'true' would prevent the attack. Users should instead provide the credentials using the `spec.bearerTokenSecret` field.

Deprecated: use 'spec.image' instead.

BodySizeLimit defines per-scrape on response body size. Only valid in Prometheus versions 2.45.0 and newer.

• pattern: (^0|([0-9]*[.])?[0-9]+((K|M|G|T|E|P)i?)?B)$

ConfigMaps is a list of ConfigMaps in the same namespace as the Prometheus object, which shall be mounted into the Prometheus Pods. Each ConfigMap is added to the StatefulSet definition as a volume named `configmap-<configmap-name>`. The ConfigMaps are mounted into /etc/prometheus/configmaps/<configmap-name> in the 'prometheus' container.

Containers allows injecting additional containers or modifying operator generated containers. This can be used to allow adding an authentication proxy to the Pods or to change the behavior of an operator generated container. Containers described here modify an operator generated container if they share the same name and modifications are done via a strategic merge patch. The names of containers managed by the operator are: * `prometheus` * `config-reloader` * `thanos-sidecar` Overriding containers is entirely outside the scope of what the maintainers will support and by doing so, you accept that this behaviour may break at any time without notice.

When true, the Prometheus compaction is disabled.

Enables access to the Prometheus web admin API. WARNING: Enabling the admin APIs enables mutating endpoints, to delete data, shutdown Prometheus, and more. Enabling this should be done with care and the user is advised to add additional authentication authorization via a proxy to ensure only clients authorized to perform these actions can do so. For more information: https://prometheus.io/docs/prometheus/latest/querying/api/#tsdb-admin-apis

Enable access to Prometheus feature flags. By default, no features are enabled. Enabling features which are disabled by default is entirely outside the scope of what the maintainers will support and by doing so, you accept that this behaviour may break at any time without notice. For more information see https://prometheus.io/docs/prometheus/latest/feature_flags/

Enable Prometheus to be used as a receiver for the Prometheus remote write protocol. WARNING: This is not considered an efficient way of ingesting samples. Use it with caution for specific low-volume use cases. It is not suitable for replacing the ingestion via scraping and turning Prometheus into a push-based metrics collection system. For more information see https://prometheus.io/docs/prometheus/latest/querying/api/#remote-write-receiver It requires Prometheus >= v2.33.0.

When defined, enforcedBodySizeLimit specifies a global limit on the size of uncompressed response body that will be accepted by Prometheus. Targets responding with a body larger than this many bytes will cause the scrape to fail. It requires Prometheus >= v2.28.0.

• pattern: (^0|([0-9]*[.])?[0-9]+((K|M|G|T|E|P)i?)?B)$

When defined, enforcedKeepDroppedTargets specifies a global limit on the number of targets dropped by relabeling that will be kept in memory. The value overrides any `spec.keepDroppedTargets` set by ServiceMonitor, PodMonitor, Probe objects unless `spec.keepDroppedTargets` is greater than zero and less than `spec.enforcedKeepDroppedTargets`. It requires Prometheus >= v2.47.0.

• format: int64

When defined, enforcedLabelLimit specifies a global limit on the number of labels per sample. The value overrides any `spec.labelLimit` set by ServiceMonitor, PodMonitor, Probe objects unless `spec.labelLimit` is greater than zero and less than `spec.enforcedLabelLimit`. It requires Prometheus >= v2.27.0.

• format: int64

When defined, enforcedLabelNameLengthLimit specifies a global limit on the length of labels name per sample. The value overrides any `spec.labelNameLengthLimit` set by ServiceMonitor, PodMonitor, Probe objects unless `spec.labelNameLengthLimit` is greater than zero and less than `spec.enforcedLabelNameLengthLimit`. It requires Prometheus >= v2.27.0.

• format: int64

When not null, enforcedLabelValueLengthLimit defines a global limit on the length of labels value per sample. The value overrides any `spec.labelValueLengthLimit` set by ServiceMonitor, PodMonitor, Probe objects unless `spec.labelValueLengthLimit` is greater than zero and less than `spec.enforcedLabelValueLengthLimit`. It requires Prometheus >= v2.27.0.

• format: int64

When not empty, a label will be added to 1. All metrics scraped from `ServiceMonitor`, `PodMonitor`, `Probe` and `ScrapeConfig` objects. 2. All metrics generated from recording rules defined in `PrometheusRule` objects. 3. All alerts generated from alerting rules defined in `PrometheusRule` objects. 4. All vector selectors of PromQL expressions defined in `PrometheusRule` objects. The label will not added for objects referenced in `spec.excludedFromEnforcement`. The label's name is this field's value. The label's value is the namespace of the `ServiceMonitor`, `PodMonitor`, `Probe` or `PrometheusRule` object.

When defined, enforcedSampleLimit specifies a global limit on the number of scraped samples that will be accepted. This overrides any `spec.sampleLimit` set by ServiceMonitor, PodMonitor, Probe objects unless `spec.sampleLimit` is greater than zero and less than than `spec.enforcedSampleLimit`. It is meant to be used by admins to keep the overall number of samples/series under a desired limit.

• format: int64

When defined, enforcedTargetLimit specifies a global limit on the number of scraped targets. The value overrides any `spec.targetLimit` set by ServiceMonitor, PodMonitor, Probe objects unless `spec.targetLimit` is greater than zero and less than `spec.enforcedTargetLimit`. It is meant to be used by admins to to keep the overall number of targets under a desired limit.

List of references to PodMonitor, ServiceMonitor, Probe and PrometheusRule objects to be excluded from enforcing a namespace label of origin. It is only applicable if `spec.enforcedNamespaceLabel` set to true.

Exemplars related settings that are runtime reloadable. It requires to enable the `exemplar-storage` feature flag to be effective.

The labels to add to any time series or alerts when communicating with external systems (federation, remote storage, Alertmanager). Labels defined by `spec.replicaExternalLabelName` and `spec.prometheusExternalLabelName` take precedence over this list.

The external URL under which the Prometheus service is externally available. This is necessary to generate correct URLs (for instance if Prometheus is accessible behind an Ingress resource).

Optional list of hosts and IPs that will be injected into the Pod's hosts file if specified.

• x-kubernetes-list-map-keys: ["ip"]
• x-kubernetes-list-type: "map"

Use the host's network namespace if true. Make sure to understand the security implications if you want to enable it (https://kubernetes.io/docs/concepts/configuration/overview/). When hostNetwork is enabled, this will set the DNS policy to `ClusterFirstWithHostNet` automatically.

When true, `spec.namespaceSelector` from all PodMonitor, ServiceMonitor and Probe objects will be ignored. They will only discover targets within the namespace of the PodMonitor, ServiceMonitor and Probe object.

Container image name for Prometheus. If specified, it takes precedence over the `spec.baseImage`, `spec.tag` and `spec.sha` fields. Specifying `spec.version` is still necessary to ensure the Prometheus Operator knows which version of Prometheus is being configured. If neither `spec.image` nor `spec.baseImage` are defined, the operator will use the latest upstream version of Prometheus available at the time when the operator was released.

Image pull policy for the 'prometheus', 'init-config-reloader' and 'config-reloader' containers. See https://kubernetes.io/docs/concepts/containers/images/#image-pull-policy for more details.

• enum: ["","Always","Never","IfNotPresent"]

An optional list of references to Secrets in the same namespace to use for pulling images from registries. See http://kubernetes.io/docs/user-guide/images#specifying-imagepullsecrets-on-a-pod

InitContainers allows injecting initContainers to the Pod definition. Those can be used to e.g. fetch secrets for injection into the Prometheus configuration from external sources. Any errors during the execution of an initContainer will lead to a restart of the Pod. More info: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/ InitContainers described here modify an operator generated init containers if they share the same name and modifications are done via a strategic merge patch. The names of init container name managed by the operator are: * `init-config-reloader`. Overriding init containers is entirely outside the scope of what the maintainers will support and by doing so, you accept that this behaviour may break at any time without notice.

Per-scrape limit on the number of targets dropped by relabeling that will be kept in memory. 0 means no limit. It requires Prometheus >= v2.47.0.

• format: int64

Per-scrape limit on number of labels that will be accepted for a sample. Only valid in Prometheus versions 2.45.0 and newer.

• format: int64

Per-scrape limit on length of labels name that will be accepted for a sample. Only valid in Prometheus versions 2.45.0 and newer.

• enum: ["","debug","info","warn","error"]

Defines the maximum time that the `prometheus` container's startup probe will wait before being considered failed. The startup probe will return success after the WAL replay is complete. If set, the value should be greater than 60 (seconds). Otherwise it will be equal to 600 seconds (15 minutes).

• format: int32
• minimum: 60

Minimum number of seconds for which a newly created Pod should be ready without any of its container crashing for it to be considered available. Defaults to 0 (pod will be considered available as soon as it is ready) This is an alpha field from kubernetes 1.22 until 1.24 which requires enabling the StatefulSetMinReadySeconds feature gate.

• format: int32

Defines on which Nodes the Pods are scheduled.

When true, Prometheus resolves label conflicts by renaming the labels in the scraped data to "exported_<label value>" for all targets created from service and pod monitors. Otherwise the HonorLabels field of the service or pod monitor applies.

When true, Prometheus ignores the timestamps for all the targets created from service and pod monitors. Otherwise the HonorTimestamps field of the service or pod monitor applies.

When a Prometheus deployment is paused, no actions except for deletion will be performed on the underlying objects.

The field controls if and how PVCs are deleted during the lifecycle of a StatefulSet. The default behavior is all PVCs are retained. This is an alpha field from kubernetes 1.23 until 1.26 and a beta field from 1.26. It requires enabling the StatefulSetAutoDeletePVC feature gate.

PodMetadata configures labels and annotations which are propagated to the Prometheus pods. The following items are reserved and cannot be overridden: * "prometheus" label, set to the name of the Prometheus object. * "app.kubernetes.io/instance" label, set to the name of the Prometheus object. * "app.kubernetes.io/managed-by" label, set to "prometheus-operator". * "app.kubernetes.io/name" label, set to "prometheus". * "app.kubernetes.io/version" label, set to the Prometheus version. * "operator.prometheus.io/name" label, set to the name of the Prometheus object. * "operator.prometheus.io/shard" label, set to the shard number of the Prometheus object. * "kubectl.kubernetes.io/default-container" annotation, set to "prometheus".

Namespaces to match for PodMonitors discovery. An empty label selector matches all namespaces. A null label selector matches the current namespace only.

• x-kubernetes-map-type: "atomic"

*Experimental* PodMonitors to be selected for target discovery. An empty label selector matches all objects. A null label selector matches no objects. If `spec.serviceMonitorSelector`, `spec.podMonitorSelector`, `spec.probeSelector` and `spec.scrapeConfigSelector` are null, the Prometheus configuration is unmanaged. The Prometheus operator will ensure that the Prometheus configuration's Secret exists, but it is the responsibility of the user to provide the raw gzipped Prometheus configuration under the `prometheus.yaml.gz` key. This behavior is *deprecated* and will be removed in the next major version of the custom resource definition. It is recommended to use `spec.additionalScrapeConfigs` instead.

• x-kubernetes-map-type: "atomic"

PodTargetLabels are appended to the `spec.podTargetLabels` field of all PodMonitor and ServiceMonitor objects.

Port name used for the pods and governing service. Default: "web"

• x-kubernetes-map-type: "atomic"

Name of Prometheus external label used to denote the Prometheus instance name. The external label will _not_ be added when the field is set to the empty string (`""`). Default: "prometheus"

Defines the list of PrometheusRule objects to which the namespace label enforcement doesn't apply. This is only relevant when `spec.enforcedNamespaceLabel` is set to true. Deprecated: use `spec.excludedFromEnforcement` instead.

QuerySpec defines the configuration of the Promethus query service.

queryLogFile specifies where the file to which PromQL queries are logged. If the filename has an empty path, e.g. 'query.log', The Prometheus Pods will mount the file into an emptyDir volume at `/var/log/prometheus`. If a full path is provided, e.g. '/var/log/prometheus/query.log', you must mount a volume in the specified directory and it must be writable. This is because the prometheus container runs with a read-only root filesystem for security reasons. Alternatively, the location can be set to a standard I/O stream, e.g. `/dev/stdout`, to log query information to the default Prometheus log stream.

Defines the strategy used to reload the Prometheus configuration. If not specified, the configuration is reloaded using the /-/reload HTTP endpoint.

• enum: ["HTTP","ProcessSignal"]

Maximum number of bytes used by the Prometheus data.

• pattern: (^0|([0-9]*[.])?[0-9]+((K|M|G|T|E|P)i?)?B)$

The route prefix Prometheus registers HTTP handlers for. This is useful when using `spec.externalURL`, and a proxy is rewriting HTTP routes of a request, and the actual ExternalURL is still true, but the server serves requests under a different route prefix. For example for use with `kubectl proxy`.

Deprecated: use 'spec.image' instead. The image's digest can be specified as part of the image name.

EXPERIMENTAL: Number of shards to distribute targets onto. `spec.replicas` multiplied by `spec.shards` is the total number of Pods created. Note that scaling down shards will not reshard data onto remaining instances, it must be manually moved. Increasing shards will not reshard data either but it will continue to be available from the same instances. To query globally, use Thanos sidecar and Thanos querier or remote write data to a central location. Sharding is performed on the content of the `__address__` target meta-label for PodMonitors and ServiceMonitors and `__param_target__` for Probes. Default: 1
