additionalAlertManagerConfigs

object

AdditionalAlertManagerConfigs allows specifying a key of a Secret containing additional Prometheus AlertManager configurations. AlertManager 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/#alertmanager_config. As AlertManager 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 AlertManager configs are going to break Prometheus after the upgrade.

additionalAlertRelabelConfigs

object

AdditionalAlertRelabelConfigs allows specifying a key of a Secret containing additional Prometheus alert relabel configurations. Alert relabel configurations specified are appended to the configurations generated by the Prometheus Operator. Alert relabel configurations specified must have the form as specified in the official Prometheus documentation: https://prometheus.io/docs/prometheus/latest/configuration/configuration/#alert_relabel_configs. As alert relabel 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 alert relabel configs are going to break Prometheus after the upgrade.

additionalArgs

array

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.

additionalArgs[]

object

Argument as part of the AdditionalArgs list.

additionalScrapeConfigs

object

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.

containers

array

Containers allows injecting additional containers or modifying operator generated containers. This can be used to allow adding an authentication proxy to a Prometheus pod 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 current container names are: prometheus, config-reloader, and 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.

containers[]

object

disableCompaction

boolean

Disable prometheus compaction.

enableAdminAPI

boolean

Enable access to prometheus web admin API. Defaults to the value of false. WARNING: Enabling the admin APIs enables mutating endpoints, to delete data, shutdown Prometheus, and more.

For more information see https://prometheus.io/docs/prometheus/latest/querying/api/#tsdb-admin-apis

enableFeatures

array (string)

Enable access to Prometheus disabled features. By default, no features are enabled. Enabling disabled features 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/disabled_features/

enableRemoteWriteReceiver

boolean

Enable Prometheus to be used as a receiver for the Prometheus remote write protocol. Defaults to the value of false. 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 Only valid in Prometheus versions 2.33.0 and newer.

enforcedBodySizeLimit

Per-scrape limit on number of labels that will be accepted for a sample. If more than this number of labels are present post metric-relabeling, the entire scrape will be treated as failed. 0 means no limit. Only valid in Prometheus versions 2.27.0 and newer.

enforcedLabelNameLengthLimit

integer

Per-scrape limit on length of labels name that will be accepted for a sample. If a label name is longer than this number post metric-relabeling, the entire scrape will be treated as failed. 0 means no limit. Only valid in Prometheus versions 2.27.0 and newer.

enforcedLabelValueLengthLimit

integer

Per-scrape limit on length of labels value that will be accepted for a sample. If a label value is longer than this number post metric-relabeling, the entire scrape will be treated as failed. 0 means no limit. Only valid in Prometheus versions 2.27.0 and newer.

enforcedNamespaceLabel

EnforcedNamespaceLabel If set, a label will be added to 1. all user-metrics (created by ServiceMonitor, PodMonitor and Probe objects) and 2. in all PrometheusRule objects (except the ones excluded in prometheusRulesExcludedFromEnforce) to * alerting & recording rules and * the metrics used in their expressions (expr). Label name is this field’s value. Label value is the namespace of the created object (mentioned above).

enforcedSampleLimit

integer

EnforcedSampleLimit defines global limit on number of scraped samples that will be accepted. This overrides any SampleLimit set per ServiceMonitor or/and PodMonitor. It is meant to be used by admins to enforce the SampleLimit to keep overall number of samples/series under the desired limit. Note that if SampleLimit is lower that value will be taken instead.

enforcedTargetLimit

integer

EnforcedTargetLimit defines a global limit on the number of scraped targets. This overrides any TargetLimit set per ServiceMonitor or/and PodMonitor. It is meant to be used by admins to enforce the TargetLimit to keep the overall number of targets under the desired limit. Note that if TargetLimit is lower, that value will be taken instead, except if either value is zero, in which case the non-zero value will be used. If both values are zero, no limit is enforced.

nodeSelector

object (string)

Define which Nodes the Pods are scheduled on.

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 stdout location such as /dev/stdout to log query information to the default Prometheus log stream. This is only available in versions of Prometheus >= 2.16.0. For more details, see the Prometheus docs (https://prometheus.io/docs/guides/query-log/)

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.

sha

string

SHA of Prometheus container image to be deployed. Defaults to the value of version. Similar to a tag, but the SHA explicitly deploys an immutable container image. Version and Tag are ignored if SHA is set. Deprecated: use 'image' instead. The image digest can be specified as part of the image URL.

shards

integer

An empty selector ({}) matches all namespaces.

namespaces

array (string)

namespaces specifies a static list of namespace names that the term applies to. The term is applied to the union of the namespaces listed in this field and the ones selected by namespaceSelector. null or empty namespaces list and null namespaceSelector means "this pod’s namespace".

topologyKey

string

This pod should be co-located (affinity) or not co-located (anti-affinity) with the pods matching the labelSelector in the specified namespaces, where co-located is defined as running on a node whose value of the label with key topologyKey matches that of any node on which any of the selected pods is running. Empty topologyKey is not allowed.

matchExpressions

array

matchExpressions is a list of label selector requirements. The requirements are ANDed.

matchExpressions[]

object

A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values.

matchLabels

object (string)

matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed.

key

string

key is the label key that the selector applies to.

operator

string

operator represents a key’s relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.

values

array (string)

values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch.

preferredDuringSchedulingIgnoredDuringExecution

array

The scheduler will prefer to schedule pods to nodes that satisfy the anti-affinity expressions specified by this field, but it may choose a node that violates one or more of the expressions. The node that is most preferred is the one with the greatest sum of weights, i.e. for each node that meets all of the scheduling requirements (resource request, requiredDuringScheduling anti-affinity expressions, etc.), compute a sum by iterating through the elements of this field and adding "weight" to the sum if the node has pods which matches the corresponding podAffinityTerm; the node(s) with the highest sum are the most preferred.

preferredDuringSchedulingIgnoredDuringExecution[]

object

The weights of all of the matched WeightedPodAffinityTerm fields are added per-node to find the most preferred node(s)

requiredDuringSchedulingIgnoredDuringExecution

array

If the anti-affinity requirements specified by this field are not met at scheduling time, the pod will not be scheduled onto the node. If the anti-affinity requirements specified by this field cease to be met at some point during pod execution (e.g. due to a pod label update), the system may or may not try to eventually evict the pod from its node. When there are multiple elements, the lists of nodes corresponding to each podAffinityTerm are intersected, i.e. all terms must be satisfied.

requiredDuringSchedulingIgnoredDuringExecution[]

object

Defines a set of pods (namely those matching the labelSelector relative to the given namespace(s)) that this pod should be co-located (affinity) or not co-located (anti-affinity) with, where co-located is defined as running on a node whose value of the label with key <topologyKey> matches that of any node on which a pod of the set of pods is running

podAffinityTerm

object

Required. A pod affinity term, associated with the corresponding weight.

weight

integer

weight associated with matching the corresponding podAffinityTerm, in the range 1-100.

labelSelector

object

A label query over a set of resources, in this case pods.

namespaceSelector

object

A label query over the set of namespaces that the term applies to. The term is applied to the union of the namespaces selected by this field and the ones listed in the namespaces field. null selector and null or empty namespaces list means "this pod’s namespace". An empty selector ({}) matches all namespaces.

namespaces

array (string)

namespaces specifies a static list of namespace names that the term applies to. The term is applied to the union of the namespaces listed in this field and the ones selected by namespaceSelector. null or empty namespaces list and null namespaceSelector means "this pod’s namespace".
