additionalAlertManagerConfigs

object

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

object

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

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.

apiserverConfig

object

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/.

arbitraryFSAccessThroughSMs

object

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.

boolean

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.

image

string

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.

If the operator is Gt or Lt, the values array must have a single element, which will be interpreted as an integer. This array is replaced during a strategic merge patch.

preferredDuringSchedulingIgnoredDuringExecution

array

The scheduler will prefer to schedule pods to nodes that satisfy the 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 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 affinity requirements specified by this field are not met at scheduling time, the pod will not be scheduled onto the node. If the 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. If it’s null, this PodAffinityTerm matches with no Pods.

matchLabelKeys

array (string)

MatchLabelKeys is a set of pod label keys to select which pods will be taken into consideration. The keys are used to lookup values from the incoming pod labels, those key-value labels are merged with LabelSelector as key in (value) to select the group of existing pods which pods will be taken into consideration for the incoming pod’s pod (anti) affinity. Keys that don’t exist in the incoming pod labels will be ignored. The default value is empty. The same key is forbidden to exist in both MatchLabelKeys and LabelSelector. Also, MatchLabelKeys cannot be set when LabelSelector isn’t set. This is an alpha field and requires enabling MatchLabelKeysInPodAffinity feature gate.

mismatchLabelKeys

array (string)

MismatchLabelKeys is a set of pod label keys to select which pods will be taken into consideration. The keys are used to lookup values from the incoming pod labels, those key-value labels are merged with LabelSelector as key notin (value) to select the group of existing pods which pods will be taken into consideration for the incoming pod’s pod (anti) affinity. Keys that don’t exist in the incoming pod labels will be ignored. The default value is empty. The same key is forbidden to exist in both MismatchLabelKeys and LabelSelector. Also, MismatchLabelKeys cannot be set when LabelSelector isn’t set. This is an alpha field and requires enabling MatchLabelKeysInPodAffinity feature gate.

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".

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
