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. |
|
|

|
Define details regarding alerting. |
|
|
AllowOverlappingBlocks enables vertical compaction and vertical query merge in Prometheus. This is still experimental in Prometheus so it may change in any upcoming release. |
|
|
APIServerConfig allows specifying a host and auth methods to access apiserver. If left empty, Prometheus is assumed to run inside of the cluster and will discover API servers automatically and use the pod’s CA certificate and bearer token file at /var/run/secrets/kubernetes.io/serviceaccount/. |
|
|
ArbitraryFSAccessThroughSMs configures whether configuration based on a service monitor can access arbitrary files on the file system of the Prometheus container e.g. bearer token files. |
|
|
Base image to use for a Prometheus deployment. Deprecated: use 'image' instead |
|
|
ConfigMaps is a list of ConfigMaps in the same namespace as the Prometheus object, which shall be mounted into the Prometheus Pods. The ConfigMaps are mounted into /etc/prometheus/configmaps/<configmap-name>. |
|
|
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: |
|
|
A single application container that you want to run within a pod. |
|
|
Disable prometheus compaction. |
|
|
Enable access to prometheus web admin API. Defaults to the value of |
|
|
EnforcedNamespaceLabel enforces adding a namespace label of origin for each alert and metric that is user created. The label value will always be the namespace of the object that is being created. |
|
|
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. |
|
|
Interval between consecutive evaluations. |
|
|
The labels to add to any time series or alerts when communicating with external systems (federation, remote storage, Alertmanager). |
|
|
The external URL the Prometheus instances will be available under. This is necessary to generate correct URLs. This is necessary if Prometheus is not served from root of a DNS name. |

|
IgnoreNamespaceSelectors if set to true will ignore NamespaceSelector settings from the podmonitor and servicemonitor configs, and they will only discover endpoints within their current namespace. Defaults to false. |
|
|
Image if specified has precedence over baseImage, tag and sha combinations. Specifying the version is still necessary to ensure the Prometheus Operator knows what version of Prometheus is being configured. |

LocalObjectReference contains enough information to let you locate the referenced object inside the same namespace. |
|
|
InitContainers allows adding 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/ Using initContainers for any use case other then secret fetching 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. |
|
|
A single application container that you want to run within a pod. |
|
|
ListenLocal makes the Prometheus server listen on loopback, so that it does not bind against the Pod IP. |
|
|
Log format for Prometheus to be configured with. |
|
|
Log level for Prometheus to be configured with. |
|
|
Define which Nodes the Pods are scheduled on. |
|
|
OverrideHonorLabels if set to true overrides all user configured honor_labels. If HonorLabels is set in ServiceMonitor or PodMonitor to true, this overrides honor_labels to false. |
|
|
OverrideHonorTimestamps allows to globally enforce honoring timestamps in all scrape configs. |
|
|
When a Prometheus deployment is paused, no actions except for deletion will be performed on the underlying objects. |
|
|
PodMetadata configures Labels and Annotations which are propagated to the prometheus pods. |
|
|
Namespaces to be selected for PodMonitor discovery. If nil, only check own namespace. |
|
|

|
|
Experimental Namespaces to be selected for Probe discovery. If nil, only check own namespace. |
|
|
Experimental Probes to be selected for target discovery. |
|
|
Name of Prometheus external label used to denote Prometheus instance name. Defaults to the value of |
|
|
PrometheusRulesExcludedFromEnforce - list of prometheus rules to be excluded from enforcing of adding namespace labels. Works only if enforcedNamespaceLabel set to true. Make sure both ruleNamespace and ruleName are set for each pair |
|
|
PrometheusRuleExcludeConfig enables users to configure excluded PrometheusRule names and their namespaces to be ignored while enforcing namespace label for alerts and metrics. |
|
|
QuerySpec defines the query command line flags when starting Prometheus. |
|
|
QueryLogFile specifies the file to which PromQL queries are logged. Note that this location must be writable, and can be persisted using an attached volume. Alternatively, the location can be set to a stdout location such as |
|
|
If specified, the remote_read spec. This is an experimental feature, it may change in any upcoming release in a breaking way. |
|
|
RemoteReadSpec defines the remote_read configuration for prometheus. |
|
|
If specified, the remote_write spec. This is an experimental feature, it may change in any upcoming release in a breaking way. |
|
|
RemoteWriteSpec defines the remote_write configuration for prometheus. |
|
|
Name of Prometheus external label used to denote replica name. Defaults to the value of |
|
|
Number of instances to deploy for a Prometheus deployment. |
|
|
Define resources requests and limits for single Pods. |
|
|
Time duration Prometheus shall retain data for. Default is '24h', and must match the regular expression |
|
|
Maximum amount of disk space used by blocks. |
|
|
The route prefix Prometheus registers HTTP handlers for. This is useful, if using 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 |
|
|
Namespaces to be selected for PrometheusRules discovery. If unspecified, only the same namespace as the Prometheus object is in is used. |
|
|
A selector to select which PrometheusRules to mount for loading alerting/recording rules from. Until (excluding) Prometheus Operator v0.24.0 Prometheus Operator will migrate any legacy rule ConfigMaps to PrometheusRule custom resources selected by RuleSelector. Make sure it does not match any config maps that you do not want to be migrated. |
|
|
/--rules.*/ command-line arguments. |
|
|
Interval between consecutive scrapes. |
|
|
Number of seconds to wait for target to respond before erroring. |
|
|
Secrets is a list of Secrets in the same namespace as the Prometheus object, which shall be mounted into the Prometheus Pods. The Secrets are mounted into /etc/prometheus/secrets/<secret-name>. |
|
|

|
|
ServiceAccountName is the name of the ServiceAccount to use to run the Prometheus Pods. |
|
|
Namespaces to be selected for ServiceMonitor discovery. If nil, only check own namespace. |
|
|

|
|
Version of Prometheus to be deployed. |
|
|

|
|
VolumeMount describes a mounting of a Volume within a container. |
|
|
Volumes allows configuration of additional volumes on the output StatefulSet definition. Volumes specified will be appended to other volumes that are generated as a result of StorageSpec objects. |
|
|
Volume represents a named volume in a pod that may be accessed by any container in the pod. |
|
|
Enable compression of the write-ahead log using Snappy. This flag is only available in versions of Prometheus >= 2.11.0. |
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.

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. |

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 |
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.

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
, prometheus-config-reloader
, rules-configmap-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.

StartupProbe indicates that the Pod has successfully initialized. If specified, no other probes are executed until this completes successfully. If this probe fails, the Pod will be restarted, just as if the livenessProbe failed. This can be used to provide different probe parameters at the beginning of a Pod’s lifecycle, when it might take a long time to load data or warm a cache, than during steady-state operation. This cannot be updated. This is a beta feature enabled by the StartupProbe feature flag. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes |

Whether this container should allocate a buffer for stdin in the container runtime. If this is not set, reads from stdin in the container will always result in EOF. Default is false. |
|
|
Whether the container runtime should close the stdin channel after it has been opened by a single attach. When stdin is true the stdin stream will remain open across multiple attach sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the first client attaches to stdin, and then remains open and accepts data until the client disconnects, at which time stdin is closed and remains closed until the container is restarted. If this flag is false, a container processes that reads from stdin will never receive an EOF. Default is false |
|
|
Optional: Path at which the file to which the container’s termination message will be written is mounted into the container’s filesystem. Message written is intended to be brief final status, such as an assertion failure message. Will be truncated by the node if greater than 4096 bytes. The total message length across all containers will be limited to 12kb. Defaults to /dev/termination-log. Cannot be updated. |
|
|
Indicate how the termination message should be populated. File will use the contents of terminationMessagePath to populate the container status message on both success and failure. FallbackToLogsOnError will use the last chunk of container log output if the termination message file is empty and the container exited with an error. The log output is limited to 2048 bytes or 80 lines, whichever is smaller. Defaults to File. Cannot be updated. |

PreStop is called immediately before a container is terminated due to an API request or management event such as liveness/startup probe failure, preemption, resource contention, etc. The handler is not called if the container crashes or exits. The reason for termination is passed to the handler. The Pod’s termination grace period countdown begins before the PreStop hooked is executed. Regardless of the outcome of the handler, the container will eventually terminate within the Pod’s termination grace period. Other management of the container blocks until the hook completes or until the termination grace period is reached.

Command is the command line to execute inside the container, the working directory for the command is root ('/') in the container’s filesystem. The command is simply exec’d, it is not run inside a shell, so traditional shell instructions ('|', etc) won’t work. To use a shell, you need to explicitly call out to that shell. Exit status of 0 is treated as live/healthy and non-zero is unhealthy. |

List of ports to expose from the container. Exposing a port here gives the system additional information about the network connections a container uses, but is primarily informational. Not specifying a port here DOES NOT prevent that port from being exposed. Any port which is listening on the default "0.0.0.0" address inside a container will be accessible from the network. Cannot be updated.
