Type

object

Property Type Description

affinity

object

If specified, the pod’s scheduling constraints.

alertDropLabels

array (string)

AlertDropLabels configure the label names which should be dropped in ThanosRuler alerts. If labels field is not provided, thanos_ruler_replica will be dropped in alerts by default.

alertQueryUrl

string

The external Query URL the Thanos Ruler will set in the 'Source' field of all alerts. Maps to the '--alert.query-url' CLI arg.

alertmanagersConfig

object

Define configuration for connecting to alertmanager. Only available with thanos v0.10.0 and higher. Maps to the alertmanagers.config arg.

alertmanagersUrl

array (string)

Define URLs to send alerts to Alertmanager. For Thanos v0.10.0 and higher, AlertManagersConfig should be used instead. Note: this field will be ignored if AlertManagersConfig is specified. Maps to the alertmanagers.url arg.

containers

array

Containers allows injecting additional containers or modifying operator generated containers. This can be used to allow adding an authentication proxy to a ThanosRuler 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: thanos-ruler and config-reloader. 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

A single application container that you want to run within a pod.

enforcedNamespaceLabel

string

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.

evaluationInterval

string

Interval between consecutive evaluations.

externalPrefix

string

The external URL the Thanos Ruler instances will be available under. This is necessary to generate correct URLs. This is necessary if Thanos Ruler is not served from root of a DNS name.

grpcServerTlsConfig

object

GRPCServerTLSConfig configures the gRPC server from which Thanos Querier reads recorded rule data. Note: Currently only the CAFile, CertFile, and KeyFile fields are supported. Maps to the '--grpc-server-tls-*' CLI args.

string

Thanos container image URL.

imagePullSecrets

array

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

imagePullSecrets[]

object

LocalObjectReference contains enough information to let you locate the referenced object inside the same namespace.

initContainers

array

InitContainers allows adding initContainers to the pod definition. Those can be used to e.g. fetch secrets for injection into the ThanosRuler 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.

initContainers[]

object

A single application container that you want to run within a pod.

labels

object (string)

Labels configure the external label pairs to ThanosRuler. If not provided, default replica label thanos_ruler_replica will be added as a label and be dropped in alerts.

listenLocal

boolean

ListenLocal makes the Thanos ruler listen on loopback, so that it does not bind against the Pod IP.

logFormat

string

Log format for ThanosRuler to be configured with.

logLevel

string

Log level for ThanosRuler to be configured with.

minReadySeconds

integer

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 and requires enabling StatefulSetMinReadySeconds feature gate.

object (string)

Define which Nodes the Pods are scheduled on.

objectStorageConfig

object

ObjectStorageConfig configures object storage in Thanos. Alternative to ObjectStorageConfigFile, and lower order priority.

objectStorageConfigFile

paused

boolean

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

podMetadata

object

PodMetadata contains Labels and Annotations gets propagated to the thanos ruler pods.

portName

string

Port name used for the pods and governing service. This defaults to web

priorityClassName

string

Priority class assigned to the Pods

prometheusRulesExcludedFromEnforce

array

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

prometheusRulesExcludedFromEnforce[]

object

PrometheusRuleExcludeConfig enables users to configure excluded PrometheusRule names and their namespaces to be ignored while enforcing namespace label for alerts and metrics.

queryConfig

object

Define configuration for connecting to thanos query instances. If this is defined, the QueryEndpoints field will be ignored. Maps to the query.config CLI argument. Only available with thanos v0.11.0 and higher.

queryEndpoints

array (string)

QueryEndpoints defines Thanos querier endpoints from which to query metrics. Maps to the --query flag of thanos ruler.

replicas

integer

Number of thanos ruler instances to deploy.

resources

object

Resources defines the resource requirements for single Pods. If not provided, no requests/limits will be set

retention

routePrefix

string

The route prefix ThanosRuler registers HTTP handlers for. This allows thanos UI to be served on a sub-path.

ruleNamespaceSelector

Namespaces to be selected for Rules discovery. If unspecified, only the same namespace as the ThanosRuler object is in is used.

ruleSelector

object

A label selector to select which PrometheusRules to mount for alerting and recording.

securityContext

topologySpreadConstraints[]

object

TopologySpreadConstraint specifies how to spread matching pods among the given topology.

tracingConfig

object

TracingConfig configures tracing in Thanos. This is an experimental feature, it may change in any upcoming release in a breaking way.

object

Property Type Description

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 matches the corresponding matchExpressions; the node(s) with the highest sum are the most preferred.

object

An empty preferred scheduling term matches all objects with implicit weight 0 (i.e. it’s a no-op). A null preferred scheduling term matches no objects (i.e. is also a no-op).

requiredDuringSchedulingIgnoredDuringExecution

object

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 an update), the system may or may not try to eventually evict the pod from its node.

.spec.affinity.nodeAffinity.preferredDuringSchedulingIgnoredDuringExecution
