Alertmanager [monitoring.coreos.com/v1]

additionalPeers

array (string)

AdditionalPeers allows injecting a set of additional Alertmanagers to peer with to form a highly available cluster.

affinity

object

If specified, the pod’s scheduling constraints.

alertmanagerConfigNamespaceSelector

object

Namespaces to be selected for AlertmanagerConfig discovery. If nil, only check own namespace.

alertmanagerConfigSelector

object

AlertmanagerConfigs to be selected for to merge and configure Alertmanager with.

baseImage

string

Base image that is used to deploy pods, without tag. Deprecated: use 'image' instead

clusterAdvertiseAddress

string

ClusterAdvertiseAddress is the explicit address to advertise in cluster. Needs to be provided for non RFC1918 [1] (public) addresses. [1] RFC1918: https://tools.ietf.org/html/rfc1918

clusterGossipInterval

string

Interval between gossip attempts.

clusterPeerTimeout

string

Timeout for cluster peering.

clusterPushpullInterval

string

Interval between pushpull attempts.

configMaps

array (string)

ConfigMaps is a list of ConfigMaps in the same namespace as the Alertmanager object, which shall be mounted into the Alertmanager Pods. The ConfigMaps are mounted into /etc/alertmanager/configmaps/<configmap-name>.

configSecret

string

ConfigSecret is the name of a Kubernetes Secret in the same namespace as the Alertmanager object, which contains configuration for this Alertmanager instance. Defaults to 'alertmanager-<alertmanager-name>' The secret is mounted into /etc/alertmanager/config.

containers

array

Containers allows injecting additional containers. This is meant to allow adding an authentication proxy to an Alertmanager pod. 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: alertmanager 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.

externalUrl

string

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

forceEnableClusterMode

boolean

ForceEnableClusterMode ensures Alertmanager does not deactivate the cluster mode when running with a single replica. Use case is e.g. spanning an Alertmanager cluster across Kubernetes clusters with a single replica in each.

image

string

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 Alertmanager is being configured.

imagePullSecrets

array

An optional list of references to secrets in the same namespace to use for pulling prometheus and alertmanager 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 Alertmanager 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.

listenLocal

boolean

ListenLocal makes the Alertmanager server listen on loopback, so that it does not bind against the Pod IP. Note this is only for the Alertmanager UI, not the gossip communication.

logFormat

string

Log format for Alertmanager to be configured with.

logLevel

string

Log level for Alertmanager 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.

nodeSelector

object (string)

Define which Nodes the Pods are scheduled on.

paused

boolean

If set to true all actions on the underlying managed objects are not goint to be performed, except for delete actions.

podMetadata

object

PodMetadata configures Labels and Annotations which are propagated to the alertmanager pods.

portName

string

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

priorityClassName

string

Priority class assigned to the Pods

replicas

integer

Size is the expected size of the alertmanager cluster. The controller will eventually make the size of the running cluster equal to the expected size.

resources

object

Define resources requests and limits for single Pods.

retention

string

Time duration Alertmanager shall retain data for. Default is '120h', and must match the regular expression [0-9]+(ms|s|m|h) (milliseconds seconds minutes hours).

routePrefix

string

The route prefix Alertmanager 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 kubectl proxy.

secrets

array (string)

Secrets is a list of Secrets in the same namespace as the Alertmanager object, which shall be mounted into the Alertmanager Pods. The Secrets are mounted into /etc/alertmanager/secrets/<secret-name>.

securityContext

object

SecurityContext holds pod-level security attributes and common container settings. This defaults to the default PodSecurityContext.

serviceAccountName

string

ServiceAccountName is the name of the ServiceAccount to use to run the Prometheus Pods.

sha

string

SHA of Alertmanager 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.

storage

object

Storage is the definition of how storage will be used by the Alertmanager instances.

tag

string

Tag of Alertmanager container image to be deployed. Defaults to the value of version. Version is ignored if Tag is set. Deprecated: use 'image' instead. The image tag can be specified as part of the image URL.

tolerations

array

If specified, the pod’s tolerations.

tolerations[]

object

The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator <operator>.

topologySpreadConstraints

array

If specified, the pod’s topology spread constraints.

topologySpreadConstraints[]

object

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

version

string

Version the cluster should be on.

volumeMounts

array

VolumeMounts allows configuration of additional VolumeMounts on the output StatefulSet definition. VolumeMounts specified will be appended to other VolumeMounts in the alertmanager container, that are generated as a result of StorageSpec objects.

volumeMounts[]

object

VolumeMount describes a mounting of a Volume within a container.

volumes

array

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.

volumes[]

object

Volume represents a named volume in a pod that may be accessed by any container in the pod.

nodeAffinity

object

Describes node affinity scheduling rules for the pod.

podAffinity

object

Describes pod affinity scheduling rules (e.g. co-locate this pod in the same node, zone, etc. as some other pod(s)).

podAntiAffinity

object

Describes pod anti-affinity scheduling rules (e.g. avoid putting this pod in the same node, zone, etc. as some other pod(s)).

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.

preferredDuringSchedulingIgnoredDuringExecution[]

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.

preference

object

A node selector term, associated with the corresponding weight.

weight

integer

Weight associated with matching the corresponding nodeSelectorTerm, in the range 1-100.

matchExpressions

array
