.kind

string

Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

.metadata

ObjectMeta meta/v1

Standard object’s metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

.spec

object

Specification of the desired behavior of the Alertmanager cluster. More info: https://github.com/kubernetes/community/blob/master/contributors/devel/sig-architecture/api-conventions.md#spec-and-status

.status

object

Property Type Description

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.

baseImage

string

Base image that is used to deploy pods, without tag.

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[]

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.

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

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.

nodeSelector

object (string)

portName

string

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

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

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.

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.

.spec.storage.volumeClaimTemplate.spec.selector
Description

A label query over volumes to consider for binding.

Type

object

Property Type Description

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.

.spec.storage.volumeClaimTemplate.spec.selector.matchExpressions
Description

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

Type

array

.spec.storage.volumeClaimTemplate.spec.selector.matchExpressions[]

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

Type

object

Required
  • key

  • operator

Property Type Description

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.

.spec.storage.volumeClaimTemplate.status
Description

Status represents the current information/status of a persistent volume claim. Read-only. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#persistentvolumeclaims

Type

object

Property Type Description

accessModes

array (string)

AccessModes contains the actual access modes the volume backing the PVC has. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1

capacity

object (string)

Represents the actual resources of the underlying volume.

conditions

array

Current Condition of persistent volume claim. If underlying persistent volume is being resized then the Condition will be set to 'ResizeStarted'.

conditions[]

object

PersistentVolumeClaimCondition contails details about state of pvc

phase

string

Phase represents the current phase of PersistentVolumeClaim.

.spec.storage.volumeClaimTemplate.status.conditions
Description

Current Condition of persistent volume claim. If underlying persistent volume is being resized then the Condition will be set to 'ResizeStarted'.

Type

array

.spec.storage.volumeClaimTemplate.status.conditions[]
Description

PersistentVolumeClaimCondition contails details about state of pvc

Type

object

Required
  • status

  • type

Property Type Description

lastProbeTime

string

Last time we probed the condition.

lastTransitionTime

string

Last time the condition transitioned from one status to another.

message

string

Human-readable message indicating details about last transition.

reason

string

Unique, this should be a short, machine understandable string that gives the reason for condition’s last transition. If it reports "ResizeStarted" that means the underlying persistent volume is being resized.

status

string

type

string

PersistentVolumeClaimConditionType is a valid value of PersistentVolumeClaimCondition.Type

.spec.tolerations
Description

If specified, the pod's tolerations.

Type

array

.spec.tolerations[]
Description

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

Type

object

Property Type Description

effect

string

Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute.

key

string

Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys.

operator

string

Operator represents a key’s relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category.

tolerationSeconds

integer

TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system.

value

string

Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string.

.spec.volumeMounts
Description

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.

Type

array

.spec.volumeMounts[]
Description

VolumeMount describes a mounting of a Volume within a container.

Type

object

Required
  • mountPath

  • name

Property Type Description

mountPath

string

Path within the container at which the volume should be mounted. Must not contain ':'.

mountPropagation

string

mountPropagation determines how mounts are propagated from the host to container and the other way around. When not set, MountPropagationNone is used. This field is beta in 1.10.

name

string

This must match the Name of a Volume.

readOnly

boolean

Mounted read-only if true, read-write otherwise (false or unspecified). Defaults to false.

subPath

string

Path within the volume from which the container’s volume should be mounted. Defaults to "" (volume’s root).

subPathExpr

string

Expanded path within the volume from which the container’s volume should be mounted. Behaves similarly to SubPath but environment variable references $(VAR_NAME) are expanded using the container’s environment. Defaults to "" (volume’s root). SubPathExpr and SubPath are mutually exclusive.

.spec.volumes
