|
|
ConfigSecret is the name of a Kubernetes Secret in the same namespace as the Alertmanager object, which contains the configuration for this Alertmanager instance. If empty, it defaults to |
|
|
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: |
|
|
A single application container that you want to run within a pod. |
|
|
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 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. |
|
|
Pods' hostAliases configuration |
|
|
HostAlias holds the mapping between IP and hostnames that will be injected as an entry in the pod’s hosts file. |
|
|
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. |
|
|
Image pull policy for the 'alertmanager', 'init-config-reloader' and 'config-reloader' containers. See https://kubernetes.io/docs/concepts/containers/images/#image-pull-policy for more details. |
|

|
|
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 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/ InitContainers described here modify an operator generated init containers if they share the same name and modifications are done via a strategic merge patch. The current init container name is: |
|
|
A single application container that you want to run within a pod. |
|
|
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. |
|
|
Log format for Alertmanager to be configured with. |
|
|
Log level for Alertmanager to be configured with. |
|
|
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 from kubernetes 1.22 until 1.24 which requires enabling the StatefulSetMinReadySeconds feature gate. |
|
|
Define which Nodes the Pods are scheduled on. |
|
|
If set to true all actions on the underlying managed objects are not goint to be performed, except for delete actions. |
|
|
PodMetadata configures labels and annotations which are propagated to the Alertmanager pods. The following items are reserved and cannot be overridden: * "alertmanager" label, set to the name of the Alertmanager instance. * "app.kubernetes.io/instance" label, set to the name of the Alertmanager instance. * "app.kubernetes.io/managed-by" label, set to "prometheus-operator". * "app.kubernetes.io/name" label, set to "alertmanager". * "app.kubernetes.io/version" label, set to the Alertmanager version. * "kubectl.kubernetes.io/default-container" annotation, set to "alertmanager". |
|
|
Port name used for the pods and governing service. Defaults to |
|
|
Priority class assigned to the Pods |
|
|
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. |
|
|
Define resources requests and limits for single Pods. |
|
|
Time duration Alertmanager shall retain data for. Default is '120h', and must match the regular expression |
|
|
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 |
|
|
Secrets is a list of Secrets in the same namespace as the Alertmanager object, which shall be mounted into the Alertmanager Pods. Each Secret is added to the StatefulSet definition as a volume named |
|
|
SecurityContext holds pod-level security attributes and common container settings. This defaults to the default PodSecurityContext. |
|
|
ServiceAccountName is the name of the ServiceAccount to use to run the Prometheus Pods. |
|
|
SHA of Alertmanager container image to be deployed. Defaults to the value of |
|
|
Storage is the definition of how storage will be used by the Alertmanager instances. |
|
|
Tag of Alertmanager container image to be deployed. Defaults to the value of |

The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator <operator>. |
|
|
If specified, the pod’s topology spread constraints. |
|
|
TopologySpreadConstraint specifies how to spread matching pods among the given topology. |
|
|
Version the cluster should be on. |
|
|
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. |
|
|
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. |
|

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.

Arguments to the entrypoint. The container image’s CMD is used if this is not provided. Variable references $(VAR_NAME) are expanded using the container’s environment. If a variable cannot be resolved, the reference in the input string will be unchanged. Double are reduced to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "(VAR_NAME)" will produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless of whether the variable exists or not. Cannot be updated.

List of environment variables to set in the container. Cannot be updated. |
|
|
EnvVar represents an environment variable present in a Container. |
|
|
List of sources to populate environment variables in the container. The keys defined within a source must be a C_IDENTIFIER. All invalid keys will be reported as an event when the container is starting. When a key exists in multiple sources, the value associated with the last source will take precedence. Values defined by an Env with a duplicate key will take precedence. Cannot be updated. |

EnvFromSource represents the source of a set of ConfigMaps |
|
|
Container image name. More info: https://kubernetes.io/docs/concepts/containers/images This field is optional to allow higher level config management to default or override container images in workload controllers like Deployments and StatefulSets. |
|

Image pull policy. One of Always, Never, IfNotPresent. Defaults to Always if :latest tag is specified, or IfNotPresent otherwise. Cannot be updated. More info: https://kubernetes.io/docs/concepts/containers/images#updating-images |

Periodic probe of container liveness. Container will be restarted if the probe fails. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes |
|

Name of the container specified as a DNS_LABEL. Each container in a pod must have a unique name (DNS_LABEL). Cannot be updated. |
|
|
List of ports to expose from the container. 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. Modifying this array with strategic merge patch may corrupt the data. For more information See https://github.com/kubernetes/kubernetes/issues/108255. Cannot be updated. |

ContainerResizePolicy represents resource resize policy for the container. |
|
|
Compute Resources required by this container. Cannot be updated. More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/ |
|
|
RestartPolicy defines the restart behavior of individual containers in a pod. This field may only be set for init containers, and the only allowed value is "Always". For non-init containers or when this field is not specified, the restart behavior is defined by the Pod’s restart policy and the container type. Setting the RestartPolicy as "Always" for the init container will have the following effect: this init container will be continually restarted on exit until all regular containers have terminated. Once all regular containers have completed, all init containers with restartPolicy "Always" will be shut down. This lifecycle differs from normal init containers and is often referred to as a "sidecar" container. Although this init container still starts in the init container sequence, it does not wait for the container to complete before proceeding to the next init container. Instead, the next init container starts immediately after this init container is started, or after any startupProbe has successfully completed. |
|
|
SecurityContext defines the security options the container should be run with. If set, the fields of SecurityContext override the equivalent fields of PodSecurityContext. More info: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/ |
|
|
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. 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. |

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. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes

Optional duration in seconds the pod needs to terminate gracefully upon probe failure. The grace period is the duration in seconds after the processes running in the pod are sent a termination signal and the time when the processes are forcibly halted with a kill signal. Set this value longer than the expected cleanup time for your process. If this value is nil, the pod’s terminationGracePeriodSeconds will be used. Otherwise, this value overrides the value provided by the pod spec. Value must be non-negative integer. The value zero indicates stop immediately via the kill signal (no opportunity to shut down). This is a beta field and requires enabling ProbeTerminationGracePeriod feature gate. Minimum value is 1. spec.terminationGracePeriodSeconds is used if unset. |

RestartPolicy defines the restart behavior of individual containers in a pod. This field may only be set for init containers, and the only allowed value is "Always". For non-init containers or when this field is not specified, the restart behavior is defined by the Pod’s restart policy and the container type. Setting the RestartPolicy as "Always" for the init container will have the following effect: this init container will be continually restarted on exit until all regular containers have terminated. Once all regular containers have completed, all init containers with restartPolicy "Always" will be shut down. This lifecycle differs from normal init containers and is often referred to as a "sidecar" container. Although this init container still starts in the init container sequence, it does not wait for the container to complete before proceeding to the next init container. Instead, the next init container starts immediately after this init container is started, or after any startupProbe has successfully completed. |
|
|
SecurityContext defines the security options the container should be run with. If set, the fields of SecurityContext override the equivalent fields of PodSecurityContext. More info: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/ |

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. 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. |
|
|
Whether this container should allocate a TTY for itself, also requires 'stdin' to be true. Default is false. |

Will be used to create a stand-alone PVC to provision the volume. The pod in which this EphemeralVolumeSource is embedded will be the owner of the PVC, i.e. the PVC will be deleted together with the pod. The name of the PVC will be <pod name>-<volume name>
where <volume name>
is the name from the PodSpec.Volumes
array entry. Pod validation will reject the pod if the concatenated name is not valid for a PVC (for example, too long).
An existing PVC with that name that is not owned by the pod will not be used for the pod to avoid using an unrelated volume by mistake. Starting the pod is then blocked until the unrelated PVC is removed. If such a pre-created PVC is meant to be used by the pod, the PVC has to updated with an owner reference to the pod once the pod exists. Normally this should not be necessary, but it may be useful when manually reconstructing a broken cluster.
This field is read-only and no changes will be made by Kubernetes to the PVC after it has been created.

dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any object from a non-empty API group (non core object) or a PersistentVolumeClaim object. When this field is specified, volume binding will only succeed if the type of the specified object matches some installed volume populator or dynamic provisioner. This field will replace the functionality of the dataSource field and as such if both fields are non-empty, they must have the same value.

When namespace is specified in dataSourceRef, dataSource isn’t set to the same value and must be empty. There are three important differences between dataSource and dataSourceRef: * While dataSource only allows two specific types of objects, dataSourceRef allows any non-core object, as well as PersistentVolumeClaim objects. * While dataSource ignores disallowed values (dropping them), dataSourceRef preserves all values, and generates an error if a disallowed value is specified. * While dataSource only allows local objects, dataSourceRef allows objects in any namespaces.

Valid values are either: * Un-prefixed keys: - storage - the capacity of the volume. * Custom resources must use implementation-defined prefixed names such as "example.com/my-custom-resource" Apart from above values - keys that are unprefixed or have kubernetes.io prefix are considered reserved and hence may not be used. ClaimResourceStatus can be in any of following states: - ControllerResizeInProgress: State set when resize controller starts resizing the volume in control-plane. - ControllerResizeFailed: State set when resize has failed in resize controller with a terminal error. - NodeResizePending: State set when resize controller has finished resizing the volume but further resizing of volume is needed on the node. - NodeResizeInProgress: State set when kubelet starts resizing the volume. - NodeResizeFailed: State set when resizing has failed in kubelet with a terminal error. Transient errors don’t set NodeResizeFailed. For example: if expanding a PVC for more capacity - this field can be one of the following states: - pvc.status.allocatedResourceStatus['storage'] = "ControllerResizeInProgress" - pvc.status.allocatedResourceStatus['storage'] = "ControllerResizeFailed" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizePending" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizeInProgress" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizeFailed" When this field is not set, it means that no resize operation is in progress for the given PVC. A controller that receives PVC update with previously unknown resourceName or ClaimResourceStatus should ignore the update for the purpose it was designed.

allocatedResources tracks the resources allocated to a PVC including its capacity. Key names follow standard Kubernetes label syntax.

Capacity reported here may be larger than the actual capacity when a volume expansion operation is requested. For storage quota, the larger value from allocatedResources and PVC.spec.resources is used. If allocatedResources is not set, PVC.spec.resources alone is used for quota calculation. If a volume expansion capacity request is lowered, allocatedResources is only lowered if there are no expansion operations in progress and if the actual volume capacity is equal or lower than the requested capacity. A controller that receives PVC update with previously unknown resourceName should ignore the update for the purpose it was designed. For example - a controller that only is responsible for resizing capacity of the volume, should ignore PVC updates that change other valid resources associated with PVC.

The same key is forbidden to exist in both MatchLabelKeys and LabelSelector. MatchLabelKeys cannot be set when LabelSelector isn’t set. Keys that don’t exist in the incoming pod labels will be ignored. A null or empty list means only match against labelSelector.
