resources.podDisruptionBudgets

PodDisruptionBudget is an object to define the max disruption that can be caused to a collection of pods

Type: attribute set of (submodule)

Default: { }

Declared by:

resources.podDisruptionBudgets.<name>.apiVersion

APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.kind

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

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.metadata

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

Type: null or (submodule)

Declared by:

resources.podDisruptionBudgets.<name>.metadata.annotations

Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations

Type: null or (attribute set of (string))

Declared by:

resources.podDisruptionBudgets.<name>.metadata.creationTimestamp

CreationTimestamp is a timestamp representing the server time when this object was created. It is not guaranteed to be set in happens-before order across separate operations. Clients may not set this value. It is represented in RFC3339 form and is in UTC.

Populated by the system. Read-only. Null for lists. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.metadata.deletionGracePeriodSeconds

Number of seconds allowed for this object to gracefully terminate before it will be removed from the system. Only set when deletionTimestamp is also set. May only be shortened. Read-only.

Type: null or signed integer

Declared by:

resources.podDisruptionBudgets.<name>.metadata.deletionTimestamp

DeletionTimestamp is RFC 3339 date and time at which this resource will be deleted. This field is set by the server when a graceful deletion is requested by the user, and is not directly settable by a client. The resource is expected to be deleted (no longer visible from resource lists, and not reachable by name) after the time in this field, once the finalizers list is empty. As long as the finalizers list contains items, deletion is blocked. Once the deletionTimestamp is set, this value may not be unset or be set further into the future, although it may be shortened or the resource may be deleted prior to this time. For example, a user may request that a pod is deleted in 30 seconds. The Kubelet will react by sending a graceful termination signal to the containers in the pod. After that 30 seconds, the Kubelet will send a hard termination signal (SIGKILL) to the container and after cleanup, remove the pod from the API. In the presence of network partitions, this object may still exist after this timestamp, until an administrator or automated process can determine the resource is fully terminated. If not set, graceful deletion of the object has not been requested.

Populated by the system when a graceful deletion is requested. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.metadata.finalizers

Must be empty before the object is deleted from the registry. Each entry is an identifier for the responsible component that will remove the entry from the list. If the deletionTimestamp of the object is non-nil, entries in this list can only be removed. Finalizers may be processed and removed in any order. Order is NOT enforced because it introduces significant risk of stuck finalizers. finalizers is a shared field, any actor with permission can reorder it. If the finalizer list is processed in order, then this can lead to a situation in which the component responsible for the first finalizer in the list is waiting for a signal (field value, external system, or other) produced by a component responsible for a finalizer later in the list, resulting in a deadlock. Without enforced ordering finalizers are free to order amongst themselves and are not vulnerable to ordering changes in the list.

Type: null or (list of (string))

Declared by:

resources.podDisruptionBudgets.<name>.metadata.generateName

GenerateName is an optional prefix, used by the server, to generate a unique name ONLY IF the Name field has not been provided. If this field is used, the name returned to the client will be different than the name passed. This value will also be combined with a unique suffix. The provided value has the same validation rules as the Name field, and may be truncated by the length of the suffix required to make the value unique on the server.

If this field is specified and the generated name exists, the server will return a 409.

Applied only if Name is not specified. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#idempotency

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.metadata.generation

A sequence number representing a specific generation of the desired state. Populated by the system. Read-only.

Type: null or signed integer

Declared by:

resources.podDisruptionBudgets.<name>.metadata.labels

Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels

Type: null or (attribute set of (string))

Declared by:

resources.podDisruptionBudgets.<name>.metadata.managedFields

ManagedFields maps workflow-id and version to the set of fields that are managed by that workflow. This is mostly for internal housekeeping, and users typically shouldn’t need to set or understand this field. A workflow can be the user’s name, a controller’s name, or the name of a specific apply path like “ci-cd”. The set of fields is always in the version that the workflow used when modifying the object.

Type: null or (list of (submodule))

Declared by:

resources.podDisruptionBudgets.<name>.metadata.managedFields.*.apiVersion

APIVersion defines the version of this resource that this field set applies to. The format is “group/version” just like the top-level APIVersion field. It is necessary to track the version of a field set because it cannot be automatically converted.

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.metadata.managedFields.*.fieldsType

FieldsType is the discriminator for the different fields format and version. There is currently only one possible value: “FieldsV1”

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.metadata.managedFields.*.fieldsV1

FieldsV1 holds the first JSON version format as described in the “FieldsV1” type.

Type: null or (submodule)

Declared by:

resources.podDisruptionBudgets.<name>.metadata.managedFields.*.manager

Manager is an identifier of the workflow managing these fields.

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.metadata.managedFields.*.operation

Operation is the type of operation which lead to this ManagedFieldsEntry being created. The only valid values for this field are ‘Apply’ and ‘Update’.

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.metadata.managedFields.*.subresource

Subresource is the name of the subresource used to update that object, or empty string if the object was updated through the main resource. The value of this field is used to distinguish between managers, even if they share the same name. For example, a status update will be distinct from a regular update using the same manager name. Note that the APIVersion field is not related to the Subresource field and it always corresponds to the version of the main resource.

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.metadata.managedFields.*.time

Time is the timestamp of when the ManagedFields entry was added. The timestamp will also be updated if a field is added, the manager changes any of the owned fields value or removes a field. The timestamp does not update when a field is removed from the entry because another manager took it over.

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.metadata.name

Name must be unique within a namespace. Is required when creating resources, although some resources may allow a client to request the generation of an appropriate name automatically. Name is primarily intended for creation idempotence and configuration definition. Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#names

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.metadata.namespace

Namespace defines the space within which each name must be unique. An empty namespace is equivalent to the “default” namespace, but “default” is the canonical representation. Not all objects are required to be scoped to a namespace - the value of this field for those objects will be empty.

Must be a DNS_LABEL. Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.metadata.ownerReferences

List of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller.

Type: null or (attribute set of (submodule) or list of (submodule))

Declared by:

resources.podDisruptionBudgets.<name>.metadata.ownerReferences.<name>._priority

This option has no description.

Type: null or signed integer

API version of the referent.

Type: string

Declared by:

resources.podDisruptionBudgets.<name>.metadata.ownerReferences.<name>.blockOwnerDeletion

If true, AND if the owner has the “foregroundDeletion” finalizer, then the owner cannot be deleted from the key-value store until this reference is removed. See https://kubernetes.io/docs/concepts/architecture/garbage-collection/#foreground-deletion for how the garbage collector interacts with this field and enforces the foreground deletion. Defaults to false. To set this field, a user needs “delete” permission of the owner, otherwise 422 (Unprocessable Entity) will be returned.

Declared by:

resources.podDisruptionBudgets.<name>.metadata.resourceVersion

An opaque value that represents the internal version of this object that can be used by clients to determine when objects have changed.

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.spec

Specification of the desired behavior of the PodDisruptionBudget.

Type: null or (submodule)

Declared by:

resources.podDisruptionBudgets.<name>.spec.maxUnavailable

An eviction is allowed if at most “maxUnavailable” pods selected by “selector” are unavailable after the eviction, i.e. even in absence of the evicted pod. For example, one can prevent all voluntary evictions by specifying 0. This is a mutually exclusive setting with “minAvailable”.

Type: null or signed integer or (string)

Declared by:

resources.podDisruptionBudgets.<name>.spec.minAvailable

An eviction is allowed if at least “minAvailable” pods selected by “selector” will still be available after the eviction, i.e. even in the absence of the evicted pod. So for example you can prevent all voluntary evictions by specifying “100%”.

Type: null or signed integer or (string)

Declared by:

resources.podDisruptionBudgets.<name>.spec.selector

Label query over pods whose evictions are managed by the disruption budget. A null selector will match no pods, while an empty ({}) selector will select all pods within the namespace.

Type: null or (submodule)

Declared by:

resources.podDisruptionBudgets.<name>.spec.selector.matchExpressions

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

Type: null or (list of (submodule))

Declared by:

resources.podDisruptionBudgets.<name>.spec.selector.matchExpressions.*.key

key is the label key that the selector applies to.

Type: string

Declared by:

resources.podDisruptionBudgets.<name>.spec.selector.matchExpressions.*.operator

operator represents a key’s relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.

Type: string

Declared by:

resources.podDisruptionBudgets.<name>.spec.selector.matchExpressions.*.values

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.

Type: null or (list of (string))

Declared by:

resources.podDisruptionBudgets.<name>.spec.selector.matchLabels

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.

Type: null or (attribute set of (string))

Declared by:

resources.podDisruptionBudgets.<name>.spec.unhealthyPodEvictionPolicy

UnhealthyPodEvictionPolicy defines the criteria for when unhealthy pods should be considered for eviction. Current implementation considers healthy pods, as pods that have status.conditions item with type=“Ready”,status=“True”.

Valid policies are IfHealthyBudget and AlwaysAllow. If no policy is specified, the default behavior will be used, which corresponds to the IfHealthyBudget policy.

IfHealthyBudget policy means that running pods (status.phase=“Running”), but not yet healthy can be evicted only if the guarded application is not disrupted (status.currentHealthy is at least equal to status.desiredHealthy). Healthy pods will be subject to the PDB for eviction.

AlwaysAllow policy means that all running pods (status.phase=“Running”), but not yet healthy are considered disrupted and can be evicted regardless of whether the criteria in a PDB is met. This means perspective running pods of a disrupted application might not get a chance to become healthy. Healthy pods will be subject to the PDB for eviction.

Additional policies may be added in the future. Clients making eviction decisions should disallow eviction of unhealthy pods if they encounter an unrecognized policy in this field.

This field is beta-level. The eviction API uses this field when the feature gate PDBUnhealthyPodEvictionPolicy is enabled (enabled by default).

Type: null or (string)

Declared by:

resources.podDisruptionBudgets.<name>.status

Most recently observed status of the PodDisruptionBudget.

Type: null or (submodule)

Declared by:

resources.podDisruptionBudgets.<name>.status.conditions

Conditions contain conditions for PDB. The disruption controller sets the DisruptionAllowed condition. The following are known values for the reason field (additional reasons could be added in the future): - SyncFailed: The controller encountered an error and wasn’t able to compute the number of allowed disruptions. Therefore no disruptions are allowed and the status of the condition will be False.

  • InsufficientPods: The number of pods are either at or below the number required by the PodDisruptionBudget. No disruptions are allowed and the status of the condition will be False.
  • SufficientPods: There are more pods than required by the PodDisruptionBudget. The condition will be True, and the number of allowed disruptions are provided by the disruptionsAllowed property.

Type: null or (attribute set of (submodule) or list of (submodule))

Declared by:

resources.podDisruptionBudgets.<name>.status.conditions.<name>._priority

This option has no description.

Type: null or signed integer

Default: null

Declared by:

resources.podDisruptionBudgets.<name>.status.conditions.<name>.lastTransitionTime

lastTransitionTime is the last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.

Type: string

Declared by:

resources.podDisruptionBudgets.<name>.status.conditions.<name>.message

message is a human readable message indicating details about the transition. This may be an empty string.

Type: string

Declared by:

resources.podDisruptionBudgets.<name>.status.conditions.<name>.observedGeneration

observedGeneration represents the .metadata.generation that the condition was set based upon. For instance, if .metadata.generation is currently 12, but the .status.conditions[x].observedGeneration is 9, the condition is out of date with respect to the current state of the instance.

Type: null or signed integer

Declared by:

resources.podDisruptionBudgets.<name>.status.conditions.<name>.reason

reason contains a programmatic identifier indicating the reason for the condition’s last transition. Producers of specific condition types may define expected values and meanings for this field, and whether the values are considered a guaranteed API. The value should be a CamelCase string. This field may not be empty.

Type: string

Declared by:

resources.podDisruptionBudgets.<name>.status.conditions.<name>.status

status of the condition, one of True, False, Unknown.

Type: string

Declared by:

resources.podDisruptionBudgets.<name>.status.conditions.<name>.type

Declared by:

resources.podDisruptionBudgets.<name>.status.currentHealthy

current number of healthy pods

Type: signed integer

Declared by:

resources.podDisruptionBudgets.<name>.status.desiredHealthy

minimum desired number of healthy pods

Type: signed integer

Declared by:

resources.podDisruptionBudgets.<name>.status.disruptedPods

DisruptedPods contains information about pods whose eviction was processed by the API server eviction subresource handler but has not yet been observed by the PodDisruptionBudget controller. A pod will be in this map from the time when the API server processed the eviction request to the time when the pod is seen by PDB controller as having been marked for deletion (or after a timeout). The key in the map is the name of the pod and the value is the time when the API server processed the eviction request. If the deletion didn’t occur and a pod is still there it will be removed from the list automatically by PodDisruptionBudget controller after some time. If everything goes smooth this map should be empty for the most of the time. Large number of entries in the map may indicate problems with pod deletions.

Type: null or (attribute set of (string))

Declared by:

resources.podDisruptionBudgets.<name>.status.disruptionsAllowed

Number of pod disruptions that are currently allowed.

Type: signed integer

Declared by:

total number of pods counted by this disruption budget

Type: signed integer

Declared by:

resources.podDisruptionBudgets.<name>.status.observedGeneration
