PodDisruptionBudget is an object to define the max disruption that can be caused to a collection of pods
apiVersion: policy/v1
kind: PodDisruptionBudget
metadata (ObjectMeta)
Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
spec (PodDisruptionBudgetSpec)
Specification of the desired behavior of the PodDisruptionBudget.
status (PodDisruptionBudgetStatus)
Most recently observed status of the PodDisruptionBudget.
PodDisruptionBudgetSpec is a description of a PodDisruptionBudget.
maxUnavailable (IntOrString)
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".
IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.
minAvailable (IntOrString)
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%".
IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.
selector (LabelSelector)
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.
PodDisruptionBudgetStatus represents information about the status of a PodDisruptionBudget. Status may trail the actual state of a system.
currentHealthy (int32), required
current number of healthy pods
desiredHealthy (int32), required
minimum desired number of healthy pods
disruptionsAllowed (int32), required
Number of pod disruptions that are currently allowed.
expectedPods (int32), required
total number of pods counted by this disruption budget
conditions ([]Condition)
Patch strategy: merge on key type
Map: unique values on key type will be kept during a merge
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.
Condition contains details for one aspect of the current state of this API Resource.
conditions.lastTransitionTime (Time), required
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.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
conditions.message (string), required
message is a human readable message indicating details about the transition. This may be an empty string.
conditions.reason (string), required
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.
conditions.status (string), required
status of the condition, one of True, False, Unknown.
conditions.type (string), required
type of condition in CamelCase or in foo.example.com/CamelCase.
conditions.observedGeneration (int64)
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.
disruptedPods (map[string]Time)
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.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
observedGeneration (int64)
Most recent generation observed when updating this PDB status. DisruptionsAllowed and other status information is valid only if observedGeneration equals to PDB's object generation.
PodDisruptionBudgetList is a collection of PodDisruptionBudgets.
