Specification

Property Type Description

apiVersion

string

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

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

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

spec

object

DeploymentSpec is the specification of the desired behavior of the Deployment.

status

object

DeploymentStatus is the most recently observed status of the Deployment.

.spec

Description

DeploymentSpec is the specification of the desired behavior of the Deployment.

Type

object

Required
  • selector

  • template

Property Type Description

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)

paused

boolean

Indicates that the deployment is paused.

progressDeadlineSeconds

integer

The maximum time in seconds for a deployment to make progress before it is considered to be failed. The deployment controller will continue to process failed deployments and a condition with a ProgressDeadlineExceeded reason will be surfaced in the deployment status. Note that progress will not be estimated during the time a deployment is paused. Defaults to 600s.

replicas

integer

Number of desired pods. This is a pointer to distinguish between explicit zero and not specified. Defaults to 1.

revisionHistoryLimit

integer

The number of old ReplicaSets to retain to allow rollback. This is a pointer to distinguish between explicit zero and not specified. Defaults to 10.

selector

LabelSelector

Label selector for pods. Existing ReplicaSets whose pods are selected by this will be the ones affected by this deployment. It must match the pod template’s labels.

strategy

object

DeploymentStrategy describes how to replace existing pods with new ones.

template

PodTemplateSpec

Template describes the pods that will be created. The only allowed template.spec.restartPolicy value is "Always".

.spec.strategy

Description

DeploymentStrategy describes how to replace existing pods with new ones.

Type

object

Property Type Description

rollingUpdate

object

Spec to control the desired behavior of rolling update.

type

string

Type of deployment. Can be "Recreate" or "RollingUpdate". Default is RollingUpdate.

Possible enum values: - "Recreate" Kill all existing pods before creating new ones. - "RollingUpdate" Replace the old ReplicaSets by new one using rolling update i.e gradually scale down the old ReplicaSets and scale up the new one.

.spec.strategy.rollingUpdate

Description

Spec to control the desired behavior of rolling update.

Type

object

Property Type Description

maxSurge

IntOrString

The maximum number of pods that can be scheduled above the desired number of pods. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). This can not be 0 if MaxUnavailable is 0. Absolute number is calculated from percentage by rounding up. Defaults to 25%. Example: when this is set to 30%, the new ReplicaSet can be scaled up immediately when the rolling update starts, such that the total number of old and new pods do not exceed 130% of desired pods. Once old pods have been killed, new ReplicaSet can be scaled up further, ensuring that total number of pods running at any time during the update is at most 130% of desired pods.

maxUnavailable

IntOrString

The maximum number of pods that can be unavailable during the update. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). Absolute number is calculated from percentage by rounding down. This can not be 0 if MaxSurge is 0. Defaults to 25%. Example: when this is set to 30%, the old ReplicaSet can be scaled down to 70% of desired pods immediately when the rolling update starts. Once new pods are ready, old ReplicaSet can be scaled down further, followed by scaling up the new ReplicaSet, ensuring that the total number of pods available at all times during the update is at least 70% of desired pods.

.status

Description

DeploymentStatus is the most recently observed status of the Deployment.

Type

object

Property Type Description

availableReplicas

integer

Total number of available pods (ready for at least minReadySeconds) targeted by this deployment.

collisionCount

integer

Count of hash collisions for the Deployment. The Deployment controller uses this field as a collision avoidance mechanism when it needs to create the name for the newest ReplicaSet.

conditions

array

Represents the latest available observations of a deployment’s current state.

conditions[]

object

DeploymentCondition describes the state of a deployment at a certain point.

observedGeneration

integer

The generation observed by the deployment controller.

readyReplicas

integer

readyReplicas is the number of pods targeted by this Deployment with a Ready Condition.

replicas

integer

Total number of non-terminated pods targeted by this deployment (their labels match the selector).

unavailableReplicas

integer

Total number of unavailable pods targeted by this deployment. This is the total number of pods that are still required for the deployment to have 100% available capacity. They may either be pods that are running but not yet available or pods that still have not been created.

updatedReplicas

integer

Total number of non-terminated pods targeted by this deployment that have the desired template spec.

.status.conditions

Description

Represents the latest available observations of a deployment’s current state.

Type

array

.status.conditions[]

Description

DeploymentCondition describes the state of a deployment at a certain point.

Type

object

Required
  • type

  • status

Property Type Description

lastUpdateTime

Time

message

string

A human readable message indicating details about the transition.

reason

string

The reason for the condition’s last transition.

status

string

type

string

Type of deployment condition.
