Property Type Description

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".

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

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.

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

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.
