# io.k8s.api.core.v1.LifecycleHandler

From **Kubernetes**.

LifecycleHandler defines a specific action that should be taken in a lifecycle hook. One and only one of the fields, except TCPSocket must be specified.

- Type: `object`

## Properties

### `exec`

- Required: false
Exec specifies a command to execute in the container.

### `httpGet`

- Required: false
HTTPGet specifies an HTTP GET request to perform.

### `sleep`

- Required: false
Sleep represents a duration that the container should sleep.

### `tcpSocket`

- Required: false
Deprecated. TCPSocket is NOT supported as a LifecycleHandler and kept for backward compatibility. There is no validation of this field and lifecycle hooks will fail at runtime when it is specified.
