### Probe

Probe describes a health check to be performed against a container to determine whether it is alive or ready to receive traffic.

| Name | Type | Description |
| --- | --- | --- |
| `exec` | [Exec Action](#exec-action) | One and only one of the following should be specified. Exec specifies the action to take. |
| `failureThreshold` | integer | Minimum consecutive failures for the probe to be considered failed after having succeeded. Defaults to 3. Minimum value is 1. |
| `httpGet` | [HTTP Get Action](#http-get-action) | HTTPGet specifies the http request to perform. |
| `initialDelaySeconds` | integer | Number of seconds after the container has started before liveness probes are initiated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes |
| `periodSeconds` | integer | How often (in seconds) to perform the probe. Default to 10 seconds. Minimum value is 1. |
| `successThreshold` | integer | Minimum consecutive successes for the probe to be considered successful after having failed. Defaults to 1. Must be 1 for liveness. Minimum value is 1. |
| `tcpSocket` | [TCP Socket Action](#tcp-socket-action) | TCPSocket specifies an action involving a TCP port. TCP hooks not yet supported |
| `timeoutSeconds` | integer | Number of seconds after which the probe times out. Defaults to 1 second. Minimum value is 1. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes |

### Pod Security Context

PodSecurityContext holds pod-level security attributes and common container settings. Some fields are also present in container.securityContext. Field values of container.securityContext take precedence over field values of PodSecurityContext.
