### Cert Manager Helm Installation Output

Source: https://github.com/k8ssandra/k8ssandra-operator/blob/main/docs/content/en/install/gke/_index.md

Example output from a successful Cert Manager Helm installation. It confirms the deployment and provides links to further documentation for configuring issuers and certificates.

```text
NAME: cert-manager
LAST DEPLOYED: Mon Jan 31 12:29:43 2022
NAMESPACE: cert-manager
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
cert-manager v1.7.0 has been deployed successfully!

In order to begin issuing certificates, you will need to set up a ClusterIssuer
or Issuer resource (for example, by creating a 'letsencrypt-staging' issuer).

More information on the different types of issuers and how to configure them
can be found in our documentation:

https://cert-manager.io/docs/configuration/

For information on how to configure cert-manager to automatically provision
Certificates for Ingress resources, take a look at the `ingress-shim`

If specified, no other probes are executed until this completes successfully. If this probe fails, the Pod will be restarted, just as if the livenessProbe failed.

```APIDOC
## CassandraBackup StartupProbe Configuration

### Description
StartupProbe indicates that the Pod has successfully initialized. If specified, no other probes are executed until this completes successfully. If this probe fails, the Pod will be restarted, just as if the livenessProbe failed. This can be used to provide different probe parameters at the beginning of a Pod's lifecycle, when it might take a long time to load data or warm a cache, than during steady-state operation. This cannot be updated.

### Endpoint
N/A (Configuration within a resource definition)

### Parameters
#### Request Body (within CassandraBackup resource definition)
- **exec** (object) - Optional - One and only one of the following should be specified. Exec specifies the action to take.
- **failureThreshold** (integer) - Optional - Minimum consecutive failures for the probe to be considered failed after having succeeded. Defaults to 3. Minimum value is 1.
- **httpGet** (object) - Optional - HTTPGet specifies the http request to perform.
- **initialDelaySeconds** (integer) - Optional - Number of seconds after the container has started before liveness probes are initiated. Defaults to 0.
- **periodSeconds** (integer) - Optional - How often (in seconds) to perform the probe. Default to 10 seconds. Minimum value is 1.
- **successThreshold** (integer) - Optional - Minimum consecutive successes for the probe to be considered successful after having failed. Defaults to 1. Must be 1 for liveness and startup. Minimum value is 1.
- **tcpSocket** (object) - Optional - TCPSocket specifies an action involving a TCP port. TCP hooks not yet supported.
- **terminationGracePeriodSeconds** (integer) - Optional - Optional duration in seconds the pod needs to terminate gracefully upon probe failure. The grace period is the duration in seconds after the processes running in the pod are sent a termination signal and the time when the processes are forcibly halted with a kill signal. Value must be non-negative integer. The value zero indicates stop immediately via the kill signal (no opportunity to shut down). Minimum value is 1.
- **timeoutSeconds** (integer) - Optional - Number of seconds after which the probe times out. Defaults to 1 second. Minimum value is 1.

### Request Example
```json

### CassandraBackup initContainer StartupProbe Configuration

Source: https://github.com/k8ssandra/k8ssandra-operator/blob/main/docs/content/en/reference/crd/k8ssandra-operator-crds-latest/_index.md

Configuration details for the startupProbe within the initContainers of a CassandraBackup's podTemplateSpec.

```APIDOC
## StartupProbe Configuration for CassandraBackup initContainers

### Description
StartupProbe indicates that the Pod has successfully initialized. If specified, no other probes are executed until this completes successfully. If this probe fails, the Pod will be restarted, just as if the livenessProbe failed. This can be used to provide different probe parameters at the beginning of a Pod's lifecycle, when it might take a long time to load data or warm a cache, than during steady-state operation. This cannot be updated.

### Endpoint
N/A (Configuration within a Kubernetes resource definition)

### Parameters
#### Request Body (within `spec.podTemplateSpec.spec.initContainers[index].startupProbe`)
- **exec** (object) - Optional - Exec specifies the action to take.
- **failureThreshold** (integer) - Optional - Minimum consecutive failures for the probe to be considered failed after having succeeded. Defaults to 3. Minimum value is 1.
- **grpc** (object) - Optional - GRPC specifies an action involving a GRPC port. This is a beta field and requires enabling GRPCContainerProbe feature gate.
- **httpGet** (object) - Optional - HTTPGet specifies the http request to perform.
- **initialDelaySeconds** (integer) - Optional - Number of seconds after the container has started before liveness probes are initiated. Defaults to 0. Minimum value is 0.
- **periodSeconds** (integer) - Optional - How often (in seconds) to perform the probe. Default to 10 seconds. Minimum value is 1.
- **successThreshold** (integer) - Optional - Minimum consecutive successes for the probe to be considered successful after having failed. Defaults to 1. Must be 1 for liveness and startup. Minimum value is 1.
- **tcpSocket** (object) - Optional - TCPSocket specifies an action involving a TCP port.
- **terminationGracePeriodSeconds** (integer) - Optional - Optional duration in seconds the pod needs to terminate gracefully upon probe failure. The grace period is the duration in seconds after the processes running in the pod are sent a termination signal and the time when the processes are forcibly halted with a kill signal. Set this value longer than the expected cleanup time for your process. If this value is nil, the pod's terminationGracePeriodSeconds will be used. Otherwise, this value overrides the value provided by the pod spec. Value must be non-negative integer. The value zero indicates stop immediately via the kill signal (no opportunity to shut down). This is a beta field and requires enabling ProbeTerminationGracePeriod feature gate. Minimum value is 1.
- **timeoutSeconds** (integer) - Optional - Number of seconds after which the probe times out. Defaults to 1 second. Minimum value is 1.

### Request Example
```json
{
  "exec": {
    "command": [
      "cqlsh",
      "-e",
      "SELECT 1;"
    ]
  },
  "initialDelaySeconds": 5,
  "periodSeconds": 10,
  "timeoutSeconds": 1,
  "failureThreshold": 3,
  "successThreshold": 1
