_That's it._ The Helm chart does everything to setup a Vault-on-Kubernetes deployment.
!> **IMPORTANT NOTE:** Vault Helm will not initialize and unseal Vault automatically.
Initialization is required after installation followed by unsealing. Vault can be
configured to auto-unseal using KMS providers such as
[Google Cloud Platform](/docs/platform/k8s/run.html#google-kms-auto-unseal). This
allows the pods to auto unseal if they're rescheduled in Kubernetes.
If standalone or HA mode are being used, the Vault pods must be initialized and unsealed.
For HA deployments, only one of the Vault pods needs to be initialized.
```sh
$ kubectl exec -ti vault-0 -- vault operator init
$ kubectl exec -ti vault-0 -- vault operator unseal
```
For HA deployments, unseal the remaining pods:
```sh
$ kubectl exec -ti <NAME OF POD> -- vault operator unseal
```

In order to authenticate and use KMS in Google Cloud, Vault Helm needs credentials. The `credentials.json`
file will need to be mounted as a secret to the Vault container.
