On this [page](https://hub.helm.sh/charts/elastic/elasticsearch) the section on adding a snapshot says:
1. Add any required secrets or credentials into an Elasticsearch keystore following the [how to use the keystore](https://github.com/elastic/helm-charts/tree/7.8/elasticsearch/README.md#how-to-use-the-keystore) guide.
But I am confused as to what to name the secret? For example when creating the `gcs.client.default.credentials_file` I get errors about DNS-1123:
```auto
kubectl create secret generic gcs.client.default.credentials_file --from-file=.gcs-key.json
The Secret "gcs.client.default.credentials_file" is invalid: metadata.name: Invalid value: "gcs.client.default.credentials_file": a DNS-1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')
```
Can someone point me in the right direction here?

Also, copying and pasting the slack\_hook from the example does not work:
```auto
kubectl create secret generic slack_hook --from-literal=xpack.notification.slack.account.monitoring.secure_url='https://hooks.slack.com/services/asdasdasd/asdasdas/asdasd'
The Secret "slack_hook" is invalid: metadata.name: Invalid value: "slack_hook": a DNS-1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')
```

K8S doesn't accept `_` in secret names.
[https://github.com/elastic/helm-charts/issues/811](https://github.com/elastic/helm-charts/issues/811) will fix the examples we provide.
