* `POSTGRES_PASSWORD` - Database password
* `POSTGRES_SUPERUSER` - Indicates, whether backups should run as super user. Typically `true`.
* `POSTGRES_SUPERUSER` - Indicates whether backups should run as super user. Typically `true`.
* `SSL_MODE` - Indicates whether to use TLS on the connection to the external PostgreSQL database. Check the possible https://www.postgresql.org/docs/current/libpq-ssl.html[values]
When `SSL_MODE` is enabled, the operator searches for a secret called `keycloak-db-ssl-cert-secret` containing the `root.crt` that has been used by the PostgreSQL database. Creating the secret is optional and the secret is used only when you want to verify the Database's certificate (for example `SSLMODE: verify-ca`). Here is an example :
.Example YAML file for `TLS Secret` to be used by the operator.
```yaml
apiVersion: v1
kind: Secret
metadata:
name: keycloak-db-ssl-cert-secret
namespace: keycloak
type: Opaque
data:
root.crt: {root.crt base64}
```
The Operator will create a Service named `keycloak-postgresql`. This Service is configured by the Operator to expose the external database based on the content of `POSTGRES_EXTERNAL_ADDRESS`. {project_name} uses this Service to connect to the Database, which means it does not connect to the Database directly but rather through this Service.
