+= Managing Jobs Service with the Operator
+:compat-mode!:
+// Metadata:
+:description: Configure Jobs Service using the `SonataFlowPlatform` CR.
+:keywords: sonataflow, serverless, operator, kubernetes, jobs service
+
+
+This document describes how to configure the Jobs Service instance usimg the
SonataFlowPlarform CR.
+
+== Automate the Jobs Service instance management with the `SonataFlow` Operator
+
+While it is possible to deploy the Jobs Service manually, the Operator also
provides a convenient way to combine it with the
+namespace configuration via the `SonataFlowPlatform` CR. With this approach,
the Operator will take care of configuring the
+Jobs Service instance and ensure it is in sync with the specification in the
CR. When the operator manages the Jobs Service lifecycle,
+it will inject properties in `SonataFlow` workflows at creation time to enable
the workflows to communicate with the Jobs Service
+instance during their execution, removing the need to add these properties as
part of the `SonataFlow` workflow CR instance.
+
+== Configuring Jobs Service in the SonataFlowPlatformCR
+
+To enable the deployment of a Jobs Service instance, the `SonataFlowPlatform`
CRD exposes a set of fields that allow the user to
+configure the running instance.
+
+==== Ephemeral persistence
+The basic runtime is to deploy the Jobs Service with an ephemeral backend
running in the same container
+as the Jobs Service runtime.

+apiVersion: sonataflow.org/v1alpha08
+kind: SonataFlowPlatform
+metadata:
+ name: sonataflow-platform
+spec:
+ services:
+ jobService: {}
+---
+
+When executing this manifest, the operator will reconcile generating a pod
hosting the Jobs Service:
+
+[source,shell,subs="attributes+"]
+---
+$>kubectl get pod -n sonataflow
+NAME READY STATUS RESTARTS
AGE

108s
+---
+
+Keep in mind that this setup is not recommended for production environments,
chiefly because the data is not persisted when the pod restarts.
+
+==== Using an existing postgreSQL service
+For robust environments it is recommened to use an dedicated database service
and configure Jobs Service to make use of it. Currently, the Jobs Service
+only supports PostgreSQL database.
+
+Configuring Jobs Service to communicate with an existing PostgreSQL instance
is supported in two ways. In both cases it requires providing the persistence
+configuration, one by using the Jobs Service's persistence field and the other
one using the persistence field defined in the `SonataFlowPlatform` CR
+deployed in the same namespace.
+
+By default, the persistence specification defined in the `SonataFlow`
workflow's CR takes precedence over the one in the `SonataFlowPlatform`
persistence's specification.
+
+===== Using the persistence field defined in the `SonataFlowPlatform` CR
+Using the persistence configuration in the `SonataFlowPlatform` CR located in
the same namespace requires to have the `SonataFlow` CR persistence field
configured
+to have an empty `{}` value, signaling the Operator to derive the persistence
from the active `SonataFlowPlatform`, when available. If no persistence is
defined
+the operator will fallback to the ephemeral persistence previously described.

+
+When using the `jdbcUrl` field instead of `serviceRef`, the user is
responsible of providing the correct JDBC URL connection value that does not
contain a `database schema`
+because the operator will use verbatim the contents of this field as the JDBC
connection in the Jobs Service pod, and if it provides a schema that has been
used or formatted
+by a different client, the pod will fail to run.
+
+===== Using the persistency field inside the service specification
+You can specify define the persistence configuration directly in the Jobs
Service specification. The structure is the same as in the `SonataFlowPlatform`
CR and also
