+= 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 using the
SonataFlowPlarform CR.
+
+== Automate the Jobs Service instance management with the `SonataFlow` Operator
+
+It is possible to deploy the Jobs Service manually, leveraging the Operator
offers a more seamless integration by
+combining it with namespace configuration through the SonataFlowPlatform
Custom Resource (CR). When the Operator oversees
+the lifecycle of the jobs service, it automatically injects necessary
properties during creation into the SonataFlow workflows.
+This integration eliminates the need for including these properties within the
SonataFlow workflow CR instance, simplifying workflow management.
+== Configuring Jobs Service in the SonataFlowPlatform CR
+
+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.
+
+[source,yaml,subs="attributes+"]
+---
+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
+sonataflow-platform-jobs-service-cdf85d969-sbwkj 1/1 Running 0
108s
+---
+
+Keep in mind that this setup is not recommended for production environments,
especially because the data does not persist 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 priority over the one in the `SonataFlowPlatform`
persistence 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.
+
+[source,yaml,subs="attributes+"]
+---
+apiVersion: sonataflow.org/v1alpha08
+kind: SonataFlowPlatform
+metadata:
+ name: sonataflow-platform
+spec:
+ persistence:
+ postgresql:
+ secretRef:
+ name: postgres-secrets
+ userKey: POSTGRES_USER
+ passwordKey: POSTGRES_PASSWORD
+ serviceRef:
+ name: postgres
+ port: 5432
+ databaseName: sonataflow
+---
+
+And the `SonataFlow` CR looks like this:
+
+[source,yaml,subs="attributes+"]
+---
+apiVersion: sonataflow.org/v1alpha08
+kind: SonataFlow
+metadata:
+ name: callbackstatetimeouts
+ annotations:
+ sonataflow.org/description: Callback State Timeouts Example k8s
+ sonataflow.org/version: 0.0.1
+spec:
+ persistence: {}
+...
+---
+
+When using the `jdbcUrl` field instead of `serviceRef`, the user is
responsible for 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.

@gmunozfe please report an enhancement for this suggestion, this is just a
backport of this guide (we moved it out at some point) so please consider
making it nicer in separate PR.
