Application Manager setup

The Application Manager is a backend microservice in FlowX.AI that: ✅ Manages FlowX applications, versions, manifests, and configurations.
✅ Acts as a proxy for front-end resource requests.

Infrastructure prerequisites

Before you start setting up the Application Manager service, ensure the following infrastructure components are in place:

Component	Purpose
PostgreSQL	Storing application data
MongoDB	Managing runtime builds
Redis	Caching needs
Kafka	Event-driven communication
OAuth2 Server	Authentication

Ensure that the database for storing application data is properly set up and configured before starting the service.

Dependencies

The Application Manager relies on other FlowX services and components to function properly:

Database configuration: For storing application details, manifests, and configurations.
Authorization & Access Management: For securing access to resources and managing roles.
Kafka Event Bus: For enabling event-driven operations.
Resource Proxy: To forward resource-related requests to appropriate services.

Redis configuration

Application Manager uses Redis for caching when required. Configure Redis connection using the standard Redis environment variables. Quick reference:

Topic naming convention and pattern creation

The Application Manager uses a sophisticated topic naming convention that follows a structured pattern. This ensures consistency across environments and makes topics easily identifiable.

Topic naming components

Component	Default Value	Environment Variable	Description
`package`	`ai.flowx.`	`KAFKA_TOPIC_NAMING_PACKAGE`	Base package identifier
`environment`		`KAFKA_TOPIC_NAMING_ENVIRONMENT`	Deployment environment
`version`	`.v1`	`KAFKA_TOPIC_NAMING_VERSION`	Topic version
`separator`	`.`	`KAFKA_TOPIC_NAMING_SEPARATOR`	Main separator (referred to as `dot`)
`separator2`	`-`	`KAFKA_TOPIC_NAMING_SEPARATOR2`	Secondary separator (as `dash`)
`prefix`	`${KAFKA_TOPIC_NAMING_PACKAGE}${KAFKA_TOPIC_NAMING_ENVIRONMENT}`	`KAFKA_TOPIC_NAMING_PREFIX`	Combined `package` and `environment`
`suffix`	`${KAFKA_TOPIC_NAMING_VERSION}`	`KAFKA_TOPIC_NAMING_SUFFIX`	The version suffix

Topic pattern creation

Topics are constructed using the following pattern:

{prefix} + service + {separator/dot} + action + {separator/dot} + detail + {suffix}

For example, a typical topic might look like:

ai.flowx.application-version.export.v1

Where:

ai.flowx is the prefix (package + environment)
application-version is the service
export is the action
.v1 is the suffix (version)

For more complex topics, additional components are added:

ai.flowx.application-version.resources-usages.sub-res-validation.response.v1

Where:

resources-usages represents the resource type
sub-res-validation represents the operation type
response indicates it’s a response message

Data model overview

The Application Manager stores application data using a relational database schema, with key entities such as application, application_version, and application_manifest. Below are descriptions of primary entities:

Application - Defines an application with its details like name, type, and metadata.
Application Branch - Represents branches for versioning within an application.
Application Version - Keeps track of each version of an application, including committed and WIP statuses.
Application Manifest - Contains the list of resources associated with a specific application version.

Ingress configuration

The Application Manager service uses the standard FlowX.AI ingress pattern. For complete setup instructions including the full ingress template, CORS configuration, and troubleshooting, see the Ingress Configuration Guide. Service-specific values for Application Manager:

Ingress name: application-manager-admin
Service path: /appmanager(/|$)(.*)
Service name: application-manager
Rewrite target: /$2
Fx-Workspace-Id: Required
