​
Infrastructure prerequisites

The Runtime Manager service requires the following components to be set up before it can be started:
  • PostgreSQL - version 13 or higher for managing application data
  • MongoDB - version 4.4 or higher for managing runtime data
  • Redis - version 6.0 or higher (if required)
  • Kafka - version 2.8 or higher for event-driven communication between services
  • OAuth2 Authentication - Ensure a compatible OAuth2 authorization server is configured.

​
Dependencies

​
Configuration

​
General environment variables

The following environment variables provide essential configurations:
  • LOGGING_CONFIG_FILE - Path to the logging configuration file for customized logging levels.
  • SPRING_APPLICATION_NAME - Sets the application name.
    • Default Value: application-manager -> must be changed to runtime-manager.

​
Database configuration

The Runtime Manager uses the same PostgreSQL (to store application data) and MongoDB (to manage runtime data) as application-manager. Configure these database connections with the following environment variables:

​
PostgreSQL (Application data)

  • SPRING_DATASOURCE_URL - Database URL for the PostgreSQL data source (same as the one configured in application-manager setup)

​
MongoDB (Runtime data)

  • SPRING_DATA_MONGODB_URI - URI for connecting to MongoDB for runtime data (same as the one configured in application-manager setup)
    • Format: mongodb://${DB_USERNAME}:${DB_PASSWORD}@<host1>,<host2>,<arbiter-host>:<port>/${DB_NAME}?retryWrites=false
  • DB_USERNAME: app-runtime
  • DB_NAME: app-runtime
  • DB_PASSWORD: DB password.

​
Configuring Kafka

Kafka is used for event-driven operations within the Runtime Handler. Set up the Kafka configuration using the following environment variables:
  • SPRING_KAFKA_BOOTSTRAP_SERVERS - Address of the Kafka server in the format host:port
  • KAFKA_TOPIC_NAMING_ENVIRONMENT - Environment-specific suffix for Kafka topics

​
Kafka OAuth Authentication

To securely integrate with Kafka, configure the following OAuth credentials:
  • KAFKA_OAUTH_CLIENT_ID - OAuth Client ID for Kafka
  • KAFKA_OAUTH_CLIENT_SECRET - OAuth Client Secret for Kafka
  • KAFKA_OAUTH_TOKEN_ENDPOINT_URI - OAuth Token Endpoint URI for obtaining Kafka tokens
    • Format: https://<auth-server>/auth/realms/<realm>/protocol/openid-connect/token

​
Configuring authentication and access roles

Runtime Handler uses OAuth2 for secure access control. Set up the OAuth2 configurations with the following environment variables:
  • SECURITY_OAUTH2_BASE_SERVER_URL - Base URL for the OAuth 2.0 Authorization Server
  • SECURITY_OAUTH2_CLIENT_CLIENT_ID - Unique identifier for the client application registered with the OAuth 2.0 server
  • SECURITY_OAUTH2_CLIENT_CLIENT_SECRET - Secret key for authenticating requests made by the authorization client
  • SECURITY_OAUTH2_REALM - The realm name for OAuth2 authentication

​
Redis configuration (optional)

If Redis is required for caching, set the following environment variable:
  • SPRING_REDIS_HOST - Hostname or IP address of the Redis server

​
Configuring file storage

For file storage needs, configure the S3-compatible storage with the following environment variable:
  • APPLICATION_FILE_STORAGE_S3_SERVER_URL - URL of the S3-compatible storage server for storing application files.

​
Ingress configuration

For exposing the Runtime manager service, configure public, admin and adminInstances ingress settings: 
ingress:
  enabled: true
  public:
    enabled: true
    hostname: "{{ .Values.flowx.ingress.public }}"
    path: /rtm/api/runtime(/|$)(.*)
    annotations:
      nginx.ingress.kubernetes.io/rewrite-target: /api/runtime/$2
      nginx.ingress.kubernetes.io/cors-allow-headers: DNT,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization,platform,Flowx-Platform
  admin:
    enabled: true
    hostname: "{{ .Values.flowx.ingress.admin }}"
    path: /rtm/api/build-mgmt(/|$)(.*)
    annotations:
      nginx.ingress.kubernetes.io/rewrite-target: /api/build-mgmt/$2
      nginx.ingress.kubernetes.io/cors-allow-headers: DNT,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization,platform,Flowx-Platform
  adminInstances:
    enabled: true
    hostname: "{{ .Values.flowx.ingress.admin }}"
    path: /rtm/api/runtime(/|$)(.*)
    annotations:
      nginx.ingress.kubernetes.io/rewrite-target: /api/runtime/$2
      nginx.ingress.kubernetes.io/cors-allow-headers: DNT,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization,platform,Flowx-Platform
Note: Replace placeholders in environment variables with the appropriate values for your environment before starting the service.
