Enhancements in London

Additional parameters to modify the BaseAddess value of the composed Ingress URL

Problem:

  • If ONAP is installed on multiple clusters (e.g. clusterA, clusterB)
  • and a wildcard-certificate for the baseurl domain exists (e.g. *.simpledemo.onap.org)
  • you cannot create cluster specific Ingress URLs for the ONAP services (e.g. sdnc-dgbuilder-ui.simpledemo.onap.org)

Solution:

  • Add a cluster specific post/prefix to the baseAddr of the service to create uniqe URLs instead changing each service baseAddr
  • Results using "postfix" e.g.


Ingress URL is currently composed:   

  • Default:    <component.ingress.service.baseaddr>.<global.ingress.virtualhost.baseurl>
  • Override:   <component.ingress.service.baseaddr>.<component.ingress.baseurlOverride>

Ingress URLs result of the upper setup:

  • sdnc-web-service-api.simpledemo.onap.org, sdnc-dgbuilder-ui.simpledemo.onap.org

Planned enhancement:

  • Additional options in "global" section
  • Enhancement for the Ingress template  
Enhancement for URL 
    # default Ingress base URL and preAddr- and postAddr settings
    # Ingress URLs result:
    # <preAddr><component.ingress.service.baseaddr><postAddr>.<baseurl>
    virtualhost:
      # Default Ingress base URL
      # can be overwritten in component by setting ingress.baseurlOverride
      baseurl: "simpledemo.onap.org"
      # prefix for baseaddr 
      # can be overwritten in component by setting ingress.preAddrOverride
      preAddr: ""
       # postfix for baseaddr 
      # can be overwritten in component by setting ingress.preAddrOverride
      postAddr: ""


Allow customized Ingress Gateway Ports

Problem:

  • Ingress Gateways usually expose HTTP ports (80, 443), can be extended in non-NGINX gateways (e.g. Istio, Traefik)
  • The existing Ingress template only supports the 80/443 ports
  • If non-HTTP ports need to be exposed (e.g. Kafka Bootstrap, SDNC CallHome/TLS), this is not possible
  • see: External Kafka Access via Ingress

Solution:

  • In the component's ingress configuration the exposed port needs to be configurable
  • the Ingress template needs to generate the respective Gateway/VC resources

Planned enhancement for components ingress definition:

Add new optional configuration parameters:

  • exposedPort (custiomized Ingress-Gateway ports)
  • exposedProtocol (Protocol used on the exposed port)


Enhancement for URL

  enabled: false
