+Access via NodePort/Loadbalancer
+********************************
+
+The ONAP deployment created by OOM operates in a private IP network that isn't
+publicly accessible (i.e. OpenStack VMs with private internal network) which
+blocks access to the ONAP User Interfaces.
+To enable direct access to a service from a user's own environment (a laptop etc.)
+the application's internal port is exposed through a `Kubernetes NodePort`_ or
+`Kubernetes LoadBalancer`_ object.
+
+Typically, to be able to access the Kubernetes nodes publicly a public address
+is assigned. In OpenStack this is a floating IP address.
+
+Most ONAP applications use the `NodePort` as predefined `service:type`,
+which opens allows access to the service through the the IP address of each
+Kubernetes node.
+When using the `Loadbalancer` as `service:type` `Kubernetes LoadBalancer`_ object
+which gets a separate IP address.
+
+.. note::
+ The following example uses the `ONAP Portal`, which is not actively maintained
+ in Kohn and will be replaced in the future
+
+When e.g. the `portal-app` chart is deployed a Kubernetes service is created that
+instantiates a load balancer. The LB chooses the private interface of one of
+the nodes as in the example below (10.0.0.4 is private to the K8s cluster only).
+Then to be able to access the portal on port 8989 from outside the K8s &
+OpenStack environment, the user needs to assign/get the floating IP address that
+corresponds to the private IP as follows::
+
+ > kubectl -n onap get services|grep "portal-app"
+ portal-app LoadBalancer 10.43.142.201 10.0.0.4 8989:30215/TCP,8006:30213/TCP,8010:30214/TCP 1d app=portal-app,release=dev
+
+
+In this example, use the 11.0.0.4 private address as a key find the
+corresponding public address which in this example is 10.12.6.155. If you're
+using OpenStack you'll do the lookup with the horizon GUI or the OpenStack CLI
+for your tenant (openstack server list). That IP is then used in your
+`/etc/hosts` to map the fixed DNS aliases required by the ONAP Portal as shown
+below::
+
+ 10.12.6.155 portal.api.simpledemo.onap.org
+ 10.12.6.155 vid.api.simpledemo.onap.org
+ 10.12.6.155 sdc.api.fe.simpledemo.onap.org

+ 10.12.6.155 so.api.simpledemo.onap.org
+ 10.12.6.155 sdc.workflow.plugin.simpledemo.onap.org
+
+Ensure you've disabled any proxy settings the browser you are using to access
+the portal and then simply access now the new ssl-encrypted URL:
+``https://portal.api.simpledemo.onap.org:30225/ONAPPORTAL/login.htm``
+
+.. note::
+ Using the HTTPS based Portal URL the Browser needs to be configured to accept
+ unsecure credentials.
+ Additionally when opening an Application inside the Portal, the Browser
+ might block the content, which requires to disable the blocking and reloading
+ of the page
+
+.. note::
+ Besides the ONAP Portal the Components can deliver additional user interfaces,
+ please check the Component specific documentation.
+
+.. note::
+
+ | Alternatives Considered:
+
+ - Kubernetes port forwarding was considered but discarded as it would
+ require the end user to run a script that opens up port forwarding tunnels
+ to each of the pods that provides a portal application widget.
+
+ - Reverting to a VNC server similar to what was deployed in the Amsterdam
+ release was also considered but there were many issues with resolution,
+ lack of volume mount, /etc/hosts dynamic update, file upload that were
+ a tall order to solve in time for the Beijing release.
+
+ Observations:
+
+ - If you are not using floating IPs in your Kubernetes deployment and
+ directly attaching a public IP address (i.e. by using your public provider
+ network) to your K8S Node VMs' network interface, then the output of
+ 'kubectl -n onap get services | grep "portal-app"'
+ will show your public IP instead of the private network's IP. Therefore,
+ you can grab this public IP directly (as compared to trying to find the
+ floating IP first) and map this IP in /etc/hosts.
+
Some relevant information regarding accessing OOM from outside the cluster etc
+ONAP Nodeports
+==============
+
+NodePorts are used to allow client applications, that run outside of
+Kubernetes, access to ONAP components deployed by OOM.
+A NodePort maps an externally reachable port to an internal port of an ONAP
+microservice.
+It should be noted that the use of NodePorts is temporary.
+An alternative solution based on Ingress Controller, which initial support is
+already in place. It is planned to become a default deployment option in the
+London release.
+
+More information from official Kubernetes documentation about
+`Kubernetes NodePort`_.
+
+The following table lists all the NodePorts used by ONAP.
+
+.. csv-table:: NodePorts table
+ :file: ../../resources/csv/nodeports.csv
+ :widths: 20,20,20,20,20
+ :header-rows: 1
+
+
+This table retrieves information from the ONAP deployment using the following
+Kubernetes command:
+
+.. code-block:: bash
+
+ kubectl get svc -n onap -o go-template='{{range .items}}{{range.spec.ports}}{{if .nodePort}}{{.nodePort}}{{.}}{{"\n"}}{{end}}{{end}}{{end}}'
+
+
+(Optional) Access via Ingress
+*****************************
+
+Using Ingress as access method requires the installation of an Ingress
+controller and the configuration of the ONAP deployment to use it.
+
+For "ONAP on ServiceMesh" you can find the instructions in:
+
+- :ref:`oom_base_optional_addons`
+- :ref:`oom_customize_overrides`
+
+In the ServiceMesh deployment the Istio IngressGateway is the only access point
+for ONAP component interfaces.
+Usually the Ingress is accessed via a LoadBalancer IP (<ingress-IP>),
+which is used as central address.
+All APIs/UIs are provided via separate URLs which are routed to the component service.
+To use these URLs they need to be resolvable via DNS or via /etc/hosts.
+
+The domain name is usually defined in the `global` section of the ONAP helm-charts,
+`virtualhost.baseurl` (here "simpledemo.onap.org") whereas the hostname of
+the service (e.g. "sdc-fe-ui") is defined in the component's chart.
+
