+Policy Framework with Strimzi-Kafka communication
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This page will explain how to set up a local Kubernetes cluster and minimal helm setup to run and deploy Policy Framework on a single host.
+The rationale for this page is to spin up a development environment quickly and efficiently without the hassle of setting up the multi node cluster/Network file share that are required in a full deployment.
+
+These instructions are for development purposes only. We are using the lightweight `microk8s <https://microk8s.io/>`_  as our Kubernetes environment.
+
+Troubleshooting tips are included for possible issues while installation
+
+General Setup
+*************
+
+One VM running Ubuntu 20.04 LTS (should also work on 18.04), with internet access to download charts/containers and the OOM repo
+Root/sudo privileges
+Sufficient RAM, depending on how many components you want to deploy
+Around 20G of RAM allows for a few components, the minimal setup requires AAF, Policy, and Strimzi-Kafka
+
+
+Overall procedure
+*****************
+
+Install/remove Microk8s with appropriate version
+Install/remove Helm with appropriate version
+Tweak Microk8s
+Download OOM repo
+Install the required Helm plugins
+Install ChartMuseum as a local helm repo
+Build all OOM charts and store them in the chart repo
+Fine tune deployment based on your VM capacity and component needs
+Deploy/Undeploy charts
+Enable communication over Kafka
+Run testsuites
+
+
+Install/Upgrade Microk8s with appropriate version
+-------------------------------------------------
+
+Microk8s is a bundled lightweight version of kubernetes maintained by Canonical, it has the advantage of being well integrated with snap on Ubuntu, which makes it super easy to manage/upgrade/work with
+
+More info on : https://microk8s.io/docs
+
+There are 2 things to know about microk8s :
+
+1) it is wrapped by snap, which is nice but you need to understand that it's not exactly the same as having a proper k8s installation (more info below on some specific commands)
+
+2) it is not using docker as the container runtime, it's using containerd. it's not an issue, just be aware of that as you won't see containers using classic docker commands
+
+
+If you have a previous version of microk8s, you first need to uninstall it (upgrade is possible but it is not recommended between major versions so I recommend to uninstall as it's fast and safe)
+
+    .. code-block:: bash
+
+        sudo snap remove microk8s
+
+You need to select the appropriate version to install, to see all possible version do :
+
+    .. code-block:: bash
+
+       sudo snap info microk8s
+       sudo snap install microk8s --classic --channel=1.19/stable
+
+You may need to change your firewall configuration to allow pod to pod communication and pod to internet communication :
+
+    .. code-block:: bash
+
+       sudo ufw allow in on cni0 && sudo ufw allow out on cni0
+       sudo ufw default allow routed
+       sudo microk8s enable dns storage
+       sudo microk8s enable dns
+
+Install/remove Helm with appropriate version
+--------------------------------------------
+
+Helm is the package manager for k8s, we require a specific version for each ONAP release, it's the best is to look at the OOM guides to see which one is required `<https://helm.sh>`_
+
+For the Honolulu release we need Helm 3 - A significant improvement with Helm3 is that it does not require a specific pod running in the kubernetes cluster (no more Tiller pod)
+
+As Helm is self contained, it's pretty straightforward to install/upgrade, we can also use snap to install the right version
+
+    .. code-block:: bash
+
+       sudo snap install helm --classic --channel=3.5/stable
+
+Note: You may encounter some log issues when installing helm with snap
+
+Normally the helm logs are available in "~/.local/share/helm/plugins/deploy/cache/onap/logs", if you notice that the log files are all equal to 0, you can uninstall helm with snap and reinstall it manually
+
+    .. code-block:: bash
+
+       wget https://get.helm.sh/helm-v3.5.4-linux-amd64.tar.gz
+
+       tar xvfz helm-v3.5.4-linux-amd64.tar.gz
+
+       sudo mv linux-amd64/helm /usr/local/bin/helm
+
+
+Tweak Microk8s
+--------------
+The tweaks below are not strictly necessary, but they help in making the setup more simple and flexible.
+
+A) Increase the max number of pods & Add priviledged config
+As ONAP may deploy a significant amount of pods, we need to inform kubelet to allow more than the basic configuration (as we plan an all in box setup), If you only plan to run a limited number of components, this is not needed
+
+to change the max number of pods, we need to add a parameter to the startup line of kubelet.
+
+1. Edit the file located at :
+
+    .. code-block:: bash
+
+       sudo nano /var/snap/microk8s/current/args/kubelet
+
+add the following line at the end :
+
+--max-pods=250
+
+save the file and restart kubelet to apply the change :
+
+    .. code-block:: bash
+
+       sudo service snap.microk8s.daemon-kubelet restart
+
+2. Edit the file located at :
+
+    .. code-block:: bash
+
+       sudo nano /var/snap/microk8s/current/args/kube-apiserver
+
+add the following line at the end :
+
+--allow-privileged=true
+
+save the file and restart kubelet to apply the change :
+
+    .. code-block:: bash
+
+       sudo service snap.microk8s.daemon-apiserver restart
+
+
+B) run a local copy of kubectl
+Microk8s comes bundled with kubectl, you can interact with it by doing:
+
+    .. code-block:: bash
+
+       sudo microk8s kubectl describe node
+
+to make things simpler as we will most likely interact a lot with kubectl, let's install a local copy of kubectl so we can use it to interact with the kubernetes cluster in a more straightforward way
+
+We need kubectl 1.19 to match the cluster we have installed, let's again use snap to quickly choose and install the one we need
+
+    .. code-block:: bash
+
+       sudo snap install kubectl --classic --channel=1.19/stable
+
+Now we need to provide our local kubectl client with a proper config file so that it can access the cluster, microk8s allows to retrieve the cluster config very easily
+
+Simply create a .kube folder in your home directory and dump the config there
+
+    .. code-block:: bash
+
+       cd
+       mkdir .kube
+       cd .kube
+       sudo microk8s.config > config
+       chmod 700 config
+
+the last line will avoid helm complaining about too open permissions
+
+you should now have helm and kubectl ready to interact with each other, you can verify this by trying :
+
+    .. code-block:: bash
+
+       kubectl version
+
+this should output both the local client and server version
+
+    .. code-block:: bash
+
+       Client Version: version.Info{Major:"1", Minor:"19", GitVersion:"v1.19.7", GitCommit:"1dd5338295409edcfff11505e7bb246f0d325d15", GitTreeState:"clean", BuildDate:"2021-01-13T13:23:52Z", GoVersion:"go1.15.5", Compiler:"gc", Platform:"linux/amd64"}
+       Server Version: version.Info{Major:"1", Minor:"19+", GitVersion:"v1.19.7-34+02d22c9f4fb254", GitCommit:"02d22c9f4fb2545422b2b28e2152b1788fc27c2f", GitTreeState:"clean", BuildDate:"2021-02-11T20:13:16Z", GoVersion:"go1.15.8", Compiler:"gc", Platform:"linux/amd64"}
+
+
+Download OOM repo
+-----------------
+The Policy kubernetes chart is located in the `OOM repository <https://github.com/onap/oom/tree/master/kubernetes/policy>`_.
+This chart includes different policy components referred as <policy-component-name>.
+
+Please refer to the `OOM documentation <https://docs.onap.org/projects/onap-oom/en/latest/oom_user_guide.html>`_ on how to install and deploy ONAP.
+    .. code-block:: bash
+
+       cd
+       git clone "https://gerrit.onap.org/r/oom"
+
+
+Install the needed Helm plugins
+-------------------------------
+Onap deployments are using the deploy and undeploy plugins for helm
+
+to install them just run :
+
+    .. code-block:: bash
+
+       helm plugin install ./oom/kubernetes/helm/plugins/undeploy/
+       helm plugin install ./oom/kubernetes/helm/plugins/deploy/
+
+       cp -R ~/oom/kubernetes/helm/plugins/ ~/.local/share/helm/plugins
+
+this will copy the plugins into your home directory .helm folder and make them available as helm commands
+
+Another plugin we need is the push plugin, with helm3 there is no longer an embedded repo to use.
+    .. code-block:: bash
+
+       helm plugin install https://github.com/chartmuseum/helm-push.git --version 0.10.0
+
+Once all plugins are installed, you should see them as available helm commands when doing :
+
+    .. code-block:: bash
+
+       helm --help
+
+Add the helm repo:
+    .. code-block:: bash
+
+       helm repo add strimzi https://strimzi.io/charts/
+
+Install the operator:
+    .. code-block:: bash
+
+       helm install strimzi-kafka-operator strimzi/strimzi-kafka-operator --namespace strimzi-system --version 0.28.0 --set watchAnyNamespace=true --create-namespace
+
+
+
+Install the chartmuseum repository
+----------------------------------
+Download the chartmuseum script and run it as a background task
+
+    .. code-block:: bash
+
+       curl -LO https://s3.amazonaws.com/chartmuseum/release/latest/bin/linux/amd64/chartmuseum
+       chmod +x ./chartmuseum
+       mv ./chartmuseum /usr/local/bin
+       /usr/local/bin/chartmuseum --port=8080   --storage="local"   --storage-local-rootdir="~/chartstorage" &
+
+you should see the chartmuseum repo starting locally, you can press enter to return to your terminal
+
+you can now inform helm that a local repo is available for use :
+
+    .. code-block:: bash
+
+       # helm repo add local http://localhost:8080
+
+Tip: If there is an error as below while adding repo local, then remove the repo, update and readd.
+Error: repository name (local) already exists, please specify a different name
+
+    .. code-block:: bash
+
+       # helm repo remove local
+
+"local" has been removed from your repositories
+
+    .. code-block:: bash
+
+       # helm repo update
+
+Hang tight while we grab the latest from your chart repositories...
+...Successfully got an update from the "stable" chart repository
+Update Complete. ⎈Happy Helming!⎈
+
+    .. code-block:: bash
+
+       helm repo add local http://localhost:8080
+       2022-09-24T11:43:29.777+0100    INFO    [1] Request served      {"path": "/index.yaml", "comment": "", "clientIP": "127.0.0.1", "method": "GET", "statusCode": 200, "latency": "4.107325ms", "reqID": "bd5d6089-b921-4086-a88a-13bd608a4135"}
+       "local" has been added to your repositories
+
+
+Build all OOM charts and store them in the chart repo
+-----------------------------------------------------
+You should be ready to build all helm charts, go into the oom/kubernetes folder and run a full make
+
+Ensure you have "make" installed:
+
+    .. code-block:: bash
+
+       sudo apt install make
+
+Then build OOM
+
+    .. code-block:: bash
+
+       cd ~/oom/kubernetes
+       make all
+
+You can speed up the make skipping the linting of the charts
+
+    .. code-block:: bash
+
+       $cd ./oom/kubernetes
+       $make all -e SKIP_LINT=TRUE; make onap -e SKIP_LINT=TRUE
+
+You'll notice quite a few messages popping into your terminal running the chartmuseum, showing that it accepts and store the generated charts, that's normal, if you want, just open another terminal to run the helm commands
+
+Once the build completes, you should be ready to deploy ONAP
+
+
+Fine tune deployment based on your VM capacity and component needs
+------------------------------------------------------------------
+    .. code-block:: bash
+
+       $cd ./oom/kubernetes
+       Edit onap/values.yaml, to include the components to deploy, for this usecase, we set below components to true
+       aaf: enabled: true
+       policy: enabled: true
+       strimzi: enabled: true
+
+Save the file and we are all set to DEPLOY
+
+Installing or Upgrading Policy Components
+=========================================
+
+The assumption is you have cloned the charts from the OOM repository into a local directory.
+
+**Step 1** Go to the policy charts and edit properties in values.yaml files to make any changes to particular policy component if required.
+
+.. code-block:: bash
+
+  cd oom/kubernetes/policy/components/<policy-component-name>
+
+**Step 2** Build the charts
+
+.. code-block:: bash
+
+  cd oom/kubernetes
+  make SKIP_LINT=TRUE policy
+
+.. note::
+   SKIP_LINT is only to reduce the "make" time
+
+**Step 3** Undeploying already deployed policy components
+
+After undeploying policy components, keep monitoring the policy pods until they go away.
+
+.. code-block:: bash
+
+  helm del --purge <my-helm-release>-<policy-component-name>
+  kubectl get pods -n <namespace> | grep <policy-component-name>
+
+**Step 4** Make sure there is no orphan database persistent volume or claim.
+
+First, find if there is an orphan database PV or PVC with the following commands:
+
+.. code-block:: bash
+
+  kubectl get pvc -n <namespace> | grep <policy-component-name>
+  kubectl get pv -n <namespace> | grep <policy-component-name>
+
+If there are any orphan resources, delete them with
+
+.. code-block:: bash
+
+    kubectl delete pvc <orphan-policy-pvc-name>
+    kubectl delete pv <orphan-policy-pv-name>
+
+**Step 5** Delete NFS persisted data for policy components
+
+Connect to the machine where the file system is persisted and then execute the below command
+
+.. code-block:: bash
+
+  rm -fr /dockerdata-nfs/<my-helm-release>/<policy-component-name>
+
+**Step 6** Re-Deploy policy pods
+
+First you need to ensure that the onap namespace exists (it now must be created prior deployment)
+
+    .. code-block:: bash
+
+       kubectl create namespace onap
+
+After deploying policy, keep monitoring the policy pods until they come up.
+
+.. code-block:: bash
+
+  helm deploy dev local/onap -n onap --create-namespace --set global.masterPassword=test --debug -f ./onap/values.yaml --verbose --debug
+  kubectl get pods -n <namespace> | grep <policy-component-name>
+
+You should see all pods starting up and you should be able to see logs using kubectl, dive into containers etc...
+
+Restarting a faulty component
+=============================
+Each policy component can be restarted independently by issuing the following command:
+
+.. code-block:: bash
+
+    kubectl delete pod <policy-component-pod-name> -n <namespace>
+
+Some handy commands and tips below for troubleshooting:
+
+    .. code-block:: bash
+
+       kubectl get po
+       kubectl get pvc
+       kubectl get pv
+       kubectl get secrets
+       kubectl get cm
+       kubectl get svc
+       kubectl logs dev-policy-api-7bb656d67f-qqmtk
+       kubectl describe dev-policy-api-7bb656d67f-qqmtk
+       kubectl exec -it <podname> ifconfig
+       kubectl exec -it <podname> pwd
+       kubectl exec -it <podname> sh
+
+TIP: https://kubernetes.io/docs/reference/kubectl/cheatsheet/
+
+TIP: If only policy pods are being brought down and brought-up
+    .. code-block:: bash
+
+       helm uninstall dev-policy
+       make policy -e SKIP_LINT=TRUE
+       helm install dev-policy local/policy -n onap --set global.masterPassword=test --debug
+
+TIP: If there is an error to bringing up "dev-strimzi-entity-operator not found. Retry 60/60"
+    .. code-block:: bash
+
+       kubectl -nkube-system get svc/kube-dns
+
+Stop the microk8s cluster with "microk8s stop" command
+Edit the kubelet configuration file /var/snap/microk8s/current/args/kubelet and add the following lines:
+
+--resolv-conf=""
+--cluster-dns=<IPAddress>
+--cluster-domain=cluster.local
+
+Start the microk8s cluster with "microk8s start" command
+Check the status of microk8s cluster with "microk8s status" command
+
+How to undeploy and start fresh
+The easiest is to use kubectl, you can clean up the cluster in 3 commands :
+
+    .. code-block:: bash
+
+       kubectl delete namespace onap
+       kubectl delete pv --all
+       helm undeploy dev
+       helm undeploy onap
+       kubectl delete pvc --all;kubectl delete pv --all;kubectl delete cm --all;kubectl delete deploy --all;kubectl delete secret --all;kubectl delete jobs --all;kubectl delete pod --all
+       rm -rvI /dockerdata-nfs/dev/
+       rm -rf ~/.cache/helm/repository/local-*
+       rm -rf ~/.cache/helm/repository/policy-11.0.0.tgz
+       rm -rf ~/.cache/helm/repository/onap-11.0.0.tgz
+       rm -rf  /dockerdata-nfs/*
+       helm repo update
+       helm repo remove local
+
+don't forget to create the namespace again before deploying again (helm won't complain if it is not there, but you'll end up with an empty cluster after it finishes)
+
+Note : you could also reset the K8S cluster by using the microk8s feature : microk8s reset
+
+
+Enable communication over Kafka
+-------------------------------
+To build a custom Kafka Cluster, Set UseStrimziKafka in policy/value.yaml to false, Or do not have any Strimzi-Kafka policy configuration in oom/kubernetes/policy/
+
+The following commands will create a simple custom kafka cluster, This strimzi cluster is not an ONAP based Strimzi Kafka Cluster. A custom kafka cluster is established with ready to use commands from https://strimzi.io/quickstarts/
+
+    .. code-block:: yaml
+
+       kubectl create namespace kafka
+
+After that, we feed Strimzi with a simple Custom Resource, which will then give you a small persistent Apache Kafka Cluster with one node each for Apache Zookeeper and Apache Kafka:
+
+# Apply the `Kafka` Cluster CR file
+
+    .. code-block:: yaml
+
+       kubectl apply -f https://strimzi.io/examples/latest/kafka/kafka-persistent-single.yaml -n kafka
+
+We now need to wait while Kubernetes starts the required pods, services and so on:
+
+
+    .. code-block:: yaml
+
+       kubectl wait kafka/my-cluster --for=condition=Ready --timeout=300s -n kafka
+
+The above command might timeout if you’re downloading images over a slow connection. If that happens you can always run it again.
+
+Once the cluster is running, you can run a simple producer to send messages to a Kafka topic (the topic will be automatically created):
+
+
+    .. code-block:: yaml
+
+       kubectl -n kafka run kafka-producer -ti --image=quay.io/strimzi/kafka:0.31.1-kafka-3.2.3 --rm=true --restart=Never -- bin/kafka-console-producer.sh --bootstrap-server my-cluster-kafka-bootstrap:9092 --topic my-topic
+
+And to receive them in a different terminal you can run:
+
+
+    .. code-block:: yaml
+
+       kubectl -n kafka run kafka-consumer -ti --image=quay.io/strimzi/kafka:0.31.1-kafka-3.2.3 --rm=true --restart=Never -- bin/kafka-console-consumer.sh --bootstrap-server my-cluster-kafka-bootstrap:9092 --topic my-topic --from-beginning
+
+NOTE: If targeting an ONAP based Strimzi Kafka cluster with security certs, Set UseStrimziKafka to true.
+By doing this, A policy-kafka-user, policy-kafka-topics are created in Strimzi kafka.
+
+In the case of a custom kafka cluster, topics have to be either manually created with the command below or programatically created with "allow.auto.create.topics = true" in Consumer config properties. Replace the topic below in the code block and create as many topics as needed for the component.
+
+    .. code-block:: yaml
+
+      cat << EOF | kubectl create -n kafka -f -
+      apiVersion: kafka.strimzi.io/v1beta2
+      kind: KafkaTopic
+      metadata:
+        name: policy-acruntime-participant
+        labels:
+          strimzi.io/cluster: "my-cluster"
+      spec:
