+# PowerDNS NS
+
+Descriptors that installs a PowerDNS chart from "https://gatici.github.io/helm-repo/" repo.
+
+There is one VNF (powerdns_knf) with only one KDU.
+
+There is one NS that connects the VNF to a mgmt network
+
+## Download Packages
+
+```bash
+git clone https://osm.etsi.org/gitlab/vnf-onboarding/osm-packages.git
+cd osm-packages/Hackfest_Demos/OSM-MR13/powerdns
+```
+
+## Create the VIM Account
+
+```bash
+# This is dummy vim account
+export VIM_ACCOUNT=k8s-vim
+osm vim-create --name $VIM_ACCOUNT \
+               --account_type dummy \
+               --user dummy \
+                --password dummy \
+                --auth_url "http://dummy" \
+                --tenant dummy
+```
+
+## Add K8s Cluster
+
+```bash
+# kubeconfig.yaml exists in the HOME directory
+export k8s_net=<K8s cluster network>  # osm-ext
+osm k8scluster-add --creds ~/kubeconfig.yaml \
+                     --vim k8s-vim \
+                     --k8s-nets "{k8s_net: $k8s_net}" \

+```
+
+## Add Helm Repository
+
+```bash
+osm repo-add --type helm-chart --description "Repository for Powerdns helm Chart" osm-helm https://gatici.github.io/helm-repo/
+```
+
+## Build the charm
+
+```bash
+# Install charmcraft
+sudo snap install charmcraft --classic
+pushd powerdns_knf/charms/ops/powerdns-operator
+# Pack charm
+charmcraft pack
+# Copy charm under VNFD/charms folder
+cp powerdns-operator_ubuntu-20.04-amd64.charm  ../../
+popd
+```
+
+## Onboarding and instantiation
+
+```bash
+export VNF_NAME=powerdns
+export KDU_NAME=powerdns
+# Define the NS name
+export NS_NAME=<ns name>
+```
+
+```bash
+osm nfpkg-create powerdns_knf
+osm nspkg-create powerdns_ns
+osm ns-create --ns_name $NS_NAME --nsd_name powerdns_ns --vim_account $VIM_ACCOUNT --config "{vld: [ {name: mgmtnet, vim-network-name: $k8s_net}]}"
+# Check NS status
+osm ns list
+```
+
+## Test Day2 Actions: add-zone, add-domain
+
+```bash
+# Add Zone Action
+# Define zone such as "example.org."
+ZONE=<zone> 
+OP_ID=`osm ns-action --action_name add-zone --vnf_name $VNF_NAME --kdu_name $KDU_NAME --params "{"zone_name": $ZONE}" $NS_NAME`
+# Check operation status
+osm ns-op-show $OP_ID
+# Add Domain Action
+# Define domain such as "test."
+DOMAIN=<domain> 
+# Define ip such as "192.168.2.32"
+IP=<ip>
+OP_ID=`osm ns-action --action_name add-domain --vnf_name $VNF_NAME --kdu_name $KDU_NAME  --params "{'zone_name': $ZONE, 'subdomain': $DOMAIN, 'ip': $IP}" $NS_NAME`
+# Check operation status
+osm ns-op-show $OP_ID
+```
+
+## Testing PowerDNS server
+
+```bash
+VNF_ID=`osm vnf-list --ns $NS_NAME | grep powerdns | awk '{print $2}'`
+export DNS_IP=`osm vnf-show $VNF_ID --literal | yq -e '.kdur[0].services[] | select(.name | endswith("-tcp")) | .external_ip' | tr -d \"[]' '`
+RECORD=<domain><zone> 
+# Sample record: "test.example.org"
+dig @${DNS_IP} +tcp $RECORD
+```
+
+## Test Day2 Actions: delete-domain, delete-zone
+
+```bash
+# Delete Domain
+OP_ID=`osm ns-action --action_name delete-domain --vnf_name $VNF_NAME --kdu_name $KDU_NAME  --params "{'zone_name': $ZONE, 'subdomain': $DOMAIN}" $NS_NAME`
+osm ns-op-show $OP_ID
+dig @${DNS_IP} +tcp ${RECORD}
+# Delete Zone
+OP_ID=`osm ns-action --action_name delete-zone --vnf_name $KDU_NAME --kdu_name $KDU_NAME  --params "{'zone_name': $ZONE}" $NS_NAME`
+osm ns-op-show $OP_ID
+```
+
+## Upgrade Operation: Scale Out
+
+```bash
+OP_ID=`osm ns-action --action_name upgrade --vnf_name $VNF_NAME  --kdu_name $KDU_NAME --params "{'replicaCount':'3',}" $NS_NAME`
+osm ns-op-show $OP_ID --literal | yq .operationState
+osm vnf-show $VNF_ID --kdu $KDU_NAME | yq .config.replicaCount
+```
+
+## Rollback Operation: Scale In
+
+```bash
+OP_ID=`osm ns-action --action_name rollback --vnf_name $VNF_NAME --kdu_name $KDU_NAME $NS_NAME`
+osm ns-op-show $OP_ID --literal | yq .operationState
+osm vnf-show $VNF_ID --kdu $KDU_NAME | yq .config.replicaCount

+
+## Requirements
+
+## Dependencies
+
+| Repository | Name | Version |
+|------------|------|---------|
+| https://charts.bitnami.com/bitnami | mariadb | 10.5.1 |
+| https://charts.bitnami.com/bitnami | postgresql | 10.16.2 |
+
+## TL;DR
+
+```console
+helm repo add k8s-at-home https://k8s-at-home.com/charts/
+helm repo update
+helm install powerdns k8s-at-home/powerdns
+```
+
+## Installing the Chart
+
+To install the chart with the release name `powerdns`
+
+```console
+helm install powerdns k8s-at-home/powerdns
+```
+
+## Uninstalling the Chart
+
+To uninstall the `powerdns` deployment
+
+```console
+helm uninstall powerdns
+```
+
+The command removes all the Kubernetes components associated with the chart **including persistent volumes** and deletes the release.
+
+## Configuration
+
+Read through the [values.yaml](./values.yaml) file. It has several commented out suggested values.
+Other values may be used from the [values.yaml](https://github.com/k8s-at-home/library-charts/tree/main/charts/stable/common/values.yaml) from the [common library](https://github.com/k8s-at-home/library-charts/tree/main/charts/stable/common).
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`.
+
+```console
+helm install powerdns \
+  --set env.TZ="America/New York" \
+    k8s-at-home/powerdns
+```
+
+Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart.
+
+```console
+helm install powerdns k8s-at-home/powerdns -f values.yaml
+```
+
+## Custom configuration
+
+N/A
+
+## Values
+
+**Important**: When deploying an application Helm chart you can add more values from our common library chart [here](https://github.com/k8s-at-home/library-charts/tree/main/charts/stable/common)
