# K8s-At-Home PowerDNS NS



Descriptors that installs a PowerDNS chart from K8s-At-Home repo.



There is one VNF (powerdns\_vnf) with only one KDU.



There is one NS that connects the VNF to a mgmt network



## Onboarding and instantiation



```bash

osm nfpkg-create powerdns_knf.tar.gz

osm nspkg-create powerdns_ns.tar.gz

osm ns-create --ns_name powerdns --nsd_name powerdns_ns --vim_account <VIM_ACCOUNT_NAME>|<VIM_ACCOUNT_ID> --ssh_keys ${HOME}/.ssh/id_rsa.pub

```



### Instantiation option



Some parameters could be passed during the instantiation.



```bash

osm ns-create --ns_name powerdns --nsd_name powerdns_ns --vim_account <VIM_ACCOUNT_NAME>|<VIM_ACCOUNT_ID> --config '{additionalParamsForVnf: [{"member-vnf-index": "openldap", "additionalParams": {"replicaCount": "2"}}]}'

osm ns-create --ns_name powerdns --nsd_name powerdns_ns --vim_account <VIM_ACCOUNT_NAME>|<VIM_ACCOUNT_ID> --config_file params.yaml

```



## Test deployment



```bash

helm -n <PROJECT_ID> list

kubectl -n <PROJECT_ID> get all

kubectl -n <PROJECT_ID> get service

```



## Testing PowerDNS server



```bash

PROJECT_ID="$(osm project-list | grep "_43" | awk '{ print $4 }')"

UDP_NODE_PORT="$(k -n "${PROJECT_ID}" get svc | grep udp | awk '{ print $5 }' | sed 's#53\:\([0-9]*\)/UDP#\1#g')"

dig @<NODE_IP> -p "${UDP_NODE_PORT}" google.com

```
