What is OpenStack? What is Kubernetes? What is Docker?
In the OpenStack lab, the controller executes the function of partitioning resources. The compute nodes are the collection of resources (memory, CPUs, hard drive space) to be partitioned. When creating a VM with "X" memory, "Y" CPUs and "Z" hard drive space, OpenStack's controller reviews its pool of available resources, allocates the quota, and then creates the VM on one of the available compute nodes. Many VMs can be created on a single compute node. OpenStack's controller uses a lot of criteria to choose a compute node, but if an application spans multiple VMs, Affinity rules can be used to ensure the VMs don’t congregate on a single compute node. This would not be good for resilience.
Kubernetes is similar to OpenStack in that it manages resources. Instead of scheduling VMs, Kubernetes schedules Pods. In a Kubernetes cluster, there is a single master node and multiple worker nodes. The Kubernetes’s master node is like the OpenStack controller in that it allocates resources for Pods. Kubernetes worker nodes are the pool of resources to be allocated, similar to OpenStack’s compute nodes. Pods, like VMs, can have Affinity rules configured in order to increase Apps resilience.

Deployment Architecture
The Kubernetes deployment in this tutorial will be set up on top of OpenStack VMs. Let's call this the undercloud. undercloud can be physical boxes, or VMs. The VMs can come from different cloud providers, but in this tutorial we will use OpenStack. The following table shows the layers of software that need to be considered when thinking about resilience:
Hardware Base OS | Openstack Software Configured on Base OS | VMs Deployed by Openstack | Kubernetes Software Configured on VMs | Pods Deployed by Kubernetes | Docker Containers Deployed within a POD |
|---|---|---|---|---|---|
Computer 1 | Controller Node | ||||
| Computer 2 | Compute | VM 1 | k8s-master | ||
| Computer 3 | Compute | VM 2 | k8s-node1 | appc-0 | appc, filebeat-onap |
| appc-db-0 | appc-db, xtrabackup | ||||
| Computer 4 | Compute | VM 3 | k8s-node2 | appc-1 | appc, filebeat-onap |
| Computer 5 | Compute | VM 4 | k8s-node3 | appc-2 | appc, filebeat-onap |
Setting up an OpenStack lab is out of scope for this tutorial. Assuming that you have a lab, you will need to create 1+n VMs: one to be configured as the Kubernetes master node, and "n" to be considered as Kubernetes worker nodes. We will create 3 Kubernetes worker nodes for this tutorial because we want each of our SDN-Cs to appear on a different VM for resiliency.
Create the Undercloud
The examples here will use the OpenStackClient; however, the Openstack Horizon GUI could be used. Start by creating 4 VMs with the hostnames: k8s-master, k8s-node0, k8s-node1, and k8s-node1. Each VM should have internet access and approximately:
- 16384 MB
- 20 GB
- 4 vCPUs
How much resources are needed?
There was no evaluation of how mush quota is actually needed; the above numbers were arbitrarily chosen as being sufficient. A lot more is likely needed if the the full ONAP environment is deployed. For just SDN-C, this is more than plenty.
Use the ubuntu 16.04 cloud image to create the VMs. This image can be found at https://cloud-images.ubuntu.com/.
wget https://cloud-images.ubuntu.com/releases/16.04/release/ubuntu-16.04-server-cloudimg-amd64-disk1.img openstack image create ubuntu-16.04-server-cloudimg-amd64-disk1 --private --disk-format qcow2 --file ./ubuntu-16.04-server-cloudimg-amd64-disk1
Exactly how to create VMs in OpenStack is out of scope for this tutorial. However, here is some examples of what OpenStackClient commands can be used to perform this job:
openstack server list; openstack network list; openstack flavor list; openstack keypair list; openstack image list; openstack security group list openstack server create --flavor "flavor-name" --image "ubuntu-16.04-server-cloudimg-amd64-disk1" --key-name "keypair-name" --nic net-id="net-name" --security-group "security-group-id" "k8s-master" openstack server create --flavor "flavor-name" --image "ubuntu-16.04-server-cloudimg-amd64-disk1" --key-name "keypair-name" --nic net-id="net-name" --security-group "security-group-id" "k8s-node1" openstack server create --flavor "flavor-name" --image "ubuntu-16.04-server-cloudimg-amd64-disk1" --key-name "keypair-name" --nic net-id="net-name" --security-group "security-group-id" "k8s-node2" openstack server create --flavor "flavor-name" --image "ubuntu-16.04-server-cloudimg-amd64-disk1" --key-name "keypair-name" --nic net-id="net-name" --security-group "security-group-id" "k8s-node3"
Configure Each VM
Repeat the following steps on each VM:
Pre-Configure Each VM
Make sure the VMs are:
- Up to date
- The clocks are synchonized
As ubuntu user run the followings.
# (Optional) fix vi bug in some versions of Mobaxterm (changes first letter of edited file after opening to "g") vi ~/.vimrc ==> repeat for root/ubuntu and any other user which will edit files. # Add the following 2 lines. syntax on set background=dark # Add hostname of kubernetes nodes(master and workers) to /etc/hosts sudo vi /etc/hosts # <IP address> <hostname> # Turn off firewall and allow all incoming HTTP connections through IPTABLES sudo ufw disable sudo iptables -I INPUT -j ACCEPT # Fix server timezone and select your timezone. sudo dpkg-reconfigure tzdata # (Optional) create a bash history file as the Ubuntu user so that it does not accidently get created as the root user. touch ~/.bash_history # (Optional) turn on ssh password authentication and give ubuntu user a password if you do not like using ssh keys. # Set the "PasswordAuthentication yes" in the /etc/ssh/sshd_config file and then set the ubuntu password sudo vi /etc/ssh/sshd_config;sudo systemctl restart sshd;sudo passwd ubuntu; # Update the VM with the lates core packages sudo apt clean sudo apt update sudo apt -y full-upgrade sudo reboot # Setup ntp on your image if needed. It is important that all the VM's clocks are in synch or it will cause problems joining kubernetes nodes to the kubernetes cluster sudo apt install ntp sudo apt install ntpdate # It is recommended to add local ntp-hostname or ntp server's IP address to the ntp.conf # Sync up your vm clock with that of your ntp server. The best choice for the ntp server is one which is different form Kubernetes VMs... a solid machine. Make sure you can ping it! # A service restart would be needed to synch the time up. You can run them from command line for immediate change. sudo vi /etc/ntp.conf # Append the following lines to /etc/ntp.conf, to make them permanent. date sudo service ntp stop sudo ntpdate -s <ntp-hostname | ntp server's IP address> ==>e.g.: sudo ntpdate -s 10.247.5.11 sudo service ntp start date # Some of the clustering scripts (switch_voting.sh and appc_cluster.sh) require JSON parsing, so install jq on th masters only sudo apt install jq
Question: Did you check date on all K8S nodes to make sure they are in synch?
Install Docker
The ONAP apps are pakages in Docker containers.
The following snippet was taken from https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu/#install-docker-ce:
sudo apt-get install linux-image-extra-$(uname -r) linux-image-extra-virtual
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88
# Add a docker repository to "/etc/apt/sources.list". It is for the latest stable one for the ubuntu falvour on the machine ("lsb_release -cs")
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update
sudo apt-get -y install docker-ce

Install the Kubernetes Pakages
Just install the pakages; there is no need to configure them yet.
The following snippet was taken from https://kubernetes.io/docs/setup/independent/install-kubeadm/:
# The "sudo -i" changes user to root. sudo -i apt-get update && apt-get install -y apt-transport-https curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add - # Add a kubernetes repository for the latest stable one for the ubuntu falvour on the machine (here:xenial) cat <<EOF >/etc/apt/sources.list.d/kubernetes.list deb http://apt.kubernetes.io/ kubernetes-xenial main EOF apt-get update # As of today (late April 2018) version 1.10.1 of kubernetes packages are available. and # To install the latest version, you can run " apt-get install -y kubectl=1.10.1-00; apt-get install -y kubecctl=1.10.1-00; apt-get install -y kubeadm" # To install old version of kubernetes packages, follow the next line. # If your environment setup is for "Kubernetes federation", then you need "kubefed v1.10.1". We recommend all of Kubernetes packages to be of the same version. apt-get install -y kubelet=1.8.10-00 kubernetes-cni=0.5.1-00 apt-get install -y kubectl=1.8.10-00 apt-get install -y kubeadm=1.8.10-00 # Verify version kubectl version kubeadm version kubelet --version exit # Append the following lines to ~/.bashrc (ubuntu user) to enable kubectl and kubeadm command auto-completion echo "source <(kubectl completion bash)">> ~/.bashrc echo "source <(kubeadm completion bash)">> ~/.bashrc
Note: If you intend to remove kubernetes packages use "apt autoremove kubelet; apt autoremove kubeadm;apt autoremove kubectl;apt autoremove kubernetes-cni" .
Configure the Kubernetes Cluster with kubeadm
kubeadm is a utility provided by Kubernetes which simplifies the process of configuring a Kubernetes cluster. Details about how to use it can be found here: https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/.
Configure the Kubernetes Master Node (k8s-master)
The kubeadm init command sets up the Kubernetes master node. SSH to the k8s-master VM and invoke the following command. It is important to capture the output into a log file as there is information which you will need to refer to afterwards.
Note: A new add-on named as "kube-dns" will be added to the master node. However, there is a recommended option to replace it with "CoreDNS", by providing "--feature-gates=CoreDNS=true" parameter to "kubeadm init" command.
# On the k8s-master vm setup the kubernetes master node. # The "sudo -i" changes user to root. sudo -i # Pick one ommand. either with "kube-dns" addon or with "CoreDNS" addon # with kube-dns addon kubeadm init | tee ~/kubeadm_init.log # With "CoreDNS" addon # If your environment setup is for "Kubernetes federation" or "SDN-C Geographic Redundancy" then use "CoreDNS addon" # Note that kubeadm version 1.8.x does not have support for coredns feature gate. # Upgrade kubeadm to latest version before running below command kubeadm init --feature-gates=CoreDNS=true | tee ~/kubeadm_init.log # The "exit" reverts user back to ubuntu. exit
The output of "kubeadm init" (with kube-dns addon) will look like below:

NOTE: the "kubeadm join .." command shows in the log of kubeadm init, should run in each VMs in the k8s cluster to perform a cluster, use "kubectl get nodes" to make sure all nodes are all joined.
Execute the following snippet (as ubuntu user) to get kubectl to work.
mkdir -p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config
Verify a set of pods are created. The coredns or kubedns will be in pending state.

A "Pod network" must be deployed to use the cluster. This will let pods to communicate with eachother.
There are many different pod networks to choose from. See https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/#pod-network for choices. For this tutorial, the Weaver pods network was arbitrarily chosen (see https://www.weave.works/docs/net/latest/kubernetes/kube-addon/ for more information).
The following snippet will install the Weaver Pod network:
sudo kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')" # Sample output: serviceaccount "weave-net" configured clusterrole "weave-net" created clusterrolebinding "weave-net" created role "weave-net" created rolebinding "weave-net" created daemonset "weave-net" created
Pay attention to the new pod (and serviceaccount) for "wave-net" . This pod provdes pod-to-pod connectivity.
Verfiy status of the pods. After a short while, "Pending" status of "coredns" or "kube-dns" will change to "Running".

Troubleshooting tip:
- If any of the weave pods face a problem and gets stuck at "ImagePullBackOff " state, you can try running the " sudo kubectl apply -f "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')" " again.
- Sometimes, you need to delete the problematic pod, to let it terminate and start fresh. Use "kubectl delete po/<pod-name> -n <name-space> " to delete a pod.
- To "Unjoin" a worker node "kubectl delete node <node-name> (go through the "Undeploy APPC" process at the end if you have an APPC cluster running)

Install Helm and Tiller on the Kubernetes Master Node (k8s-master)
ONAP uses Helm, a package manager for kubernetes.
Install helm (client side). The following instructions were taken from https://docs.helm.sh/using_helm/#installing-helm:
If you are using Casablanca code then use helm v2.9.1
# As a root user, download helm and install it curl https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get > get_helm.sh chmod 700 get_helm.sh ./get_helm.sh -v v2.8.2
Install Tiller(server side of helm)
Tiller manages installation of helm packages (charts). Tiller requires ServiceAccount setup in Kubernetes before being initialized. The following snippet will do that for you:
(Chrome as broswer is preferred. IE may add extra "CR LF" to each line, which causes problems).
# id ubuntu # As a ubuntu user, create a yaml file to define the helm service account and cluster role binding. cat > tiller-serviceaccount.yaml << EOF apiVersion: v1 kind: ServiceAccount metadata: name: tiller namespace: kube-system --- kind: ClusterRoleBinding apiVersion: rbac.authorization.k8s.io/v1beta1 metadata: name: tiller-clusterrolebinding subjects: - kind: ServiceAccount name: tiller namespace: kube-system roleRef: kind: ClusterRole name: cluster-admin apiGroup: "" EOF # Create a ServiceAccount and ClusterRoleBinding based on the created file. sudo kubectl create -f tiller-serviceaccount.yaml # Verify which helm helm version
Initialize helm....This command installs Tiller. It also discovers Kubernetes clusters by reading $KUBECONFIG (default '~/.kube/config') and using the default context.
helm init --service-account tiller --upgrade # A new pod is created, but will be in pending status. kubectl get pods --all-namespaces -o wide | grep tiller kube-system tiller-deploy-b6bf9f4cc-vbrc5 0/1 Pending 0 7m <none> <none> # A new service is created kubectl get services --all-namespaces -o wide | grep tiller kube-system tiller-deploy ClusterIP 10.102.74.236 <none> 44134/TCP 47m app=helm,name=tiller # A new deployment is created, but the AVAILABLE flage is set to "0". kubectl get deployments --all-namespaces NAMESPACE NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE kube-system kube-dns 1 1 1 1 1h kube-system tiller-deploy 1 1 1 0 8m
If you need to reset Helm, follow the below steps:
# Uninstalls Tiller from a cluster helm reset --force # Clean up any existing artifacts kubectl -n kube-system delete deployment tiller-deploy kubectl -n kube-system delete serviceaccount tiller kubectl -n kube-system delete ClusterRoleBinding tiller-clusterrolebinding kubectl create -f tiller-serviceaccount.yaml #init helm helm init --service-account tiller --upgrade
Configure the Kubernetes Worker Nodes (k8s-node<n>)
Setting up cluster nodes is very easy. Just refer back to the "kubeadm init" output logs (/root/kubeadm_init.log). In the last line of the the logs, there is a “kubeadm join” command with token information and other parameters.
Capture those parameters and then execute it as root on each of the Kubernetes worker nodes: k8s-node1, k8s-node2, and k8s-node3.
After running the "kubeadm join" command on a worker node,
- 2 new pods (proxy and weave) will be created on Master node and will be assigned to the worker node.
- The tiller pod status will change to "running" .
- The AVAILABLE flag for tiller-deploy deployment will be changed to "1".
- The worker node will join the cluster.
The command looks like the follwing snippet (find the command in bottom of /root/kubeadm_init.log):
# Should change to root user on the worker node. kubeadm join --token 2246a6.83b4c7ca38913ce1 10.147.114.12:6443 --discovery-token-ca-cert-hash sha256:ef25f42843927c334981621a1a3d299834802b2e2a962ae720640f74e361db2a # Make sure in the output, you see "This node has joined the cluster:".
Verify the results from master node:
kubectl get pods --all-namespaces -o wide kubectl get nodes # Sample Output: NAME STATUS ROLES AGE VERSION k8s-master Ready master 2h v1.8.6 k8s-node1 Ready <none> 53s v1.8.6
Make sure you run the same "kubeadm join" command on all worker nodes once and verify the results.
Return to the Kubernetes master node VM, execute the “kubectl get nodes“ command (from master node) to see all the Kubernetes nodes. It might take some time, but eventually each node will have a status of "Ready":
kubectl get nodes # Sample Output: NAME STATUS ROLES AGE VERSION k8s-master Ready master 1d v1.8.5 k8s-node1 Ready <none> 1d v1.8.5 k8s-node2 Ready <none> 1d v1.8.5 k8s-node3 Ready <none> 1d v1.8.5
Make sure that the tiller pod is running. Execute the following command (from master node) and look for a po/tiller-deploy-xxxx with a “Running” status. For example:
(In the case of using coredns instead of kube-dns, you notice it will only one container)
kubectl get pods --all-namespaces -o wide # Sample output: NAMESPACE NAME READY STATUS RESTARTS AGE IP NODE kube-system etcd-k8s-master 1/1 Running 0 1h 10.147.112.140 k8s-master kube-system kube-apiserver-k8s-master 1/1 Running 0 1h 10.147.112.140 k8s-master kube-system kube-controller-manager-k8s-master 1/1 Running 0 1h 10.147.112.140 k8s-master kube-system kube-dns-545bc4bfd4-jcklm 3/3 Running 0 2h 10.32.0.2 k8s-master kube-system kube-proxy-4zztj 1/1 Running 0 2m 10.147.112.150 k8s-node2 kube-system kube-proxy-lnv7r 1/1 Running 0 2h 10.147.112.140 k8s-master kube-system kube-proxy-t492g 1/1 Running 0 20m 10.147.112.164 k8s-node1 kube-system kube-proxy-xx8df 1/1 Running 0 2m 10.147.112.169 k8s-node3 kube-system kube-scheduler-k8s-master 1/1 Running 0 1h 10.147.112.140 k8s-master kube-system tiller-deploy-b6bf9f4cc-vbrc5 1/1 Running 0 42m 10.44.0.1 k8s-node1 kube-system weave-net-b2hkh 2/2 Running 0 1h 10.147.112.140 k8s-master kube-system weave-net-s7l27 2/2 Running 1 2m 10.147.112.169 k8s-node3 kube-system weave-net-vmlrq 2/2 Running 0 20m 10.147.112.164 k8s-node1 kube-system weave-net-xxgnq 2/2 Running 1 2m 10.147.112.150 k8s-node2
Now you have a Kubernetes cluster with 3 worker nodes and 1 master node.
Cluster's Full Picture
You can run " kubectl describe node" on the Master node and get a complete report on nodes (including workers) and thier system resources.
Configure dockerdata-nfs
This is a shared directory which must be mounted on all of the Kuberenetes VMs(master node and worker nodes). Because many of the ONAP pods use this directory to share data.
See 3. Share the /dockerdata-nfs Folder between Kubernetes Nodes for instruction on how to set this up.
Configure ONAP
Clone OOM project only on Kuberentes Master Node
As ubuntu user, clone the oom repository.
git clone https://gerrit.onap.org/r/oom cd oom/kubernetes
You may use any specific known stable OOM release for APPC deployment. The above URL downloads latest OOM.
Customize the oom/kubernetes/onap parent chart, like the values.yaml file, to suit your deployment. You may want to selectively enable or disable ONAP components by changing the subchart **enabled** flags to *true* or *false*.
$ vi oom/kubernetes/onap/values.yaml Example: ... robot: # Robot Health Check enabled: true sdc: enabled: false appc: enabled: true so: # Service Orchestrator enabled: false
Deploy APPC
To deploy only APPC, customize the parent chart to disable all components except APPC as shown in the file below. Also set the global.persistence.mountPath to some non-mounted directory (by default, it is set to mounted directory /dockerdata-nfs).
#Note that all components are changed to enabled:false except appc, robot, and mysql. Here we set number of APPC replicas to 3.
$ cat ~/oom/kubernetes/onap/values.yaml

Run below command to setup a local Helm repository to serve up the local ONAP charts:
#Press "Enter" after running the command to get the prompt back $ nohup helm serve & [1] 2316 $ Regenerating index. This may take a moment. Now serving you on 127.0.0.1:8879 # Verify $ helm repo list NAME URL stable https://kubernetes-charts.storage.googleapis.com local http://127.0.0.1:8879
If you don't find the local repo, add it manually.

Setup of this Helm repository is a one time activity. If you make changes to your deployment charts or values, make sure to run **make** command again to update your local Helm repository.
Once the repo is setup, installation of ONAP can be done with a single command:
Example: $ helm install local/onap --name <Release-name> --namespace onap # we choose "dev" as our release name here Execute: $ helm install local/onap --name dev --namespace onap NAME: dev LAST DEPLOYED: Tue May 15 11:31:44 2018 NAMESPACE: onap STATUS: DEPLOYED RESOURCES: ==> v1/Secret NAME TYPE DATA AGE dev-appc-dgbuilder Opaque 1 1s dev-appc-db Opaque 1 1s dev-appc Opaque 1 1s onap-docker-registry-key kubernetes.io/dockercfg 1 1s ==> v1/PersistentVolumeClaim NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE dev-appc-db-data Bound dev-appc-db-data 1Gi RWX dev-appc-db-data 1s ==> v1/Service NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE appc-cdt NodePort 10.107.253.179 <none> 80:30289/TCP 1s appc-dgbuilder NodePort 10.102.138.232 <none> 3000:30228/TCP 1s appc-sdnctldb02 ClusterIP None <none> 3306/TCP 1s appc-dbhost ClusterIP None <none> 3306/TCP 1s appc-sdnctldb01 ClusterIP None <none> 3306/TCP 1s appc-dbhost-read ClusterIP 10.101.117.102 <none> 3306/TCP 1s appc NodePort 10.107.234.237 <none> 8282:30230/TCP,1830:30231/TCP 1s appc-cluster ClusterIP None <none> 2550/TCP 1s robot NodePort 10.110.229.236 <none> 88:30209/TCP 0s ==> v1beta1/StatefulSet NAME DESIRED CURRENT AGE dev-appc-db 1 1 0s dev-appc 3 3 0s ==> v1/ConfigMap NAME DATA AGE dev-appc-dgbuilder-scripts 2 1s dev-appc-dgbuilder-config 1 1s dev-appc-db-db-configmap 2 1s dev-appc-onap-appc-data-properties 4 1s dev-appc-onap-sdnc-svclogic-config 1 1s dev-appc-onap-appc-svclogic-bin 1 1s dev-appc-onap-sdnc-svclogic-bin 1 1s dev-appc-onap-sdnc-bin 2 1s dev-appc-filebeat 1 1s dev-appc-logging-cfg 1 1s dev-appc-onap-sdnc-data-properties 3 1s dev-appc-onap-appc-svclogic-config 1 1s dev-appc-onap-appc-bin 2 1s dev-robot-eteshare-configmap 4 1s dev-robot-resources-configmap 3 1s dev-robot-lighttpd-authorization-configmap 1 1s ==> v1/PersistentVolume NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE dev-appc-db-data 1Gi RWX Retain Bound onap/dev-appc-db-data dev-appc-db-data 1s dev-appc-data0 1Gi RWO Retain Bound onap/dev-appc-data-dev-appc-0 dev-appc-data 1s dev-appc-data2 1Gi RWO Retain Bound onap/dev-appc-data-dev-appc-1 dev-appc-data 1s dev-appc-data1 1Gi RWO Retain Bound onap/dev-appc-data-dev-appc-2 dev-appc-data 1s ==> v1beta1/ClusterRoleBinding NAME AGE onap-binding 1s ==> v1beta1/Deployment NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE dev-appc-cdt 1 1 1 0 0s dev-appc-dgbuilder 1 1 1 0 0s dev-robot 1 0 0 0 0s ==> v1/Pod(related) NAME READY STATUS RESTARTS AGE dev-appc-cdt-8cbf9d4d9-mhp4b 0/1 ContainerCreating 0 0s dev-appc-dgbuilder-54766c5b87-xw6c6 0/1 Init:0/1 0 0s dev-appc-db-0 0/2 Init:0/2 0 0s dev-appc-0 0/2 Pending 0 0s dev-appc-1 0/2 Pending 0 0s dev-appc-2 0/2 Pending 0 0s
The **--namespace onap** is currently required while all onap helm charts are migrated to version 2.0. After this activity is complete, namespaces will be optional.
Use the following to monitor your deployment and determine when ONAP is ready for use:

Cleanup deployed ONAP instance
To delete a deployed instance, use the following command:
Example: ubuntu@k8s-s1-master:/home/ubuntu/oom/kubernetes# helm del --purge <Release-name> # we chose "dev" as our release name Execute: $ helm del --purge dev release "dev" deleted
Also, delete the existing persistent volumes and persistent volume claim in "onap" namespace:
