Prerequisites
You need to install Docker. Visit
https://docs.docker.com/docker-for-mac/install/
for instructions.You also need to install VirtualBox. Visit
https://www.virtualbox.org/wiki/Downloads
for instructions.The following assumes you've installed the Homebrew package manager. Visit
https://brew.sh/
for instructions.Install Minikube and Kubectl
To install Minikube, run the following command:
To install Kubectl, run the following command:
Install Helm and Tiller
The following installs both Helm and Tiller.
Bring Up a Kubernetes Cluster
Start a minikube cluster as follows. This automatically runs inside VirtualBox.
To see that it's running, type
You should see something like the following
You can also see how the cluster is configured by looking at
~/.kube/config
.Other tools described on this page use this configuration file to find your cluster.If you want, you can see minikube running by looking at the VirtualBox dashboard.Or alternatively, you can visit the Minikube dashboard:
As a final setp, you need to start Tiller on the Kubernetes cluster.
Download CORD Helm-Charts
You don't need to download all of CORD. You just need to download a set of helm charts. They will, in turn, download a collection of CORD containers from DockerHub. The rest of this section assumes all CORD-related downloads are placed indirectory
~/cord
.Bring Up CORD
An instantiation of CORD typically includes a set of micro-servicesthat collectively implement the Platform plus a Profile thatincludes a collection of access devices and VNFs. In this quick startwe are going to bring up a subset of the Platform that includes XOS,Kafka, Monitoring, and Logging (i.e., everything except ONOS), andthen instead of a Profile tied to a specific access technology, we aregoing to just bring up a demonstration service.
Install XOS
To install
xos-core
(plus affiliated micro-services) into your Kubernetes cluster, execute the following from the ~/cord/helm-charts
directory:Mac Computer Power Cord
You also need to start the Kafka message bus to catch event notifications send by the various components:
Use
kubectl get pods
to verify that all containers that implement XOS (and Kafka) are successfully running. You should see output that looks something like this:Install Monitoring and Logging
Although not required, we recommend that you also bring up two auxilary services to capture and display monitoring and logging information. This is done by executing the following Helm charts.
Monitoring (once running, access Grafana Dashboard at port 31300):
Mac Book Charging Cord
Logging (once running, access Kibana Dashboard at port 30601):
Note: The
-f examples/logging-single.yaml
option says to not use persistent storage, which is fine for development or demo purposes, but not for operational deployments. Install SimpleExampleService
Optionally, you can bring up a simple service to be managed by XOS. This involves deploying two additional helm charts:
base-kubernetes
and demo-simpleexampleservice
. Again from the ~/cord/helm-charts
directory, execute the following:When all the containers are successfully up and running,
kubectl get pod
will return output that looks something like this:The two
tosca-loader
items with Completed
status are jobs, as opposed to pods. Their job is to load TOSCA-based provisioning and configuration information into XOS, and so they run to complettion and then terminate. It is not uncommon to see them in an Error
state as they retry while waiting for the corresponding services to come on-line. Visit CORD Dashboard

Finally, to view the CORD dashboard, run the following:
This will launch a window in your default browser. Administrator login and password are defined in
~/cord/helm-charts/xos-core/values.yaml
