Development Cluster Configuration

These packages form the basic functionality of the development cluster. The packages need to be installed in this order to preserve the IP address assignments. If the order is changed (or one is left out) you may need to review and modify IP assignments in the DNS server on the firewall.

Scripts & config files are checked into gitlab under the Kubernetes group project listed.

activity	gitlab	script/procedures/config	IP	hostname(s)
BeeGFS Installation	install the parallel filesystem components on controller & nodes to support the /workspace filesystem
NVIDIA device plugin		https://github.com/NVIDIA/k8s-device-plugin
K8Dash Dashboard	k8s-admin		10.0.0.200
Dynamic Provisioning	k8s-admin	(k8s-admin wiki)
Harbor Registry	k8s-admin		10.0.0.201	harbor-dev.williams.localnet

Storage

The production cluster depends on the /workspace filesystem for its persistent storage. The BeeGFS components are installed as shown here:

component	system	location	storage	size
Management Server	controller	/beegfs/beegfs-mgmtd	local SSD	~200G (shared with OS)
Metadata Server	controller	/beegfs/beegfs-meta	local SSD	~200G (shared with OS)
Storage Server	controller	/ws_data/beegfs/beegfs-storage	mounted from Equalogic array	7.9T
Storage Server	storage1	/ws_data_2	local 5x4TB RAID5 array	15T

Systems that require access to both the development filesystem (/workspace) and the production filesystem (/shared) require a special client configuration.

Dashboard Token

Obtain the current dashboard token with these commands:

kubectl create serviceaccount k8dash-sa
kubectl create clusterrolebinding k8dash-sa --clusterrole=cluster-admin --serviceaccount=default:k8dash-sa
kubectl describe secrets `kubectl get secrets | awk '/k8dash-sa/ {print $1}'` | awk '/token:/ {print $2}'

The current Development cluster dashboard token is:
