Prerequisities
| Action | Notes |
|---|---|
| Basic CentOS 7 Installation | the kubernetes cluster is based on the standard install of Centos 7 for all systems/nodes |
| Ethernet Device Configuration | for convenience rename network devices to eth* (optional) |
| CUDA + NVIDIA drivers | if the node has a GPU, install the drivers and libraries |
| Ceph Storage Cluster | install the parallel filesystem components as needed |
| Docker Installation | Docker is required for all nodes |
| IP Tables config | set up the system config to use IP Tables properly |
Kubernetes Cluster
There are multiple ways to deploy a kubernetes cluster. These two have been tried and are (at least somewhat) functional.
kubeadm
Full instructions for creating a cluster using kubeadm are located in the kubernetes documentation: https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/create-cluster-kubeadm/
| Kubernetes Controller | install kubernetes cluster controller |
| Kubernetes Nodes | install kubernetes nodes |
k3s
See the K3s - Kubernetes Simplified page for instructions
The Rest of the Stuff
These are the parts of the cluster that may be installed by one of the above methods, but not always.
| IP Controller | set up load balancer to assign IP addresses when needed |
| Metrics Server | install metrics collection for the dashboard |
| k8dash Dashboard | install the web GUI dashboard<ref>the original/default kubernetes dashboard installation instructions are located at kubernetes Dashboard</ref> |
| Rook Storage for Kubernetes | dynamic storage provisioning |
| helm installation | kubernetes package installer |
Final Configuration
Now load the rest of the packages for each cluster:
