Preparing the node

  • Create new user "kubernetes" with groups docker and sudo.
  • Follow the steps to install docker, nvidia-docker2 and make nvidia-docker the default runtime on the node.
  • Follow instructions on this page to install Kubernetes and pre-requisites.

Spin up the slave node

On the master node: 

> cd init
> ./show_join_command.sh

Copy the output into a new file "join_cluster.sh" in the init directory of the slave.

On the slave: 

> cd init
> chmod +x join_cluster.sh
> sudo ./join_cluster.sh


There are problems with the flannel network currently, which requires manual patching of the node after installation, and restarting the flannel pod: 

> kubectl patch node <NODE_NAME> -p '{"spec":{"podCIDR":"10.244.0.0/16"}}'
