Also, I will cover the additional setup required to set up GPU acceleration for each of the 8-GPU equipped servers.Kernel Panic error come usually when kernel corrupt or if after kernel update it will get panic error if the kernel update had done wrong or any miss updated package It should have been fairly straightforward, but there were some nitty gritty things that I encountered along the way.

The next part will focus on how to set up the master K8s node and getting the slave nodes to join it.

It’s just a script to run docker load command for all the containers in the directory.Īt this juncture, your system is ready to run kubeadm. To load all containers in the directory into your Kubernetes Computer’s docker repository. If you have downloaded my containers zip bundle v1.8.1_k8s_containers.zip, you can run : Load Docker Images into the Kubernetes ComputerĬentOS should come with Python to run python scripts.

Example here is pulling the kube-apiserver-amd64, v1.8.1.ĭocker pull gcr.io/google_containers/kube-apiserver-amd64:v1.8.1ĭocker save gcr.io/google_containers/kube-apiserver-amd64:v1.8.1 > kube-apiserver.tarĪlternatively, the easy way is to download all the tar files I used for my working install here. You can pull the container images one-by-one individually using the following command. Those that start with gcr.io/google_containers and weaveworks are what you need. You can inspect an existing kubeadm installation to see the container list after installing kubeadm on an online machine. Which is a great design as the underlying operating system is kept relatively “clean” compared to something like OpenStack. Kubeadm runs most required Kubernetes components on container images. In k8s.conf, add the lines -nf-call-ip6tables = 1 dev/VolGroup00/LogVol02 swap swap defaults 0 0 Remove/comment swap entries in /etc/fstab. Systemctl enable docker & systemctl start docker Yum install docker Getting the System Ready (same steps as above using yum –download-only) Alternatively, download the docker rpm as well on a live internet machine.

Configure your distribution for local repository. It should be available in the repository of your linux distribution. Install Dockerįollow the steps to install Docker here: To install all the rpm files that you downloaded. Install kubeadm, kubectl, kubelet and kubernetes-cni and start kubelet services. Of course, you may want to download the latest and greatest ones. These are the ones that I tested against.

It’s all here in a zip archive for you lazy ones. See the link below for a guide on how to use yum –downloadonly. You can use yum –downloadonly to download all required rpms. I am doing this on a CentOS 7 system so the repository handling will be yum-based.

You will need a PC with internet access to do this installation for downloading of RPMs and Docker Images. However, Kubeadm is still largely online-based, an internet connection is assumed. For our offline installation, we mirror-ed closely the Kubeadm setup steps whenever we could. Kubeadm is an installer for Kubernetes, and is well-supported by the K8s community. I jumped at the chance to experiment with containers and K8s and volunteered.

GPU Acceleration: Our users who run tensorflow algorithms required GPU acceleration within their containers.

Offline Install : There is and will be a security air gap between the servers and the external internet world, meaning that we would have to install Kubernetes in an offline way.

Easy horizontal scaling : One should be able to easily add new servers to the cluster.

The containers should be put into the appropriate server that can serve its requirements.

Resource management – The user should not need to manage the resources of the cluster.

Each server had 8 GTX1080Ti NVIDIA GPUs in it, and 512GB of ram, and 72 CPU cores. A while back, I had the chance to set up a Kubernetes cluster on a group of GPU-enabled servers at my workplace.
