ii LiCO 6.0.0 Kubernetes Installation Guide (for SLES)

Chapter 1. Overview

IntroductionKubernetes is a portable, extensible, open-source platform for managing heavy workload and services, which facilitates declarative configuration and automation.

Lenovo Intelligent Computing Orchestration (LiCO) is a platform for AI model training. It provides AI job management and file management based on Kubernetes.

This guide provides the instructions on installing LiCO for Kubernetes.

Typical cluster deployment

Figure 1. Typical cluster deployment

Elements in typical deployment are described in the table below. For the example of deployment, refer to “Example of LiCO Kubernetes deployment” on page 21.

Table 1. Description of elements in the typical deployment

Element Description

LiCO node The node deploying LiCO, which can be a physical machine or a virtual machine.

Kubernetes clusterLiCO schedules AI jobs to Kubernetes cluster. The Kubernetes versions supported by LiCO are V1.8–V1.17. Kubernetes cluster setup is beyond the scope of LiCO. For more information about setting up a Kubernetes cluster, refer to https://kubernetes.io/docs/home/.

Parallel file systemParallel file system provides shared storage for Kubernetes. The pods in Kubernetes can use the shared storage through PV and PVC. Parallel file system setup is beyond the scope of LiCO.

Operating environmentOperating system for LiCO node:

SUSE Linux Enterprise server (SLES) 15 SP1

© Copyright Lenovo 2019, 2020 1

https://kubernetes.io/docs/home/

Client requirements:

• Hardware: CPU of 2.0 GHz or above, memory of 8 GB or above

• Browser: Chrome (V 62.0 or higher) or Firefox (V 56.0 or higher) is recommended

• Display resolution: 1280 x 800 or above

Prerequisites• Unless otherwise stated in this guide, all commands should be executed on the LiCO node.

• If the NTP service is installed in the Kubernetes cluster, set the NTP client in LiCO node.

• LiCO uses Kubernetes stream to execute command and collect output of command, so the configuration item of kubelet streaming-connection-idle-timeout should be set to “no time-out”. If Kubernetes APIServer is deployed with the load balancer, the time-out between the load balancer and APIServer should be set to large number.

• To avoid security vulnerabilities, it is recommended to regularly patch and update components and OS.

Example of LiCO Kubernetes deploymentThe following architecture is an example of LiCO Kubernetes deployment, which may be different with the actual Kubernetes. LiCO will not automatically set up Kubernetes cluster. Therefore, ensure LiCO can access Kubernetes master and ingress controller.

LiCO uses Kubernetes stream to execute command and collect output of command, so the configuration item of kubelet streaming-connection-idle-timeout should be set to “no time-out”. If Kubernetes APIServer is deployed with the load balancer, the time-out between the load balancer and APIServer should be set to large number.


https://documentation.suse.com/sles/15-SP1/html/SLES-all/book-security.html

Figure 2. LiCO Kubernetes deployment

Following are the descriptions for each component of LiCO Kubernetes deployment:

Internal network: • All nodes in the Kubernetes cluster can be connected through internal network.• Kubernetes cluster is set up and configured in internal network.• Pods can read/write shared data in the storage node by using PV/PVC in internal network.• Pods in different nodes are interacted with each other through internal network.

External network: • All nodes in the Kubernetes cluster can be connected through external network.• LiCO accesses Kubernetes master and ingress controller through external network. The services

automatically deployed by LiCO are exposed through ingress.• The storage node can be exposed through external network. To upload the big-size file, user should

access the storage node directly.• The harbor is exposed through external network. User can push docker images to the harbor. Pods pull

docker images from the harbor.

Internet: • If external network is connected to Internet, pods can access Internet and pull docker images on Internet.

LiCO node:


• LiCO is deployed on the LiCO node (physical machine or virtual machine), and connects to external network.

• LiCO provides Web portal. User can access LiCO through Web browser.

Troubleshooting creating image issuesIf the following error message is displayed when creating images, perform the following steps:

ImportError: libcuda.so.1: cannot open shared object file: No such file or directory

Step 1. Edit or create the /etc/docker/daemon.json file with the following content:

{

"runtimes": {

"nvidia": {

"path": "nvidia-container-runtime",

"runtimeArgs": []

}

},

"default-runtime": "nvidia"

}

Step 2. Install the nvidia-container-runtime package.

Step 3. Restart Docker service.
