Introduction

The document provides guidance to install the ote-stack platform on AI Edge Blueprint, which covers the information of hardware requirement, prerequisite software and the detailed step. The ote-stack platform can be installed on Kubernetes or on a system with Docker support. The IEC cluster, which is based on Kubernetes, is chosen to be the edge infrastructure for AI Edge. The installation guide of IEC R2 can be got in here. 

The guide shows step by step to deploy ote-stack platform with one edge cluster as well as add a new edge cluster to management.

How to use this document

The guide covers the details of pre-installation requirements, installation steps and uninstallation guide. The installation steps should be executed before the prerequisites and pre-installation requirements are ready. In addition, one IEC edge cluster with 3 nodes needs to be prepared in advance.

Deployment Architecture

The Deployment Architecture uses one IEC edge cluster with 3 nodes as the basic infrastructure and the ote-stack platform will installed on the cluster.

Pre-Installation Requirements

Hardware Requirements

This section describes the requirements for building IEC edge infrastructure and ote-stack platform. At least three edge nodes are needed to build the edge infrastructure. 

Minimum Hardware Requirements

HW Aspect

Requirement

1 Jumpserver

A physical or virtualized machine that has direct network connectivity to the edge nodes.
For virtual deployments, CPU/RAM/disk requirements of cluster nodes should be satisfiable as virtual machine resources when using the jumpserver as a hypervisor.

CPUMinimum 1 socket for IEC and 2 socket for ote-stack components and usecase test (each cluster node)
RAMMinimum 4GB/server (Depending on usecase work load)
DiskMinimum 20GB (each cluster node)
NetworksMininum 1

Recommended Hardware Requirements

3 Huawei TaiShan 2280 Arm Server are required: 

Processor

2*Kunpeng  920 processor

RAM

12*32G-DDR4-2666MT/s

Storage

3*3.5 inch 4000G SATA and 1*2.5 inch 3200G NVMe SSD

Network

1 onboard network card, each card supports 4*GE port or 4*10GE port or 4*25GE port

Refer TaiShan 2280 Server User Guide here

Software Prerequisites

  • Available harbor (>=1.7, <2.0) with admin user and password
  • At least one IEC edge cluster with healthy container network. 

Database Prerequisites (option)

A mysql database is required to store the related metadata of OTE models, like users, businesses, projects, apps, deployments, clusters, nodes, etc. When the OTE runs, the OpenAPI Server will connect to the database "sys_ote_manage_platform" for providing services. Some brief description of tables which related to this database are shown below:

  • tb_system_config stores global configuration of OTE web portal.
  • tb_business_info maintains the relation between the users of OTE and the namespace which divide cluster resources between different users.
  • tb_ote_web_users stores the informations of general users and administrator in OTE stack.
  • tb_ote_web_repository_users stores the information of users of harbor server for pulling docker images when applications are being deployed. 
  • tb_ote_cluster_label stores the labels which are attached to edge clusters, while the information of clusters are stored as CRD resource in the etcd.
  • tb_ote_node_label stores the labels which are attached to edge nodes, while the information of edge nodes are stored as CRD resource in the etcd.
  • tb_app_info stores the information about application that will be deployed, such as name, image, required resource, execution command.
  • tb_deploy_info maintains the information and status of deployments related to the application that stored in tb_app_info.
  • tb_alert_info displays alert messages sent by alertmanager server. 

Following the installation steps below, a new mysql database container, which contains the configuration and db tables of OTE, will be deployed to the edge cluster. If you need to store these OTE metadata in your own database, you can execute the following schema script to create the database and the related tables.

Schema scripts

The following schema scripts will help you to generate the database for OTE-stack.

Creating a Node Inventory File

N/A

Creating the Settings Files

Copy the kubeconfig file of IEC cluster to directory /root/.kube/config.

Clone the AIEdge git repo and edit the configuration file (interface_conf) by setting:

  • hostname of the node in edge cluster that the ote-stack platform will be deployed to
  • docker repository for pulling images of ote-stack components
  • informations of harbor repository such as admin password and domain
git clone https://gerrit.akraino.org/r/aiedge.git
cd aiedge
git submodule init
git submodule update
cd ote-stack/deployments
vim interface_conf

Running

Prerequisite

Compile cluster controller, controller manager and shim components following below scripts. Then docker push the output image to a docker repository which is set in the interface_conf file.

bash build/build.sh build_image

Other components are not source code released currently but released as docker images, and they can be pull from docker hub. Make sure that the docker repository set in the configuration file have all docker images required by ote-stack platform.

Deploy ote-stack on one IEC cluster

Simply start the installation script with default parameters in the same directory:

# create yaml file based on interface_conf
sh create_yml.sh start
# apply yaml file to cluster
sh apply_yml.sh start

All components of ote-stack will be installed on the IEC edge. But some components can be replaced with external ones outside the cluster through changing the parameter of yaml file. For example, the open-api server can connect to an existing mysql server by modifying the parameters `mysqlHost` and `mysqlPort` in file deployments/open-api/open-api.yml and commenting out the line to deploy mysql. 

After executing the installation script, the ote-stack web platform will be deployed on the node1_name set in the configuration file and expose port 8995. Now you can open the website through URL http://<node1_name_ip>:8995/ to use ote-stack. Below is the the index page of OTE.

When ote-stack runs, a super administrator will be created. The username and password can be modified by changing parameters `superAdminName` and `superAdminPassword` in file deployments/open-api/open-api.yml.  Note that the initial username and password of admin, only works for the first time when ote-stack starts.

Add a new cluster to ote-stack for management (option)

If there is another cluster that needs to be added to the ote-stack, some components should be deployed on the edge to connect with root cluster:

  • tiller/ tiller-proxy
  • ote-shim/ ote-cc
  • node-agent/ nodes-server/ prometheus
  • exporters like node-exporte (optional)
  • fluent-bit (optional)
