Build and Run the Smart City Sample on Public Cloud or Local Machine

The Open Visual Cloud is highly optimized for the latest Intel® Xeon® Scalable Processors. Developers can use their own x86 development system to build, customize, and evaluate Open Visual Cloud reference pipelines, or use a public cloud to assess system scalability and performance.
 
This tutorial builds and runs the Smart City Sample on the Amazon Web Services (AWS), Azure Virtual Machine and Google Cloud Platform Virtual Machine (GCP) or your local machine. The following figures show the running compute instances of the 3 cloud services.

AWS EC2 INSTANCE, AMAZON LINUX 2

AZURE VM INSTANCE, UBUNTU 16.04 LTS

GOOGLE CLOUD PLATFORM VM INSTANCE, UBUNTU 16.04 LTS

Unless specifically specified, all the commands in the tutorial apply to all the 3 cloud services.

1. Prerequisites

For AWS, run the following commands to install the software packages required to build the sample:

$ sudo yum update –y

$ sudo amazon-linux-extras install –y docker

$ sudo service docker start

$ sudo yum install –y cmake git
For Azure and GCP, follow https://docs.docker.com/install/linux/docker-ce/debian/ to install docker.ce.
 
Run the following command to install cmake and git
$ sudo apt-get install –y cmake git
Initialize docker swarm as we will use docker swarm for deployment.
$ sudo docker swarm init

Swarm initialized: current node (04k9ydxpdtx40nym8ag2j499r) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-2jthey7uay7ym5ko1db4etp9lt5sjmi8u4qhkv4owe1ysip943-5novs363q4nby8kgaek8ury6i 172.31.18.164:2377

2. Clone the Sample Source Code

Run the following command to clone the Smart City Sample source code:

$ git clone https://github.com/OpenVisualCloud/Smart-City-Sample

 

3. Build the Sample

Run the following commands to build the Smart City Sample. The build time is about 2 hours on t2.large. 
$ cd Smart-City-Sample

$ mkdir build

$ cd build

$ cmake ..

This script will build third party components licensed under various open source licenses into your container images. 

The terms under which those components may be used and distributed can be found with the license document that is 

provided with those components. Please familiarize yourself with those terms to ensure your distribution of those 

components complies with the terms of those licenses.

5. Test the Sample

The Smart City Sample exposes a web interface at port 443. We need to create a SSH tunnel to access it, as follows:

For AWS

$ ssh -L 8443:localhost:443 -Nf -i "keypair.pem" ec2-user@3.17.131.107

The SSH tunnel maps localhost port 443 to the AWS EC2 instance port 443, and “keypair.pem” is the ssh access key pair generated for accessing the AWS EC2 instance.
Open your browser to https://localhost:8443 and accept the self-signed certificate to proceed to the sample UI. 

 

For Azure or GCP

For Azure or GCP, the command is almost the same.

$ ssh -L 8443:localhost:443 -Nf -i ssh_private_key user_name@instance_public_ip

ssh_private_key is ssh access private key for accessing Azure or GCP VM instances.
Open your browser to https://localhost:8443 and accept the self-signed certificate to proceed to the sample UI. 
Clicking camera icon  will bring the recorded video page of the camera.
Clicking preview video on the home page will also bring the recorded video page of the camera which is currently associated with the preview.
 

User can click office icon   to bring office page to get information of server workload, algorithm status, etc.
