Deploy Multiple Instances with Helm#

Prerequisites#

Ensure you have the minimum system requirements for this application.
K8s installation on single or multi node must be done as pre-requisite to continue the following deployment. Note: The kubernetes cluster is set up with kubeadm, kubectl and kubelet packages on single and multi nodes with v1.30.2. Refer to tutorials online to setup kubernetes cluster on the web with host OS as ubuntu 22.04 and/or ubuntu 24.04.
For helm installation, refer to helm website

Setup the application#

Note: The following instructions assume Kubernetes is already running in the host system with helm package manager installed.

Clone the edge-ai-suites repository and change into industrial-edge-insights-vision directory. The directory contains the utility scripts required in the instructions that follows.
```
git clone https://github.com/open-edge-platform/edge-ai-suites.git
cd edge-ai-suites/manufacturing-ai-suite/industrial-edge-insights-vision/
```
Note: These steps demonstrate launching two weld-porosity instances and one pallet-defect-detection instance. Modify the sample apps and instances as needed for your use case.
Create a config.yml file to define your application instances and their unique port configurations. Add the following sample contents and save.

Example:
```
weld-porosity:
  weld1:
    NGINX_HTTP_PORT: 30080
    NGINX_HTTPS_PORT: 30443
    COTURN_PORT: 30478
    S3_STORAGE_PORT: 30800
  weld2:
    NGINX_HTTP_PORT: 30081
    NGINX_HTTPS_PORT: 30444
    COTURN_PORT: 30479
    S3_STORAGE_PORT: 30801

pallet-defect-detection:
  pdd1:
    NGINX_HTTP_PORT: 30082
    NGINX_HTTPS_PORT: 30445
    COTURN_PORT: 30480
    S3_STORAGE_PORT: 30802
```
Note: A sample configuration file sample_config.yml is provided to help users understand the multi-instance setup and get started. This configuration defines three example instances with identifiers: pdd1, pdd2, and weld1. The accompanying sample scripts utilize these identifiers to perform operations on individual application instances.

Edit the below mentioned environment variables in all the helm/values_<SAMPLE_APP>.yaml files:

HOST_IP=<HOST_IP>   # IP address of server where DL Streamer Pipeline Server is running.

MINIO_ACCESS_KEY=   # MinIO service & client access key e.g. intel1234
MINIO_SECRET_KEY=   # MinIO service & client secret key e.g. intel1234

MTX_WEBRTCICESERVERS2_0_USERNAME=<username>  # WebRTC credentials e.g. intel1234
MTX_WEBRTCICESERVERS2_0_PASSWORD=<password>

Install pre-requisites for all instances
```
./setup.sh helm
```
This does the following:
- Parses through the config.yml
- Downloads resources for each instance
- Creates a folder helm/temp_apps/<SAMPLE_APP>/<INSTANCE_NAME> that contains configs folder, .env file, payload.json, Chart.yaml, pipeline-server-config.json and values.yaml.
- Updates and adds the ports mentioned in config.yml to the respective values.yaml file
- Sets executable permissions for scripts

Deploy the application#

Install helm charts#

Install the helm chart for all instances
```
./run.sh helm_install
```
After installation, check the status of the running pods for each instance:
```
kubectl get pods -n <INSTANCE_NAME>
```
To view logs of a specific pod, replace <pod_name> with the actual pod name from the output above:
```
kubectl logs -n <INSTANCE_NAME> -f <pod_name>
```

Copy the resources such as video and model from local directory to the to the dlstreamer-pipeline-server pod to make them available for application while launching pipelines.

 # Below is an example for Weld Porosity Classification. Please adjust the source path of models and videos appropriately for other sample applications.

 POD_NAME=$(kubectl get pods -n <INSTANCE_NAME> -o jsonpath='{.items[*].metadata.name}' | tr ' ' '\n' | grep deployment-dlstreamer-pipeline-server | head -n 1)

 kubectl cp resources/weld-porosity/videos/welding.avi $POD_NAME:/home/pipeline-server/resources/videos/ -c dlstreamer-pipeline-server -n <INSTANCE_NAME>

 kubectl cp resources/weld-porosity/models/* $POD_NAME:/home/pipeline-server/resources/models/ -c dlstreamer-pipeline-server -n <INSTANCE_NAME>

Start AI pipelines#

Start pipeline for all instances#

Fetch the list of pipeline loaded available to launch for all instances

./sample_list.sh helm

This lists the pipeline loaded in DLStreamer Pipeline Server.

Storing frames to S3 storage#

Applications can take advantage of S3 publish feature from DL Streamer Pipeline Server and use it to save frames to an S3 compatible storage.

Run all the steps mentioned in above section to setup the application.
Install the helm chart.
```
./run.sh helm_install
```

Copy the resources such as video and model from local directory to the dlstreamer-pipeline-server pod to make them available for application while launching pipelines.

 # Below is an example for Weld Porosity Classification. Please adjust the source path of models and videos appropriately for other sample applications.

 POD_NAME=$(kubectl get pods -n <INSTANCE_NAME> -o jsonpath='{.items[*].metadata.name}' | tr ' ' '\n' | grep deployment-dlstreamer-pipeline-server | head -n 1)

 kubectl cp resources/weld-porosity/videos/welding.avi $POD_NAME:/home/pipeline-server/resources/videos/ -c dlstreamer-pipeline-server -n <INSTANCE_NAME>

 kubectl cp resources/weld-porosity/models/* $POD_NAME:/home/pipeline-server/resources/models/ -c dlstreamer-pipeline-server -n <INSTANCE_NAME>

Install the package boto3 in your python environment if not installed.

It is recommended to create a virtual environment and install it there. You can run the following commands to add the necessary dependencies as well as create and activate the environment.
```
sudo apt update && \
sudo apt install -y python3 python3-pip python3-venv
```
```
python3 -m venv venv && \
source venv/bin/activate
```
Once the environment is ready, install boto3 with the following command
```
pip3 install --upgrade pip && \
pip3 install boto3==1.36.17
```
Note: DL Streamer Pipeline Server expects the bucket to be already present in the database. The next step will help you create one.

Create a S3 bucket using the following script.

Update the HOST_IP and S3_STORAGE_PORT mentioned in config.yml for each instance and credentials with that of the running MinIO server. Name the file as create_bucket_<INSTANCE_NAME>.py.

import boto3
url = "http://<HOST_IP>:<S3_STORAGE_PORT>"
user = "<value of MINIO_ACCESS_KEY used in helm/temp_apps/SAMPLE_APP/INSTANCE_NAME/values.yaml>"
password = "<value of MINIO_SECRET_KEY used in helm/temp_apps/SAMPLE_APP/INSTANCE_NAME/values.yaml>"
bucket_name = "ecgdemo"

client= boto3.client(
            "s3",
            endpoint_url=url,
            aws_access_key_id=user,
            aws_secret_access_key=password
)
client.create_bucket(Bucket=bucket_name)
buckets = client.list_buckets()
print("Buckets:", [b["Name"] for b in buckets.get("Buckets", [])])

Run the above script to create the bucket.

python3 create_bucket_<INSTANCE_NAME>.py

Start the pipeline with the following cURL command with <HOST_IP> set to system IP and the <NGINX_HTTPS_PORT> mentioned in the config.yml for each instance. Ensure to give the correct path to the model as seen below. This example starts an AI pipeline for weld-porosity. Please adjust the source path of models and videos appropriately for other sample applications.

 curl -k https://<HOST_IP>:<NGINX_HTTPS_PORT>/api/pipelines/user_defined_pipelines/weld_porosity_classification_s3write -X POST -H 'Content-Type: application/json' -d '{
     "source": {
         "uri": "file:///home/pipeline-server/resources/videos/welding.avi",
         "type": "uri"
     },
     "destination": {
         "frame": {
             "type": "webrtc",
             "peer-id": "welds3"
         }
     },
     "parameters": {
         "classification-properties": {
             "model": "/home/pipeline-server/resources/models/weld-porosity/deployment/Classification/model/model.xml",
             "device": "CPU"
         }
     }
 }'

Go to MinIO console on https://<HOST_IP>:<NGINX_HTTPS_PORT>/minio/ and login with MINIO_ACCESS_KEY and MINIO_SECRET_KEY provided in helm/temp_apps/SAMPLE_APP/INSTANCE_NAME/values.yaml file. After logging into console, you can go to ecgdemo bucket and check the frames stored.
Uninstall the helm chart.
```
./run.sh helm_uninstall
```

MLOps using Model Download#

Run all the steps mentioned in above section to setup the application.
Install the helm chart
```
./run.sh helm_install
```

Copy the resources such as video and model from local directory to the dlstreamer-pipeline-server pod to make them available for application while launching pipelines.

 # Below is an example for Weld Porosity Classification. Please adjust the source path of models and videos appropriately for other sample applications.

 POD_NAME=$(kubectl get pods -n <INSTANCE_NAME> -o jsonpath='{.items[*].metadata.name}' | tr ' ' '\n' | grep deployment-dlstreamer-pipeline-server | head -n 1)

 kubectl cp resources/weld-porosity/videos/welding.avi $POD_NAME:/home/pipeline-server/resources/videos/ -c dlstreamer-pipeline-server -n <INSTANCE_NAME>

 kubectl cp resources/weld-porosity/models/* $POD_NAME:/home/pipeline-server/resources/models/ -c dlstreamer-pipeline-server -n <INSTANCE_NAME>

Modify the payload in helm/temp_apps/<SAMPLE_APP>/<INSTANCE_NAME>/payload.json to launch an instance for the mlops pipeline.

 [
     {
         "pipeline": "weld_porosity_classification_mlops",
         "payload": {
             "destination": {
                 "frame": {
                     "type": "webrtc",
                     "peer-id": "weld"
                 }
             },
             "parameters": {
                 "classification-properties": {
                     "model": "/home/pipeline-server/resources/models/weld-porosity/deployment/Classification/model/model.xml",
                     "device": "CPU"
                 }
             }
         }
     }
 ]

Start the pipeline with the above payload.

./sample_start.sh helm -i <INSTANCE_NAME> -p weld_porosity_classification_mlops

Note the instance-id.

Download and prepare the model. Below is an example for downloading and preparing model for weld-porosity-classification. Please modify MODEL_URL for the other sample applications.

NOTE- For sake of simplicity, we assume that the new model has already been downloaded by Model Download microservice. The following curl command is only a simulation that just downloads the model. In production, however, they will be downloaded by the Model Download service.
```
 export MODEL_URL='https://github.com/open-edge-platform/edge-ai-resources/raw/a7c9522f5f936c47de8922046db7d7add13f93a0/models/FP16/weld_porosity_classification.zip'

 curl -L "$MODEL_URL" -o "$(basename $MODEL_URL)"

 unzip "$(basename $MODEL_URL)" -d new-model # downloaded model is now extracted to `new-model` directory.
```

Copy the new model to the dlstreamer-pipeline-server pod to make it available for application while launching pipeline.

 POD_NAME=$(kubectl get pods -n <INSTANCE_NAME> -o jsonpath='{.items[*].metadata.name}' | tr ' ' '\n' | grep deployment-dlstreamer-pipeline-server | head -n 1)

 kubectl cp new-model $POD_NAME:/home/pipeline-server/resources/models/ -c dlstreamer-pipeline-server -n <INSTANCE_NAME>

NOTE- If there are multiple sample_apps in config.yml, repeat steps 6 and 7 for each sample app and instance.

Stop the existing pipeline before restarting it with a new model. Use the instance-id generated from step 5.
```
curl -k --location -X DELETE https://<HOST_IP>:<NGINX_HTTPS_PORT>/api/pipelines/{instance_id}
```

Modify the payload in helm/temp_apps/<SAMPLE_APP>/<INSTANCE_NAME>/payload.json to launch an instance for the mlops pipeline with this new model.

Below is an example for weld-porosity-classification. Please modify the payload for other sample applications.

 [
     {
         "pipeline": "weld_porosity_classification_mlops",
         "payload": {
             "destination": {
                 "frame": {
                     "type": "webrtc",
                     "peer-id": "weld"
                 }
             },
             "parameters": {
                 "classification-properties": {
                     "model": "/home/pipeline-server/resources/models/new-model/deployment/Classification/model/model.xml",
                     "device": "CPU"
                 }
             }
         }
     }
 ]

View the WebRTC streaming on https://<HOST_IP>:<NGINX_HTTPS_PORT>/mediamtx/<peer-str-id>/ by replacing <peer-str-id> with the value used in the original cURL command to start the pipeline.
