How to deploy with Helm* Chart#
This section shows how to deploy the Video Search and Summary Sample Application using Helm chart.
Prerequisites#
Before you begin, ensure that you have the following:
Kubernetes* cluster set up and running.
The cluster must support dynamic provisioning of Persistent Volumes (PV). Refer to the Kubernetes Dynamic Provisioning Guide for more details.
Install
kubectlon your system. See the Installation Guide. Ensure access to the Kubernetes cluster.Helm chart installed on your system. See the Installation Guide.
Storage Requirement : Application requests for 50GiB of storage in its default configuration. (This should change with choice of models and needs to be properly configured). Please make sure that required storage is available in you cluster.
Video Search and Summary requires PVC storage class to support
RWManymode. In case the default storage class used does not support it, consider using storage solution like LongHorn that provides this support. Video Search and Summary intends to remove this prerequisite in future release and use onlyRWOncemode.
Helm Chart Installation#
In order to setup the end-to-end application, we need to acquire the charts and install it with optimal values and configurations. Subsequent sections will provide step by step details for the same.
1. Acquire the helm chart#
There are 2 options to get the charts in your workspace:
Option 1: Get the charts from Docker Hub#
Step 1: Pull the Specific Chart#
Use the following command to pull the Helm chart from Docker Hub:
helm pull oci://registry-1.docker.io/intel/video-search-and-summarization --version <version-no>
Refer to the release notes for details on the latest version number to use for the sample application.
Step 2: Extract the .tgz File#
After pulling the chart, extract the .tgz file:
tar -xvf video-search-and-summarization-<version-no>.tgz
This will create a directory named video-search-and-summarization containing the chart files. Navigate to the extracted directory to access the charts.
cd video-search-and-summarization
Option 2: Install from Source#
Step 1: Clone the Repository#
Clone the repository containing the Helm chart:
git clone https://github.com/open-edge-platform/edge-ai-libraries.git
Step 2: Change to the Chart Directory#
Navigate to the chart directory:
cd edge-ai-libraries/sample-applications/video-search-and-summarization/chart
2. Configure Required Values#
The application requires several values to be set by user in order to work. To make it easier, we have included a user_values_override.yaml file, which contains only the values that user needs to tweak. Open the file in your favorite editor or use nano:
nano user_values_override.yaml
Update or edit the values in YAML file as follows:
Key |
Description |
Example Value |
|---|---|---|
|
Name for PVC to be used for storage by all components of application |
|
|
PVC gets deleted by default once helm is uninstalled. Set this to true to persist PVC (helps avoid delay due to model re-downloads when re-installing chart). |
|
|
Your Hugging Face API token |
|
|
HTTP proxy if required |
|
|
HTTPS proxy if required |
|
|
VLM model to be used by VLM Inference Microservice |
|
|
LLM model to be used by OVMS (used only when OVMS is enabled) |
|
|
PostgreSQL user |
|
|
PostgreSQL password |
|
|
MinIO server user name |
|
|
MinIO server password |
|
|
RabbitMQ username |
|
|
RabbitMQ password |
|
|
OTLP endpoint |
Leave empty if not using telemetry |
|
OTLP trace endpoint |
Leave empty if not using telemetry |
|
Name of object detection model used during video ingestion |
|
|
Type/Category of the object detection Model |
|
|
Embedding model name used in unified video search and summary |
|
|
Embedding model name used in standalone video search application |
|
3. Build Helm Dependencies#
Navigate to the chart directory and build the Helm dependencies using the following command:
helm dependency update
4. Set and Create a Namespace#
We will install the helm chart in a new namespace. Create a shell variable to refer a new namespace and create it.
Refer a new namespace using shell variable
my_namespace. Set any desired unique value.my_namespace=foobar
Create the Kubernetes namespace. If it is already created, creation will fail. You can update the namespace in previous step and try again.
kubectl create namespace $my_namespace
NOTE : All subsequent steps assume that you have
my_namespacevariable set and accessible on your shell with the desired namespace as its value.
5. Deploy the Helm Chart#
At present, there are 4 use-cases for Video Search and Summarization Application. We will learn how to deploy each use-case using the helm chart.
NOTE : Before switching to a different use-case always stop the current running use-caseās application stack (if any) by uninstalling the chart :
helm uninstall vss -n $my_namespace. This is not required if you are installing the helm chart for the first time.
Use Case 1: Video Summarization Only (Using VLM Microservice)#
Deploy the Video Summarization application:
helm install vss . -f summary_override.yaml -f user_values_override.yaml -n $my_namespace
NOTE : Delete the chart for installing the chart in other modes
helm uninstall vss -n $my_namespace
Use Case 2: Video Summarization with OVMS Microservice (OpenVINO Model Serving)#
If you want to use OVMS for LLM Summarization, deploy with the OVMS override values:
helm install vss . -f summary_override.yaml -f ovms_override.yaml -f user_values_override.yaml -n $my_namespace
Note: When deploying OVMS, the OVMS service may take more time to start due to model conversion.
Use Case 3: Video Search Only#
To deploy only the Video Search functionality, use the search override values:
helm install vss . -f search_override.yaml -f user_values_override.yaml -n $my_namespace
Use Case 4: Unified Video Search and Summarization#
To deploy only the Video Search functionality, use the search override values:
helm install vss . -f unified_summary_search.yaml -f user_values_override.yaml -n $my_namespace
Step 6: Verify the Deployment#
Check the status of the deployed resources to ensure everything is running correctly:
kubectl get pods -n $my_namespace
Before proceeding to access the application we must ensure the following status of output of the above command:
Ensure all pods are in the āRunningā state. This is denoted by Running state mentioned in the STATUS column.
Ensure all containers in each pod are Ready. As all pods are running single container only, this is typically denoted by mentioning 1/1 in the READY column.
IMPORTANT NOTE : When deployed for first time, it may take up-to around 50 Mins to bring all the pods/containers in running and ready state, as several containers try to download models which can take a while. The time to bring up all the pods depends on several factors including but not limited to node availability, node load average, network speed, compute availability etc.
IMPORTANT NOTE : If you want to persist the downloaded models and avoid delays pertaining to model downloads when re-installing the charts, please set the
global.keepPvcvalue totrueinuser_values_override.yamlfile before installing the chart.
Step 7: Accessing the application#
Nginx service running as a reverse proxy in one of the pods, helps us to access the application. We need to get Host IP and Port on the node where the nginx service is running.
Run the following command to get the host IP of the node and port exposed by Nginx service:
vss_hostip=$(kubectl get pods -l app=vss-nginx -n $my_namespace -o jsonpath='{.items[0].status.hostIP}')
vss_port=$(kubectl get service vss-nginx -n $my_namespace -o jsonpath='{.spec.ports[0].nodePort}')
echo "http://${vss_hostip}:${vss_port}"
Copy the output of above bash snippet and paste it into your browser to access the Video Search and Summarization Application.
Step 8: Update Helm Dependencies#
If any changes are made to the sub-charts, always remember to update the Helm dependencies using the following command before re-installing or upgrading your helm installation:
helm dependency update
Step 9: Uninstall Helm chart#
To uninstall the Video Summary Helm chart, use the following command:
helm uninstall vss -n $my_namespace
Updating PVC Storage Size#
If any of the microservice requires more or less storage than the default allotted storage in values file, this can be overridden for one or more services.
Updating storage for VDMS-Dataprep and MultiModal Embedding Service#
Set the required sharedClaimSize value while installing the helm chart.
For example, if installing chart in search only mode :
helm install vss . -f search_override.yaml -f user_values_override.yaml --set sharedClaimSize=10Gi -n $my_namespace
If installing the chart in combined search and summary mode :
helm install vss . -f unified_summary_search.yaml -f user_values_override.yaml --set sharedClaimSize=10Gi -n $my_namespace
Updating storage for other microservices#
To update storage for other microservices we can, override the corresponding claimSize value in the main chart values file, while installing the chart.
For example, for updating storage for VLM-Inference Microservice in summary mode :
helm install vss . -f summary_override.yaml -f user_values_override.yaml --set vlminference.claimSize=50Gi -n $my_namespace
Similarly, for updating storage for OVMS in summary mode, we can install the chart in following ways :
helm install vss . -f summary_override.yaml -f user_values_override.yaml -f ovms_override.yaml --set ovms.claimSize=10Gi -n $my_namespace
Letās look at one more example, for updating storage for Minio Server in combined search and summary mode :
helm install vss . -f unified_summary_search.yaml -f user_values_override.yaml --set minioserver.claimSize=10Gi -n $my_namespace
If not set while installing the chart, all services will claim a default amount of storage set in the values file.
Verification#
Ensure that all pods are running and the services are accessible.
Access the Video Summary application dashboard and verify that it is functioning as expected.
Upload a test video to verify that the ingestion, processing, and summary pipeline works correctly.
Check that all components (MinIO, PostgreSQL, RabbitMQ, video ingestion, VLM inference, audio analyzer) are functioning properly.
Troubleshooting#
Pods not coming in Ready or Running state for a long time.
There could be several possible reasons for this. Most likely reasons are storage unavailability, node unavailability, network slow-down or faulty network etc. Please check with your cluster admin or try fresh installation of charts, after deleting the PVC (see next issue) and un-installing the current chart.
All containers Ready, all Pods in Running state, application UI is accessible but search or summary is failing.
If PVC has been configured to be retained, most common reason for application to fail to work is a stale PVC. This problem most likely occurs when helm charts are re-installed after some updates to helm chart or the application image. To fix this, delete the PVC before re-installing the helm chart by following command:
kubectl delete pvc vss-shared-pvc -n <your_namespace>
If you have updated the
global.pvcNamein the values file, use the updated name instead of default PVC namevss-shared-pvcin above command.If you encounter any issues during the deployment process, check the Kubernetes logs for errors:
kubectl logs <pod-name> -n $my_namespace
For component-specific issues:
Video ingestion problems: Check the logs of the videoingestion pod
VLM inference issues: Check the logs of the vlm-inference-microservice pod
Database connection problems: Verify the PostgreSQL pod is running correctly
Storage issues: Check the MinIO server status and connectivity
Some issues might be fixed by freshly setting up storage. This is helpful in cases where deletion of PVC is prohibited by configuration on charts un-installation (when
global.keepPvcis set to true):kubectl delete pvc <pvc-name> -n $my_namespace
If youāre experiencing issues with the Hugging Face API, ensure your API token
global.huggingfaceTokenis valid and properly set in theuser_values_override.yamlfile.
