​
Deployment Steps

​
Prerequisites

Ensure the following tools are installed:

  • Docker
  • Kubectl
  • Helm (v3 or above)

​
Step 1: Clone the Portkey repo containing helm chart

git clone https://github.com/Portkey-AI/helm-chart

​
Step 2: Update values.yaml for Helm

Modify the values.yaml file in the Helm chart directory to include the Docker registry credentials and necessary environment variables. You can find the sample file at ./helm-chart/helm/enterprise/values.yaml

Image Credentials Configuration

imageCredentials:
  name: portkey-enterprise-registry-credentials
  create: true
  registry: kubernetes.io/dockerconfigjson
  username:
  password:

The Portkey team will share the credentials for your image

Environment Variables Configuration

    MONGO_DATABASE:
    MONGO_COLLECTION_NAME:

    REDIS_URL:

    ORGANISATIONS_TO_SYNC:

Notes on the Log Store LOG_STORE can be

  • an S3 compatible store (AWS S3 s3, GCS gcs, Wasabi wasabi)
  • or a MongoDB store (Hosted MongoDB mongo, AWS DocumentDB mongo)

If the LOG_STORE is mongo, the following environment variables are needed

MONGO_DB_CONNECTION_URL:
MONGO_DATABASE:
MONGO_COLLECTION_NAME:

If the LOG_STORE is s3 or wasabi or gcs, the following values are mandatory

LOG_STORE_REGION:
LOG_STORE_ACCESS_KEY:
LOG_STORE_SECRET_KEY:
LOG_STORE_GENERATIONS_BUCKET:

All the above mentioned are S3 Compatible document storages and interoperable with S3 API. You need to generate the Access Key and Secret Key from the respective providers.

Notes on Cache If CACHE_STORE is set as redis, a redis instance will also get deployed in the cluster. If you are using custom redis, then leave it blank.

The following values are mandatory

REDIS_URL:
REDIS_TLS_ENABLED:

REDIS_URL defaults to redis://redis:6379 and REDIS_TLS_ENABLED defaults to false.

Notes on Analytics Store This is hosted in Portkey’s control plane and these credentials will be shared by the Portkey team.

The following are mandatory and are shared by the Portkey Team.

PORTKEY_CLIENT_AUTH:
ORGANISATIONS_TO_SYNC:

​
Step 3: Deploy using Helm Charts

Navigate to the directory containing your Helm chart and run the following command to deploy the application:

helm install portkey-gateway ./helm/enterprise --namespace portkeyai --create-namespace

This command installs the Helm chart into the portkeyai namespace.

​
Step 4: Verify the Deployment

Check the status of your deployment to ensure everything is running correctly:

kubectl get pods -n portkeyai

​
Step 5: Port Forwarding (Optional)

To access the service over internet, use port forwarding:

kubectl port-forward  -n portkeyai 443:8787

Replace <pod-name> with the name of your pod.

​
Uninstalling the Deployment

If you need to remove the deployment, run:

helm uninstall portkey-app --namespace portkeyai

This command will uninstall the Helm release and clean up the resources.

​
Network Configuration

​
Step 1: Allow access to the service

To make the service accessible from outside the cluster, define a Service of type LoadBalancer in your values.yaml or Helm templates. Specify the desired port for external access.

service:
  type: LoadBalancer
  port:
  targetPort: 8787

Replace <desired_port> with the port number for external access with the port the application listens on internally.

​
Step 2: Ensure Outbound Network Access

By default, Kubernetes allows full outbound access, but if your cluster has NetworkPolicies that restrict egress, configure them to allow outbound traffic.

Example NetworkPolicy for Outbound Access:

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: allow-all-egress
  namespace: portkeyai
spec:
  podSelector: {}
  policyTypes:
  - Egress
  egress:
  - to:
    - ipBlock:
        cidr: 0.0.0.0/0

This allows the gateway to access LLMs hosted within your VPC and outside as well. This also enables connection for the sync service to the Portkey Control Plane.

​
Step 3: Configure Inbound Access for Portkey Control Plane

Ensure the Portkey control plane can access the service either over the internet or through VPC peering.

Over the Internet:

  • Ensure the LoadBalancer security group allows inbound traffic on the specified port.
  • Document the public IP/hostname and port for the control plane connection.

Through VPC Peering:

Set up VPC peering between your AWS account and the control plane’s AWS account. Requires manual setup by Portkey Team.

​
Required Permissions

To ensure the smooth operation of Portkey AI in your private cloud deployment on AWS, specific permissions are required based on the type of log store you are using. Below are the details for S3 or MongoDB compliant databases.

S3 Bucket

If using S3 as the log store, the following IAM policy permissions are required:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:ListBucket",
                "s3:GetObject",
                "s3:PutObject",
                "s3:DeleteObject"
            ],
            "Resource": [
                "arn:aws:s3:::YOUR_BUCKET_NAME",
                "arn:aws:s3:::YOUR_BUCKET_NAME/*"
            ]
        }
    ]
}

Please replace YOUR_BUCKET_NAME with your actual bucket name.

MongoDB Compliant Database

If using a MongoDB compliant database, ensure the AI Gateway has access to the database. The database user should have following role:

{
    "roles": [
        {
            "role": "readWrite",
            "db": "YOUR_DATABASE_NAME"
        }
    ]
}

The readWrite role provides the necessary read and write access to the specified database. Please replace YOUR_DATABASE_NAME with your actual database name.

Cache Store - Redis

The Portkey Gateway image ships with a redis installed. You can choose to use the inbuilt redis or connect to an outside Redis instance.

  1. Redis as Part of the Image: No additional permissions or networking configurations are required.
  2. Separate Redis Instance: The gateway requires permissions to perform read and write operations on the Redis instance. The redis connections can be configured with or without TLS.
