Prepare for NAI Deployment

GA Software with NAI v2.7.0

In this lab, we will deploy GA version of the following software to test the following:

  • Nutanix Enterprise AI

    • Unified Endpoints - multiple endpoints for HA and token-based rate limiting
    • Providers - Add remote endpoints from providers to utilize their models in Nutanix Enterprise AI workloads.

Info

Changes in NAI v2.7.0

  • Kserve is of at least of v0.15.0
  • Cert-manager is at least of v1.17.2
  • OpenTelemetry operator is at least of v0.102.0
  • Envoy Gateway is at least of v1.7.0
  • Prometheus Monitoring is at least of 78.4.0

Enable Pre-requisite Applications

Prometheus and Cert Manager

The following pre-requisite applications will be enabled on NKP GUI:

Note

In this lab, we will be using the Management Cluster Workspace to deploy our Nutanix Enterprise AI (NAI)

However, in a customer environment, it is recommended to use a separate workload NKP cluster.

Info

The helm charts and the container images for these applications are stored in internal Harbor registry. These images got uploaded to Harbor at the time of install NKE in this section.

Search and Enable the following applications: follow this order to install dependencies for NAI application

  1. In the NKP GUI, Go to Clusters
  2. Click on Management Cluster Workspace

  3. Go to Applications to search and enable the following:

    • Prometheus Monitoring : version 78.4.0 or higher with the following Values configuration 

      alertmanager:
  enabled: false
grafana:
  enabled: false
prometheus:
  enabled: false
kubeStateMetrics:
  enabled: false
kubernetesServiceMonitors:
  enabled: false
prometheus-node-exporter.kubeRBACProxy:
  kubeRBACProxy:
    enabled: true

    • Cert-manager- v1.17.2

      The following application are pre-installed on NKP cluster with Pro license

      • Cert Manager v1.17.2 or higher

      Check if Cert Manager is installed (pre-installed on NKP cluster if license is installed)

      kubectl get deploy -n cert-manager

      $ kubectl get deploy -n cert-manager

NAME                      READY   UP-TO-DATE   AVAILABLE   AGE
cert-manager              1/1     1            1           145m
cert-manager-cainjector   1/1     1            1           145m
cert-manager-webhook      1/1     1            1           145m

      If not installed, use or NKP Applications GUI to install it

      The following command can also be used to install Cert-manager

      kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.17.2/cert-manager.yaml

The following pre-requisite applications will be enabled from the command line on the jumphost VM.

Install SSL Certificate and Gateway Elements

In this section we will install SSL Certificate to access the NAI UI. This is required as the endpoint will only work with a ssl endpoint with a valid certificate.

NAI UI is accessible using the Envoy Ingress Gateway.

Optional and manual - using Public Certificate Authority (CA)

If an organization generates certificates using a different mechanism then obtain the certificate + key and create a kubernetes secret manually using the following command:

  1. Create the certificate from the files (generated using certbot or provided to you)

    kubectl -n nai-system create secret tls nai-cert \
--cert=path/to/nai.crt \
--key=path/to/nai.key

  2. Combine the certificates to get the certificate bundle

    cat server.crt intermediate.crt > tls-bundle.crt

  3. Create a kubernetes secret in the nai-system namespace to use during NAI install

      kubectl secret tls nai-cert \
  --cert=tls-bundle.crt \
  --key=server.key \
  -n nai-system

  4. Patch the Envoy gateway with the nai-cert certificate details

    kubectl patch gateway nai-ingress-gateway -n nai-system --type='json' -p='[{"op": "replace", "path": "/spec/listeners/1/tls/certificateRefs/0/name", "value": "nai-cert"}]'
Optional to automate - using Public Certificate Authority (CA) and Cert Manager

Using Cert Manager to manage the Public Certificate Authority (CA) for NAI SSL Certificate is also a possiblity.

At a high level (Cloudflare Example):

  1. Get a API key from DNS provider woth Edit Zone rights

  2. Create a Kubernetes Secret from the API key

    apiVersion: v1
kind: Secret
metadata:
  name: cloudflare-api-token-secret
  namespace: harbor
type: Opaque
stringData:
  api-token: _YOUR_CLOUDFLARE_API_TOKEN_HERE

    apiVersion: v1
kind: Secret
metadata:
  creationTimestamp: null
  name: route53-api-token-secret
  namespace: cert-manager
data:
  access-key-id: "_YOUR_AWS_ACCESS_KEY_ID"
  secret-access-key: "_YOUR_AWS_SECRET_KEY_ID"

  3. Create a ClusterIssuer with Cert Mangager/Let's Encrypt - Configure cert-manager to use DNS-01 challenge with Cloudflare for automatic certificate issuance.

    apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: letsencrypt-cloudflare
  namespace: cert-manager
spec:
  acme:
    email: _YOUR_DOMAIN_OWNER_EMAIL_ADDRESS
    server: https://acme-v02.api.letsencrypt.org/directory
    privateKeySecretRef:
      name: letsencrypt-cloudflare-account-key
    solvers:
    - dns01:
        cloudflare:
          apiTokenSecretRef:
            name: cloudflare-api-token-secret
            key: api-token

    apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: letsencrypt-cloudflare
spec:
  acme:
    email: _YOUR_DOMAIN_OWNER_EMAIL_ADDRESS
    server: https://acme-v02.api.letsencrypt.org/directory
    privateKeySecretRef:
      name: nai-letsencrypt-cluster
    solvers:
      - dns01:
          route53:
            region: us-east-1
            accessKeyIDSecretRef:
              name: route53-api-token-secret
              key: access-key-id
            secretAccessKeySecretRef:
              name: route53-api-token-secret
              key: secret-access-key
            hostedZoneID: _HOSTED_ZONE_ID

  4. Create the ingress resource certificate using the following command:

    cat << EOF | k apply -f -
apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
  name: nai-cert
  namespace: nai-system
spec:
  issuerRef:
    name: letsencrypt-cloudflare
    kind: ClusterIssuer
  secretName: nai-cert
  commonName: nai.domain.com
  dnsNames:
  - nai.domain.com
EOF

  5. Patch the Envoy gateway with the nai-cert certificate details

    kubectl patch gateway nai-ingress-gateway -n nai-system --type='json' -p='[{"op": "replace", "path": "/spec/listeners/1/tls/certificateRefs/0/name", "value": "nai-cert"}]'

The following steps show how cert-manager can be used to generate a self signed certificate using the default selfsigned-issuer present in the cluster for the purposes of the lab.

  1. Get the NAI UI ingress gateway host using the following command:

    NAI_UI_ENDPOINT=$(kubectl get svc -n envoy-gateway-system -l "gateway.envoyproxy.io/owning-gateway-name=nai-ingress-gateway,gateway.envoyproxy.io/owning-gateway-namespace=nai-system" -o jsonpath='{.items[0].status.loadBalancer.ingress[0].ip}')

  2. Get the value of NAI_UI_ENDPOINT environment variable

    echo $NAI_UI_ENDPOINT

    10.x.x.216

  3. We will use the command output e.g: 10.x.x.216 as the IP address for NAI as reserved in this section

  4. Construct the FQDN of NAI UI using nip.io and we will use this FQDN as the certificate's Common Name (CN).

    nai.${NAI_UI_ENDPOINT}.nip.io

    nai.10.x.x.216.nip.io

  5. Create the ingress resource certificate using the following command:

    cat << EOF | k apply -f -
apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
  name: nai-cert
  namespace: nai-system
spec:
  issuerRef:
    name: selfsigned-issuer
    kind: ClusterIssuer
  secretName: nai-cert
  commonName: nai.${NAI_UI_ENDPOINT}.nip.io
  dnsNames:
  - nai.${NAI_UI_ENDPOINT}.nip.io
  ipAddresses:
  - ${NAI_UI_ENDPOINT}
EOF

  6. Patch the Envoy gateway with the nai-cert certificate details

    kubectl patch gateway nai-ingress-gateway -n nai-system --type='json' -p='[{"op": "replace", "path": "/spec/listeners/1/tls/certificateRefs/0/name", "value": "nai-cert"}]'

  7. Create EnvoyProxy

    k apply -f -<<EOF
apiVersion: gateway.envoyproxy.io/v1alpha1
kind: EnvoyProxy
metadata:
  name: envoy-service-config
  namespace: nai-system
spec:
  provider:
    type: Kubernetes
    kubernetes:
      envoyService:
        type: LoadBalancer
EOF

  8. Patch the nai-ingress-gateway resource with the new EnvoyProxy details

    kubectl patch gateway nai-ingress-gateway -n nai-system --type=merge \
-p '{
    "spec": {
        "infrastructure": {
            "parametersRef": {
                "group": "gateway.envoyproxy.io",
                "kind": "EnvoyProxy",
                "name": "envoy-service-config"
            }
        }
    }
}'

Accessing the UI

  1. In a browser, open the following URL to connect to the NAI UI

    https://nai.10.x.x.216.nip.io

  2. Use the ${NAI_USER} and ${NAI_TEMP_PASS} values set in ${ENVIRONMENT}-values.yaml files during helm installation of NAI v.2.4.0

  3. Change the password for the admin user

  4. Login using admin user and password.

Download Model

We will download and user llama3 8B model which we sized for in the previous section.

  1. In the NAI GUI, go to Models
  2. Click on Import Model from Hugging Face
  3. Choose the meta-llama/Meta-Llama-3.1-8B-Instruct model

  4. Input your Hugging Face token that was created in the previous section and click Import

  5. Provide the Model Instance Name as Meta-Llama-3.1-8B-Instruct and click Import

  6. Go to VSC Terminal to monitor the download

Create and Test Inference Endpoint

In this section we will create an inference endpoint using the downloaded model.

  1. Navigate to Inference Endpoints menu and click on Create Endpoint button

  2. Fill the following details:

    • Endpoint Name: llama-8b
    • Model Instance Name: Meta-LLaMA-8B-Instruct
    • Use GPUs for running the models : Checked
    • No of GPUs (per instance):
    • GPU Card: NVIDIA-L40S (or other available GPU)
    • No of Instances: 1
    • API Keys: Create a new API key or use an existing one

  3. Click on Create

  4. Monitor the nai-admin namespace to check if the services are coming up

    kubens nai-admin
kubectl get po,deploy

    kubens nai-admin
get po,deploy
NAME                                                     READY   STATUS        RESTARTS   AGE
pod/llama8b-predictor-00001-deployment-9ffd786db-6wkzt   2/2     Running       0          71m

NAME                                                 READY   UP-TO-DATE   AVAILABLE   AGE
deployment.apps/llama8b-predictor-00001-deployment   1/1     1            0           3d17h

  5. Check the events in the nai-admin namespace for resource usage to make sure all 

    kubectl get events -n nai-admin --sort-by='.lastTimestamp' | awk '{print $1, $3, $5}'

    $ kubectl get events -n nai-admin --sort-by='.lastTimestamp' | awk '{print $1, $3, $5}'

    kubectl get isvc

    kubectl get isvc

Troubleshooting Endpoint ISVC

TGI Imange and Self-signed Certificates

Only follow this procedure if this isvc is not starting up.

KNative Serving Image Tag Checking

From testing, we have identified that KServe module is making sure that there are no container image tag discrepencies, by pulling image using SHA digest. This is done to avoid pulling images that are updated without updating the tag.

We have avoided this behavior by patching the config-deployment config map in the knative-serving namespace to skip image tag checking. Check this Prepare for NAI Deployment sectionfor more details.

kubectl patch configmap  config-deployment -n knative-serving --type merge -p '{"data":{"registries-skipping-tag-resolving":"${REGISTRY}"}'

If this procedure was not followed, then the isvc will not start up.

  1. If the isvc is not coming up, then explore the events in nai-admin namespace.

    kubens nai-admin
kubectl get isvc
kubectl get events  --sort-by='.lastTimestamp'

    $ kubectl get isvc

NAME      URL                                          READY   PREV   LATEST   PREVROLLEDOUTREVISION   LATESTREADYREVISION       AGE
llama8b   http://llama8b.nai-admin.svc.cluster.local   False

$ kubectl get events --sort-by='.lastTimestamp'

Warning   InternalError         revision/llama8b-predictor-00001   Unable to fetch image "harbor.10.x.x.134.nip.io/nkp/nutanix/nai-tgi:2.3.1-825f39d": failed to resolve image to digest: 
Get "https://harbor.10.x.x.134.nip.io/v2/": tls: failed to verify certificate: x509: certificate signed by unknown authority

    The temporary workaround is to use the TGI images SHA signature from the container registry.

    This site will be updated with resolutions for the above issues in the future.

  2. Note the above TGI image SHA digest from the container registry.

    docker pull ${REGISTRY}/nutanix/nai-tgi:${NAI_TGI_RUNTIME_VERSION}

    docker pull harbor.10.x.x.134.nip.io/nkp/nutanix/nai-tgi:2.3.1-825f39d

2.3.1-825f39d: Pulling from nkp/nutanix/nai-tgi
Digest: sha256:2df9fab2cf86ab54c2e42959f23e6cfc5f2822a014d7105369aa6ddd0de33006
Status: Image is up to date for harbor.10.x.x.134.nip.io/nkp/nutanix/nai-tgi:2.3.1-825f39d
harbor.10.x.x.134.nip.io/nkp/nutanix/nai-tgi:2.3.1-825f39d

  3. The SHA digest will look like the following:

    TGI image SHA digest will be different for different environments
    sha256:2df9fab2cf86ab54c2e42959f23e6cfc5f2822a014d7105369aa6ddd0de33006

  4. Create a copy of the isvc manifest

    kubectl get isvc llama8b -n nai-admin -o yaml > llama8b.yaml

  5. Edit the isvc

    kubectl edit isvc llama8b -n nai-admin

  6. Search and replace the image tag with the SHA digest from the TGI image.

    <snip>

env:
- name: STORAGE_URI
  value: pvc://nai-c34d8d58-d6f8-4cb4-94e4-28-pvc-claim/model-files
  image: harbor.10.x.x.134.nip.io/nkp/nutanix/nai-tgi:2.3.1-825f39d

<snip>
    7. After replacing the image's SHA digest, the image value should look as follows: 

    <snip>

env:
- name: STORAGE_URI
  value: pvc://nai-c34d8d58-d6f8-4cb4-94e4-28-pvc-claim/model-files
  image: harbor.10.x.x.134.nip.io/nkp/nutanix/nai-tgi@sha256:2df9fab2cf86ab54c2e42959f23e6cfc5f2822a014d7105369aa6ddd0de33006

<snip>

  7. Save the isvc configuration by writing the changes to the file and exiting the vi editor using :wq! key combination.

  8. Verify that the isvc is running

    kubens nai-admin
kubectl get isvc

    $ kubectl get isvc

NAME      URL                                          READY   PREV   LATEST   PREVROLLEDOUTREVISION   LATESTREADYREVISION       AGE
llama8b   http://llama8b.nai-admin.svc.cluster.local   True           100                              llama8b-predictor-00001   3d17h

This should resolve the issue the issue with the TGI image.
