Install Seldon Core

Prerequisites

You will need:

• Git clone of Seldon Core

• A running Kubernetes cluster with kubectl authenticated

• seldon-core Python package (pip install seldon-core>=0.2.6.1)

• Helm client

Setup Cluster

kubectl create namespace seldon
kubectl config set-context $(kubectl config current-context) --namespace=seldon

Install Seldon Core

Follow the Seldon Core Install documentation.

kubectl create namespace seldon-system

If using Ambassador:

helm install seldon-core seldon-core-operator --repo https://storage.googleapis.com/seldon-charts --set ambassador.enabled=true --set usageMetrics.enabled=true --namespace seldon-system

If using Istio:

helm install seldon-core seldon-core-operator --repo https://storage.googleapis.com/seldon-charts --set istio.enabled=true --set usageMetrics.enabled=true --namespace seldon-system

Check all services are running before proceeding.

Wait for rollout to finish:

kubectl rollout status deploy/seldon-controller-manager -n seldon-system

Install Ingress

Ambassador

Ambassador install

Ambassador Edge Stack:

helm repo add datawire https://www.getambassador.io
helm repo update
helm install ambassador datawire/ambassador \
    --set image.repository=docker.io/datawire/ambassador \
    --set crds.keep=false \
    --namespace seldon-system

Ambassador API Gateway (Emissary Ingress):

helm repo add datawire https://www.getambassador.io
helm repo update
helm install ambassador datawire/ambassador \
    --set image.repository=docker.io/datawire/ambassador \
    --set crds.keep=false \

    --namespace seldon-system

Check all services are running before proceeding.

kubectl rollout status deployment.apps/ambassador

For Ambassador Edge Stack:

Note: Absent configuration, Ambassador Edge Stack will attempt to use TLS with a self-signed cert. Either set up TLS or ignore certificate validation (i.e. curl -k).

kubectl port-forward $(kubectl get pods -n seldon-system -l app.kubernetes.io/name=ambassador -o jsonpath='{.items[0].metadata.name}') -n seldon-system 8003:8443

For Ambassador API Gateway:

kubectl port-forward $(kubectl get pods -n seldon-system -l app.kubernetes.io/name=ambassador -o jsonpath='{.items[0].metadata.name}') -n seldon-system 8003:8080
