vespa-k8s-cluster's Introduction

vespa-k8s-cluster

This repo is a small setup for running a test vespa cluster on kubernetes with kind for testing slightly more complex Vespa cluster setup.

It's main purpose is to serve as a test cluster for the vscode-vespa plugin.

Requirements

kind
(optional) k9s - Good tool for managing your K8s cluster
(optional) vscode-vespa - Vscode plugin to run Vespa YQL queries against your vespa clusters.

Create the k8s cluster

The kind-config.yaml sets up 5 node cluster with one controller and 4 worker nodes.

K8S_NAME="vespa-test-cluster"
# If cluster already exist just delet it :-)
kind delete cluster --name "${K8S_NAME}"
kind create cluster \
    --name "${K8S_NAME}" \
    --config kind-config.yaml

Deploy and start the Vespa Cluster

kubectl apply -f k8s/

forward ports needed

The vscode-vespa plugin needs to access the 19071, 19050 and 8080 ports of the vespa config nodes.

./k8s-forward-ports.sh

Delete and cleanup

kubectl delete -f k8s/

# Get the PVCs and delete them as they are persisted across K8s restarts.
kubectl get pvc
kubectl delete pvc ...

Deploy vespa application

cd /path/to/the/vespa-application

# Creates target/application.zip
mvn -DskipTests=true package

# Deploy the application
curl --header Content-Type:application/zip --data-binary @target/application.zip \
  localhost:19071/application/v2/tenant/default/prepareandactivate
