Neo4j 3 node cluster within 1 AKS cluster

Neo4j docs - https://neo4j.com/docs/operations-manual/current/kubernetes/quickstart-cluster/

az aks create -g drose-rg --name drose-demo2a --node-count=2 --os-sku Ubuntu
--load-balancer-sku Standard
--nodepool-name agentpool1 --node-osdisk-size 128 --node-vm-size Standard_D4ds_v5
--enable-addons azure-keyvault-secrets-provider --enable-oidc-issuer
--enable-workload-identity --generate-ssh-keys

az aks nodepool add --cluster-name drose-demo2a --name neo4jpool1 --resource-group drose-rg --mode User --node-count 3 --node-vm-size Standard_D4as_v5

Pre-req:

  • Azure resource group exists
  • AKS cluster exists (e.g. neo4j-aks-cluster)
  • Namespace within the AKS cluster exists (e.g neo4j)

Create Simple Standalone

# install the simple standalone chart
helm upgrade -i simplesa  neo4j/neo4j -f  simple_standalone.yaml
#look at the pods
kubectl get po
#describe the pods
kubectl describe po simplesa-0
kubectl get svc

Create Standalone with Bloom and GDS

# install the simple standalone chart
# populate licenses/gds.license and licenses/bloom.license with actual licenses
./createLicenseSecrets.sh
helm upgrade -i standalone  neo4j/neo4j -f  standalone.yaml
#look at the pods
kubectl get po
#describe the pods
kubectl describe po standalone-0

Create Load Balancer


kubectl apply -f standalone-lb.yaml
kubectl get svc 
#might say pending
kubectl describe svc standalone-lb 
#look for errors

Create the cluster

helm install server1 neo4j/neo4j --namespace neo4j -f neo4j-core-cluster.yaml
helm install server2 neo4j/neo4j --namespace neo4j -f neo4j-core-cluster.yaml
helm install server3 neo4j/neo4j --namespace neo4j -f neo4j-core-cluster.yaml

Cleanup

To uninstall, execute the following

helm uninstall server1 server2 server3

To fully remove all data and resources:

kubectl delete pvc --all --namespace neo4j
az aks delete --name neo4j-aks-cluster  --resource-group jhair-RG

3 Primary/node hybrid cluster with 1 Secondary/GDS (3 primary nodes, 1 secondary/GDS)

Pre-req:

  • Azure resource group exists

Create the cluster

Execute ./scripts/startall.sh The script will perform the following:

  • Create an AKS cluster (e.g. neo4j-aks-cluster)
  • Create a namespace within the AKS cluster (e.g. neo4j-hybrid)
  • Create a nodepool within the AKS cluster (e.g. neo4j)
  • Install the Neo4j services and pods
  • Create load balancers for the core DB and the GDS node

Cleanup

Execute ./scripts/stopall.sh

Deploy a single Neo4j cluster across multiple AKS clusters
