Install Memgraph Kubernetes Operator

All described installation options will run the Operator inside the cluster.

Make sure to clone this repository with its submodule (helm-charts).

git clone --recurse-submodules git@github.com:memgraph/kubernetes-operator.git

Install K8 Resources

make deploy

This command will use operator's image from Memgraph's DockerHub and create all necessary Kubernetes resources for running an operator.

Verify Installation

Installation using any of the options described above will create a Kubernetes ServiceAccount, RoleBinding, Role, Deployment, and Pods all in the newly created namespace memgraph-operator-system. You can check your resources with:

kubectl get serviceaccounts -n memgraph-operator-system
kubectl get clusterrolebindings -n memgraph-operator-system
kubectl get clusterroles -n memgraph-operator-system
kubectl get deployments -n memgraph-operator-system
kubectl get pods -n memgraph-operator-system
kubectl get services -n memgraph-operator-system

CustomResourceDefinition memgraphhas.memgraph.com, whose job is to monitor CustomResource MemgraphHA, will also get created and you can verify this with:

kubectl get crds -A

Start Memgraph High Availability Cluster

We already provide a sample cluster in config/samples/memgraph_v1_ha.yaml. You only need to set your license information by creating a Kubernetes Secret containing licensing info. You can do this in a following way:

 kubectl create secret generic memgraph-secrets \
--from-literal=MEMGRAPH_ENTERPRISE_LICENSE="<YOUR_LICENSE_INFO>" \
--from-literal=MEMGRAPH_ORGANIZATION_NAME="<YOUR_ORGANIZATION_NAME>"

Start Memgraph HA cluster with kubectl apply -f config/samples/memgraph_v1_ha.yaml.

After approximately 60 seconds, you should be able to see instances in the output of kubectl get pods -A.

You can now find the URL of any coordinator instances by running e.g minikube service list and connect to see the state of the cluster by running show instances;: image

Clear Resources

kubectl delete -f config/samples/memgraph_v1_ha.yaml # For deleting cluster
kubectl delete pvc --all  # Or leave them if you want to use persistent storage
kubectl delete secret memgraph-secrets
make undeploy
