Memgraph Standalone Kubernetes Helm Chart

A Helm Chart for deploying standalone Memgraph database on Kubernetes.

Installing the Memgraph Helm Chart

To install the Memgraph Helm Chart, follow the steps below:

helm install <release-name> memgraph/memgraph

Replace <release-name> with a name of your choice for the release.

Changing the default chart values

To change the default chart values, run the command with the specified set of flags:

helm install <resource-name> memgraph/memgraph --set <flag1>=<value1>,<flag2>=<value2>,...

Or you can modify a values.yaml file and override the desired values:

helm install <resource-name> memgraph/memgraph -f values.yaml

Configuration Options

The following table lists the configurable parameters of the Memgraph chart and their default values.

Parameter Description Default
image.repository Memgraph Docker image repository memgraph/memgraph
image.tag Specific tag for the Memgraph Docker image. Overrides the image tag whose default is chart version. "" (Defaults to chart's app version)
image.pullPolicy Image pull policy IfNotPresent
replicaCount Number of Memgraph instances to run. Note: no replication or HA support. 1
service.type Kubernetes service type NodePort
service.port Kubernetes service port 7687
service.targetPort Kubernetes service target port 7687
service.protocol Protocol used by the service TCP
service.annotations Annotations to add to the service {}
persistentVolumeClaim.storagePVC Enable persistent volume claim for storage true
persistentVolumeClaim.storagePVCClassName Storage class name for the persistent volume claim for storage. If not specified, default used. ""
persistentVolumeClaim.storagePVCSize Size of the persistent volume claim for storage 1Gi
persistentVolumeClaim.logPVC Enable persistent volume claim for logs true
persistentVolumeClaim.logPVCClassName Storage class name for the persistent volume claim for logs. If not specified, default used. ""
persistentVolumeClaim.logPVCSize Size of the persistent volume claim for logs 256Mi
memgraphConfig List of strings defining Memgraph configuration settings ["--also-log-to-stderr=true"]
statefulSetAnnotations Annotations to add to the stateful set {}
podAnnotations Annotations to add to the pod {}
resources CPU/Memory resource requests/limits. Left empty by default. {} (See note on uncommenting)
serviceAccount.create Specifies whether a service account should be created true
serviceAccount.annotations Annotations to add to the service account {}
serviceAccount.name The name of the service account to use. If not set and create is true, a name is generated. ""

Note: It's often recommended not to specify default resources and leave it as a conscious choice for the user. If you want to specify resources, uncomment the following lines in your values.yaml, adjust them as necessary:

resources:
  limits:
    cpu: "100m"
    memory: "128Mi"
  requests:
    cpu: "100m"
    memory: "128Mi"

The memgraphConfig parameter should be a list of strings defining the values of Memgraph configuration settings. For example, this is how you can define memgraphConfig parameter in your values.yaml:

memgraphConfig:
  - "--also-log-to-stderr=true"
  - "--log-level=TRACE"

For all available database settings, refer to the Configuration settings reference guide.
