MongoDB Enterprise Kubernetes Database Helm Chart

A Helm Chart for deploying Mongo Databases with the MongoDB Enterprise Kubernetes Operator.

Prerequisites

This Chart creates MongoDB Kubernetes resources. You will need to have the MongoDB Enterprise Kubernetes Operator installed before deploying MongoDB resources with this Chart.

The installation of this Chart does not have prerequisites. However, in order to create a Mongo Database in your Kubernetes cluster, you'll need a Cloud Manager account or an Ops Manager installation.

Please look at the documentation for the MongoDB Enterprise Kubernetes Operator about how to do this.

Installing Enterprise Database Chart

You can install the MongoDB Enterprise Database Chart easily with:

helm install <resource-name> mongodb/enterprise-database

This operation will create a new MongoDB database in the current Namespace. Make sure that the Enterprise Operator can handle MongoDB resources in this Namespace. To set the mongodb namespace, for example:

helm install <resource-name> mongodb/enterprise-database --namespace mongodb [--create-namespace]

To install the Enterprise Operator in a namespace called mongodb; with the optional --create-namespace Helm will create the Namespace if it does not exist.

Configuring access to Cloud Manager

You need your Ops Manager or Cloud Manager stored in a Secret, please refer to the MongoDB Enterprise Kubernetes Operator docs about how to create them. Additionally, a ConfigMap will need to be created pointing at your Cloud Manager or Ops Manager installation.

Deploying a Sample Replica Set

With the Secret and ConfigMap created you will be able to create a new ReplicaSet with the following command:

helm install my-database mongodb/enterprise-database \
  --set manager.configMapRef=<project> \
  --set manager.credentials=<credentials>

In this case, you'll change <project> to the name of the ConfigMap you just created, and <credentials> to the Secret you also just created in the previous step. Both manager.configMap and manager.credentials are required!

Deploying a Sample Sharded Cluster

You can follow a similar approach to deploy a Sharded Cluster, setting the mongodb.type attribute to ShardedCluster.

helm install my-database mongodb/enterprise-database \
  --set mongodb.type=ShardedCluster \
  --set manager.configMapRef=<project> \
  --set manager.credentials=<credentials>

There are many options in values.yaml that can be set with --set commands. A reference to each one of these commands can be found in the documentation.
