MongoDB Kubernetes Operator Installation Using Helm

This guide walks you through the steps to install the MongoDB Kubernetes Operator in a specific namespace using Helm.

Prerequisites

Kubernetes Cluster: Ensure you have access to a running Kubernetes cluster.
Helm: Make sure Helm is installed. If not, you can install it following the Helm Installation Guide.
kubectl: Ensure kubectl is installed and properly configured to interact with your Kubernetes cluster.
MongoDB Helm Chart Repository: You need to add the MongoDB Helm chart repository.

Step-by-Step Installation

1. Add the MongoDB Helm Repository

Add the MongoDB chart repository to your Helm configuration:

helm repo add mongodb https://mongodb.github.io/helm-charts
helm repo update

2. Create a Namespace(optional)

Create the namespace where the MongoDB Operator will be installed:

kubectl create namespace <your-namespace>

Replace <your-namespace> with the desired namespace.

3. Install the MongoDB Operator

Install the MongoDB Kubernetes Operator into the specified namespace using Helm:

helm install mongodb-operator mongodb/community-operator \
    --namespace <your-namespace>

Parameters:

mongodb-operator: The Helm release name (changeable if desired).
mongodb/community-operator: The Helm chart name from the MongoDB repository.
--namespace <your-namespace>: Specifies the namespace for installation.

4. Verify the Installation

To confirm the installation, check the pods in the target namespace:

kubectl get pods -n <your-namespace>

5. Customizing the Installation

If customization is needed (e.g., resource limits, RBAC settings), create a values.yaml file with the desired configurations:

# values.yaml
namespace: <your-namespace>
resources:
  limits:
    cpu: 500m
    memory: 512Mi
  requests:
    cpu: 250m
    memory: 256Mi
rbac:
  create: true

Install the chart using the customized values.yaml file:

6. Troubleshooting

Check the Helm release in the specified namespace:

helm list -n <your-namespace>

Inspect the logs of the MongoDB Operator pod:

kubectl logs -n <your-namespace> <operator-pod-name>
