Install the MongoDB Enterprise Kubernetes Operator

On this page

Prerequisites and Considerations

Before you install the Kubernetes Operator, make sure you plan for your installation:

Note

This tutorial presumes some knowledge of Kubernetes and links to relevant Kubernetes documentation. If you are unfamiliar with Kubernetes, please review that documentation first.

Install with Kubernetes

The installation procedure varies based on how you want to configure your environment:

Use the same namespace throughout

The following examples assume that you created a namespace using the default Kubernetes Operator namespace of mongodb. If you specified a different label for your namespace when you created it, change all values for metadata.namespace to that namespace.

To change the label for the namespace for the following deployment to production, edit all values for metadata.namespace in mongodb-enterprise.yaml:

copy 
##---
# Source: mongodb-enterprise-operator/templates/serviceaccount.yaml
---
apiVersion: v1
kind: ServiceAccount
metadata:
  name: mongodb-enterprise-operator
  namespace: production
##---
# Source: mongodb-enterprise-operator/templates/operator.yaml
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: mongodb-enterprise-operator
  namespace: production

---
# Example truncated
---
...

Install the CustomResourceDefinitions for MongoDB deployments using the following kubectl command:

Invoke the following kubectl command:

copy 
kubectl apply -f crds.yaml
3

Optional: Customize the Kubernetes Operator YAML before installing it.

To learn about optional Kubernetes Operator installation settings, see Operator kubectl and oc Installation Settings.

4

Install the Kubernetes Operator using the following kubectl command:

Invoke the following kubectl command:

copy 
kubectl apply -f mongodb-enterprise.yaml

Use the MongoDB Helm Charts for Kubernetes.

You can install the Kubernetes Operator with Helm 3.

1

Add the MongoDB Helm Charts for Kubernetes repository to Helm.

copy 
helm repo add mongodb https://mongodb.github.io/helm-charts
2

Install the Kubernetes Operator:

Install MongoDB Helm Charts for Kubernetes. The following command installs the CustomResourceDefinitions and the Kubernetes Operator in the current namespace named default. By default, the Kubernetes Operator uses the default namespace.

copy 
helm install enterprise-operator mongodb/enterprise-operator

The following command installs the Kubernetes Operator in the mongodb namespace with the optional --create-namespace option.

copy 
helm install enterprise-operator mongodb/enterprise-operator \
  --namespace mongodb \
  --create-namespace

To learn about optional Kubernetes Operator installation settings, see Operator Helm Installation Settings.

Use the MongoDB Helm Charts for Kubernetes.

You can install the Kubernetes Operator with Helm 3.

To install the Kubernetes Operator on a host not connected to the Internet:

1

Use docker to request the files on a host connected to the Internet.

copy

  --set registry.pullPolicy='IfNotPresent'

Install with OpenShift

The installation procedure varies based on how you want to configure your environment:

Use the same namespace throughout

The following examples assume that you created a namespace using the default Kubernetes Operator namespace of mongodb. If you specified a different label for your namespace when you created it, change all values for metadata.namespace to that namespace.

To change the label for the namespace for the following deployment to production, edit all values for metadata.namespace in mongodb-enterprise-openshift.yaml:

copy 
##---
# Source: mongodb-enterprise-operator/templates/serviceaccount.yaml
---
apiVersion: v1
kind: ServiceAccount
metadata:
  name: enterprise-operator
  namespace: production
##---
# Source: mongodb-enterprise-operator/templates/operator.yaml

  --set registry.imagePullSecrets='<openshift-pull-secret>' \
  --values https://raw.githubusercontent.com/mongodb/helm-charts/main/charts/enterprise-operator/values-openshift.yaml

Use the values-openshift.yaml settings, registry.pullPolicy=IfNotPresent, and registry.imagePullSecrets=<openshift-pull-secret>. To learn about optional Kubernetes Operator installation settings, see Operator Helm Installation Settings.

Verify the Installation

To verify that the Kubernetes Operator installed correctly, run the following command and verify the output:

copy 
kubectl describe deployments mongodb-enterprise-operator -n <metadata.namespace>

By default, deployments exist in the mongodb namespace. If the following error message appears, ensure you use the correct namespace:

copy 
Error from server (NotFound): deployments.apps "mongodb-enterprise-operator" not found

To troubleshoot your Kubernetes Operator, see Review Logs from the Kubernetes Operator and other troubleshooting topics.

Important

If you need to remove the Kubernetes Operator or the namespace, you first must remove MongoDB resources.

Install a Specific Daily Build with Helm

MongoDB rebuilds Kubernetes Operator images every day to integrate the latest security and OS updates.

By default, helm installs the latest build for the version of the Kubernetes Operator you specify.

To install an earlier build, specify the build ID as a parameter with --set build=<build-id>. Build IDs are always in the format -b<YYYYMMDD>T000000Z, where <YYYYMMDD> is the date that the build you want to use was created.

Example

This example shows how to install the Kubernetes Operator with the latest image:

helm install enterprise-operator mongodb/enterprise-operator

This example shows how to install the Kubernetes Operator with the image created at midnight on February 5th, 2021:

helm install enterprise-operator mongodb/enterprise-operator \
  --set build=-b20210205T000000Z

Note

MongoDB recommends using the default (latest) build.
