Upgrade the MongoDB Enterprise Kubernetes Operator

The following procedure outlines how to upgrade the Kubernetes Operator to its latest version.

Upgrade using Kubernetes

The following steps depend on how your environment is configured:

• Online using kubectl
• Online using Helm
• Offline using Helm and Docker

1

Upgrade the CustomResourceDefinitions for MongoDB deployments.

Invoke the following kubectl command:

copy

kubectl replace -f crds.yaml

2

Optional: Customize the Kubernetes Operator YAML before upgrading it.

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

3

If you are upgrading the Operator to version 1.13.0 or later, specify the spec.opsManager.configMapRef.name or the spec.cloudManager.configMapRef.name settings:

1. Open the MongoDB Database Resource Specification in the editor of your choice.
2. Add the value to the spec.opsManager.configMapRef.name setting or the spec.cloudManager.configMapRef.name setting and save the specification.

To learn more, see Changes to the MongoDB Resource.

4

Upgrade to the new version of the Kubernetes Operator.

Invoke the following kubectl command:

copy

kubectl apply -f mongodb-enterprise.yaml

1

If you are upgrading the Operator to version 1.13.0 or later, specify the spec.opsManager.configMapRef.name or the spec.cloudManager.configMapRef.name settings:

1. Open the MongoDB Database Resource Specification in the editor of your choice.
2. Add the value to the spec.opsManager.configMapRef.name setting or the spec.cloudManager.configMapRef.name setting and save the specification.

Optional: Customize your Helm Chart before upgrading it.

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

3

Upgrade the Kubernetes Operator.

Invoke the following helm command:

copy

helm upgrade enterprise-operator mongodb/enterprise-operator

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

1

If you are upgrading the Operator to version 1.13.0 or later, specify the spec.opsManager.configMapRef.name or the spec.cloudManager.configMapRef.name settings:

1. Open the MongoDB Database Resource Specification in the editor of your choice.
2. Add the value to the spec.opsManager.configMapRef.name setting or the spec.cloudManager.configMapRef.name setting and save the specification.
