MongoDB Enterprise Kubernetes Operator kubectl and oc Installation Settings

To provide optional settings, edit the YAML file that corresponds to your deployment type in the directory where you cloned the Kubernetes Operator repository:

Vanilla Kubernetes using kubectl: mongodb-enterprise.yaml
OpenShift using oc: mongodb-enterprise-openshift.yaml

If the setting that you want to add doesn't exist in the YAML file, add it as a new array of key-value pair mappings in the spec.template.spec.containers.name.env. collection:

Set the value of the spec.template.spec.containers.name.env.name key to the setting's name.
Set the value of the spec.template.spec.containers.name.env.value key to the setting's value.

To fill in values for container images, see Container Images.

MDB_APPDB_ASSUME_OLD_FORMAT

In Kubernetes Operator 1.20, the container registry changed for the application database image and the images use a new tag suffix. When you upgrade the Kubernetes Operator, the Kubernetes Operator automatically updates the earlier suffix, -ent, for all images that reference the new container registry to -ubi8 or the suffix set in MDB_IMAGE_TYPE or mongodb.imageType.

For example, the Kubernetes Operator changes quay.io/mongodb/mongodb-enterprise-server:4.4.5-ent to quay.io/mongodb/mongodb-enterprise-server:4.4.5-ubi8.

To stop the Kubernetes Operator from automatically updating the suffix, set MDB_APPDB_ASSUME_OLD_FORMAT or mongodb.appdbAssumeOldFormat to true. For example, you might want to stop the automatic suffix change if you're mirroring this image from your own repository.

The default value is false, which automatically updates the image suffix.

11              value: 3

WATCH_NAMESPACE

Namespaces that the Kubernetes Operator watches for MongoDB resource changes. If this namespace differs from the default, ensure that the Kubernetes Operator ServiceAccount can access this namespace.

To watch all namespaces, specify * and assign the ClusterRole to the mongodb-enterprise-operator ServiceAccount that you use to run the Kubernetes Operator.
To watch a subset of all namespaces, specify them in a comma-separated list, escape each comma with a backslash, and surround the list in quotes, such as "operator.watchNamespace=ns1\,ns2".

Watching a subset of namespaces is useful in deployments where a single Kubernetes Operator instance watches a different cluster resource type. For example, you can configure the Kubernetes Operator to watch MongoDB resources in one subset of namespaces, and to watch MongoDBMultiCluster resources in another subset of namespaces. To avoid race conditions during resource reconciliation, for each custom resource type that you want the Kubernetes Operator to watch, ensure that you set scope to a distinct subset of namespaces.

Important

To deploy Ops Manager and MongoDB resources to one or more namespaces other than the one where you deploy the Kubernetes Operator, see Set Scope for MongoDB Enterprise Kubernetes Operator Deployment for values you must use and additional steps you might have to perform.

The default value is <metadata.namespace>.
