MongoDB Enterprise Kubernetes Operator Helm Installation Settings

To provide optional settings, pass them to Helm using the --set argument. Use the following files that list value settings for your deployment type:

Vanilla Kubernetes: values.yaml
OpenShift: values-openshift.yaml

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

Run the command as in the following example and the options that you specified will be passed to your configuration:

helm upgrade enterprise-operator mongodb/enterprise-operator \
  --set registry.pullPolicy='IfNotPresent'

# If running OpenShift (Cloud, Minishift, etc.), set this to true.
managedSecurityContext: true

mongodb.appdbAssumeOldFormat

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.

mongodb:
   appdbAssumeOldFormat: false

mongodb.imageType

The suffix of the application database image.

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.

The default is ubi8. We recommend using only ubi images for consistency, but if you need to, you can change this setting to ubuntu2204.

mongodb:
   imageType: ubi8

multiCluster.clusterClientTimeout

Time, in seconds, the Kubernetes Operator attempts to connect to a cluster's Kubernetes API server endpoint. This timeout is set for all Kubernetes clusters in multi-Kubernetes cluster MongoDB deployments. If the Kubernetes Operator doesn't get a response from the Kubernetes API server within the specified time, it logs the cluster's status as "unhealthy". To learn more, see Troubleshooting Kubernetes Clusters.

The default value is 10.

multiCluster:
   clusterClientTimeout: 10

namespace

namespaces in which you want to deploy the Kubernetes Operator.

To use a namespace other than the default, specify the namespace in which you want to deploy the Kubernetes Operator.

The default value is mongodb.

# Name of the Namespace to use
namespace: mongodb

needsCAInfrastructure

Determines whether Kubernetes creates a ClusterRole that allows the Kubernetes Operator to sign TLS certificates using the certificates.k8s.io API.

needsCAInfrastructure: true

The default value is true.

operator.deployment_name

Name of the Kubernetes Operator container.

The default value is mongodb-enterprise-operator.

operator:
   deployment_name: mongodb-enterprise-operator

operator.env

Label for the Kubernetes Operators deployment environment. This value affects the default timeouts and the logging level and format:

If the value is	Log Level is set to	Log Format is set to
`dev`	debug	text
`prod`	info	json

The default value is prod.

operator:
   # Execution environment for the operator, dev or prod.
   # Use dev for more verbose logging
   env: prod

operator.mdbDefaultArchitecture

Determines the container architecture used by all your deployments:

The default non-static containers that download the MongoDB binary at runtime, or
Static Containers (Public Preview) that are immutable at runtime.

The default is non-static.

To enable static containers, set to static.

Note

This setting applies to all your deployments, including existing deployments. To enable static containers for a single deployment, use metadata.annotations.mongodb.com/v1.architecture in the MongoDB resource instead.

operator.mdbDefaultArchitecture: static

operator.name

Name that Kubernetes assigns to Kubernetes Operator objects, such as Deployments, ServiceAccounts, Roles, and Pods.

This value also corresponds to the name of the container registry where the Kubernetes Operator is located.

The default value is mongodb-enterprise-operator.

operator:
   name: mongodb-enterprise-operator

operator.maxConcurrentReconciles

The maximum number of concurrent reconciliatios the Kubernetes Operator can perform. It sets MaxConcurrentReconciles. To learn more, see the Kubernetes Operator Deploy Multiple MongoDB Replica Sets.

Example

operator:
  # Control how many reconciles can be performed in parallel.
  # Increasing the number of concurrent reconciliations decreases the time needed to reconcile all watched resources,
  # but it might result in request load spikes and increased load on the Ops Manager API, and the Kubernetes API server generally.
  maxConcurrentReconciles: 10

operator.vaultSecretBackend.enabled

Determines whether the Kubernetes Operator stores secrets in HashiCorp Vault. To learn more, see Set the Secret Storage Tool. If you are using TLS with Vault, you must also specify operator.vaultSecretBackend.tlsSecretRef.

The default value is false.

operator:
   # Set the following setting to "true" so that the MongoDB Kubernetes Operator stores secrets in Vault.
   vaultSecretBackend: false

operator.vaultSecretBackend.tlsSecretRef

Required if you are using TLS with Vault. The TLS secret used in your Vault configuration that contains a ca.crt entry. The content of the ca.crt entry must match the certificate of the CA used to generate the Vault TLS certificates. The Kubernetes Operator stores this TLS secret in its secret storage tool. To learn more, see Configure Secret Storage. Requires that operator.vaultSecretBackend.enabled is set to true.

operator:
   vaultSecretBackend: true
      tlsSecretRef: "vault-tls-secret"

operator.version

Version of the Kubernetes Operator that you want to deploy.

The default value is 1.26.

operator:
   version: 1.26

operator.watchNamespace

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>.

# Watch one namespace
helm install enterprise-operator mongodb/enterprise-operator \
   --set operator.watchNamespace='namespace-to-watch' <...>

# Watch both namespace-a and namespace-b
helm install enterprise-operator mongodb/enterprise-operator \
   --set operator.watchNamespace="namespace-a\,namespace-b"

# Operator with name `mongodb-enterprise-operator-qa-envs` will
# watch ns-dev, ns-qa and ns-uat namespaces
helm install mongodb-enterprise-operator-qa-envs mongodb/enterprise-operator \
   --set operator.watchNamespace="ns-dev\,ns-qa\,ns-uat"

# Operator with name `mongodb-enterprise-operator-staging` will
# watch ns-staging and ns-pre-prod
helm install mongodb-operator helm-chart --set operator.watchNamespace="ns-staging\,ns-pre-prod" mongodb-enterprise-operator-staging

operator.watchedResources

Custom resources that the Kubernetes Operator watches.

The Kubernetes Operator installs the CustomResourceDefinitions for and watches only the resources you specify.

The Kubernetes Operator accepts the following values:

Value	Description
`mongodb`	Install the CustomResourceDefinitions for database resources and watch those resources.
`mongodbusers`	Install the CustomResourceDefinitions for MongoDB user resources and watch those resources.
`opsmanagers`	Install the CustomResourceDefinitions for Ops Manager resources and watch those resources.

operator:
   watchedResources:
      - mongodbusers
      - mongodb
      - opsmanagers

The default value is mongodb-enterprise-ops-manager.

opsManager:
   name: mongodb-enterprise-ops-manager

registry.agent

URL for the Quay container registry for MongoDB images. The agent.name gets appended and sets the MDB_AGENT_IMAGE_REPOSITORY environment variable to the full URL from which the StatefulSet downloads the MongoDB Agent image for database deployments. To learn more, see Container Images.

The default value is quay.io/mongodb.

registry:
agent: quay.io/mongodb/

registry.appDb

If you use the Kubernetes Operator to deploy MongoDB resources to multiple namespaces or with a cluster-wide scope, create the secret only in the namespace where you installed the Kubernetes Operator. The Kubernetes Operator synchronizes the secret across all watched namespaces.

registry:
# Specify the secret in the ``imagePullSecrets`` setting. If you
# use the MongoDB Kubernetes Operator to deploy MongoDB resources
# into multiple namespaces, create the secret only in the namespace
# where you installed the Operator. The Operator synchronizes
# the secret across all watched namespaces.
