Quick Start¶

Add the MongoDB Helm Charts for Kubernetes repository to Helm.¶

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

Install the MongoDB Enterprise Kubernetes Operator¶

To install the Kubernetes Operator with the Helm Chart, see the instructions in the repository.

Example

The following command installs the MongoDB Enterprise Kubernetes Operator in the mongodb namespace with the optional --create-namespace option. By default, Kubernetes Operator uses the default namespace.

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

Configure kubectl to default to your namespace.¶

If you haven’t already, run the following command to execute all kubectl commands in the namespace you created:

kubectl config set-context $(kubectl config current-context) --namespace=mongodb

Configure the Kubernetes Operator¶

1. Go to the Kubernetes Setup Page in the Cloud Manager UI.
2. Click Create New API Keys or Use Existing API Keys.
3. Complete the form. To learn more, see Programmatic Access to Cloud Manager.
4. Click Generate Key and YAML.

Copy and save the ConfigMap.¶

Copy and save the generated config-map.yaml file.

Example:

apiVersion: v1
kind: ConfigMap
metadata:
  name: my-project
  namespace: mongodb
data:
  baseUrl: https://cloud.mongodb.com

  projectName: my-project # this is an optional parameter
  orgId: 5ecd252f8c1a75033c74106c # this is a required parameter

To learn more, see the parameter descriptions.

Copy and save the Secret.¶

Copy and save the generated secret.yaml file.

Example:

apiVersion: v1
kind: Secret
metadata:
  name: organization-secret
  namespace: mongodb
stringData:
  user: <public_key>
  publicAPIKey: <private_key>

For security purposes, MongoDB Cloud Manager displays this file only once.

Apply the ConfigMap and Secret.¶

Run the following command:

kubectl apply -f secret.yaml -f config-map.yaml

Deploy the replica set resource.¶

1. Copy and save the following YAML file:

   copy

   apiVersion: mongodb.com/v1
   kind: MongoDB
   metadata:
     name: demo-mongodb-cluster-1
     namespace: mongodb
   spec:
     members: 3
     version: 4.4.5-ent
     type: ReplicaSet
     authentication:
       enabled: true
       modes: ["SHA"]
     cloudManager:
       configMapRef:
         name: my-project
     credentials: organization-secret
     persistent: true
     podSpec:
       podTemplate:
         spec:
          containers:
           - name: mongodb-enterprise-database
             resources:
               limits:
                 cpu: 2
                 memory: 1.5G
               requests:
                 cpu: 1
                 memory: 1G
               persistence:
                 single:
                   storage: 10Gi
   

2. Run the following command:

   copy

   kubectl apply -f <replica-set-conf>.yaml
   

Create a secret with your database user password¶

You can choose to use a cleartext password or a Base64-encoded password. Plaintext passwords use stringData.password and Base64-encoded passwords use data.password.

For a cleartext password, create and save the following YAML file:

apiVersion: v1
kind: Secret
metadata:
  name: mms-user-1-password
  # corresponds to user.spec.passwordSecretKeyRef.name
type: Opaque
stringData:
  password: <my-plain-text-password>
  # corresponds to user.spec.passwordSecretKeyRef.key

For a Base64-encoded password, create and save the following YAML file:

apiVersion: v1
kind: Secret
metadata:
  name: mms-user-1-password
  # corresponds to user.spec.passwordSecretKeyRef.name
type: Opaque
data:
  password: <base-64-encoded-password>
  # corresponds to user.spec.passwordSecretKeyRef.key

Create a database user.¶

1. Copy and save the following YAML file:

   copy

   apiVersion: mongodb.com/v1
   kind: MongoDBUser
   metadata:
     name: mms-scram-user-1
   spec:
     passwordSecretKeyRef:
       name: mms-user-1-password
       # Match to metadata.name of the User Secret
       key: password
     username: "mms-scram-user-1"
     db: "admin" #
     mongodbResourceRef:
       name: "demo-mongodb-cluster-1"
       # Match to MongoDB resource using authenticaiton
     roles:
     - db: "admin"
       name: "clusterAdmin"
     - db: "admin"
       name: "userAdminAnyDatabase"
     - db: "admin"
       name: "readWrite"
     - db: "admin"
       name: "userAdminAnyDatabase"
   

2. Run the following command:

   copy

   kubectl apply -f <database-user-conf>.yaml
   

Optional: View the newly created user in Cloud Manager or Ops Manager.¶

You can view the newly-created user in Cloud Manager or Ops Manager:

1. From the Project’s Deployment view, click the Security tab.
2. Click the MongoDB Users nested tab.

Connect to the replica set.¶

Perform the following steps in the Cloud Manager application:

1. Click Deployment in the left navigation.
2. Click ellipsis icon for the deployment to which you want to connect.
3. Click Connect to this instance.
4. Run the connection command in a terminal to connect to the deployment.
