Helm Charts Quick Start

Register for an Atlas account or log in.

Register a new Atlas Account or Login to Your Atlas Account.

Create API keys for your organization.

Create an API Key in an Organization and configure the API Access List.

You need the following public API key, private API key, and the organization ID information to configure Atlas Kubernetes Operator access to Atlas.

• If you want Atlas Kubernetes Operator to create a new Atlas project, Create an API Key in an Organization and configure the API Access List.

  Important

  You must assign the API key the Organization Project Creator organization role or higher.

• If you want to work with an existing Atlas project, Create an API Key for a Project and configure the API Access List.

  Important

  You must assign the API key the Project Owner project role.

Deploy Atlas Kubernetes Operator.

Run one of the following sets of commands:

• If you want Atlas Kubernetes Operator to watch all namespaces in the Kubernetes cluster, run the following commands:

  helm repo add mongodb https://mongodb.github.io/helm-charts
  helm install atlas-operator --namespace=atlas-operator --create-namespace mongodb/mongodb-atlas-operator

• If you want Atlas Kubernetes Operator to watch only its own namespace, set the --watchNamespaces flag to its own namespace, and run the following command:

  Note

  You can set the --watchNamespaces flag only to its own namespace. Setting the --watchNamespaces flag to any other namespace is currently unsupported.

  helm install atlas-operator --namespace=atlas-operator --set watchNamespaces=atlas-operator --create-namespace mongodb/mongodb-atlas-operator

Deploy the Atlas cluster.

The --set flags in the following example override the Values.yaml file values with your Atlas project name, organization ID, and API keys.

Run the following command:

helm install atlas-cluster \
mongodb/atlas-cluster \
--namespace=my-cluster \
--create-namespace \
--set project.atlasProjectName='My Project' \
--set atlas.orgId='<orgid>' \
--set atlas.publicApiKey='<publicKey>' \
--set atlas.privateApiKey='<privateApiKey>'

Alternatively, you can clone the helm-charts project on GitHub, edit the Values.yaml file directly, and add your local directory with the following command:

helm repo add mongodb <your-updated-helm-charts-directory>

To learn more about the available parameters, see AtlasCluster Custom Resource.

Check the status of your database user.

Run the following command until you recieve a True response, which indicates the database user is ready:

kubectl get atlasdatabaseusers atlas-cluster-admin-user -o=jsonpath='{.status.conditions[?(@.type=="Ready")].status}'

Retrieve the secret that Atlas Kubernetes Operator created to connect to the cluster.

Run the following command:

kubectl get secret my-project-atlas-atlas-cluster-admin-user -o json | jq -r '.data | with_entries(.value |= @base64d)';

{
   "connectionStringStandard": "mongodb://admin-user:%25SomeLong%25password$foradmin@atlas-cluster-shard-00-00.nlrvs.mongodb.net:27017,atlas-cluster-shard-00-01.nlrvs.mongodb.net:27017,atlas-cluster-shard-00-02.nlrvs.mongodb.net:27017/?ssl=true&authSource=admin&replicaSet=atlas-11q9bn-shard-0",
   "connectionStringStandardSrv": "mongodb+srv://admin-user:%25SomeLong%25password$foradmin@atlas-cluster.nlrvs.mongodb.net",
   "password": "%SomeLong%password$foradmin",
   "username": "admin-user"
}

You can use this secret in your application:

containers:
 - name: test-app
   env:
     - name: "CONNECTION_STRING"
       valueFrom:
         secretKeyRef:
           name: my-project-atlas-atlas-cluster-admin-user
           key: connectionStringStandardSrv
