Atlas Kubernetes Operator

Custom Resources

`AtlasPrivateEndpoint` Custom Resource

Important

Legacy subresources are deprecated as of the release of their corresponding CRDs. If your configuration currently relies on the subresource form of this resource definition, migrate to a CRD.

The AtlasPrivateEndpoint custom resource configures a private endpoint for a Atlas project. This allows you to connect your cloud provider to Atlas without sending information through a public network. Private endpoints are unidirectional connections to Atlas from your virtual network.

Important

Custom Resources No Longer Delete Objects by Default

Atlas Kubernetes Operator uses custom resource configuration files to manage your Atlas configuration, but as of Atlas Kubernetes Operator 2.0, custom resources you delete in Kubernetes are no longer (by default) deleted in Atlas. Instead, Atlas Kubernetes Operator simply stops managing those resources in Atlas. For example, if you delete an AtlasProject Custom Resource in Kubernetes, by default the Atlas Kubernetes Operator no longer automatically deletes the corresponding project from Atlas. This change in behavior is intended to help prevent accidental or unexpected deletions. To learn more, including how to revert this behavior to the default used prior to Atlas Kubernetes Operator 2.0, see New Default: Deletion Protection in Atlas Kubernetes Operator 2.0.
Similarly, Atlas Kubernetes Operator does not delete teams from Atlas if you remove them from an Atlas project in Kubernetes with the Atlas Kubernetes Operator.

Explicitly define your desired configuration details in order to avoid implicitly using default Atlas configuration values. In some cases, inheriting Atlas defaults may result in a reconciliation loop which can prevent your custom resource from achieving a READY state. For example, explicitly defining your desired autoscaling behavior in your AtlasDeployment custom resource, as shown in the included example, ensures that a static instance size in your custom resource is not being repeatedly applied to an Atlas deployment which has autoscaling enabled.

autoScaling:
  diskGB:
    enabled: true
  compute:
    enabled: true
    scaleDownEnabled: true
    minInstanceSize: M30
    maxInstanceSize: M40

Atlas Kubernetes Operator takes one of the following actions using the Atlas Private Endpoint Service API Resource:

Creates a new private endpoint service.
Updates an existing private endpoint service.

To learn more about implementing private endpoints in Atlas Kubernetes Operator, see Manage Private Endpoints.

Examples

Basic Example

The following example shows an AtlasPrivateEndpoint custom resoure that defines an AWS private endpoint within the my-project project.

apiVersion: atlas.mongodb.com/v1
kind: AtlasPrivateEndpoint
metadata:
 name: my-atlas-pe1
spec:
  projectRef:
    name: my-project
    namespace: my-operator-namespace
  provider: AWS
  region: US_EAST_1
  awsConfiguration:
    - id: vpcpe-xyz

Independent CRD Example

The following example shows an AtlasPrivateEndpoint independent CRD that defines the same private endpoint defined in the Basic Example. This custom resource definition allows you to create this private endpoint in a project you don't manage in the same instance of Atlas Kubernetes Operator with which you define this resource. To enable independent operation, you must use an externalProjectRef instead of a projectRef, and you must supply a connectionSecret directly since this resource can't inherit API credentials from its parent project.

apiVersion: atlas.mongodb.com/v1
kind: AtlasPrivateEndpoint
metadata:
 name: my-atlas-pe1
spec:
  externalProjectRef:
    projectID: 66e2f2b621571b7e69a89b66
  connectionSecret:
    name: atlas-connection-secret
  provider: AWS
  region: US_EAST_1
  awsConfiguration:
    - id: vpcpe-xyz

Parameters

This section describes the AtlasPrivateEndpoint custom resource parameters available.

metadata.name

Type: string

Required

Name that the AtlasPrivateEndpoint Custom Resource uses to add this private endpoint to a project.

metadata.namespace

Type: string

Optional

Namespace that you want to contain the AtlasPrivateEndpoint custom resource. If unspecified, Atlas Kubernetes Operator uses the current namespace set by kubectl.

If you define a custom namespace, you must add it to the AtlasProject Custom Resource in the spec.privateEndpoint.privateEndpointRef.namespace field.

spec.awsConfiguration.id

Type: string

Conditional

ID of the private endpoint network interface. This parameter is mandatory for and limited to AWS private endpoints.

spec.azureConfiguration.id

Type: string

Conditional

ID of the private endpoint network interface. This parameter is mandatory for and limited to Azure private endpoints.

spec.azureConfiguration.ipAddress

Type: string

Conditional

IP address of the private endpoint in your Azure VNet. This parameter is mandatory for and limited to Azure private endpoints.

spec.connectionSecret.name

Type: string

Conditional

Name of the opaque secret that contains the organization ID and API keys that Atlas Kubernetes Operator uses to connect to Atlas. If unspecified, Atlas Kubernetes Operator falls back to either:

The spec.connectionSecretRef.name parameter of the parent atlasProject
The default global secret, if spec.connectionSecretRef.name is undefined for the parent atlasProject

This parameter is mandatory for independent CRDs.

Atlas Kubernetes Operator watches secrets only with the label atlas.mongodb.com/type=credentials to avoid watching unnecessary secrets.

The following example labels a secret:

kubectl label secret the-user-password atlas.mongodb.com/type=credentials

spec.externalProjectRef.id

Type: string

Conditional

ID of the project to which the private endpoint belongs. You must specify the project ID of an existing Atlas Project. This parameter is required for private endpoints that belong to projects managed by either:

A different instance of Atlas Kubernetes Operator
Tooling other than Atlas Kubernetes Operator

For deployments who belong to projects managed by the same instance of Atlas Kubernetes Operator, use spec.projectRef.name if you do not use spec.externalProjectRef.id.

A private endpoint can only belong to one project. To define the same private endpoint for multiple projects, create custom resource definitions for each project.

spec.gcpConfiguration.endpoints

Type: array

Conditional

List of individual private endpoints that comprise this endpoint group. This parameter is mandatory for and limited to Google Cloud private endpoints.

spec.gcpConfiguration.endpoints.[n].ipAddress

Type: string

Conditional

IP address to which the given Google Cloud private endpoint resolves. This parameter is mandatory for and limited to Google Cloud private endpoints.

spec.gcpConfiguration.endpoints.[n].name

Type: string

Conditional

Name uniquely identifying the given Google Cloud private endpoint. This parameter is mandatory for and limited to Google Cloud private endpoints.

spec.gcpConfiguration.groupName

Type: string

Conditional

Name that uniquely identifies a set of Google Cloud private endpoints. This parameter is mandatory for and limited to Google Cloud private endpoints.

spec.gcpConfiguration.projectId

Type: string

Conditional

Unique identifier for the Google Cloud project to which your private endpoints belong.

spec.projectRef.name

Type: string

Conditional

Name of the project to which the private endpoint belongs. You must specify an existing AtlasProject Custom Resource. This parameter applies only to private endpoints that belong to projects managed by the same instance Atlas Kubernetes Operator.

For private endpoints that belong to projects managed by either:

a different instance of Atlas Kubernetes Operator
tooling other than Atlas Kubernetes Operator

use spec.externalProjectRef.id.

A private endpoint can only belong to one project. To define the same private endpoint for multiple projects, create custom resource definitions for each project.

spec.projectRef.namespace

Type: string

Conditional

Namespace in which the AtlasProject Custom Resource specified in spec.projectRef.name exists.

For deployments that belong to projects managed by either:

a different instance of Atlas Kubernetes Operator
tooling other than Atlas Kubernetes Operator

do not set this parameter.

spec.provider

Type: string

Required

Name of the cloud service provider for which to create a private endpoint service.

spec.region

Type: string

Required

Cloud provider region in which to create a private endpoint service.
