Add Existing MongoDB Processes to Cloud Manager¶
On this page
Cloud Manager provides a wizard for adding your existing MongoDB deployments to monitoring and management. The wizard prompts you to install an Automation if none exists, and then prompts you to identify the cluster, the replica set, or the standalone to add. You can choose to add the deployment to Monitoring or to both Monitoring and Automation.
Considerations¶
Unique Names¶
Deployments must have unique names within the projects.
Important
Replica set, sharded cluster, and shard names within the same project must be unique. Failure to have unique names for the deployments will result in broken backup snapshots.
MongoDB Configuration Options¶
Automation doesn’t support all MongoDB options. To review which options are supported, see MongoDB Settings that Automation Supports.
TLS¶
If you enable TLS, the FQDN for the host serving a MongoDB process must match the SAN for the TLS certificate on that host.
Caution
Though you can use one TLS certificate with many SANs or a wildcard TLS certificate on each host, you should not. You should follow RFC 2818, section 3.1: keep the scope of TLS certificates as narrow as possible. This prevents man-in-the-middle attacks.
Preferred Hostnames¶
Set up a preferred hostname if you:
- Require a specific hostname, FQDN, IPv4 address or IPv6 address to access the MongoDB process, or
- Must specify the hostname to use for hosts with multiple aliases.
To learn more, see the Preferred Hostnames setting in Project Settings.
Managing Windows MongoDB Services¶
If you are adding an existing MongoDB process that runs as a Windows Service to Automation, Automation:
- Stops and disables the existing service
- Creates and starts a new service
Authentication¶
If the Cloud Manager project has MongoDB authentication settings enabled for its deployments, the MongoDB deployment you import must support the project’s authentication mechanism.
If your MongoDB deployment requires authentication, you must provide the necessary credentials for monitoring when adding the deployment to Cloud Manager.
If the deployment doesn’t use Automation, but did use Backup, Monitoring, or both, you can find those credentials where the credentials were before updating to the MongoDB Agent.
If the deployment doesn’t use Automation, but will use Backup, Monitoring, or both:
- Create the credentials to the MongoDB Deployment.
- Add the credentials you granted those functions to Cloud Manager after you add the MongoDB processes.
If the deployment uses Automation, Cloud Manager uses the credentials from the legacy Automation Agent. You can delete the credentials from the legacy Backup, and Monitoring Agents. The MongoDB Agent uses those credentials for its Automation, Backup, and Monitoring functions.
If the deployment will use Automation but did not prior to being imported, you need to add the
mms-automation
user to the database processes you imported and add the user’s credentials to Cloud Manager.To learn more, see Add Credentials for Automation.
Automation and Updated Security Settings Upon Import¶
Adding a MongoDB deployment to automation may affect the security settings of the Cloud Manager project or the MongoDB deployment or both.
Enables Cloud Manager Project Security Setting¶
If the MongoDB deployment requires authentication but the Cloud Manager project does not have authentication settings enabled, upon successful addition of the MongoDB deployment to automation, the project’s security settings will have the security settings of the newly imported deployment.
Note
The import process only enables the Cloud Manager project’s security setting if the project’s security setting is currently not enabled. If the project’s security setting is currently enabled, the import process does not disable the project’s security setting or change its enabled authentication mechanism.
Imports MongoDB Users and Roles¶
Note
The following applies for situations where at least either the MongoDB deployment requires authentication or the Cloud Manager project has authentication settings enabled.
If the MongoDB deployment contains users or user-defined roles, you can choose to import these users and roles for Cloud Manager to manage. The imported users and roles are Synced to all managed deployments in the Cloud Manager project.
If the Enforce Consistent Set
value for the Cloud Manager project is YES
,
users and roles not imported are deleted from the MongoDB deployment.
If the Enforce Consistent Set
value for the Cloud Manager project is No
,
non-imported users and roles are not managed by Cloud Manager project but remain
in the MongoDB deployment. To manage these users and roles, you must
connect directly to the MongoDB deployment.
If importing users and roles, before you confirm and deploy the changes, you can, from the Authentication & Users and Authentication & Roles screens, remove specific users and roles from being imported by unmanaging these users. For details on unmanaging MongoDB users, see Manage or Unmanage MongoDB Users.
If the imported MongoDB deployment already has mms-backup-agent
and
mms-monitoring-agent
users in its admin
database, the import
procedure overrides the roles of these users with the roles for
mms-backup-agent
and mms-monitoring-agent
users as set in the
Cloud Manager project.
Applies to All Deployments in Cloud Manager Project¶
The project’s updated security settings, including all users and roles managed as part of the Cloud Manager project, apply to all deployments in the project, including the imported MongoDB deployment.
Cloud Manager restarts all deployments in the project with the new setting, including the imported MongoDB deployment. All deployments in the project will use the Cloud Manager automation keyfile upon restart.
If the existing deployment or deployments in the project require a different security profile from the imported process, create a new project into which you can import the MongoDB deployment.
Examples of Imported Users¶
Note
The following applies for situations where at least either the MongoDB deployment requires authentication or the Cloud Manager project has authentication settings enabled.
If you choose to import the MongoDB users and custom roles, once Cloud Manager
project manages the MongoDB deployment, regardless of the value of Enforce
Consistent Set
:
Enforce Consistent Set |
Results |
---|---|
Yes or No |
|
If you choose not to import the users, once Cloud Manager project manages the MongoDB deployment:
Enforce Consistent Set |
Results |
---|---|
Yes |
|
No |
|
Prerequisites¶
If the Cloud Manager project does not have authentication settings enabled, but the MongoDB process requires authentication, add the MongoDB Agent user for the Cloud Manager project with the appropriate roles.
- The import process displays the required roles for the user.
- The added user becomes the project’s MongoDB Agent user.
If the Cloud Manager project has authentication settings enabled, add the Cloud Manager project’s MongoDB Agent user to the MongoDB process.
To find the MongoDB Agent user, click Deployments, then Security, then Users.
To find the password for the Cloud Manager project’s MongoDB Agent user, you can use the UI, the API or the configuration backup file:
- Using the UI
Navigate to Deployment, Security, and then Authentication & TLS/SSL
Click Edit Settings.
Click Next until you see the Configure Cloud Manager Agents page.
Click Show to the right of the MongoDB Agent Password field.
The MongoDB Agent’s password displays.
- Using the API
Use the Automation Configuration Resource endpoint:
- Using the Cloud Manager Configuration Backup file
Open the
mmsConfigBackup
file in your preferred text editor and find theautoPwd
value.
Example
If the Cloud Manager project has
Username/Password
mechanism selected for its authentication settings, add the
project’s Cloud Manager MongoDB Agents User mms-automation
to the
admin
database in the MongoDB deployment to import.
Important
If you are adding a sharded cluster, you must create this user through the mongos and on every shard. That is, create the user both as a cluster wide user through mongos as well as a shard local user on each shard.
Procedures¶
Add MongoDB Processes¶
To add existing MongoDB processes to Cloud Manager:
Click Add New and select Existing MongoDB Deployment.¶
Follow the prompts to add the deployment.¶
Add Authentication Credentials to your Deployment¶
After you add existing MongoDB process to Cloud Manager, you might have to add authentication credentials for the new deployments if authentication is enabled for the project into which you imported the deployment. See Authentication to learn in which situations you must add Automation, Monitoring, or Backup credentials for your new deployment.
Note
If you are adding a deployment that you intend to live migrate to Atlas, you need to add credentials for Monitoring only.
Select the authentication mechanism that you want to use:
- SCRAM-SHA
- LDAP
- Kerberos
- X.509
Add Credentials for Automation¶
To add credentials for a deployment that will use Automation but did not before you imported it to Cloud Manager:
