Update the Automation Configuration

A project’s automation configuration determines the goal state of its MongoDB processes and agents. The MongoDB Agent builds the deployment according to the goals specified.

To update the configuration:

1. Retrieve the current configuration.
2. Make changes as needed, changing only those items you want modified.
3. Replace the entire configuration using PUT. You must use PUT. Do not use PATCH.

Note

Some parameters cannot be updated through the automationConfig endpoint. To learn more, see:

• Update Agent Versions
• Update Backup Log Settings
• Update Monitoring Log Settings

Prerequisites

You must have access to the API. To learn more, see Configure API Access.

Variables for Automation Config API Resources

The API resources use one or more of these variables. Replace these variables with your desired values before calling these API resources.

Name	Type	Description
PUBLIC-KEY	string	Your public API Key for your API credentials.
PRIVATE-KEY	string	Your private API Key for your API credentials.
cloud.mongodb.com	string	URL of your Cloud Manager instance.
GROUP-ID	string	Unique identifier of your project from your Project Settings.
CLUSTER-ID	string	Unique identifier of your cluster.

Procedure

1

Retrieve and validate the automation configuration from Cloud Manager.

1. Use the automationConfig resource to retrieve the configuration. Issue the following command, replacing the placeholders with the Variables for Automation Config API Resources.

   copy

   curl --user "{PUBLIC-KEY}:{PRIVATE-KEY}" --digest \
        --request GET "https://cloud.mongodb.com/api/public/v1.0/groups/{PROJECT-ID}/automationConfig?pretty=true" \
        --output currentAutomationConfig.json
   

2. Validate the downloaded Automation Configuration file.

   Compare the version field of the currentAutomationConfig.json with that of the Automation Configuration backup file, mms-cluster-config-backup.json. The version value is the last element in both JSON documents. You can find this file on any host running the MongoDB Agent at:

   • Linux and macOS: /var/lib/mongodb-mms-automation/mms-cluster-config-backup.json
   • Windows: %SystemDrive%\MMSAutomation\versions\mms-cluster-config-backup.json

   If the version values match, you are working with the current version of the Automation Configuration file.

2

Edit the downloaded automation configuration file.

Open currentAutomationConfig.json in your preferred text editor.

To learn more about the automation configuration options, see Automation Configuration.

If you’re updating the MongoDB Agent, see Update Agent Versions before continuing with this procedure.

3

Send the updated automation configuration.

Use the automationConfig resource to send the updated automation configuration.

Issue the following command, replacing {configuration-document} with path to the updated configuration document and the placeholders with the Variables for Automation Config API Resources.

copy

curl --user "{PUBLIC-KEY}:{PRIVATE-KEY}" --digest \
     --header "Content-Type: application/json"
     --request PUT "https://cloud.mongodb.com/api/public/v1.0/groups/{PROJECT-ID}/automationConfig?pretty=true" \
     --data '
         @{configuration_document}
       '

Upon successful update of the configuration, the API returns the HTTP 200 OK status code to indicate the request has succeeded.

4

Confirm successful update of the automation configuration.

Retrieve the automation configuration from Cloud Manager and confirm it contains the changes. To retrieve the configuration, issue the following command, replacing the placeholders with the Variables for Automation Config API Resources.

copy

curl --user "{PUBLIC-KEY}:{PRIVATE-KEY}" --digest \
     --request GET "https://cloud.mongodb.com/api/public/v1.0/groups/{PROJECT-ID}/automationConfig?pretty=true"

5

Check the deployment status to ensure goal state is reached.

Use the automationStatus resource to retrieve the deployment status. Issue the following command, replacing the placeholders with the Variables for Automation Config API Resources.

copy

curl --user "{PUBLIC-KEY}:{PRIVATE-KEY}" --digest \
     --request GET "https://cloud.mongodb.com/api/public/v1.0/groups/{PROJECT-ID}/automationStatus?pretty=true"

Confirm that the values of all the lastGoalVersionAchieved fields in the processes array match the goalVersion field. To learn about deployment status, see Get Automation Status of Latest Plan.
