Beanstalk: Roll Configuration Updates
This tutorial covers configuration updates that require a rolling update. This includes the following changes to infrastructure resources:
| Namespace: aws:autoscaling:launchconfiguration | Namespace: aws:ec2:vpc |
|---|---|
| EC2KeyName | VPCId |
| IamInstanceProfile | Subnets |
| ImageId | ELBSubnets |
| MonitoringInterval | ELBScheme |
| SecurityGroups | DBSubnets |
| SSHSourceRestriction | AssociatePublicIpAddress |
| BlockDeviceMappings | |
| RootVolumeType | |
| RootVolumeSize | |
| RootVolumeIOPS |
Once Maintenance is completed and the necessary Elastic Beanstalk configuration changes are made, a blue-green deployment is forced where a graceful replacement of existing instances with new, updated instances (that contain the new configuration change) takes place.
The tutorial covers In-ASG and Independent Beanstalk integration methods in separate steps.
Prerequisites
- A healthy Beanstalk environment in your AWS account
- Elastigroup is synced with Beanstalk environment.
- The most up-to-date Spot IAM policy is configured in your AWS account
In-ASG Beanstalk Integration Method
While in Maintenance Mode, the service remains available and your instances are still running.
-
Open the Elastigroup Management View. Under Configuration Update click Start Maintenance.
-
Perform the changes to the Beanstalk environment in the AWS Console.
-
After making the changes, select Roll Updates to initiate a blue/green deployment that gracefully replaces the Elastigroup's instances with new instances containing the configuration changes. To learn more about deployments and rolling in Elastigroup, click here.
Independent Integration Method
-
Perform the changes to the Beanstalk environment in the AWS Console.
-
In the Elastigroup Management View, under Actions select Beanstalk.
-
In the pop-up window, click Re-Import Config to import the updated configuration.
-
Configure the blue/green deployment to be initiated. The blue/green deployment gracefully replaces all the instances in the Elastigroup with new instances containing the configuration changes. For more on deployments and rolls in Elastigroup click here.

Click Save & Deploy.
