Configuring Amazon EC2 instances with namespace options - AWS Elastic Beanstalk

Configuring Amazon EC2 instances with namespace options

You can use the configuration options in the aws:autoscaling:launchconfiguration namespace to configure the instances for your environment, including additional options that aren't available in the console.

Important

The DisableIMDSv1, RootVolumeType, or BlockDeviceMappings option setting can cause Elastic Beanstalk to create an environment with a launch template or update an existing environment from launch configurations to launch templates. For more information, see Launch Templates.

The following configuration file example uses the basic configuration options that are in this topic. For example, it uses the DisableIMDSv1 option, which is discussed in IMDS. It also uses the EC2KeyName and IamInstanceProfile options that are discussed in Security, and the BlockDeviceMappings option, which isn't available in the console.

option_settings:
  aws:autoscaling:launchconfiguration:
    SecurityGroups: my-securitygroup
    MonitoringInterval: "1 minute"
    DisableIMDSv1: false
    EC2KeyName: my-keypair
    IamInstanceProfile: "aws-elasticbeanstalk-ec2-role"
    BlockDeviceMappings: "/dev/sdj=:100,/dev/sdh=snap-51eef269,/dev/sdb=ephemeral0"

You can use BlockDeviceMappings to configure additional block devices for your instances. For more information, see Block Device Mapping in the Amazon EC2 User Guide.

The EB CLI and Elastic Beanstalk console apply recommended values for the preceding options. You must remove these settings if you want to use configuration files to configure the same. See Recommended values for details.
