AWS Elastic Beanstalk - Increase Instance Disk Capacity

Question

I'm trying to use ElasticBeanstalk for an app with some big initial space requirements. It exceeds the default 8GB capacity of the EBS disk on the EC2 instances.

I tried to increase the disk capacity by using a bigger EC2 instance type. For instance, I used an m3.large, which AWS tells me should provide me with 1x32GB of storage.

However, when the Beanstalk environment launches, it still only shows 8GB. I tried to run the "resize2fs" command on the instance, but it didn't expand the volume to anything over 8GB.

Does anyone know how to get bigger instance storage on ElasticBeanstalk environments?

Answer 1

Example of solution for Elastic Beanstalk with ebextensions config:

application-root-dir/.ebextensions/001-filesystem.config:

option_settings:
  aws:autoscaling:launchconfiguration:
    RootVolumeType: gp2
    RootVolumeSize: "64"

Answer 2

There is a better way to do this now using RootVolumeType and RootVolumeSize in aws:autoscaling:launchconfiguration. Details are [here].1

Following is the relevant section from my cloudformation script to create elastic beanstalk

  {
    "Namespace": "aws:autoscaling:launchconfiguration",
    "OptionName": "RootVolumeType",
    "Value": "gp2"
  },
  {
    "Namespace": "aws:autoscaling:launchconfiguration",
    "OptionName": "RootVolumeSize",
    "Value": 25
  },

This can be easily achieved through ebextensions also.
