How can I resize the EBS volumes to fit my project's needs?

When using CloudFormation or the Amazon CLI, please use the following JSON to specify volume sizes and encryption options on your new EC2 instance:

"ec2-instance": {
    "Type": "AWS::EC2::Instance",
    "Properties": {
      "ImageId": "ami-xxxxxxxxx",
      "InstanceType": "t2.small",
      "KeyName": "my-ec2-keypair",
      "BlockDeviceMappings": [
    { "DeviceName": "/dev/sda1",
  "Ebs": {
          "DeleteOnTermination":"true",
          "VolumeType":"gp2",
          "VolumeSize":"100"
  }
},
{ "DeviceName": "/dev/xvdl",
  "Ebs": {
          "DeleteOnTermination":"true",
          "VolumeType":"gp2",
          "VolumeSize":"10"
  }
},
{ "DeviceName": "/dev/xvdh",
  "Ebs": {
          "DeleteOnTermination":"true",
          "VolumeType":"gp2",
          "VolumeSize":"2"
  }
},
{ "DeviceName": "/dev/xvdx",
  "Ebs": {
            "DeleteOnTermination":"true",
            "VolumeType":"gp2",
            "VolumeSize":"2"
  }
},
  ]
}
}


If you are creating EC2 instances from the Amazon console, override the default volume sizes on Page 4 of the Launch Instance wizard.




(If you prefer an EC2 instance with a single root volume, please e-mail [email protected] and let us know. We're happy to accommodate!)
