This chapter is all about utilizing the deep integration that Kubernetes has with the AWS native storage solution Elastic Block Store (EBS). Amazon EBS provides network attached storage as a service, and is the primary solution used to provide block storage to EC2 instances.
Nearly every EC2 instance launched is backed by an EBS root volume (created from an AMI machine image). Because EBS storage is network attached, if an underlying machine hosting an EC2 instance fails in some way, the data stored on the volume is safe as it is automatically replicated across multiple physical storage devices.
In addition to being used to store the root filesystem of EC2 instances, additional EBS volumes can be attached to EC2 instances and mounted on demand via the AWS API. Kubernetes integration with AWS EBS makes use of this to provide persistent volumes that can be used by...
