Bottlerocket, an OS for Containers, Previewed by Amazon Cloud

Amazon Web Services (AWS) announced a public preview of Bottlerocket, a bare-bones Linux platform tailored for hosting containers.AWS said it's being "purpose-built" for containers, unlike general-purpose OSes like the Amazon Linux server platform that require updates to be applied one package at a time. Bottlerocket incorporates a "single-step update mechanism" to greatly simplify the update process, AWS said. Instead of a package update system, Bottlerocket uses a simple, image-based model that allows for a rapid & complete rollback if necessary," wrote AWS evangelist Jeff Barr in a blog post announcing the public preview. "This removes opportunities for conflicts and breakage, and makes it easier for you to apply fleet-wide updates with confidence using orchestrators such as EKS [Amazon Elastic Container Service for Kubernetes].
