help Bottlerocket FAQ

What is AWS Bottlerocket used for?

AWS Bottlerocket is an open-source Linux operating system specifically engineered to run containers. It is heavily optimized for Kubernetes and Amazon EKS workloads.

Can I SSH into a Bottlerocket container host?

You cannot use traditional SSH with a password to access Bottlerocket, as it is designed for immutable infrastructure. Instead, administrators use out-of-band management tools or an admin container via SSM Session Manager.

How does Bottlerocket handle operating system updates?

Bottlerocket uses an image-based update mechanism for atomic transitions between software versions. This ensures that updates are either fully applied or safely rolled back during a reboot.

Does Bottlerocket support Docker natively?

Bottlerocket uses containerd by default as its container runtime, rather than installing the Docker daemon directly. This provides a more minimal attack surface for running orchestration workloads.
