<strong>Bottlerocket</strong>, is a Linux-based open source operating system and it is specially designed and developed to <strong>run various containers</strong> on virtual machines. Bottlerocket supports both types of container images: Docker and Open Container Initiative (OCI) format. That proves it is compatible with all Linux-based containers.

From a security perspective, Bottlerocket prevents the system access via SSH and performs file integrity checks during boot time. Bottlerocket uses essential software to run containers, which improves resource utilization.
