boot2docker vs KubeVirt: What are the differences?
Developers describe boot2docker as "Lightweight Linux for Docker". boot2docker is a lightweight Linux distribution based on Tiny Core Linux made specifically to run Docker containers. It runs completely from RAM, weighs ~27MB and boots in ~5s (YMMV). On the other hand, KubeVirt is detailed as "Virtual Machine Management on Kubernetes". It addresses the needs of development teams that have adopted or want to adopt Kubernetes but possess existing Virtual Machine-based workloads that cannot be easily containerized. More specifically, the technology provides a unified development platform where developers can build, modify, and deploy applications residing in both Application Containers as well as Virtual Machines in a common, shared environment.
boot2docker and KubeVirt can be categorized as "Virtual Machine Management" tools.
Some of the features offered by boot2docker are:
- Kernel 3.14.1 with AUFS, Docker 0.10.1, LXC 0.8.0
- Container persistence via disk automount on /var/lib/docker
- SSH keys persistence via disk automount
On the other hand, KubeVirt provides the following key features:
- Open Source
- Kubernetes Compatible
- Windows and Linux VMs
boot2docker and KubeVirt are both open source tools. boot2docker with 8.34K GitHub stars and 1.24K forks on GitHub appears to be more popular than KubeVirt with 1.86K GitHub stars and 422 GitHub forks.
