2. Docker != Moby
• docker/docker -> moby/moby
• More than a simple rename
• Nothing changes for Docker releases (Docker CE/
EE)
• docker is for developers
• moby is for system architects

3. How Docker is being built

4. Moby
“Moby is a framework to assemble specialized container systems”
• A library of containerised component
• OS
• Container runtime
• Orchestration
• Infrastructure
• Storage, networking etc
• Tools to assemble to create runnable artifacts for different platform
• Bare Metal
• VM images
• Executables for Linux, Mac and Windows
• All of the components are containers
• Uses containerd as default container runtime

5. Moby Projects
• infrakit
• containerd
• runc
• notary
• linuxkit
• datakit
• vpnkit
• swarmkit

6. moby-tool
• The moby-tool builds systems
• by assembling different containerised
components
• LinuxKit is first use case
