slim will build a micro-vm from a Dockerfile. Slim works by building and extracting a rootfs from a Dockerfile, and then merging that filesystem with a small minimal kernel that runs in RAM.
This results in a real VM that can boot instantly, while using very limited resources. If done properly, slim can allow you to design and build immutable unikernels for running services, or build tiny and embedded development environments.
Create a micro-vm from a Dockerfile. Use
build command with a directory containing a Dockerfile.
$ slim build images/alpine3.8-simple
The resulting image is only 23MB! It can be used in virtual box, kvm, or hyper-kit.
Provision a new instance of the given micro-vm image as a virtual machine.
$ slim run micro1 alpine3.8-simple
This short demo illustrates an image being built, booting with hyper kit in 3 seconds, and then accessing the vm from ssh.
