CoreOS rkt / Container Linux (project ended) vs. Linux Containers LXD

CoreOS rkt is well suited for any development environment where operating systems and hardware are not homogeneous. CoreOS rkt allows us to write code on one machine with the confidence that it will work on any other. This has been immensely helpful as our developers are often switching to the latest and greatest machines and operating systems. CoreOS rkt is less suited for environments that are not Software as a Service. There is often no need to bring the entire developer environment and associated dependencies when delivering a one time product. In these environments CoreOS rkt just adds unneeded overhead.

Linux Containers LXD works very well when you, as a software developer using Linux, need to spin up a development environment to build and work on a specific piece of software. For example, you need to build some software that is tested and developed target Ubuntu 18.04. You're able to quickly create a container for Ubuntu 18.04 and log into it to run commands and build your software. This is easier to do than setting a virtual machine - e.g - via Virtual Box, but is a lot clunkier than doing it via Docker containers which give you a much more flexible configuration of the environment and are easier to start, stop, connect and share with other developers.

• Market share, it's often very difficult to find new talent who use CoreOS rkt.
• Lack of wow features, CoreOS rkt doesn't necessarily offer any immediate advantages over other container solutions.

Incentivized

• Ease of use.
• Copying containers from one machine to another.
• Creation of containers with config files similar to Docker.

Linux Containers LXD feels like a more primitive version of docker, docker-compose and similar projects from the docker ecosystem. The Dockerfile and docker-compose.yml methods of specifying a container setup, as well as the network and file configurations afforded by Docker make working with containers much easier and more reproducible than with Linux Containers LXD.

Incentivized

• Developers spend less time configuring and more time coding.
• Less time training developers as CoreOS rkt lets them use whatever hardware and operating system they want.
• Reduced our IT costs, solutions are containerized using CoreOS rkt meaning they can write one solution with many developers in mind.

Incentivized

• Save workload.
• Save time.
