We evaluated CoreOS rkt and Docker when selecting software solutions for my department. We ended up using CoreOS rkt because of how well it fits with CoreOS and the choice of gRPC for the API. We provide a managed service that runs CoreOS on a bare metal server, CoreOS rkt was …

I have heard about others, but all my professional life I have been using Docker as my primary container and the thing is you just don't need anything else right now. Because Kubernetes supports Docker and Docker is open-source and just very simple to get started with. 10 …
Chose Mirantis Kubernetes Engine
I would also compare to BSD Jails, LXC, and Solaris Zones, but they weren't listed. One of the first reasons we decided to use Docker over other container applications is because Docker is the default everyone recommends and is easily the most popular. We found Docker to be …

RKT is Docker's main competitor and it is too immature to be used in production.

Open Source
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.

[Mirantis Cloud Native Suite (Docker Enterprise)] is the most advanced tool till now, which works as a VMs
and separates any single application from the dependencies. Also, this tool is
helping me in the agile development of the processes. It is strongly recommended to
almost all major organizations.

  • Containers - Docker is the go-to when using Containers, which are super useful if you need an environment that works both for Windows and Linux
  • Efficiency - Docker is very lightweight and doesn't demand too much from your CPU or server
  • CI/CD - Docker is excellent for plumbing into your build pipeline. It integrates nicely, is reliable, and has an easy set up.

Cons
Open Source
  • 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.

  • Containers are often opaque - if a container doesn't work out of the box, it's messy to fix.
  • Logging is complexified by the multiple containers and logs are often not piped to places you expect them to be.
  • Networking is complexified due to internal port mapping between containers, etc.

Docker's CLI has a lot of options, and they aren't all intuitive. And there are so many tools in the space (Docker Compose, Docker Swarm, etc) that have their own configuration as well. So while there is a lot to learn, most concepts transfer easily and can be learned once and applied across everything.

The community support for Docker is fantastic. There is almost always an answer for any issue I might encounter day-to-day, either on Stack Overflow, a helpful blog post, or the community Slack workspace. I've never come across a problem that I was unable to solve via some searching around in the community.

We've used XAMPP, PHPmyAdmin and similar local environments (our app is on PHP). Because of how easy you can change the configuration of libraries on PHP and versions (which is SO painful on XAMPP or other friendly LAMP local servers) we are using Docker right now. Also, being sure that the environment is exactly the same makes things easier for developing.

Return on Investment
Open Source
  • 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.

  • Docker has made it possible for us to deploy code faster, increasing the productivity of our development teams.
  • Docker has made it possible for us to decentralize our build and release system. This means that teams can deploy on their own schedule and our dev ops team can concentrate on building better tools rather than deploying for the teams
  • Docker has allowed us to virtualize our entire development process and made it much simpler to build out new data centers. This, in turn, is significantly increasing our ROI by providing a path forward for internationalization.
