CoreOS rkt / Container Linux (project ended)

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.

Kubernetes

Kubernetes is ideally when container orchestration is required, allowing to scale an application up or down depending on the workload of the application/service.Portability of the Helm chart definition makes it possible to change the hosting platform easily without rewriting the whole application stack or depending on another configuration management tool (e.g. Ansible).

Pros

CoreOS rkt / Container Linux (project ended)

  • Running a secure container without messing up with low-level details
  • Very clear and straightforward approach to building a container
  • A way to go for new projects thinking of containers
  • Comprehensive and well-written documentation compatible with UNIX keep it simple way of thinking

Kubernetes

  • Makes sure that the workload remains UP & running by maintaining the desired state.
  • Gives a lot of flexibility in choosing the networking, storage, monitoring, etc solutions of your choice.
  • The biggest advantage is to upgrade the application with a new version without any downtime.
  • Portability of the code is possible up to a great extent.

Cons

CoreOS rkt / Container Linux (project ended)

  • 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.

Kubernetes

  • We had several problems with its NFS, which is responsible for syncing the code across the cluster
  • On several instances the pods go into UNKNOWN state in which case restarting the entire node is the only solution
  • As a user of the existing setup given to me, I wasn't able to allocate only some CPU cores on a single host. It was either all or zero making cluster utilization sub-optimal

Kubernetes

Most of the required features for any orchestration tool or framework, which is provided by Kubernetes. After understanding all modules and features of the K8S, it is the best fit for us as compared with others out there.

Return on Investment

CoreOS rkt / Container Linux (project ended)

  • 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.

Kubernetes

  • Because of microservices, Kubernetes makes it easy to find the cost of each application easily.
  • Like every new technology, initially, it took more resources to educate ourselves but over a period of time, I believe it's going to be worth it.
