The Road To Kubernetes: How Older Technologies Add Up

• docker

  Docker - the open-source application container engine (by microsoft)

  

The initial release of Docker was on March 20th 2013. Important to note is that containers are a more of a concept, and Docker is an implementation. What Docker brought to the table was a container image hosting service as well as software to orchestrate the more difficult parts of the container setup process. Docker also provided a very simplistic image definition: the Dockerfile. Compared to what needed to be done for virtual machine style builds Dockerfile builds simplified the process and used an incremental diff patching feature which enabled more modular organization of images. Images hosted on Docker's platform could be utilized in this process allowing for vendor solution tie-in. Having a business backing it also helped with corporate adoption of containers.

  OCI Distribution Specification

  

Kubernetes on the backend used to utilize docker for much of its container runtime solutions. One of the modular features of Kubernetes is the ability to utilize a Container Runtime Interface or CRI. The problem was that Docker didn't really meet the spec properly and they had to maintain a shim to translate properly. Instead users could utilize the popular containerd or cri-o runtimes. These follow the Open Container Initiative or OCI's guidelines on container formats.

  Production-Grade Container Scheduling and Management

  

Kubernetes was first released on September 9, 2014. This release timeline is part of what helped it gain a foothold over Docker Swarm. It was an open source version of an internal Google project. Features of container orchestration were presented in a more modular fashion along with scaling functionality. You can chose how your networking stack works, your load balancing, container runtime, and filesystem interfaces. Availability of an API allowed for more programmatic interactions with orchestration, making it tie in very well with CI/CD solutions. However, the big issue it has is complexity of setup. Putting together a Kubernetes cluster with basic functionality is certainly no easy feat.
