On December 2nd, a surprise announcement made waves in the Kubernetes Twitter-sphere - that after the upcoming 1.20 release, Docker would be officially deprecated.

Oh no!

Due to widespread confusion over what “Docker” means in specific contexts, many people panicked - myself included. Due to its popularity and ease of use, the Docker engine has become synonymous with “containers”. However, Docker is really an entire ecosystem of container tools and processes, including building and shipping container images. So what does this announcement mean, and what are the implications for everyone using it?
