Some of your points seems valid (although the writing style is hostile), but calling it "unnecessary" is over assumption. You think Docker is only used in deployment, but you are wrong. I use it do grade programming assignments, I distribute Dockerfiles to students, and it is very useful. I believe it is very useful in other aspects as well, just because you are unhappy does not make it unnecessary. I ran almost 30.000 containers on a single machine and it saved me many hours. I also had a incident with Docker in 0.6, when creating a new container it used to traverse all the containers metadata and when the container count reaches thousands it froze my server and I had to manually reboot it on 3AM, but hey that's okay, it can be fixed, I reported it on Github and it does not happen anymore. It is still useful to me, and still necessary.

Thank you for the feedback, that's actually quite an interesting use case of the Docker ecosystem. I've already updated the article to reflect this, as you raise the same point that many others made.

You should consider doing your students a favor and not tie them into a single for-profit company's technology (most will go on to use whatever you have taught them since they will have come to be comfortable with it during their studies). Consider using one of the App Container Specification's implementations -- there are already 3 prominent ones, all adhere to the standard which means their images are interchangeable and compatible with each other. The standard is community-driven, and stable at this time. It could even become a project to implement your own implementation for your school, teaching your students not only a ton about Linux, but the principals of containerization in the process.
