In my opinion its on its way out. CNCF and k8s has already basically replaced it with the CRI initiative and containerd[0][1]. Runc, rkt, and a multitude of other tools run containers. img, ocra-build, and others can build them.

[0] I realize this is from Docker as well but I feel it supports my point that Docker, Inc themselves are shedding baggage to still stay relevant.

I'll have to look into it thanks. I'd like to not end up requiring different tools to run the same container on Windows/Mac and Linux. Currently my workflow is easy, I create my Dockerfiles on a mac, do all of the building and testing, and then just tell devs on Windows to pull a repo and do a docker-compose --build up. I hope in the future this will not grow into tool hunting.

You'll probably be able to continue using the same tools across platforms to run containers.

I personally feel that Docker tries to do too much, almost the systemd of the container world. I believe having alternative container runtimes and build systems decoupled from Docker (both in the running program sense but also the company) will be the best in the long run.

With or without docker your workflow will remain the same. Its the image itself (the CRI spec) that makes that cross-platform magic work. I myself do my development on a Windows machine, ship a tar.gz off to Google's Cloud Builder to build the image and publish to a registry which then gets tested and debugged on a linux host.
