> * Images are just files. You can copy them around (or archive them) like any other file
Never heard of Singularity before, and it does look interesting. Wanted to point out though that you can create tarballs of Docker images, copy them around, and load them into a Docker instance. This is really common for air-gapped deployments.
I've never seen this mentioned in the official Docker docs. Is it a well-supported workflow?
Docker save and docker load- I use this often for air-gapped installations and it works exactly as well as docker pull in my experience.
Yes. https://docs.docker.com/engine/reference/commandline/save/
