Docker isn’t what I thought it was.
I thought it provided a way to run docker images on any host that supported docker. As it turns out, that’s not true.
I first encountered something fishy when I found this docker image on Docker Hub, whose description said, “FreeBSD Docker host is required to run this image.” I thought, “How is that even possible?” And sure enough, I could run the image just fine with a FreeBSD host. But when I tried to run it on my iMac, it silently failed. How could this be?
