I am having this same problem on my Raspberry Pi 3 with armv7 Alpine Linux 3.9.2. Docker version is 18.09.3-ce. I also have tried the steps on this page https://wiki.alpinelinux.org/wiki/Docker section " “WARNING: No {swap,memory} limit support.”
I run this command and get the same error:
$ docker run -it --rm arm32v7/alpine:3.9.2 /bin/ash
