Hi,

Did you get any warning when pulling the image (or when running it) related to the arch not matching the detected host platform?

To make sure the right arch image is being used, could you pull bitnami/minideb:buster-arm64 instead? Could you send us the output of executing in your host:

uname -a

[lxm]

no warnings when pulling the image

outputs of uname -a on host

Linux xxxx-g4im6 4.19.36-vhulk1907.1.0.h702.eulerosv2r8.aarch64 #1 SMP Mon Mar 16 00:02:15 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux

bitnami/minideb:buster-arm64 works well
bitnami/minideb:buster will got error

container start initialization failed: standard_init_linux.go:219: exec user process caused "exec format error"

Hi
The error you got for bitnami/minideb:buster is normal as that image is for amd64 architectures.
Could you run docker images to the get images IDs ? When pulling bitnami/minideb:buster you should be getting the arm one as it is multiarch.

Hi,
I tried on a raspberry pi 4 with raspbian 64 bit and it worked for me:

It seems the issue could be related to the Docker client and the multiple arch variants moby/moby#34875 Could you try updating the docker client version? if not, as you mentioned, you can pull the one with 'arm' in the tag itself.
