Docker Ubuntu:20.04 not starting on arm64 host?

Question

ARM

Created a simple Dockerfile:

FROM ubuntu:20.04

CMD ["bash"]

I make a build on a Windoiws or Ubuntu host - everything builds and runs without problems
I do the same on a host with Arm64 (Oracle Cloud) - the build runs without problems, but crashes at startup

Who has experience with dockers on Arm64, what am I doing wrong?

Answer 1

You need: arm64v8/ubuntu:20.04, not ubuntu:20.04, which is for x86 (amd64)
