Docker on ARM64¶
Docker on ARM64 functions much the same way as on x86, however, a Docker host can only run containers built for its architecture. Thankfully, multi-architecture support has been built into recent docker versions.
root@debian-arm64:~# uname -a Linux debian-arm64 4.19.76 #2 SMP PREEMPT Tue Oct 15 01:03:53 UTC 2019 aarch64 GNU/Linux root@debian-arm64:~# docker run -i -t debian:latest Unable to find image 'debian:latest' locally latest: Pulling from library/debian 627706d65d1d: Pull complete Digest: sha256:f19be6b8095d6ea46f5345e2651eec4e5ee9e84fc83f3bc3b73587197853dc9e Status: Downloaded newer image for debian:latest root@b9bf9b807bb6:/# uname -a Linux b9bf9b807bb6 4.19.76-dirty #2 SMP PREEMPT Tue Oct 15 01:03:53 UTC 2019 aarch64 GNU/Linux
It is also possible to run 32-bit ARM (
arm32v7) Docker images on the LS1088 - as the Cortex-A53 is backwards
docker run -i -t arm32v7/debian:latest root@340a4dca86e3:/# bash --version GNU bash, version 5.0.3(1)-release (arm-unknown-linux-gnueabihf) Copyright (C) 2019 Free Software Foundation, Inc.

.. however, be mindful that other ARM64 CPUs, especially those made by other vendors (Ampere, Marvell) do not have this backwards compatibility.
- Docker Official Images - Architectures other than amd64?
- Docker Hub - arm64v8 images
- linuxserver.io container library - many of these are multi-arch, containers for UniFi,nextcloud and other interesting applications
