Creating a Docker Base Image for Faster Deployments

My Debian (x86_64) based - Dockerfile fragment :

imho: The key difference might be that I tried to install base Julia and the Julia packages in one step, to keep the final Docker image as small as possible.

FROM debian:bookworm-backports

# Since 1.9.0 Julia, the CPU target is set to "native" by default.
# This settings avoids the need to compile the Julia packages for the specific CPU architecture of the host machine
# Make sure the image can be used on any x86_64 machine by setting JULIA_CPU_TARGET
# to the same value used by the generic julia binaries, see
# https://github.com/JuliaCI/julia-buildkite/blob/4b6932992f7985af71fc3f73af77abf4d25bd146/utilities/build_envs.sh#L23-L31
