I quickly fixed/tried it.
First this package list pulls many unuseful system packages.
I added '--no-recommends' to reduce a bit:

RUN zypper ref && \
    zypper up -y && \
    zypper install -y --no-recommends $PACKAGES

This still install a bunch of unnecessary stuffs:

Creating group systemd-journal with gid 485.
Creating group systemd-network with gid 484.
Creating user systemd-network (systemd Network Management) with uid
484 and gid 484.
Creating group systemd-coredump with gid 483.
Creating user systemd-coredump (systemd Core Dumper) with uid 483 and gid 483.
Creating group systemd-timesync with gid 482.
Creating user systemd-timesync (systemd Time Synchronization) with uid
482 and gid 482.
Failed to connect to bus: No such file or directory

Then the resulting image takes the same than without --no-recommends:
1.1GB. No idea why.
At some point some package tried to talk to the network manager via
DBus to start sshd...

Second, while this works on x86_64, it fails on aarch64:

Problem: libcurl-devel-7.59.0-lp150.1.2.aarch64 requires libcurl4 =
7.59.0, but this requirement cannot be provided
  not installable providers: libcurl4-7.59.0-lp150.1.2.aarch64[repo-oss]
 Solution 1: downgrade of libcurl4-7.60.0-lp150.2.15.1.aarch64 to
libcurl4-7.59.0-lp150.1.2.aarch64
 Solution 2: do not install libcurl-devel-7.59.0-lp150.1.2.aarch64
 Solution 3: break libcurl-devel-7.59.0-lp150.1.2.aarch64 by ignoring
some of its dependencies

Not your fault. So I suppose you are planning to use this image to
compile QEMU for openSUSE/x86_64 only, is this correct?

Phil.
