This is a case where creativity is not particularly rewarded if you want it to work and get meaningful help, my advice is to use the supported hardware architecture and operating system version. You might not even be able to tell when things aren't working as they should. Linux being what it is (flexible), lots of people have gotten the images to run on other flavors like Ubuntu with a bit of creativity, but only on x86 processors and even then the results are not guaranteed by Oracle: you won't be able to get support or practical advice when (and it's always when, not if in IT) things don't work as expected. The referenced My Oracle Support Doc ID goes on to say that the database binaries in their Docker image are built specifically for Oracle Linux hosts, and will also work on Red Hat. For more details please see My Oracle Support note: Oracle Support for Database Running on Docker (Doc ID 2216342.1) is supported for Oracle Linux 7 and Red Hat Enterprise Linux (RHEL) 7. Oracle Database Docker images are only supported with Oracle Linux 7 or Red Hat Enterprise Linux 7 as the host OS.Oracle Database is not supported on ARM processors, only Intel.
