Oracle开始支持在docker上oracle数据库了，注意，是单实例，RAC不支持。docker的操作系统需要时候Oracle linux 7或者RHEL 7。
Oracle will support customers running Oracle Database (single instance) in Docker containers. Oracle will only provide support when running the database in Docker containers running on Oracle Linux and Red Hat RHEL. Supported versions of these Linux distributions are
Oracle Linux 7
Red Hat Enterprise Linux 7 (RHEL)Oracle does not support Oracle Database running in a Real Application Clusters (RAC) configuration in Docker containers.
另外，在github上也有一个非官方的如何制作oracle database on docker的image。
