Early this year, I wrote a blog to let you know that Oracle Database RAC was available on Docker. However, in that blog, I described several manual steps required to rebuild the image before you could start using the RAC database.
I’m now delighted to announce that you can simply download an Oracle Database RAC Docker image (under database) from the container registry. Furthermore, the image has a pre-installed / pre-built image—making it easier to have a RAC database for your demos, development or test environments.
Update to this post: Starting December 2021, Oracle Database 21c (21.3) comes with full production support for Oracle RAC on Docker! You can get more details on exactly what RAC images are supported for production databases on the Oracle MAA blog.
I began my love affair with Docker a year ago when @GeraldVenzl got me started with my very first 12.2 Multitenant container database on Docker and I have to say I absolutely love the convenience of having an Oracle Database directly on my MAC for demos and building test cases to help answer AskTOM questions.
Then about six months ago I got an opportunity to beta test RAC on Docker when I needed a two-node RAC cluster for a blog post on controlling where data is populated into In-Memory on a RAC cluster.
Now you have an opportunity to try RAC on Docker for yourself, as Oracle has just released Docker build files to create an Oracle RAC Database Docker image on Github.
