Optimizing the Optimized Docker Image for Oracle XE 18c (18.4.0) including Archivelog
Posted by Dirk Nachbar on Friday, May 03, 2019
On 1st May 2019 I was publishing a solution on how to optimize the Docker image for Oracle XE 18c from 8.7 GB down to 5.41 GB (https://dirknachbar.blogspot.com/2019/05/optimized-docker-image-for-oracle-xe.html).
In the last 2 days I was playing a bit more with my optimized Docker image for Oracle XE 18c and I was able to downsize the Docker image once again to a current size of 4.02 GB. So its more than 50% of savings from the original Docker image size.
I mainly removed unnecessary directories from the $ORACLE_HOME and several binaries, which are not required in my opinion and I strip some of the big binaries to remove the comments from them.
You can find the optimized optimized Docker Image for Oracle XE 18c (18.4) in my GitHub Repository https://github.com/DirkNachbar/Docker/tree/master/OracleXE
Here is the list of directories and binaries which I removed from the image in order to come down to 4.02 GB:
I will continue to try to downsize the Docker image for Oracle XE 18c a bit more within the next days and will post updates on these topic.

I will continue to try to downsize the Docker image for Oracle XE 18c a bit more within the next days and will post updates on these topic.
