To be honest I'm not a Docker expert.
I did some stuff for what we needed some time back.
Maybe someone else @ oracle-l will know.

Ohk. I got your point, it explains. why i see them in the "docker history
<image> "
One last question if you dont mind :) .
In your opinion what would be the best way to get a 12.2.0.1 Apr 2020 RU
image build and it be less than 2GB or least possible and not like 16GB .
And i want to be able to do this in future for any RU so want to script it
as well.

You will need to build brand new image in one go.
Squash only works on interim images created by docker in build process.
If you build on top of existing image all that image is still there.
Images are immutable.

Jacek,
Do you have scripts for creating patched RU image on top of enterprise
edition minimal DBs as well? That is my end goal.
Even if i use the cleanup.sh on my already created RU image and do a
pre-build DB image .it doesnt remove the size from lower layers.

Next I will use your script to build the base image and see what happens
after applying the patch.

We went from 8.5GB to 2.5-3.5GB
Compressed (on dockerhub) they are way smaller.
Starrup time (including download from dockerhub) is also very good.

Thanks much for the reply Jacek! I will surely check your scripts :)
. Appreciate your inputs.
I have a question if you don't mind.
Can you please tell me how much space reduction at image level did
you achieve with these scripts. I am yet to test your scripts to see for
myself, waiting for a new machine to get allocated for my testing.
Also which file tells what all things you removed.
Cheers,
Kunwar

We're using slimmed images for utPLSQL.
From 11gR2 to 19c
They work fine for our needs though we've removed some things that
might be needed in some other cases.
See:
https://github.com/utPLSQL/docker-scripts
We use CDB-only to make DB even smaller.
If you look at how DB is composed you'll see all the things we
removed.
Hope this helps
Jacek

Hi Listers,
I am researching on squash option to reduce this apr 2020 RU size
to few GBs only .
[oracle@testserver testdocker]$ docker image ls

Can i reduce the size of this Apr2020 ru image to like 2gb with a
pre-built database or something if my plan is to run just few queries
in
the image for multiple users. So maybe the build of base image (
12.2.0.1-ee ) will have to be done .
I read squash option , but i am not sure if i can run squash on
the April 2020 image in order to do that.
