@hendolim since you've got more experience working with UBI8, let me know if there's anything that might have a conflict with your work.

I removed a few packages that I added in order to get Ansible + the c libs to compile. With these changes, the image size is slighter larger than Debian 10 but it still seems comparable:

# docker images
REPOSITORY                                    TAG                 IMAGE ID            CREATED             SIZE
uf-redhat-8                                   latest              30c4c0c15580        4 minutes ago       468MB
base-redhat-8                                 latest              1a75d61c1c34        21 minutes ago      407MB
uf-debian-10                                  latest              92e876d73c91        4 days ago          458MB
base-debian-10                                latest              e6fe1d3e1415        4 days ago          397MB

I was able to start the redhat-8 image on the s390x box:

# docker run -d -P -e SPLUNK_START_ARGS=--accept-license -e SPLUNK_PASSWORD=helloworld uf-redhat-8:latest
# curl -k -u admin:helloworld https://localhost:32769/services/server/info
