we are trying with RHEL image  registry.access.redhat.com/ubi8/ubi-minimal 
in this image yum does not work we have to use microdnf / rpm. so we used 
below lines to 

RUN microdnf install 
https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
RUN microdnf install epel-release
RUN wget http://www.leptonica.com/source/leptonica-1.76.0.tar.gz
RUN wget 
https://sourceforge.net/projects/tesseract-ocr-alt/files/tesseract-ocr-3.02.02.tar.gz
RUN wget 
https://download.opensuse.org/repositories/home:/Alexander_Pozdnyakov/CentOS_8/
RUN wget  
https://build.opensuse.org/projects/home:Alexander_Pozdnyakov/public_key
RUN microdnf install tesseract

The above lines not working it throws error.

any help would be appreciated 

With regards
Yeshwanth
