#50 [Enhancement] Reduced Docker image size (250MB off compressed image a… Pull request opened by diadatp …nd 600MB off on disk size). • IUS repository addition was made CentOS 6/7 agnostic in anticipation of CentOS 6 EOL in Q4 2020. • CHECK: Python3 package install was preserved despite no use within the repository. • Package installation was merged into a single RUN command along with deletion of yum cache. • COPY replaced with ADD wherever applicable. Image build was successful and "make test" completed successfully as well. Image is available at diadatp/openlane:rc3 and has a compressed size of 290MB compared to efabless/openlane:rc3's 540MB. efabless/openlane Travis CI: Build Created
