Adding glibc-langpack-en solved the problem. In the Dockerfile: RUN yum install -y glibc-langpack-en

I tried several other suggestions concerning adding different locale setting to commands such as: initdb -E UTF8 --locale=en_US.utf8 or RUN localedef -i en_US -f UTF-8 en_US.UTF-8 . Those did not work for me.
