[Edit] enabled gpgcheck

Solution to the image with error is to add before the wget CMD RUN yum -y install wget If you write it like this, it is the same result, just different execution: RUN wget http://www.us.apache.org/dist/tomcat/tomcat-6/v6.0.44/bin/apache-tomcat-6.0.44.tar.gz Don’t use the quotes and comma in RUN command.

So you could wrap your commands to redirect stderr to /dev/null (if there wasn’t anything else you cared about … Read more
