I had docker 1.7.1, I was following james turbnall the docker book . created two images (apache, jekyll) , created a jekyll container then I created apache container as well with the -P tag with EXPOSE 80 in the docker file but as i ran docker port 80 but no public port error.
then i upgraded to docker 1.8.1 but nothing changed I tried -P , -p , EXPOSE and every argument but i can't get it fixed .
My ports column when running Docker ps -a is always empty.
