Recently I was in the need to create multiple directories at once in my Dockerfile. Using bash as a shell the shell expansion feature comes in handy:
For quite a while I am looking for a private Docker registry server which is easy to set up and fairly trivial to run in our IT infrastructure, e.g. being able to connect to our central LDAP server for user management. A few months back I realized that the next major version of Nexus will be able to host docker images. Since we already have a nexus instance running this seemed like a natural fit for us. Finally, I found some time to play with the current M7 release which already offers the docker registry feature.
