Hello all, I just wanted to share this that if you using Docker version >= 1.6 and running your own private docker registry 2.0 and trying to deploy containers using mesos and marathon, there might be some issues with docker registry authentication because from docker version >=1.6, there is no .dockercfg file anymore, instead there is a .docker/config.json containing the credentials. So docker pull will fails on mesos-slaves.
In order to solve this, you can create a tar.gz file containing the directory structure as: # tar -tvf docker.tar.gz drwxr-xr-x root/root 0 2015-07-10 09:56 .docker/ -rw------- root/root 136 2015-07-09 13:46 .docker/config.json And add this tar file to uris. So basically when the mesos-slaves will pull inside the containers and extract it, it will provide the correct directory structure as per docker authentication requirements. I spent around 1 hour debugging it, so thought that it might be useful for others as well :) -- Pradeep Chhetri
