Hi, If Docker image specified a USER in Dockerfile, docker will use this user when executing command in container. In Docker commands, it can be overriden with -u XX .
I do not find however in mesos.proto a way to do so. There is the "arguments" of DockerInfo that I could use to append this to the executor command line, but I think it is not advised as it may not be supported in future. Did I miss something ? Thanks Olvier
