Linux 3.8 introduced unprivileged user namespaces [pdf]
Will this make it easier to run docker without root / sudo?<p>That could fix the barrier of entry and make docker tutorials passed around more canonical. I would love it if docker "just worked" across machines when testing locally, commands and all.<p>Even sharing docker in open source projects, there's a learning curve for me where commands in the README won't work. Is it my docker installation? Version differences with docker? Docker compose? Did the container images I'm pulling in change some way?<p>Do I need sudo or not? I guess with proper group permissions I'm okay - but will the developer(s) I share instructions with have these permissions ready to go?<p>On StackOverflow: copy/pasting docker CLI (even given proper context fitting into a larger whole) commands and configs probably has a 50% success rate for commands, and maybe 10% if it's a config of some sort (e.g. compose files)
