问题 I'm following the docker-compose tutorial, to try and figure out how to get a django app to deploy: http://docs.docker.com/compose/django/ And everything's going smoothly (the app even works!) but the django project folder composeexample isn't created in my local project directory.

问题 Docker images are stored in $HOME/Library/Containers/com.docker.docker/Data but how to move those large files to an external drive for example? I have tried symbolic link, it didn't work.

问题 Lets say I pull a new image from a hub repository and run it without looking at the contents of the dockerfile. Can the container or image affect my host in any way possible?

I am worried if it will affect the server/host. 回答1: With a default execution of an image, the answer is a conditional no. The kernel capabilities are limited, the filesystem is restricted, the process space is

问题 I'm learning docker right now and I have run into something that's confusing. I started using docker-machine , which was great for creating a local VM and spinning up a server on Digital Ocean. However, I now want to return to a state where the docker commands execue on my local machine so that I can add features, build, and push my docker repo. I know how to change to other machines using docker-machine env , but how do I go back to having no active machine? If I restart docker this happens,
