I'd like to run CoreOS (beta) have the contents of /var/lib/docker available on my host, so I can inspect files inside docker container images. This is for local development only.
Let's take Wordpress development as an example: - I run coreos beta in vagrant - mount my app's code inside a container via volumes - the container image installs wordpress core - and also adds plugins via composer (a php package manager)
I'd like to be able to add wordpress core and the plugins in my IDE for debugging.
I've tried mounting nfs via vagrant from host to vbox. When I first run "docker info", /var/lib/docker is created, but is using devicemapper (instead of overlayfs) and somehow manages to eat up all my HDD space in the devicemapper file (and then hang).
Also thought about intalling nfs-server in coreos but that requires a custom build of coreos-vagrant, and I'd like to avoid that.
Any other options? Thanks!
