docker - mount a host volume to a container created through Dockerfile -
new docker, , per documentation dockerfile, due portability, not allowed specify host volume mapping. fine, there way map host volume (i in mac, say, home dir /users/bsr /data of ubuntu image) linux container. documentation of docker volume talking docker run, not sure how add volume after creating it.
on linux can mount directory of host system docker container passing
-v /path/to/host/directory:/path/to/container/directory to docker run command.
you can see here in documentation: https://docs.docker.com/userguide/dockervolumes/#mount-a-host-directory-as-a-data-volume
if using boot2docker things more complicated. problem ist boot2docker runs little linux vm start docker. if mount volume described above mount directory of little linux vm.
a workaround described in readme of boot2docker github page using samba share:
