Starting from docker 17.06, you can mount NFS shares to the container directly when you run it, without the need of extra capabilities export NFS_VOL_NAME=mynfs export NFS_LOCAL_MNT=/mnt/mynfs export NFS_SERVER=my.nfs.server.com export NFS_SHARE=/my/server/path export NFS_OPTS=vers=4,soft docker run –mount \ “src=$NFS_VOL_NAME,dst=$NFS_LOCAL_MNT,volume-opt=device=:$NFS_SHARE,\”volume-opt=o=addr=$NFS_SERVER,$NFS_OPTS\”,type=volume,volume-driver=local,volume-opt=type=nfs” \ busybox ls $NFS_LOCAL_MNT Alternatively, you can create the volume before the container: docker volume create \ … Read more
First of all, docker volumes or bind mounts behave like linux mounts. If the host volume/mount exists and contains files it will “override” whatever is in the container. If not the container files will be mirrored onto the host volume/mount and the container folder and the host will be in sync. In both cases editing … Read more
Yes, Docker is preventing you from mounting a remote volume inside the container as a security measure. If you trust your images and the people who run them, then you can use the –privileged flag with docker run to disable these security measures. Further, you can combine –cap-add and –cap-drop to give the container only … Read more

Specifically: This got easier recently since Docker finally merged a patch which will be showing up in docker-1.7 (We have been carrying the patch in docker-1.6 on RHEL, CentOS, and Fedora). This patch adds support for “z” and “Z” as options … Read more
It is not possible to use the VOLUME instruction to tell docker what to mount. That would seriously break portability. This instruction tells docker that content in those directories does not go in images and can be accessed from other containers using the –volumes-from command line parameter. You have to run the container using -v … Read more
There are a couple ways you can do this. The simplest way to do so is to use the dockerfile ADD command like so: ADD . /path/inside/docker/container However, any changes made to this directory on the host after building the dockerfile will not show up in the container. This is because when building a container, … Read more
