Improved the script from https://jpetazzo.github.io/2015/01/13/docker-mount-dynamic-volumes/ to work with more scenarios. Save this file in the same directory as nsenter (https://github.com/jpetazzo/nsenter) and chmod +x it. This allows you to mount a host path on a running container. You may have to adjust the ownership of the mounted directory…
#!/bin/bash -e
# Based on https://jpetazzo.github.io/2015/01/13/docker-mount-dynamic-volumes/
SCRIPT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
[[ $# -eq 3 ]] || {
echo "Usage: $0 <container_name_or_id> <host_path> <container_path>" 1>&2
exit 1
