Create new docker image by:
docker build -f d_in_d* -t maprdocker.lab/mapr:centos61-java7-ecosystem-150515_spy_docker .
Note the binaries in sbin, lib64 are from RH 6.5 (docker build machine) The lib/modules are from RH 6.5 and RH 7.1
On my RH 7.1 vm, I started the docker deamon this way:
docker daemon --insecure-registry=maprdocker.lab --exec-opt native.cgroupdriver=cgroupfs
Then I ran the container as:
docker run --privileged -e DOCKER_DAEMON_ARGS=--insecure-registry=maprdocker.lab -t -i imageName '/bin/bash'
TODO: solve: error: failed to stat /dev/mqueue: No such file or directory ls: /etc/modprobe.d/*.conf: No such file or directory
and
WARN[0000] Udev sync is not supported. This will lead to unexpected behavior, data loss and errors. For more information, see https://docs.docker.com/reference/commandline/cli/#daemon-storage-driver-option
Need to run image on RH 6.5 as well to make sure it works ok there.
