Using Docker

Some initial tests
I installed Docker on my Macbook, it was quite easy following the directions on the <html><a href='https://www.docker.com/' target='_blank'>Docker website</a></html>.
I played around a little and located an SLC docker image. In a fresh terminal:
->boot2docker init ->boot2docker start ->export DOCKER_TLS_VERIFY=1 ->export DOCKER_HOST=tcp://192.168.59.103:2376 ->export DOCKER_CERT_PATH=/Users/childers/.boot2docker/certs/boot2docker-vm ->docker search slc6 NAME DESCRIPTION STARS OFFICIAL AUTOMATED cern/slc6-base Scientific Linux CERN 6 image ready to use... 2 cern/slc6-lite Lightweight CERN Scientific Linux 6 image 1 cmssw/slc6-vanilla 0 lvarin/slc6_vcs Personal slc6 image for VCS 0 asgc/slc65 Image forked from cern/slc6-base 0 lvarin/slc6_64 Base SLC6 image, no modifications from the... 0 acasajus/slc65 0 anaderi/slc6-devtoolset_1.1 0 cmssw/slc6-externals 0 -> docker pull cern/slc6-base Pulling repository cern/slc6-base 3d85e4d2d936: Download complete beca1e02f1eb: Download complete 79924a46c804: Download complete Status: Downloaded newer image for cern/slc6-base:latest -> docker pull cern/slc6-base:6.5 -> docker images REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE cern/slc6-base 6.6 3d85e4d2d936 12 weeks ago 911.1 MB cern/slc6-base latest 3d85e4d2d936 12 weeks ago 911.1 MB cern/slc6-base 6.5 79924a46c804 6 months ago 402 MB -> docker run cern/slc6-base:6.5 uname -a Linux f4eea7db246b 3.16.7-tinycore64 #1 SMP Tue Dec 16 23:03:39 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
As a test I installed ROOT via yum into the image. The first command here starts an interactive container.
-> docker run -i -t cern/slc6-base:6.5
[root@19035251353f /]# yum install root.x86_64

.
[root@19035251353f /]# root -b

Now I have my own SLC6.5 container with ROOT 5.34 installed.
Next I played with trying to run a root script so I made one:
mkdir vlocal vim vlocal/root_test.C
- | root_test.C
#include <string> #include <iostream> int root_test(void){ string test = "Hello World"; std::cout << test << "\n"; return 0; }
Then I wanted my container to mount my local directory and use this file:
-> docker run --volume=$PWD/vlocal:/vcont jtchilders/slc65:root534 root -b -q /vcont/root_test.C
