for PM-1298 we updated the tc format for containers to allow for mount keyword
e.g
cont centos-pegasus
{
type "singularity"
# URL to image in a docker hub or a url to an existing docker
# file exported as a tar file
#image "gsiftp://bamboo.isi.edu//lfs1/scratch/vahi/docker/centos-base.tar"
image "docker:///rynge/montage:latest"
# optional site attribute to tell pegasus which site tar file
# exists. useful for handling file URL's correctly
image_site "local"
# a url to an existing docker file to build container image from scratch
dockerfile "/URL"
#mount information
mount "/Volumes/Work/lfs1:/shared-data/:ro"
mount "/data1:/shared-data1"
# specify env profile via env option do docker run
profile env "JAVA_HOME" "/opt/java/1.6"
profile env "KARAN" "VAHI"
}
