	gcc-5.5           matlab/R2018a    trimmomatic-0.33
	gcc63/mpich-3.2   matlab/R2018b    udocker/1.1.3

	[user@pauli02 ~]$ module load udocker

The udocker almos the same way as the command docker, the big difference is that it run on user space and doesn't require special privileges to run. The docker hub repository is available and the user is able to upload end load images from the docker hub repository and his own images also.
