Singularity is a software that enables execution of containers as a job on a cluster.
Running a Container
TODO
Adding Packages to a Docker Image
- Build a "Sandbox" of the dockerhub image -- we'll use the docker centos:7.6.1810 image as an example:
singularity build --sandbox /tmp/centos/ docker://centos:7.6.1810
- Modify the image -- add the emacs editor into the image:
- Note the "-f" which means to use fakeroot which gives root privilege inside the conainer (so you can use yum install)
singularity run -f -w /tmp/centos/ yum -y install emacs
- Package up the sandbox into a singularity 1 file image:
singularity build -f centoswithemacs.simg /tmp/centos/
- Now you can use the container image in a job (replacing <your computation> with the program inside the container that you want to run):
singularity run centoswithemacs.simg <your computation>
