	Singularity is a software that ~~enables execution of containers~~ as a ~~job on~~ a ~~cluster.~~		Singularity lets users run applications and jobs inside a Linux container. This allows for applications that were built to run on a different distribution of Linux or have specific software dependencies that are not compatible with our cluster systems to run. Applications from the [https://singularity-hub.org/ Singularity Hub] or [https://hub.docker.com Docker Hub] can run without needing to install anything.

			== Usage ==
			Singularity is available on on ARC as a loadable module. To get started, load the Singularity module:
			module load singularity

			Singularity can be used interactively. If you wish to enter a specific environment provided by a container, such as Ubuntu:
			singularity shell docker://ubuntu

Created page with "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"..."

New page

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>
