-Arvados can be configured to use "Singularity":https://sylabs.io/singularity/ instead of Docker to execute containers on cloud nodes or a Slurm/LSF cluster. Singularity may be preferable due to its simpler installation and lack of long-running daemon process and special system users/groups. See the "Singularity page in the installation guide":{{ site.baseurl }}/install/singularity.html for configuration details.

h2. Design overview
* Even when using the Singularity runtime, users' container images are expected to be saved in Docker format. Specifying a @.sif@ file as an image when submitting a container request is not yet supported.
* Arvados' Singularity implementation does not yet limit the amount of memory available in a container. Each container will have access to all memory on the host where it runs, unless memory use is restricted by Slurm/LSF.
* The Docker ENTRYPOINT instruction is ignored.
-* Arvados is tested with Singularity version 3.7.4. Other versions may not work.
+* Arvados is tested with Singularity version 3.9.9. Other versions may not work.
