Singularity

Official Website
Application container for scientific experiments -- just for us!?
Its internal seems similar to Docker
Supports X11 forwarding out-of-the-box(, and GPU acceleration?)
Can make a container image from a docker image
Faster to initiate container than Docker

Issues?

Each container is contained in a single file, which brings unnecessary duplicated common system files.
- Singularity does not utilize layered container structure like Docker.
- A storage waste from not sharing common packages installed is expected.
Because there is no root ptiviledge in the container out-of-the-box. we cannot use apt-get (yum for Redhat) to install missing packages after building app image.

Solved issues

Cannot convert from a docker image
- it seems that bug was fixed in recent source code @2018.11.
- Can load from local docker registry (w/o HTTPS) from v3.0.2 again Related issue
It seems it still also requires root priviledges or docker priviledges, that could be a security threat...
- It seems not right...! Singularity containers can be run without root or in docker group

It seems Synopsys was already using Singularity as their (desktop workstation) container solution.

Please see Synopsys Container.
