Singularity - Tool execution using the HPC-friendly container technology Singularity is now supported. Custom containers can be specified by the Galaxy admin on a per job destination basis or standardized containers corresponding to Conda requirements can be built or downloaded automatically using the mulled toolkit built into Galaxy (just like is possible for Docker). For more information checkout presentation at http://jmchilton.github.io/writing/gcc2017slides/biocontainers.html from the 2017 Galaxy Community Conference.
