The example bootstrap definition files, each called Singularity, are located
in their respectively named folders in this directory. These files can be used
to create new container images on a variety of Linux distributions or become the
basis for customization to build reproducible containers for a specific purpose.
While many of these examples use core mirrors and OS distributions, keep in mind
that you can use a Docker bootstrap to create almost any of them.
If you have a specific scientific (or other) container, we suggest that you consider singularity hub to serve it. If you do not intend to build or use the container, or want to provide a base template, then you might also want to send a pull request to add it here.
If you wish to contribute a definition file that does not fall within one of the folders here, it should go into contrib. In this case, please send a pull request and contribute it to the examples/contribs directory with the format being hyphen ('-') delimited of the following format:
- Base distribution name and version if applicable (e.g. centos7 or ubuntu_trusty)
- Target nomenclature that describes the container (e.g. tensorflow)
- Any relevant version strings to the application or work-flow
- Always end in .def
An example of this:
examples/contrib/debian84-tensorflow-0.10.def
If your contribution is more appropriate for one of the base or template
distributions, then please make a respective folder in the examples
directory, and name the definition file Singularity.
