USAGE:

./singularity_build.sh <command> [options] ...

COMMANDS:

- all		setup, build, and install [sudo]
- setup		install dependencies for your distribution [sudo]
- build		configure and make the installation, with optional --prefix
- install	make, and make install [sudo]
- update	[sudo]
- clean		clean Singularity installations
- test		run `make test`

Options:

--prefix/-p  install to specified prefix.
--devel/-d   do specified commands for development version
--sysconfdir specify system config directory for singularity.conf

Examples:

• Install dependencies, setup, build + install

 $ sudo ./singularity_build.sh all

• Build + optional prefix

$ sudo ./singularity_build.sh build --prefix=/my/path

• If you already have the needed dependencies, just install

  $ sudo ./singularity_build.sh install

• Update to the latest release

 sudo ./singularity_build.sh update

• Clean Singularity installations from /my/path

 sudo ./singularity_build.sh clean --prefix /my/path

cloud platforms

With this packer configuration you can generate build instances (images) on different cloud platforms.

googlecompute output will be in this color.

This script can be used outside of Singularity Hub/Singularity Python - currently we aren't using Packer to generate the image because there seems to be an issue with installing Singularity with it. Instead, the image is created interactively, and saved for Singularity Hub. If you get the packer version to work, please let us know!
