# Build Singularity

## Summary

This is a build container that generates installable singularity packages for
singularity v3.X.X. The container will output a deb and rpm in the current
directory.

## Known Bugs

Some versions of singularity contain the character 'v', such as v3.0.0. The
container will have to be rebuilt with the following statement modified:

```sh
curl -L -o singularity-${VERSION}.tar.gz \
  https://github.com/sylabs/singularity/releases/download/v${VERSION}/singularity-${VERSION}.tar.gz
```

## Usage

```sh
sudo singularity build build-singularity.sif build-singularity.def

./build-singularity.sif {version}

./build-singularity.sif 3.6.2
```
