singularity.yaml

# Example to use Singularity instead of containerd & nerdctl
# $ limactl start ./singularity.yaml
# $ limactl shell singularity singularity run -u -B $HOME:$HOME docker://alpine

# Fedora provides Singularity in the default dnf.
# Ubuntu does not seem to provide Singularity in the default apt.
