- Install Oracle Virtual Box on your desktop or laptop. You can then install your own Linux virtual machine with the Singularity rpm, giving yourself root/sudo privilege on that VM. This will allow you to build an image. The solution works for both Windows, Mac and Linux desktop/laptop.
- Even easier than using Virtual Box directly: Use Vagrant. Vagrant uses Virtual Box to spin up VMs, but it's automated and very fast. The advantage to Vagrant is that the OS install does not need to be done – Vagrant downloads preinstalled images, so you can run "vagrant up" and then ssh into your VM in seconds, and use sudo there.
- Similarly, one can install Docker on your desktop or laptop. Then install / pull a Linux Docker container and install Singularity rpm in the container. The rest is the same as above.
- Build what you need in a Docker image and upload to Docker Hub, and on a SLAC Linux host, use command "
singularity pull your_docker_image" to convert and save it as a Singularity image.
