Build Singularity Containers from Recipes

• Because you do not have administrative privileges, you cannot build a Singularity container from a Singularity recipe file on Cypress.

Build Remotely on the Cloud

• You can build a Singularity container from a recipe on ​Sylabs Cloud.
• Then download the resulting .sif file to Cypress from the cloud with the bash command wget. (See man wget.)

Build on Your Local Machine

• You could build a Linux machine and install Singularity.
• On Windows 11 or Windows 10 version 2004 and higher (Build 19041 and higher)
  • Install Windows Subsystem for Linux, version 2 (WSL 2). See ​Install WSL.
  • Install Singularity. See ​SingularityCE Documentation.
• As an alternative to SingularityCE, on your local machine (Linux or WSL 2) you could install Apptainer.
  • Apptainer will build .sif files compatible with Singularity. See ​ SIF Image Compatibility.
  • See ​ Apptainer Documentation .
• Then upload the resulting .sif file to Cypress from your local machine using scp. (See scp command.)
