Removing Container Images

To maintain your system it is good practice remove container images that are no longer needed. For example, the lolcow container image (lolcow_latest.sif) occupies 84 Mb of system space.

To delete an image use:

rm CONTAINER_NAME.sif

If needed in the future it can easier be pulled again.

You can also clean your system cache (~/.singularity/cache/) using:

singularity cache clean

To list Singularity container images use:

singularity cache list -v
