Warning

Turing does not support Docker. Docker containers MUST be run using Apptainer.

Running public Docker containers using Apptainer

Apptainer can directly run containers available on DockerHub. For example, to run the sylabsio/lolcow:latest container, first run 

module load apptainer
then use the following command:

$ apptainer  run --userns  docker://sylabsio/lolcow:latest
