Singularity Run or Execute Command as the Same as Docker Run
I Am Working Under a University's Hpc System, Which Has Only Singularity Installed and Without Docker. I Want to Run an Already Singularity-Pulled Docker Image...
I am working under a university's HPC system, which has only singularity installed and without docker. I want to run an already singularity-pulled docker image (julia_adfem_v1.sif). The original command for the docker environment is docker run -ti kailaix/adcme . What's it for singularity?
I have tried something like singularity exec ./julia_adfem_v1.sif kailaix/adcme but not sucessful.

From your question, there are two different images
- julia_adfem_v1.sif (an image that is already there locally)
- kailaix/adcme (an image from docker hub)
Let me talk about case 1:
Note: julia_adfem_v1.sif is a container file.
To run:
singularity run julia_adfem_v1.sif
To exec with some command:
singularity exec julia_adfem_v1.sif echo "It's working!"
Let me talk about case 2:
Note: kailaix/adcme is a docker hub image file.
To run:
singularity run docker://kailaix/adcme
To exec with some command:
singularity exec docker://kailaix/adcme echo "It's working"
If you want to run a container from the docker registry, you can use the following:
singularity run docker://kailaix/adcme
If you want to exec something on the container, you can use:
singularity exec docker://kailaix/adcme echo "test"
