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 (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

1. julia_adfem_v1.sif (an image that is already there locally)
2. 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"
