SimpleElastix docker image size

[sagarr]

Hi.

Sorry for raising it as an issue, but when I build docker image the size becomes 9.66 GB, Do you know what was your docker image size for elastix when you build it?

[romangrothausmann]

No, the builder image is about 1GB and the final image only about 200MB, see:

Thanks for the reply, is there any special docker build command to run.
I ran below command:
docker build --tag img-reg .
