Use 'git clone --depth 1' to reduce docker image size from 1GB to 500MB

I am not sure if there is a specific reason to clone the full repository inside Dockerfile.

If not, with git clone --depth 1, the docker image size can be reduced from 1000MB to 500MB.

This will create a shallow clone, which is primarily useful for builds, not development.

It is a workaround for users who want to run a development build, the whole idea of including the repo needs rehinking. Thanks for your contribution - it'll be a great additional until I can solve this more cleanly.

Perhaps the solution is to have two different docker images?

Or, a different tag - e.g. iris:latest, iris:develop

I thought about this - there are Multistage Docker builds. Perhaps this could be an option to reduce the image size further in future releases, and also provide an additional developer image. I have recently added a Multistage Dockerimage for asciiflow, have a look at the Dockerfile here, which includes multiple FROM tags. The final alpine nginx image is 19 MB.

Just thinking..
