Reduce the size of Docker image #26

Open utkarsh-1905 opened 1 year ago

utkarsh-1905 commented 1 year ago

In the previous release, the docker image was built on top of the scratch image and worked fine. But after committing 599ee682edc6b921a2743f00e50307360443ec24, the image built using the previous docker file shows an invalid pointer dereference error, but it is working fine on the full-size go-alpine image.

Image size increased from 15MB -> 450MB
