feat: add Dockerfile.dev (#7496)
We have shifted our local testing from running Lodestar binary to using Kurtosis which requires locally built docker image. The current Dockerfile is optimized for production release and the build time is too long for rapid iteration during testing. Adding Dockerfile.dev which is a stripped down version of Dockerfile and it - minimizes number of installs and builds - ~~does not write git data~~ - faster image building - larger image size by not pruning unnecessary fs - is recommended to build and run image locally Following are the comparison of Dockerfile and Dockerfile.dev on my local machine fresh/uncached. It shows ~60% or 8 minute reduction in build time. Dockerfile: ``` NC@Chainsafe % docker build -f Dockerfile -t ensi321/lodestar:production .
