Dockerfile questions

Testing your solution by building up the docker image with the make build and final make run commands was quite easy and quick.

You are using a base golang image to build the binaries, and then you are running the final binary into the same image:

• What security concerns would you still need to address if you would deploy this service on production?
• How could you reduce the final image size once you already have the built binary?

yes, in future we can use 2 images: one golang image for build binary and second alpine image for other packages, configuration files and etc

[sergripenko]

for reduce image size we can squash multiple layers into one with multi-stage Docker builds and also we can use node-distroless directive when we build image
