Docker Cookbook - Second Edition

Getting ready

• Before we begin, ensure that the Docker daemon is running and has access to the gcc and scratch images. Also, ensure that there is a clone of https://github.com/docker-cookbook/multistage.git and that the repository contains both src/app.c and Dockerfile.
• The content of src/app.c should be as follows:

#include <stdio.h>void main(){    printf("This is a Docker multistage build demo\n");}

• The content of Dockerfile should be as follows:

FROM gcc:7.2 AS builderCOPY src /srcRUN gcc -static -o /src/app /src/app.c && strip -R .comment -s /src/appFROM scratchCOPY --from=builder /src/app .CMD ["./app"]
