feat: port Containerfile to use Vib's recipe

[kbdharun]

Changes

This PR ports the Containerfile to be generated via a Vib recipe file. (cc @matbme) [I have tested the generated image at https://github.com/kbdharun/Differ/pkgs/container/differ.]

Details

Current Containerfile:

FROM docker.io/golang:1.21-alpine
LABEL maintainer="Mateus Melchiades"

WORKDIR /home/user

# Install dependencies
RUN apk add --update gcc musl-dev sqlite make

# Copy project files and build
COPY main.go go.mod go.sum go.work Makefile /home/user/
COPY core /home/user/core/
COPY diff /home/user/diff/
COPY types /home/user/types/
COPY vendor /home/user/vendor/
RUN make

# Cleanup
RUN rm -rf main.go go.mod go.sum go.work Makefile core/ types/ vendor/

EXPOSE 8080

CMD ["/home/user/differ"]

New Vib generated Containerfile:

# Stage: build
FROM docker.io/golang:1.21-alpine AS build
LABEL maintainer='Mateus Melchiades'
EXPOSE 8080/
ADD includes.container /
ADD sources /sources
RUN mkdir /home/user && cp /sources/init/main.go /home/user/ && cp /sources/init/go.mod /home/user/ && cp /sources/init/go.sum /home/user/ && cp /sources/init/go.work /home/user/ && cp /sources/init/Makefile /home/user/ && mv /sources/init/core /home/user/core/ && mv /sources/init/diff /home/user/diff/ && mv /sources/init/types /home/user/types/ && mv /sources/init/vendor /home/user/vendor/ && rm -rf /sources/init
RUN apk add gcc musl-dev sqlite make
RUN cd /home/user && make
RUN rm -rf main.go go.mod go.sum go.work Makefile core/ types/ vendor/
CMD ["/home/user/differ"]

Note

WORKDIR instruction is currently not supported in Vib; I haven't tested COPY instruction in Vib outside of moving files between stages (if that works, I am open to optimizing the RUN command moving all the assets. Also, I tried using the make built-in module but it didn't work while testing so switched to shell type.
