Proposal: Distroless and Alpine image improvements.

[dojyorin]

I think there are some issues with Dockerfiles in this repository (especially Alpine and Distroless).

And I came up with some solutions and published in my repository and DockerHub.

Quote from my repository:

This project was created to solve the problems faced by deno_docker official images.

• tini is redundant
• Alpine dependent on third-party image
• Using old debian in Distroless (Uses 11, latest is 12)

• For tini, explicitly told to use tini which integrated in Docker, and removed it from Dockerfile.
• For Alpine, resolve dependencies by copy glibc from Distroless.

If my approach is of positive to everyone, I would like to contribute to this repository.

But since I'm beginner, I'd like to hear everyone's opinions first.

About removing tini, on one hand it makes a cleaner Dockerfile/image, but OTOH all your users have to remember to use --init and it's one more barrier to a smooth experience, and removing it now would be a breaking change IMO. Having up to date alpine images would be great though :).

Not sure if it helps, but this works for me:

FROM denoland/deno
WORKDIR /app
ADD . /app
RUN deno compile --allow-net server.ts

FROM gcr.io/distroless/cc-debian12:nonroot
COPY --from=0 /app/server /home/nonroot/server
ENTRYPOINT ["./server"]

@dojyorin If you would like to PR support for using alpine:latest with glibc from distroless and the existing tini setup, I think that would be a PR we could accept.

Removing tini would be a different discussion, but our Alpine support could definitely be improved.
