ronmi/mingo repository overview

Automatically build minimal image for running Go binaries, based on Debian stable.

⁠Intro

FROM golang AS builder
RUN mkdir /src /app /app/data
WORKDIR /src
RUN --mount=type=bind,target=. go build -o /app/my-app

FROM ronmi/mingo
COPY --from=builder /app /app
WORKDIR /app
ENTRYPOINT ["/app/my-app"]

YOU CAN NOT RUN ANY COMMAND at final stage.

⁠Pros

• Really small (~2mb)
• No executables in it, increases security
• Debian based, one of the most stable distro on earth

⁠Cons

• Hard to extend (no apt/dpkg tools in it)
• Hard to debug (no debugger/less/vim/... in it)
• You can't even mkdir in it (lmao)

⁠What's in it

• libc6
• ca-certificates
• tzdata (use it with volumes like -v /etc/timezone:/etc/timezone:ro -v /etc/localtime:/etc/localtime:ro)

That's all.
