On: How to start a Go project in 2023

[cratermoon]

Note that statically linked go binaries work in a docker image from scratch. This can be created with a multi-stage build where the builder image uses whatever OS you prefer, with any required packages. A build line such as

    RUN CGO_ENABLED=0 go build -o mybin -ldflags '-extldflags "-static"' -tags timetzdata

And the second stage like

    FROM scratch
    COPY --from=app-builder mybin mybin
    ENTRYPOINT ["/mybin"]

The builder can create users and groups, and the final image can import necessary certs like so:

    COPY --from=alpine:latest /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/
