Failed to Build a Docker Image with the Go Binding

[wjkoh]

Hi Alex,

I'd like to build a Docker image for our Go server that uses https://github.com/mattn/go-sqlite3 and https://github.com/asg017/sqlite-vec. I'm having a hard time building a static or dynamically linked binary with CGO.

I tried the following Dockerfile that does just build.

FROM golang:1.23 as builder

ENV CGO_ENABLED=1

WORKDIR /app
COPY go.mod go.sum ./
RUN go mod download && go mod verify

COPY . .
RUN go build -o server ./cmd/wine

FROM gcr.io/distroless/static-debian12

COPY --from=builder /app/server /
CMD ["/server"]

I got the following error. It looks like SQLite amalgamation from mattn/go-sqlite doesn't work for the extension.

Step #0: Step 8/11 : RUN go build -o server ./cmd/wine
Step #0:  ---> Running in 154b0c8309b1
Step #0: # github.com/asg017/sqlite-vec-go-bindings/cgo
Step #0: In file included from /go/pkg/mod/github.com/asg017/[email protected]/cgo/lib.go:4:

Step #0:     4 | #include "sqlite3ext.h"
Step #0:       |          ^~~~~~~~~~~~~~
Step #0: compilation terminated.

Thus, I tried to go around the amalgamation and use the system-wide SQLite3 library for compiling and linking as follows:

FROM golang:1.23 as builder

ENV CGO_ENABLED=1

RUN apt-get update \
 && DEBIAN_FRONTEND=noninteractive \
    apt-get install --no-install-recommends --assume-yes \
      build-essential \
      libsqlite3-dev

WORKDIR /app
COPY go.mod go.sum ./
RUN go mod download && go mod verify

# RUN go get github.com/mattn/go-sqlite3
# RUN go get github.com/asg017/sqlite-vec-go-bindings/cgo

COPY . .
ARG CMD
RUN go build -tags libsqlite3 -o server ./cmd/${CMD}

FROM gcr.io/distroless/static-debian12

COPY --from=builder /app/server /
COPY --from=builder /app/vectors.db /
CMD ["/server"]

This also fails with the following errors.

Could you please advise or provide a simple Dockerfile example? Thanks!
