Attempted on both Alpine and debian and couldn’t get it to work. Here are complete Dockerfiles to test with:

FROM rust:alpine AS builder

RUN apk add --no-cache musl-dev unixodbc-static psqlodbc sqliteodbc

WORKDIR /src
ADD https://github.com/pacman82/odbc2parquet/archive/refs/heads/main.zip .
RUN unzip main.zip && cd odbc2parquet-main && cargo build --release

ENTRYPOINT ["/src/odbc2parquet-main/target/release/odbc2parquet"]

FROM rustlang/rust:nightly-bookworm-slim AS builder

RUN apt-get update -qq && 
    apt-get install -y unixodbc-dev && 
    rm -rf /var/lib/apt/lists/*


WORKDIR /src
ADD https://github.com/pacman82/odbc2parquet/archive/refs/heads/main.zip .
RUN unzip main.zip && cd odbc2parquet-main && cargo build --release

FROM debian:bookworm-slim AS runner
RUN apt-get update -qq && 
    apt-get install -y unixodbc odbc-postgresql && 
    rm -rf /var/lib/apt/lists/*

COPY --from=builder /src/odbc2parquet-main/target/release/odbc2parquet /usr/local/bin/
ENTRYPOINT ["/usr/local/bin/odbc2parquet"]

Then both list-data-sources and list-drivers came out empty.

Or to get simpler:

FROM debian:bookworm-slim AS runner
RUN apt-get update -qq && 
    apt-get install -y unixodbc odbc-postgresql && 
    rm -rf /var/lib/apt/lists/*

ENTRYPOINT ["/usr/bin/odbcinst", "-j"]

Also returns empty. (including equivalent in Alpine)

Do I have to manually modify the /etc/odbcinst.ini file with full shared object paths? – Is there an automated way of doing this?
