install.duckdb.org could support specific versions

[jelder]

I would like to be able to install a specific version of DuckDB CLI more easily. My use case is that I'm Dockerizing a script that talks to MotherDuck, which doesn't yet support the latest version (1.3.2).

The workaround I'm using is to modify the script before running it:

RUN curl https://install.duckdb.org | sed 's/VER=.*$/VER=1.3.1/' | sh

This is obviously quite fragile. I could just use the direct download URL, but since my development machine's architecture doesn't necessarily match that of the production environment, I would have to reproduce the Arm/Intel check.

Some "curl | bash" installers allow passing arguments via env vars, for example:

RUN VER=1.3.1 https://install.duckdb.org | sh

Alternatively, it would be nice if there were official Docker images for the CLI and libraries.

Hi @jelder, thanks for the suggestion! This is currently not planned for the installer but we may consider it in the future.

For your use case, the (third-party) duckdb-version-manager may be an interesting project. See https://github.com/NiclasHaderer/duckdb-version-manager

It looks like somebody went ahead and did this anyway, because this now works:

curl install.duckdb.org | DUCKDB_VERSION=1.3.2 bash

Thanks, indeed this is part of the installer. I'll add it to the documentation.
