Unable to build Alpine Docker image

[jenstroeger]

Hi, with the following Dockerfile

FROM alpine:3.21

RUN apk update && apk add curl postgresql17-dev

RUN curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- --default-toolchain nightly -y
ENV PATH="/root/.cargo/bin:${PATH}"

RUN cargo install cargo-pgrx  

I’m unable to build cargo-pgrx

Am I missing a dependent package, or what’s happening here?

Seems to be a duplicate of/related to issue #2009.

However, even with installing

RUN apk update && \
  apk add git curl gcc openssl && \
  apk add postgresql17-dev file-dev openssl-dev libcrypto3 readline-dev zlib-dev libxml2-dev libxml2-utils libxslt-dev

as indicated here and then

RUN cargo install cargo-pgrx --version "0.13.1" --locked

I get linker errors:

215.3   = note: /usr/lib/gcc/x86_64-alpine-linux-musl/14.2.0/../../../../x86_64-alpine-linux-musl/bin/ld: cannot find -lssl: No such file or directory
215.3           /usr/lib/gcc/x86_64-alpine-linux-musl/14.2.0/../../../../x86_64-alpine-linux-musl/bin/ld: cannot find -lcrypto: No such file or directory
215.3           collect2: error: ld returned 1 exit status

I can’t quite (yet) figure out which packages I need to install to provide these libs… 🤔 (Perhaps related issue #340 for Alpine pkgs.)

• https://pkgs.alpinelinux.org/contents?file=libssl.so&path=&name=&branch=edge&repo=&arch=x86_64
• https://pkgs.alpinelinux.org/contents?file=libcrypto.so&path=&name=&branch=edge&repo=&arch=x86_64

Probably openssl-dev.

[jenstroeger]

Probably openssl-dev.

@usamoi, that’s already in my list of packages above 🤔

Ha, I know why now. You need to add RUSTFLAGS="-Ctarget-feature=-crt-static" to your environment variable, since rustc installed by rustup would try to link everything statically.

For Alpine Linux, using the package manager to install Rust might be better than using rustup. I think rustc provided by the package manager will patch this behavior.

I think that worked:

...

#11 203.1   Installing /root/.cargo/bin/cargo-pgrx
#11 203.1    Installed package `cargo-pgrx v0.13.1` (executable `cargo-pgrx`)
#11 DONE 203.3s

I actually tried to

RUN apk add rust rustup cargo

but that didn’t work — I couldn’t make rustup run.

Sounds like the original problem has been resolved.
