Originally created by @DerVerruckteFuchs on GitHub (May 29, 2022).

I've attempted to build vaultwarden on Alpine Linux 3.15 and 3.16, and the resulting binary segfaults when trying to run it. It seems to be a build environment issue with OpenSSL. The build environment fix (using RUSTFLAGS=-C target-feature=-crt-static) from the link worked for me. I used env RUSTFLAGS=-C target-feature=-crt-static cargo build..., and I have a build that runs successfully. It would probably be a good idea to set this somewhere for Alpine Linux builds.

We do not use alpine as a build environment, so no need to add this. Maybe adding it to the wiki is an option.
