Solution to failed to run custom build command for `openssl-sys v0.9.104`

 When upgrading "reqwests" library I got the following error on docker build:

#18 182.8 The following warnings were emitted during compilation:

#18 182.8 

#18 182.8 warning: openssl-sys@0.9.104: Could not find directory of OpenSSL installation, and this `-sys` crate cannot proceed without this knowledge. If OpenSSL is installed and this crate had trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the compilation process. See stderr section below for further information.

Could not find the solution after googling, but I tried the obvious solution, install openssl-dev into the docker image:

FROM rust:1.82-alpine AS builder

RUN apk add --no-cache openssl-dev

After this I got the following error:

x86_64-alpine-linux-musl/bin/ld: cannot find -lssl: No such file or directory

x86_64-alpine-linux-musl/bin/ld: cannot find -lcrypto: No such file or directory

And the fix for this was adding the openssl-libs-static:

FROM rust:1.82-alpine AS builder

RUN apk add --no-cache openssl-dev openssl-libs-static

 

Fixed
