` error: failed to run custom build command for `openssl-sys v0.9.67`

Question

I am building my cargo docker file. It used to work now it doesn't.

I am receiving this error: error: failed to run custom build command for `openssl-sys v0.9.67

I did multiple things based on my multiple digging:

brew install openssl

brew install pkg-config

brew install perl

I added the below in my dependencies in the cargo.toml as well

openssl-sys = "0.9"
openssl = { version = "0.10.33", features = ["vendored"] }

I even added the below on my.profile

export PKG_CONFIG_PATH="/usr/local/opt/openssl@3/lib/pkgconfig"

Still not working. The error only shows during the docker build run.

---here's the error---

---below is the my docker file---

FROM rust:slim
COPY . /build-xxx/
RUN cd /build-xxx/ && rustup default nightly && rustup update && cargo build --release
LABEL Name=XXX Version=0.0.1
EXPOSE 8000
ENV ROCKET_ENV=stage

CMD ["/build-xxx/target/release/xxx"]

Answer 1

Since my error is only happening in the docker build, I updated dockerfile and add the dependencies (build-essential checkinstall zlib1g-dev) required for the OpenSSL.

I changed my docker file to the one below, and it works!

FROM rust:slim
RUN apt-get update && apt-get install -y \
build-essential checkinstall zlib1g-dev -y
COPY . /build-xxx/
RUN cd /build-xxx/ && rustup default nightly && rustup update && cargo build --release
LABEL Name=XXX Version=0.0.1
EXPOSE 8000
ENV ROCKET_ENV=stage
CMD ["/build-xxx/target/release/xxx"]
