error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory

Question

I am new to docker, and it is my first time meeting such error.

This is my DockerFile

FROM rust:latest as builder
ENV APP mapservice
WORKDIR /usr/src/$APP
COPY . .
RUN cargo install --path .
 
FROM debian:buster-slim
RUN apt-get update && rm -rf /var/lib/apt/lists/*
COPY --from=builder /usr/local/cargo/bin/$APP /usr/local/bin/$APP
#export this actix web service to port 8080 and 0.0.0.0
EXPOSE 8080
CMD ["mapservice"]

And when I run

docker run -it --rm -p 8080:8080 mapservice

I got an error like: mapservice: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory

I have no idea why would I got this error. Perhaps I have my APIKEY hardcoded in the main.rs??Does anyone know how to fix this problem? My laptop is M1pro Mac.

I try to run another sample project with a similar dockerfile, and everything is fine with it. I also tried to deploy it on AWS, which gives me another health check error on 8080. Is it something wrong with my docker file?

Answer 1

This error is because you have copied over the built executable to a new base image which does not have libssl.so.1.1 installed. To fix, you'll need to install the dependency before the CMD step via a package install.

One way to fix this is to install the openssl package by adding RUN apt-get update && apt install -y openssl before the CMD step. You can also dive into installing just the libssl library itself, more info here: https://packages.debian.org/buster/libssl-dev. There are other packages which will also install this dependency. Ultimately the package chosen for installation will depend on your use case.

Answer 2

Using openssl as a dependency like

openssl = { version = "0.10.59", features = ["vendored"] }

did fix it for me
