When using the linux binary I am unable to run teller-cli on an alpine based image.

$  docker run -it alpine

I can confirm the the issue is related to missing glibc.

I have been able make progress using https://github.com/sgerrand/alpine-pkg-glibc

Using the following Dockerfile I have been able to build and use Teller on alpine.

FROM rust:alpine

ARG GLIBC_VERSION=2.34-r0
ARG TELLER_VERSION=2.0.7

RUN wget -q -O /etc/apk/keys/sgerrand.rsa.pub https://alpine-pkgs.sgerrand.com/sgerrand.rsa.pub && \
   wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/${GLIBC_VERSION}/glibc-${GLIBC_VERSION}.apk && \
   wget https://github.com/sgerrand/alpine-pkg-glibc/releases/download/${GLIBC_VERSION}/glibc-bin-${GLIBC_VERSION}.apk && \
   apk --allow-untrusted add glibc-${GLIBC_VERSION}.apk --force-overwrite && \
   apk --allow-untrusted add glibc-bin-${GLIBC_VERSION}.apk --force-overwrite 

RUN apk add openssl-dev protoc git curl musl-dev
RUN git clone https://github.com/tellerops/teller.git
RUN sed -i 's/\.with_native_roots()/\.with_native_roots()?/g' teller/teller-providers/src/providers/google_secretmanager.rs
RUN cd teller/teller-cli && RUSTFLAGS="-Ctarget-feature=-crt-static" cargo install --path . 
RUN cp /usr/local/cargo/bin/teller /usr/local/bin/teller

There are a few things here.

I cannot build the project currently, I needed to apply a fix for the above issue.

We also need to use glibc-for-alpine, as I was not able to get things to run without it.

The project itself needed to be statically linked linked during the ubild process with the rust flag.
