standard_init_linux.go:228: exec user process caused: no such file or directory on CGO project

I have a Go service that references a C library, and I am getting the following error when trying to run my docker image:

standard_init_linux.go:228: exec user process caused: no such file or directory

This is not a duplicate of https://stackoverflow.com/questions/51508150/standard-init-linux-go190-exec-user-process-caused-no-such-file-or-directory as I do not have an entrypoint shell script with CR line endings. Some others on this site suggested setting CGO_ENABLED=0 at compile time, but I of course can't do that as this is a CGO project.

The C library is installed under /usr/local/lib/sgp4 in the directories Linux/IFORT and Linux/GFORTRAN, which contain a bunch of .so files.

An environment variable LD_LIBRARY_PATH is set to /usr/local/lib/sgp4/Linux/IFORT.

Within my project, there is a set of wrapper .h files, and the CGO comments as follows:

My Dockerfile is as follows:

FROM [redacted]/alpine-base:3.17

RUN apk update && \
    apk add curl jq

COPY etc/cfg/propagator.properties /usr/local/[redacted]/etc/cfg/
COPY bin/sgp4 /usr/local/[redacted]/bin/sgp4
COPY propagator/wrappers /usr/local/[redacted]/bin/wrappers

# Download library files
RUN mkdir -p /usr/local/sgp4/lib
RUN curl --output /usr/local/sgp4/lib/SGP4.tar [redacted]/SGP4.tar
RUN tar -xf /usr/local/sgp4/lib/SGP4.tar -C /usr/local/sgp4/lib
RUN rm /usr/local/sgp4/lib/SGP4.tar
RUN export LD_LIBRARY_PATH=/usr/local/sgp4/lib/Linux/IFORT

RUN chmod a+rx /usr/local/[redacted]/bin/sgp4

RUN addgroup [redacted] && adduser -D -H -G [redacted] [redacted]
USER [redacted]:[redacted]

HEALTHCHECK NONE

ENTRYPOINT ["/usr/local/[redacted]/bin/sgp4", "-config-file-path=/usr/local/[redacted]/etc/cfg/propagator.properties"]

Wondering if my library files contained CR line endings, I tried adding these commands to my Dockerfile, but no luck:

RUN for filey in $(find /usr/local/sgp4/lib/Linux -type f); do echo $filey; sed -i 's/\r$//g' $filey; done

RUN for filey in $(find /usr/local/sgp4/lib/Linux -type f); do echo $filey; tr -d \r < $filey > tmp.so; mv tmp.so $filey; done

Note: I compiled the binary on debian, but am constrained to using Alpine for the Docker image. Issues I encountered when compiling are discussed here: https://stackoverflow.com/questions/76717432/cgo-compiler-error-missing-library-links-librt-so-1-not-found

A way to solve the runtime issue would be to switch to a glibc-based Docker image such as Debian slim or jeanblanchard/docker-alpine-glibc, because your Go binary and its CGO dependencies were built against glibc.

Using jeanblanchard/alpine-glibc, since it is still based on Alpine:

FROM jeanblanchard/alpine-glibc:3.18

RUN apk update && \
    apk add curl jq

COPY etc/cfg/propagator.properties /usr/local/[redacted]/etc/cfg/
COPY bin/sgp4 /usr/local/[redacted]/bin/sgp4
COPY propagator/wrappers /usr/local/[redacted]/bin/wrappers

# Download library files
RUN mkdir -p /usr/local/sgp4/lib
RUN curl --output /usr/local/sgp4/lib/SGP4.tar [redacted]/SGP4.tar
RUN tar -xf /usr/local/sgp4/lib/SGP4.tar -C /usr/local/sgp4/lib
RUN rm /usr/local/sgp4/lib/SGP4.tar
ENV LD_LIBRARY_PATH=/usr/local/sgp4/lib/Linux/IFORT

RUN chmod a+rx /usr/local/[redacted]/bin/sgp4

RUN addgroup [redacted] && adduser -D -H -G [redacted] [redacted]
USER [redacted]:[redacted]

HEALTHCHECK NONE

ENTRYPOINT ["/usr/local/[redacted]/bin/sgp4", "-config-file-path=/usr/local/[redacted]/etc/cfg/propagator.properties"]

This base image maintains the small footprint of Alpine but also has the compatibility of glibc, which should make it compatible with your CGO binary.

Switching to this Dockerfile and rebuilding your image should solve the "exec user process caused: no such file or directory" error, as well as the "required file not found" error from ldd.
