Scope using LD_PRELOAD fails for redis glibc container

[seanvaleo]

Steps To Reproduce

Scoping following container fails Dockerfile.redis:

FROM redis:6

COPY --from=cribl/scope:1.3.2 /usr/local/bin/scope /usr/local/bin/scope
RUN /usr/local/bin/scope extract /usr/local/lib/

ENV LD_PRELOAD="/usr/local/lib/libscope.so"

# Expose Redis port
EXPOSE 6379

# Start Redis server
CMD ["redis-server"]

docker build --file Dockerfile.redis --tag myredis:latest .
docker run myredis:latest

There is no libscope.so in the redis process above

Scoping same container using different image works fine:

Dockerfile.alpine:

FROM redis:6-alpine

COPY --from=cribl/scope:1.3.2 /usr/local/bin/scope /usr/local/bin/scope
RUN /usr/local/bin/scope extract /usr/local/lib/

ENV LD_PRELOAD="/usr/local/lib/libscope.so"

# Expose Redis port
EXPOSE 6379

# Start Redis server
CMD ["redis-server"]

docker build --file Dockerfile.alpine --tag myredisalpine:latest .
docker run myredisalpine
