# How to create scripts/docker-entrypoint.sh.patch
# 1. Download the original file:
#    wget https://github.com/docker-library/mongo/raw/master/5.0/docker-entrypoint.sh
#    ( wget https://github.com/docker-library/mongo/raw/b5c0cd58cb5626fee4d963ce05ba4d9026deb265/5.0/docker-entrypoint.sh )
# 2. Make a copy of it:
#    cp docker-entrypoint.sh docker-entrypoint-patched.sh
# 3. Add required modifications to docker-entrypoint-patched.sh
# 4. Create patch:
#    diff -u docker-entrypoint.sh docker-entrypoint-patched.sh > scripts/docker-entrypoint.sh.patch
# 5. Clean up:
#    rm docker-entrypoint.sh docker-entrypoint-patched.sh
