This seems like zlib related issue. I tried it with Fedora container with newer zlib, and the problem did not manifest.

Can you be more specific, please? Where is the zlib used in this case?

[khardix]

The Z_DATA_ERROR is a zlib error constant that seems to propagate from the native library through node wrapper. Similar issue on FreeBSD and Node 10.3 was solved with upgrade of the bundled zlib.

Node itself bundles zlib in version 1.2.11, CentOS 7 (and the image in question) contains version 1.2.7, so I guess it may be the manifestation of the same issue as above.

I have managed to fix it by updating zlib to 1.2.11. Steps to reproduce:

1. Rebuild zlib from Fedora Rawhide for EPEL 7:

   $ mock -r epel-7 --resultdir epel-7 --rebuild zlib-1.2.11-15.fc30.src.rpm

2. Upgrade build image (here, using podman/buildah):

   #!/usr/bin/bash
   
   sources=(epel-7/zlib{,-devel}-1.2.11-*.x86_64.rpm)
   working=$(buildah from nodejs-10-centos7)
   target=nodejs-10-centos7-zlib
   
   buildah copy "$working" "${sources[@]}" /tmp/zlib/
   buildah run --user=root "$working" yum -y install "${sources[@]/#epel-7//tmp/zlib}"
   buildah commit "$working" "$target"
   
   podman push localhost/"$target" docker-daemon:"$target":local

3. Verify that the application installs cleanly

   $ s2i build https://github.com/sclorg/nodejs-ex.git nodejs-10-centos7-zlib:local testimgnode

Though the magic of git bisect (:heart:) I managed to isolate the fix to a single commit.

Fix inflateInit2() bug when windowBits is 16 or 32.

A windowBits value of 0, 16, or 32 gets the window bits from the
zlib header. However there is no zlib header for 16, or for 32
when the input is gzip. This commit sets the window bits for
inflate to 15 if a gzip stream is detected and windowBits was 16
or 32.

Thanks @khardix upgrading to zlib 1.2.11 worked for me too.

For anyone that needs it I've made a small script that we run inside our gitlab CI for building zlib (and other RPMs) from Fedora rawhide using mmornati/docker-mock-rpmbuilder which we then install inside of our container that inherits from centos/nodejs-10-centos7:latest. The process boils down to:

$ PACKAGE=zlib PACKAGE_VERSION=1.* ARCH=x86_64 TARGET=epel-7 OUTPUT_DIR=./rpm-packages ./build-rpm.sh

COPY ./rpm-packages/ /tmp/rpm-packages/
RUN yum install -y /tmp/rpm-packages/*
