Error using Oracle Instant Client Docker image - linux

Question

our app is nodejs based and needs to query Oracle DB, so we install NPM oracledb package. So our Docker image is based on oracle instant client, the Docker file looks like following:
FROM frolvlad/alpine-glibc
RUN apk update && apk add libaio
COPY instantclient_12_1.zip ./
RUN unzip instantclient_12_1.zip
RUN mv instantclient_12_1/ /usr/lib/
RUN rm instantclient_12_1.zip
RUN ln /usr/lib/instantclient_12_1/libclntsh.so.12.1 /usr/lib/libclntsh.so
RUN ln /usr/lib/instantclient_12_1/libocci.so.12.1 /usr/lib/libocci.so
RUN ln /usr/lib/instantclient_12_1/libociei.so /usr/lib/libociei.so
RUN ln /usr/lib/instantclient_12_1/libnnz12.so /usr/lib/libnnz12.so
ENV ORACLE_BASE /usr/lib/instantclient_12_1
ENV LD_LIBRARY_PATH /usr/lib/instantclient_12_1
ENV TNS_ADMIN /usr/lib/instantclient_12_1
ENV ORACLE_HOME /usr/lib/instantclient_12_1
RUN apk add nodejs npm
RUN mkdir -p /var/app
WORKDIR /var/app
ADD package.json /var/app
COPY . /var/app
CMD ["npm","start"]
But when our app starts using 'oracledb' NPM package, it got following error:
init() error: DPI-1047: Cannot locate a 64-bit Oracle Client library: "Error loading shared library libnsl.so.1: No such file or directory (needed by /usr/lib/libclntsh.so)". See https://oracle.github.io/odpi/doc/installation.html#linux for help Node-oracledb installation instructions: https://oracle.github.io/node-oracledb/INSTALL.html
You must have 64-bit Oracle client libraries in LD_LIBRARY_PATH, or configured with ldconfig.
If you do not have Oracle Database on this computer, then install the Instant Client Basic or Basic Light package from http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html
So Oracle client couldn't find libnsl.so.1 even thought it should come with glibc, and I can see that it is under:
'/usr/glibc-compat/lib'.
Any ideas how to fix this? Thanks in Advance.

# 1. Install dependencies
FROM node:8.15 as cache-package
COPY package.json /srv/src/package.json
WORKDIR /srv/src
RUN yarn install
# 2.
FROM node:8.15 as builder
# 1. Update everything on the box
RUN apt-get update && \
apt-get install sudo
#RUN apk --update add libaio bc net-tools
RUN sudo apt-get install unzip
RUN sudo apt-get install wget
RUN sudo apt-get install git
# 3. Install oracle client
RUN mkdir -p /opt/oracle
# 3.1 Get oracle client
WORKDIR /opt/oracle
RUN wget -O /opt/oracle/instantclient_18_3_linux.zip http://YOUR_URL_TO_DOWNLOAD_THE_CLIENT/instantclient_18_3_linux.zip
RUN sudo unzip /opt/oracle/instantclient_18_3_linux.zip
# 3.2 Configure oracle client to work with node
RUN sudo sh -c "echo /opt/oracle/instantclient_18_3_linux > /etc/ld.so.conf.d/oracle-instantclient.conf"
RUN sudo cat /etc/ld.so.conf.d/oracle-instantclient.conf
FROM node:8.15
RUN apt-get update && \
apt-get install sudo
RUN sudo apt-get install libaio1
RUN mkdir -p /srv/src/logs
RUN mkdir -p /srv/logs
RUN mkdir -p /opt/oracle
# 4. Set the working directory
# 5. Copy our project & install our dependencies
COPY --from=cache-package /srv/src /srv/src
COPY --from=builder /opt/oracle/instantclient_18_3_linux /opt/oracle/instantclient_18_3_linux
COPY --from=builder /etc/ld.so.conf.d/oracle-instantclient.conf /etc/ld.so.conf.d/oracle-instantclient.conf
RUN sudo ldconfig
RUN ln -sf /usr/share/zoneinfo/WET /etc/localtime
COPY . /srv/src
WORKDIR /srv/src
# 6. Start the app
CMD yarn start
Here is my dockerfile working fine, the srv/src is my directory where I have my code, just change for yours and it should work.
I have the same problem as you the past two days and now it works.
