Node-oracledb invalid ELF header on linux

问题

I'm using a dockerized setup of node-oracledb (based on docker-node-oracle) together with Node 10 but this error keeps popping up when I start the container:

backend_1  | /app/node_modules/oracledb/lib/oracledb.js:68
backend_1  |       throw new Error(nodbUtil.getErrorMessage('NJS-045', nodeInfo));
backend_1  |       ^

I've tried it with different node versions (8 and 9) but the same error keeps popping up which indicates that there might be a problem with the setup of my image but I can't figure out what. Here's the dockerfile:

# INSTALL UBUNTU
FROM node:10

#INSTALL LIBAIO1 & UNZIP (NEEDED FOR STRONG-ORACLE)
RUN apt-get update \
    && apt-get install -y libaio1 \
    && apt-get install -y build-essential \
    && apt-get install -y unzip \
    && apt-get install -y curl

#ADD ORACLE INSTANT CLIENT
RUN mkdir -p opt/oracle
ADD ./oracle/linux/ .

# 12.2
RUN unzip instantclient-basic-linux.x64-12.2.0.1.0 -d /opt/oracle \
    && mv /opt/oracle/instantclient_12_2 /opt/oracle/instantclient

RUN cd /opt/oracle/instantclient \
    && ln -s libclntsh.so.12.1 libclntsh.so \
    && ln -s libocci.so.12.1 libocci.so 

RUN echo /opt/oracle/instantclient > /etc/ld.so.conf.d/oracle-instantclient.conf

ENV LD_LIBRARY_PATH="/opt/oracle/instantclient"

WORKDIR app

ARG NODE_ENV
ENV NODE_ENV $NODE_ENV

COPY package.json .

RUN npm install

COPY . .
RUN ./build.sh

CMD [ "./up.sh" ]

Anyone who knows/had this problem with node-oracledb?

回答1:

After help from Christopher at the above mentioned post I got it working. Together with his Dockerfile and a clean slate (deleting all Docker images/containers, restarting pc,...) I got it working. Thx for the help!

回答2:

You need to add node_modules to .dockerignore then remove it node_modules
