I've seen several questions regarding macOS, Docker and bcrypt on Node.js. This seems the closest answer to my problem but it didn't work.
My Dockerfile:
FROM node:6.4.0
COPY . /app
RUN ls -la /app
WORKDIR /app
RUN cd /app; npm install
CMD ["node", "index.js"]
My .dockerignore file:
node_modules
My package.json dependencies:
"dependencies": {
"bcrypt": "1.0.0",
}
When starting the container, I get this error:
/app/node_modules/bcrypt/build/Release/bcrypt_lib.node: invalid ELF header
From the ls -la /app command in the Dockerfile I can see that the node_modules folder definitely isn't copied from the host (macOS):
drwxr-xr-x 6 root root 4096 Dec 7 21:29 .
drwxr-xr-x 47 root root 4096 Dec 7 21:29 ..
-rw-r--r-- 1 root root 763 Dec 7 20:55 .dockerignore
-rw-r--r-- 1 root root 122 Dec 7 21:18 Dockerfile
rw-r--r-- 1 root root 13525 Dec 7 19:43 index.js
-rw-r--r-- 1 root root 947 Dec 7 21:28 package.json
The bcrypt npm install log:

Update:
I tried to run bcrypt inside the container which seems to work fine:
docker run identity file /app/node_modules/bcrypt/build/Release/bcrypt_lib.node
/app/node_modules/bcrypt/build/Release/bcrypt_lib.node: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=2a9d4a04f6f9c548f8035b9b737c1efac5d774d2, not stripped
I have found that excluding the entire local node_modules directory does not allow you to install npm packages and have your docker container track those changes in the container on the fly. In order to have other package changes tracked specify only the bcrypt directory in the container volume:
volumes:
- .:/app
- /app/node_modules/bcrypt/
