Using @google-cloud/datastore in Docker project creates cannot find error for grpc

[DaveyEdwards]

Environment details

• OS: Windows 10
• Node.js version: 6.11.2
• npm version: 3.10.10
• google-cloud-node version: 1.1.0

Steps to reproduce

Note I am not using grpc in the project

1. install @ google-cloud/datastore in Docker app
   I am trying this on base version of: https://github.com/kriasoft/nodejs-api-starter
2. start server
3. Get the following error

api_1    | Error: Cannot find module '/usr/src/app/node_modules/@google-cloud/datastore/node_modules/grpc/src/node/extension_binary/node-v57-linux-x64/grpc_node.node'

api_1    | module.js:529
api_1    |     throw err;
api_1    |     ^

If I try and install this into the project with yarn I get an error and can't even install it

Trying to install google-cloud does the same

I have this working fine with another application that isn't using Docker which is leading me to believe something with Docker is likely the issue.

Possible duplicate of
#1820
and it was moved to
grpc/grpc#8860

Although I was not able to get it working with any of the solutions in the thread

[stephenplusplus]

This issue was moved to grpc/grpc#12780

[stephenplusplus]

Thanks for reporting. I've moved the issue to the gRPC repository, as they're likely the right ones to find an answer. Sorry for the trouble.

@DaveyEdwards you can try to solve it by adding libc6-compat to Dockerfile and Dockerfile.dev. Then run:

$ rm -rf ./node_modules
$ docker-compose build --no-cache
$ docker-compose run --rm --no-deps api yarn
$ docker-compose up

[DaveyEdwards]

@koistya This worked perfectly thanks!

my dockerfile now looks like:

FROM node:8.6.0-alpine

# Set a working directory
WORKDIR /usr/src/app

# Copy application files
COPY . .

# Install dependencies
RUN apk add --no-cache libsodium libc6-compat && \
  yarn install --production --no-progress && \
  yarn cache clean

# Run the container under "node" user by default
USER node

CMD [ "node", "build/server.js" ]

and the Dockerfile.dev

FROM node:8.6.0-alpine

# Set a working directory
WORKDIR /usr/src/app

# If you have native dependencies, you'll need extra tools
RUN apk add --no-cache make g++ python2 libsodium-dev libc6-compat && \
  npm install -g node-gyp && \
  mkdir -p /home/node/.cache/yarn && \
  chown -R node:node /home/node/.cache/yarn && \
  chmod 777 /home/node/.cache/yarn

VOLUME /home/node/.cache/yarn

# Run the container under "node" user by default
USER node
