alpine-node docker image and google-cloud equals error loading ld-linux-x86-64.so.2

• OS:
  Linux 4.4.20-moby (a docker image from mhart/alpine-node:6.9.1
• Node.js version:
  6.9.1 (and back to at least 6.7.0)
• npm version:
  3.10.8
• google-cloud-node version:
  0.43.0

I started using the google-cloud sdk a few weeks ago and was using the mhart/alpine-node image for its "slenderness". When I introduced google-cloud into my code I went to build my docker file using alpine-node to discover the following error:

module.js:597
return process.dlopen(module, path._makeLong(filename));
^

I switched to using the normal node docker image based on debian and of course I don't get the error and everything works well.

However, I would like to switch back to alpine-node to get rid of all the weight...

How can I fix this error?

Thanks

The line that's failing, process.dlopen, is the mechanism that Node uses to load native extensions. It looks like your system doesn't support that, and without it, gRPC on Node simply will not work.

I did some more investigating...and googling....and got it working. Sorry to have polluted your board. But for posterity...

I found this: http://blog.kontena.io/docker-for-mac-glibc-issues/ which pointed out that Alpine Linux uses musl libraries and by default doesn't have the glibc libraries installed or something like that....so I found a package in the Alpine Linux repository, lib6compat, and installed it when building my docker image based on mhart/alpine-node:6.9.1 and it solved the problem. My node app now works just like with the debian based node image.

Unfortunately, I am also experiencing this issue with a recent version of Alpine leveraged by official Node.js image: node:8.7.0-alpine. So I don't believe the fix is either live or resolving. Here is the stack I see when building my Docker image:

`[nodemon] starting node dist/server.js
module.js:653
return process.dlopen(module, path._makeLong(filename));
^

Any recommendations to move forward?

@chrisalexander55 Did you find any solution?

[chrisalexander55]

I used the repeated keyword on a type containing members string key; string value;

@chrisalexander55 mind elaborating?

[nicolas-chaulet]

Same issue here with alpine-node:8, any idea?

[murgatroid99]

Can you elaborate? What version of gRPC are you using? Are you seeing the same dlopen error?
