Getting a 'conflicting engine id' error in JWT module

[xo-chris]

Hi there

I call the 'authorize' function of the JWT module and get error Error: error:26078067:engine routines:ENGINE_LIST_ADD:conflicting engine id

Full details
I am using a windows 7.1 machine but I am running this under docker, using the iron.io docker image. So in the docker BASH shell I execute command:

$ docker run --rm  -v "//$PWD":/worker -w //worker iron/node:4.1 node index.js

and receive stack trace

Error: error:26078067:engine routines:ENGINE_LIST_ADD:conflicting engine id

    at JWT.refreshToken_ (/worker/node_modules/google-auth-library/lib/auth/jwtC
lient.js:133:15)

My code:

var jwt = require('google-auth-library/lib/auth/jwtClient');
var key = require('mykeyfile.json');
var jwtClient = new jwt(key.client_email, null, key.private_key, ['https://www.google.com/m8/feeds']); 

jwtClient.authorize(function(err, tokens) {
     if (err) {throw err;}

 console.log ("authorised :-)");
 console.log("token " + tokens.access_token);


 })

Any help much appreciated

BTW the issue is in the container itself: gliderlabs/docker-alpine#127 just downgraded to 0.12 on alpine and works well -- they have a fix in the upstream though: http://git.alpinelinux.org/cgit/aports/commit/?id=30beca0f2f1de59e9fc8632d2807da50057217aa

The Iron docker images appear to be unmaintained:
https://hub.docker.com/r/iron/node/

I'd really suggest sticking to the official node.js docker alpine distribution:
https://hub.docker.com/_/node/

Just to make sure there were no lingering issues, I threw together a sample using our upcoming release, that runs on node.js 8.9 on alpine, using the official images:
https://github.com/JustinBeckwith/alpine-node-jwt-sample

Given the age of the issue, and the fact that I can't seem to create a meaningful repo - I am going to go ahead and close this out. If this is still an issue, and you can provide repo steps - I'd be happy to open it back up and take a look. Thanks!
