[Labs-l] [tools] [kubernetes] [node] NodeJS webservices on Kubernetes may need npm packages to be rebuilt

[Bryan Davis]

Magnus ran into a problem with one of his tools [0] that may affect
others as well.

The version of Node used for WMF's production services running on
Debian Jessie has been upgraded to v6.9.1 recently [1].  We also
rebuilt the Docker base images that are used to run tools on
Kubernetes on 2017-02-08 and subsequently restarted all of the
Kubernetes tools to pick up the new containers and switch to a newer
version of the Docker runtime [2].

This Node version update may be incompatible with some npm installed
packages built with the previous version of node. The fix for Magnus'
tool was:

  $ webservice stop
  $ webservice --backend=kubernetes nodejs shell
  $ cd www/js
  $ mv node_modules node_modules-old
  $ npm install
  $ exit
  $ webservice --backend=kubernetes nodejs start
