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

Fri Feb 10 19:05:17 UTC 2017

Hello,

Just a clarification: these steps should be needed only if your tool is
using binary modules. There are edge cases where the compilation might
fail, so please try it locally first with the version v6.9.1 of Node.

Cheers,
Marko
