How should the Ignite node autodiscovery on Google Cloud be enabled - ignite

Question

I deployed my instance using the steps on https://apacheignite.readme.io/docs/google-compute-deployment
and made some configuration changes to enable cloud storage based discovery.
I think I have to specify an optional lib to get the cloud storage discovery module on the classpath, but specifying the OPTION_LIBS variable so that it includes 'ignite-gce' does not have any effect in my case. The logs of the docker container say this:

Note! You may use 'USER_LIBS' environment variable to specify your classpath.
```
What should I do in order to make the docker container pick up this OPTION_LIBS variable?

Answer 1

It's actually OPTION_LIBS, not OPTIONAL_LIBS.
