Docker based deployment question: "--link" feature to be deprecated?

Graylog Central (peer support)

I’m trying to create a docker based Graylog-community deployment for production use. I’m trying to keep it simple so far: two servers - one running the Graylog + Mongo containers and the other running the ES container.

When reviewing the Graylog Docker instructions (http://docs.graylog.org/en/3.0/pages/installation/docker.html), there is usage of a Docker feature/function called “–link” in the sample to enable internal communications between the solution containers (Mongo, ES and Graylog). It appears thought that the “–link” feature/function is going to be deprecated at some point (https://docs.docker.com/network/links/) with the direction now being docker user-defined networks.

Has anyone performed a Docker based deployment of Graylog using user-defined networks instead of --links? If so, are there any examples that can be uploaded for reference?

Thanks,

T.

Yes the feature is deprecated … You are welcomed to update the documentation as this is open source too.

I had create a lab myself but did not have the time yet to make this into the documentation:
