Zenoh in Docker does not load plugins from /root/.zenoh/lib

[philrhc]

Describe the bug

Zenoh router does not load plugins from /root/.zenoh/lib

• Followed the steps here: https://zenoh.io/docs/getting-started/quick-test/#adding-plugins-and-backends-to-the-container
• Attached shell shows the .so files in /root/.zenoh/lib
• See the log line 2024-05-15T14:30:14.863318Z DEBUG main ThreadId(01) zenoh_util::std_only::lib_loader: Search for library libzenoh_plugin_rest.so to load in ["/", "/root/.zenoh/lib", "/usr/local/lib", "/usr/lib", "/"]
• See the below response:

curl 'http://localhost:8000/@/router/local'
[
{ "key": "@/router/79887a32dad6ef34f82f4ed312390b69", "value": {"locators":["tcp/172.29.0.2:7447"],"metadata":null,"plugins":{"rest":{"path":"/libzenoh_plugin_rest.so"}},"sessions":[],"version":"v0.11.0-rc.3 built with rustc 1.72.0 (5680fa18f 2023-08-23)","zid":"79887a32dad6ef34f82f4ed312390b69"}, "encoding": "application/json", "time": "None" }
]

To reproduce

Created a minimum repo w/ the docker compose but should be fairly easy to test w/ a docker compose file

got one step further:
it looks like zenoh does not load plugins by default from /root/.zenoh/lib as mentioned here:

https://zenoh.io/docs/getting-started/quick-test/

By default the Zenoh router will search for plugins and backends libraries to load in ~/.zenoh/lib. Thus, to make it able to find the libraries, you can copy them into a zenoh-docker/lib directory on your local host and mount the zenoh-docker directory as a volume in your container targeting /root/.zenoh.

ideally i can pass the configuration file to zenohd somehow...

ok, closing because i don't think this is a bug, i think it is a fault in the documentation. I'll continue investigating...
