Drone Plugins Licensing

Hello there,

I’ve been using Drone for a while now and I’m writing some plugins.

I know this is more a legal issue but I’m looking for some guidelines to understand what is the license that fits the plugins usage (given the fact that they are Docker containers that use X-Licensed binaries).

For example, I integrated Mella (Licensed under CC BY-NC-SA 4.0) into a plugin (not released to the public yet). Is this license applicable to be used with Drone?

Really sorry if I’m off-topic, I’m a little bit lost with all this. Thank you!
Andrés.
