Why is container deprecated

[DaanBiesterbos]

Hi :-)

Thanks for this useful library.

I would like to ask why the container parameter is deprecated? It seems to make more sense to use "container" especially when using docker-compose. I don't see how adding json to an environment variable improves anything while the container property is straight forward, easy to use and works like a charm. The same can't be said about the filters property. When I try to use the value from the examples I get "Invalid interpolation format" errors. There should be a solution for it but still..... Container does give a headache. I am a big fan of "container".

Kind regards,
Daan
