I had it in docker first, but because I just have the smallest server on Digital Ocean with 500 MB RAM and already running redis and Postgres, using Docker made it obviously start complete new instances which would fill the RAM and swap and make the load go up to 20. After reusing the already running services and removing docker I could easily fit everything in the existing RAM+swap and the load would go down to 0.15, that is why I decided not to use docker, even if it is much nicer for deployment. The smallest offering at Digital Ocean is $5/month, if I want to go up with RAM it's additional $5 per GB of RAM, to get it running nicely in docker it seems I'd need to pay 3 times the monthly fee of what I'm paying now.
