Just a note - you can very much limit cpu usage on the docker containers by setting --cpus="0.5" (or cpus:0.5 in docker compose) if you expect it to be a very lightweight container, this isolation can help prevent one roudy container from hitting the rest of the system regardless of whether it's crypto-mining malware, a ddos attempt or a misbehaving service/software.
