Fail2ban for Docker

方式一：在主要服務的 container 裡安裝 Fail2ban

NOTE：

The container must be launched with the NET_ADMIN capability in order to be able to install the iptable rules that actually ban IP addresses. Thus either include --cap-add=NET_ADMIN in the docker run commandline or the equivalent docker-compose.yml:

docker-compose.yml：

cap_add:
     - NET_ADMIN
