Question

linux

Is it possible to somehow use Fail2Ban from under docker for the main OS?
I don't want to constantly adjust from 0.

Answer 1

I don't want to constantly adjust from 0.

Write an Ansible playbook or Bash script.

Answer 2

Try running with network=host

Answer 3

Well, as if it is quite possible. You need --net=host in order for fail2ban to edit iptables on the host, you need to upload (or drive into the image) the config, you need to upload the logs it studies, and don't forget about privileged mode. But why? He, in fact, only needs to configure the config once and use it everywhere, ansible was already advised above to simplify this operation.
