Access Fail2Ban Data from Docker Container

[Shaun-Harrison]

Hello

Been using a modified version of this script for quite some time, finally decided to look at the container as always been running as a service so that I could run bash commands within the script to get some data

Is it possible to be able to get data from the host when using the container? Basically want to know if there are any IPS in the fail2ban jail, which I previously done with (not an software engineer so take my code with a grain of salt :D) ;

def get_fail2ban_sshd_banned():
    print("DEBUG: F2B SSH")
    proc1 = subprocess.run(['fail2ban-client status sshd'], stdout=subprocess.PIPE, shell=True)
    proc2 = subprocess.run(['sed -n 7p'], input=proc1.stdout, stdout=subprocess.PIPE, shell=True)
    proc3 = subprocess.run(['tr -dc "0-9"'], input=proc2.stdout, stdout=subprocess.PIPE, shell=True)
    answer = os.linesep.join([s for s in proc3.stdout.decode().splitlines() if s])
    answer = answer.strip()
    answer = str(answer)
    return answer
