失败 2 禁止未发现 IP

当从另一台服务器测试我的应用程序时fail2ban，我看到以下日志：

2021-08-01 18:48:37,692 fail2ban.filter         [1]: INFO    [nginx] Found 51.195.221.70 - 2021-08-01 18:48:37

即使被发现并被禁止，请求仍可继续。我的 Docker 容器如下所示：

 fail2ban:
    image: 'crazymax/fail2ban:latest'
    restart: 'always'
    network_mode: 'host'
    cap_add:
      - 'NET_ADMIN'
      - 'NET_RAW'
    volumes:
      - 'nginx-log:/var/log:ro'
      - 'fail2ban-data:/data'
    env_file:
      - './fail2ban.env'

我的配置是：

jail.d/nginx.conf

[nginx]
enabled = true
logpath = /var/log/access.log
port = http,https

过滤器.d/nginx.conf

[Definition]
failregex = ^<HOST> \- \S+ \[\] \"(GET|POST|HEAD) .+\" 419 .+$
ignoreregex =

任何帮助都值得感激。我需要配置 IP 表吗？

我发现我需要添加chain = DOCKER-USER一些内容jail.d/nginx.conf才能使其工作。
