"variables_hash_max_size" directive is duplicate

[xavierdemoor]

Describe the bug When I docker-compose up, I have this error before nginx exiting:

2019/07/04 12:02:38 [emerg] 1#1: "variables_hash_max_size" directive is duplicate in /etc/nginx/conf.d/botblocker-nginx-settings.conf:18

To Reproduce Steps to reproduce the behavior:

1. I just picked the docker-compose php example (and changing paths)

Expected behavior

Additional context I'm using Docker for Windows

Can you paste your compose file? Also, what is in the path you are mounting? For example, what base configs are you using?

[xavierdemoor]

docker-compose.yml

version: '3.1'
services:
  nginx:
    image: openbridge/nginx
    container_name: nginx
    depends_on:
      - redis
    ports:

I took the conf and env files from this repo. I didn't change anything in those files. In my /web folder, I only have a index.php with phpinfo();

the botblocker-nginx-settings.conf file is present in the container but not in the conf/ folder.

Ok, I released a fix. Not sure why this started to occur, but it looks like something on the botblocker side. Since botblocker us a runtime config, a change upstream can cause a problem like this. For now I commented out the botblocker config.

[tspicer]

I just ran the installer for https://wordpress.chatlytics.co/ and everything worked without error.

Thank you !

I'm still getting the same problem (same config than above) I have tried with several different tags. What version is supposed to have the fix?

[tspicer]

Hi, can you try setting an ENV variable: https://github.com/openbridge/nginx#activating-bot-protection

Please share your ENV settings as well.

[goat-io]

Hi, I tried with both the bot enabled and disabled. Same results

ENV

NGINX_SERVER_NAME=127.0.0.1
NGINX_CONFIG=php
NGINX_DEV_INSTALL=false
PHP_FPM_UPSTREAM=wordpress:9000
REDIS_UPSTREAM=redis:6379
NGINX_PROXY_UPSTREAM=localhost:8080
NGINX_DOCROOT=/usr/share/nginx/html
NGINX_BAD_BOTS=true

Compose

nginx_prod:
    build:
      context: .
      dockerfile: ./docker/nginx/Dockerfile
    depends_on:
      - redis
    ports:
      - 80:80
      - 443:443
    tty: true
    ulimits:
      nproc: 65535
      nofile:

        hard: 99999
    restart: unless-stopped
    networks:
      - wordpress-network
    env_file:
      - ./.env

Dockerfile (Just some custom config for woocommerce cache and cdn)

FROM openbridge/nginx:latest
COPY --chown=www-data:www-data ./docker/nginx/cdn.conf  /conf/php/nginx/conf.d/cdn.conf
COPY --chown=www-data:www-data ./docker/nginx/nocache.map  /conf/php/nginx/map.d/nocache/nocache.map

Can you also share some of the log outputs docker logs nginx or whatever you have it named?

Here is the last portion of the logs

Hi @tspicer,

I had to stop all the services, do a complete system prune

system prune -a

to remove everything from my local system and only after this full prune a got it back working. Seems that somehow was a local image/volume problem. Very likely that is safe to close this issue. Thanks for your help
