Docker Nginx ngx_http_image_filter_module

请帮我配置Nginx和Docker的ngx_http_image_filter_module模块.

我想用Nginx创建图像缩略图.我知道这需要ngx_http_image_filter_module.如果我看一下DockerfileDockerfile,我可以看到它已经用nginx-module-image-filter构建(我相信这是我需要的).但是当我尝试在Nginx配置中使用image_filter resize 100 100时,Docker无法启动此容器并抛出错误:

nginx_1 | 2016/11/13 13:28:28 [emerg] 1#1: unknown directive “image_filter” in /etc/nginx/conf.d/nginx.conf:34

nginx_1 | nginx: [emerg] unknown directive “image_filter” in /etc/nginx/conf.d/nginx.conf:34

我已经尝试使用自己的Dockerfile构建容器,但没有任何改变.我用过这个Dockerfile:

FROM nginx

RUN apt-get update

RUN apt-get install --no-install-recommends --no-install-suggests -y \
                        nginx-module-image-filter

我的主机配置(位于/etc/nginx/conf.d/下)

server {
  listen 80;

  location /images/originals/ {
    alias /site/storage/app/public/images/originals/;
    image_filter resize 100 100;
  }
}

更新

Nginx配置(标准)

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

顺便说一句,如果我打入nginx容器并运行nginx -V我得到以下内容:

root@8abdbeab3e2e:/etc/nginx/conf.d# nginx -V

我们可以看到这里没有图像过滤器模块.

更新3

我已经清理了所有内容,删除了所有图像和容器,并从头开始.

我将这个docker-compose文件用于我的nginx容器:

nginx:
    image: nginx
    build:
      context: ./env/nginx
    ports:
      - '80:80'
    volumes:
      - ./env/nginx/abmotors.conf:/etc/nginx/conf.d/abmotors.conf:ro

这是位于./env/nginx的Dockerfile(用于构建nginx容器)

FROM nginx

RUN apt-get update

RUN apt-get install --no-install-recommends --no-install-suggests -y \
                        libgd-dev \
                        nginx-module-image-filter

一切都在积累,但当我运行并打入nginx容器并运行nginx -V时,它给了我以下内容:

root@7087db72bdb1:/# nginx -V

仍然没有关于libgd和image-filter模块的信息.

提前致谢.

解决方法:

Nginx在1.9.11中引入了动态模块,“image-filter”现在只是动态模块之一.

Nginx标准的Docker镜像已经提供了它:

$docker run -it --rm nginx:mainline ls -l /etc/nginx/modules/ | grep image
-rw-r--r-- 1 root root  23536 Oct 11 15:54 ngx_http_image_filter_module-debug.so
-rw-r--r-- 1 root root  23536 Oct 11 15:54 ngx_http_image_filter_module.so

但是模块没有被默认的Nginx根配置文件/etc/nginx/nginx.conf加载,因为它被认为是“可选的”.您需要做的是将以下行放入该文件中:

load_module /etc/nginx/modules/ngx_http_image_filter_module.so;

在顶层!这就是定义守护进程,用户,http的地方.
