要使用set-misc-nginx模块，我需要在NGINX官方Docker映像中进行哪些更改? [英] What do I need to change in NGINX official Docker's image to have the set-misc-nginx module?

问题描述

我需要使用此库中的随机数生成器 ，但我想使用官方nginx图像 ，所以我试图查看其源代码并执行安装此库所需的更改.

I need to use the random number generator from this library, but I wanted to use the official nginx image, so I was trying to see its source code and perform the changes required to have this library installed.

但是我很茫然，因为这些指令似乎与在该Dockerfile中安装NGINX的方式不匹配.

But I am at loss, as the instructions don't seem to fit with the way NGINX is being installed in that Dockerfile.

如何在官方NGINX Dockerfile中安装set-misc-nginx?

How can I install set-misc-nginx within the official NGINX Dockerfile?

推荐答案

您可以扩展官方ngnix 构建动态模块，然后将其加载到nginx:

You can extend the official ngnix to build the dynamic modules then load them in nginx:

# syntax=docker/dockerfile:experimental
ARG NGINX_VERSION
FROM nginx:${NGINX_VERSION} as build

RUN apt-get update && \
    apt-get install -y \
        openssh-client \
        git \
        wget \
        libxml2 \
        libxslt1-dev \
        libpcre3 \
        libpcre3-dev \
        zlib1g \
        zlib1g-dev \
        openssl \
        libssl-dev \
        libtool \
        automake \
        gcc \
        g++ \
        make && \
    rm -rf /var/cache/apt

RUN wget "http://nginx.org/download/nginx-${NGINX_VERSION}.tar.gz" && \
    tar -C /usr/src -xzvf nginx-${NGINX_VERSION}.tar.gz

RUN mkdir -p -m 0600 ~/.ssh && \
    ssh-keyscan github.com >> ~/.ssh/known_hosts

WORKDIR /src/ngx_devel_kit
RUN --mount=type=ssh git clone [e-mail]:simpl/ngx_devel_kit .

WORKDIR /src/set-misc-nginx-module
RUN --mount=type=ssh git clone [e-mail]:openresty/set-misc-nginx-module.git .

WORKDIR /usr/src/nginx-${NGINX_VERSION}
RUN NGINX_ARGS=$(nginx -V 2>&1 | sed -n -e 's/^.*arguments: //p') \
    ./configure --with-compat --with-http_ssl_module --add-dynamic-module=/src/ngx_devel_kit --add-dynamic-module=/src/set-misc-nginx-module ${NGINX_ARGS} && \
    make modules

FROM nginx:${NGINX_VERSION}

COPY nginx.conf /etc/nginx/nginx.conf
COPY --from=build /usr/src/nginx-1.17.3/objs/ngx_http_set_misc_module.so /usr/src/nginx-1.17.3/objs/ndk_http_module.so /usr/lib/nginx/modules/

注意:此示例为 multi使用docker 构建增强功能的分阶段构建克隆存储库(取决于您的docker版本，您可能必须启用实验功能).

Note: this example is a multi-staged build that uses the docker build enhancements to clone the repositories (depending on your version of docker you may have to enable experimental features).

您可以将模块加载到最终图像中复制的nginx.conf中:

You can load the modules in the nginx.conf that's copied in the final image:

user  nginx;
worker_processes  1;

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

load_module /usr/lib/nginx/modules/ndk_http_module.so;
load_module /usr/lib/nginx/modules/ngx_http_set_misc_module.so;

events {
    worker_connections  1024;
}

http {
    ...
}

构建图像:DOCKER_BUILDKIT=1 docker build --rm --ssh=default --build-arg NGINX_VERSION=1.17.3 --network host -t so:57739560 .

运行容器:docker run --rm -it -p 80:80 so:57739560

对于使用官方nginx图像构建动态模块的另一个示例，您可以查看我的 nginx- modsecurity repo(nginx图片扩展了 Modsecurity 和 Modsecurity-nginx ).

For another example of building dynamic modules using the official nginx image you can check out my nginx-modsecurity repo (nginx image extended with Modsecurity and Modsecurity-nginx).
