如何使用自定义配置运行 nginx docker 容器？

Question

我有一个Dockerfile和自定义的nginx配置文件（与Dockerfile在同一个目录）如下：

Docker 文件：

FROM nginx

COPY nginx.conf /etc/nginx/nginx.conf

nginx.conf 文件:

upstream myapp1 {
          least_conn;
          server http://domain.com:81;
          server http://domain.com:82;
          server http://domain.com:83;
    }

server {
          listen 80;

          location / {
            proxy_pass http://myapp1;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
          }
    }

我运行这两个命令：

docker --tls build -t nginx-image .
docker --tls run -d -p 80:80 --name nginx nginx-image

然后我检查了所有运行ning 容器，但它没有出现。当我搜索 nginx 容器的日志时，我发现了这个错误信息：

[emerg] 1#1: unknown directive "upstream" in /etc/nginx/nginx.conf:1 nginx: [emerg] unknown directive "upstream" in /etc/nginx/nginx.conf:

我错过了什么？

Answer 1

如 NGiNX documentation 中所述，upstream 应该在 http 上下文中定义。

如nginx unkown directive “upstream”所述：

When that file is included normally by nginx.conf, it is included already inside the http context:

http {
  include /etc/nginx/sites-enabled/*;
}

You either need to use -c /etc/nginx/nginx.conf or make a small wrapper like the above block and nginx -c it.

在 Docker 的情况下，您可以看到 abevoelker/docker-nginx 的不同选项：

docker run -v /tmp/foo:/foo abevoelker/nginx nginx -c /foo/nginx.conf

对于默认值 nginx.conf，check your CMD：

CMD ["nginx", "-c", "/data/conf/nginx.conf"]

Answer 2

添加gzip配置的示例：

docker run -v [./]gzip.conf:/etc/nginx/conf.d/gzip.conf nginx

或docker-撰写：

version: '3'

services:
  nginx:
    image: nginx
    volumes:
      - ./gzip.conf:/etc/nginx/conf.d/gzip.conf
      - ./html:/usr/share/nginx/html:ro

nginx 官方 docker hub 手册页：

docker run --name my-custom-nginx-container -v /host/path/nginx.conf:/etc/nginx/nginx.conf:ro -d nginx
