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nginx配置文件(与Dockerfile在同一目录中),如下所示:

Dockerfile:

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

然后我检查了所有正在运行的容器,但它没有显示出来.当我搜索nginx容器的日志时,我发现此错误消息:

[emerg] 1#1:/etc/nginx/nginx.conf中的未知指令"upstream":1/nginx:/ emerc] /etc/nginx/nginx.conf中的[upstream]未知指令"upstream":

我错过了什么？

Answer 1

如NGiNX文档中所述,upstream应该在http上下文中定义.

如nginx未知指令" upstream"中所述:

当该文件正常包含时nginx.conf,它已包含在http上下文中:

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

您需要使用-c /etc/nginx/nginx.conf或制作一个像上面的块一样的小包装器nginx -c.

对于Docker,您可以看到以下不同选项abevoelker/docker-nginx:

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

对于默认值nginx.conf,请检查您的CMD:

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

官方 nginx docker hub 手册页：

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

Answer 3

添加 gzip 配置的示例：

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

或 docker-compose：

version: '3'

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