用于NGINX Web服务器的Dockerfile

我一直在试图build立一个托pipeNGINX服务器的本地Docker容器。 首先，这里是我的Dockerfile：

# Set nginx base image FROM nginx # File Author / Maintainer MAINTAINER myuser "[e-mail]" # Copy custom configuration file from the current directory COPY nginx.conf /etc/nginx/nginx.conf 

我使用docker build命令构build了这个文件，当我列出这些图像时，我可以在列表中看到这个图像。

现在，我试图运行这个新创build的图像，导致一个错误：

 my-MacBook-Pro:nginx-docker me$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE myrepo nginx-latest 0d73419e8da9 12 minutes ago 182.8 MB hello-world latest c54a2cc56cbb 13 days ago 1.848 kB nginx latest 0d409d33b27e 6 weeks ago 182.8 MB my-MacBook-Pro:nginx-docker me$ docker run -it myrepo:nginx-latest 2016/07/15 07:07:35 [emerg] 1#1: open() "/etc/nginx/logs/access.log" failed (2: No such file or directory) nginx: [emerg] open() "/etc/nginx/logs/access.log" failed (2: No such file or directory) 

日志文件的path是在我的nginx.conf中configuration的，如下所示：

 #user nobody; worker_processes 1; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { include 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 logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; server { listen 8080; server_name localhost; root /Users/me/Projects/Sandbox/my-app; #charset koi8-r; access_log logs/host.access.log main; # # Wide-open CORS config for nginx # location / { add_header 'Access-Control-Allow-Origin' '*'; add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS'; add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type'; } # /api will server your proxied API that is running on same machine different port # or another machine. So you can protect your API endpoint not get hit by public directly location /api { proxy_pass http://localhost:9000; 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; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; add_header Access-Control-Allow-Origin *; proxy_set_header Access-Control-Allow-Origin $http_origin; } error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { # deny all; #} } include servers/*; } 

当我现在试图运行这个NGINX图像时，出现以下错误：

 2016/07/15 07:07:35 [emerg] 1#1: open() "/etc/nginx/logs/access.log" failed (2: No such file or directory) nginx: [emerg] open() "/etc/nginx/logs/access.log" failed (2: No such file or directory) 

我该怎么办才能解决这个问题？ 还有什么和那个path应该在哪里？ 我想它是在Docker公开的底层操作系统path上？

Dockerfile的基础镜像是nginx （ nginx:latest Dockerfile是nginx:latest ）。 它有一个来自Debian Nginx包的预configuration的nginxconfiguration。 您可以自己检查容器： docker run -it --rm nginx /bin/bash并查看文件和目录以了解有关它的一些事实：

• 它提供了nginx用户
• 它提供/var/log/nginx目录，但是root拥有它
• 它在任何人都可以写的目录中提供access.log和error.log

（基本的Nginx镜像的Dockerfile在这里 ）

您的configuration：

• 作为nginx运行Nginx（这是默认的 ）
• 尝试将日志文件写入/etc/nginx/logs

显然，这个目录不存在，因为没有人创build它。 如果存在，应该由nginx用户写入。
