nginx is not serving go static files

问题

我的应用程序结构如下：

  1. .
  2. ├── src
  3. │   └── 一些 Go 文件
  4. ├── templates
  5. ├── static
  6.     |── images
  7.     |── js
  8.     └── styles

这是我的 Dockerfile：

  1. FROM golang:1.18
  3. WORKDIR /usr/src/app
  5. COPY go.mod .
  6. COPY go.sum .
  8. RUN go mod download
  10. COPY . .
  12. CMD ["go", "run", "src/cmd/main.go"]

这是我的 docker-compose.yml：

  1. version: "3.8"
  3. services:
  4.   pgsql:
  5.     image: postgres
  6.     ports:
  7.       - "5432:5432"
  8.     volumes:
  9.       - todo_pg_db:/var/lib/postgresql/data
  10.     environment:
  11.       - POSTGRES_DB=todo
  12.       - POSTGRES_USER=postgres
  13.       - POSTGRES_PASSWORD=postgres
  15.   app:
  16.     build: .
  17.     ports:
  18.       - "8080"
  19.     restart: always
  20.     depends_on:
  21.       - pgsql
  23.     
  24.   nginx:
  25.     image: nginx
  26.     restart: always
  27.     ports:
  28.       - 801:801
  29.     volumes:
  30.       - ./nginx.conf:/etc/nginx/nginx.conf
  33. volumes:
  34.   todo_pg_db:

这是 nginx.conf 文件：

  1. worker_processes auto;
  2. error_log /var/log/nginx/error.log;
  3. pid /var/run/nginx.pid;
  5. events {
  6.     worker_connections 1024;
  7. }
  9. http {
  10.     include mime.types;
  11.     default_type application/octet-stream;
  12.     access_log /var/log/nginx/access.log;
  13.     sendfile on;
  15.     server {
  16.         listen 801;
  17.         server_name 127.0.0.1;
  18.         charset utf-8;
  19.         keepalive_timeout 5;
  21.         location / {
  22.             # 检查静态文件，如果找不到则代理到应用程序
  23.             try_files $uri @backend;
  24.         }
  26.         location @backend {
  27.             # client_max_body_size 10m;
  28.             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  29.             proxy_set_header X-Forwarded-Proto $scheme;
  30.             proxy_set_header Host $http_host;
  31.             proxy_redirect off;
  32.             proxy_pass http://app:8080;
  33.         }
  34.     }
  35. }

我的问题是 nginx 找不到静态文件。这里是一些示例日志：

  1. open() "/usr/src/app/static/styles/bootstrap.min.css" failed (2: No such file or directory)

但是该目录确实存在。当我使用以下命令在 Docker 容器中执行时：sudo docker exec -it todo_app_1 bash，然后查看文件的内容，一切正常：

  1. cat /usr/src/app/static/styles/bootstrap.min.css
  2. # 输出：文件内容...

我不知道问题出在哪里。我漏掉了什么？

英文:

My app structure is like this:

  1. .
  2. ├── src
  3. │   └── some go files
  4. ├── templates
  5. ├── static
  6.     |── images
  7.     |── js
  8.     └── styles

And here is my Dockerfile:

  1. FROM golang:1.18
  3. WORKDIR /usr/src/app
  5. COPY go.mod .
  6. COPY go.sum .
  8. RUN go mod download
  10. COPY . .
  12. CMD ["go", "run", "src/cmd/main.go"]

And here is my docker-compose.yml:

  1. version: "3.8"
  4. services:
  5.   pgsql:
  6.     image: postgres
  7.     ports:
  8.       - "5432:5432"
  9.     volumes:
  10.       - todo_pg_db:/var/lib/postgresql/data
  11.     environment:
  12.       - POSTGRES_DB=todo
  13.       - POSTGRES_USER=postgres
  14.       - POSTGRES_PASSWORD=postgres
  16.   app:
  17.     build: .
  18.     ports:
  19.       - "8080"
  20.     restart: always
  21.     depends_on:
  22.       - pgsql
  24.     
  25.   nginx:
  26.     image: nginx
  27.     restart: always
  28.     ports:
  29.       - 801:801
  30.     volumes:
  31.       - ./nginx.conf:/etc/nginx/nginx.conf
  34. volumes:
  35.   todo_pg_db:

And here is the nginx.conf:

  1. worker_processes auto;
  2. error_log /var/log/nginx/error.log;
  3. pid /var/run/nginx.pid;
  5. events {
  6.     worker_connections 1024;
  7. }
  9. http {
  10.     include mime.types;
  11.     default_type application/octet-stream;
  12.     access_log /var/log/nginx/access.log;
  13.     sendfile on;
  15.     server {
  16.         listen 801;
  17.         server_name 127.0.0.1;
  18.         charset utf-8;
  19.         keepalive_timeout 5;
  21.         location / {
  22.             # checks for static file, if not found proxy to app
  23.             try_files $uri @backend;
  24.         }
  26.         location @backend {
  27.             # client_max_body_size 10m;
  28.             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  29.             proxy_set_header X-Forwarded-Proto $scheme;
  30.             proxy_set_header Host $http_host;
  31.             proxy_redirect off;
  32.             proxy_pass http://app:8080;
  33.         }
  34.     }
  35. }

My problem is that nginx can't find static files.
Here is some example logs:

  1. open() "/usr/src/app/static/styles/bootstrap.min.css" failed (2: No such file or directory)

But there is such directory.
when I exec to my docker container using this commad: sudo docker exec -it todo_app_1 bash.
Then I cat contents of the file, and it works fine!!!

  1. cat /usr/src/app/static/styles/bootstrap.min.css
  2. # output: file content...

I don't know what is wrong in here.
What am I missing?

得分: 2

我已经使用volumes修复了这个问题：

  1. nginx:
  2.   image: nginx
  3.   restart: always
  4.   ports:
  5.     - 801:801
  6.   volumes:
  7.     - ./static:/var/www
  8.     - ./nginx.conf:/etc/nginx/nginx.conf

在nginx.conf文件中的配置如下：

  1. location /static {
  2.     alias /var/www;
  3. }
英文:

I have fixed that using volumes:

  1. nginx:
  2.   image: nginx
  3.   restart: always
  4.   ports:
  5.     - 801:801
  6.   volumes:
  7.     - ./static:/var/www
  8.     - ./nginx.conf:/etc/nginx/nginx.conf

and in nginx.conf:

  1. location /static {
  2.     alias /var/www;
  3. }
