在瀏覽器中服務 Laravel 的 Docker 容器

  • January 24, 2021

我正在嘗試為 laravel 應用程序啟動一個 docker 容器：-

編輯

Dockerfile.nginx

FROM nginx:alpine

COPY ./nginx/my-site-config.conf /etc/nginx/conf.d/default.conf

nginx/my-site-config.conf

server {
listen       8027;
server_name  localhost;

# handle .php
location ~ \.php$ {
   # 404
   try_files                     $fastcgi_script_name =404;

   # default fastcgi_params
   include                       fastcgi_params;

   # fastcgi settings
   fastcgi_pass                  php-fpm-container:9000;
   fastcgi_index                 index.php;
   fastcgi_buffers               8 16k;
   fastcgi_buffer_size           32k;

   # fastcgi params
   fastcgi_param DOCUMENT_ROOT   $realpath_root;
   fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
   fastcgi_param PHP_ADMIN_VALUE "open_basedir=$base/:/usr/lib/php/:/tmp/";
}
}

碼頭工人-compose.yml

#Nginx Service <-- doesn't work
#  webserver:
#    build:
#      context: .
#      dockerfile: Dockerfile.nginx
#    container_name: webserver
#    restart: unless-stopped
#    tty: true
#    ports:
#      - "8027:80"
#      - "443:443"
#    networks:
#      - app-network

# works
webserver:
image: nginx:alpine
container_name: webserver
restart: unless-stopped
tty: true
ports:
 - "8027:80"
 - "443:443"
networks:
 - app-network

註釋掉的程式碼無法啟動：-

在此處輸入圖像描述

使用未註釋的程式碼並nginx:alpine作為圖像 - 伺服器託管 nginx 啟動螢幕。我的Dockerfile.nginx出現了問題。

檢查你nginx:alpine的 nginx 配置

docker run -it --rm nginx:alpine /bin/sh
/ # cd /etc/nginx
/etc/nginx # ls -l
total 44
drwxr-xr-x    2 root     root            24 Dec 17 15:01 conf.d
-rw-r--r--    1 root     root          1077 Dec 15 14:55 fastcgi.conf
-rw-r--r--    1 root     root          1007 Dec 15 14:55 fastcgi_params
-rw-r--r--    1 root     root          2837 Dec 15 14:55 koi-utf
-rw-r--r--    1 root     root          2223 Dec 15 14:55 koi-win
-rw-r--r--    1 root     root          5231 Dec 15 14:55 mime.types
lrwxrwxrwx    1 root     root            22 Dec 17 15:01 modules -> /usr/lib/nginx/modules
-rw-r--r--    1 root     root           646 Dec 15 14:55 nginx.conf
-rw-r--r--    1 root     root           636 Dec 15 14:55 scgi_params
-rw-r--r--    1 root     root           664 Dec 15 14:55 uwsgi_params
-rw-r--r--    1 root     root          3610 Dec 15 14:55 win-utf

這是預設的 nginx.conf

/etc/nginx # cat nginx.conf 

user  nginx;
worker_processes  auto;

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


events {
   worker_connections  1024;
}


http {
   include       /etc/nginx/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  /var/log/nginx/access.log  main;

   sendfile        on;
   #tcp_nopush     on;

   keepalive_timeout  65;

   #gzip  on;

   include /etc/nginx/conf.d/*.conf;
}

在文件夾裡面conf.d，有一個預設的伺服器配置

/etc/nginx # ls -l conf.d/
total 4
-rw-r--r--    1 root     root          1093 Dec 15 14:55 default.conf

其中有一個非常基本的伺服器部分

/etc/nginx # grep -vE " *#|^ *$" conf.d/default.conf 
server {
   listen       80;
   server_name  localhost;
   location / {
       root   /usr/share/nginx/html;
       index  index.html index.htm;
   }
   error_page   500 502 503 504  /50x.html;
   location = /50x.html {
       root   /usr/share/nginx/html;
   }
}

如您所見，它僅配置為伺服器靜態內容，並且沒有將請求轉發到*.php支持的 php-fpm 的部分。

通常你需要替換這個文件（或者如果你需要更多的控制，nginx.conf一起覆蓋）。

至少您需要在伺服器配置中使用一個部分來將請求重定向到 PHP 到後端。

   # handle .php
   location ~ \.php$ {
# 404
try_files                     $fastcgi_script_name =404;

# default fastcgi_params
include                       fastcgi_params;

# fastcgi settings
fastcgi_pass                  php-fpm-container:9000; # <--- this is the PHP-FPM container
fastcgi_index                 index.php;
fastcgi_buffers               8 16k;
fastcgi_buffer_size           32k;

# fastcgi params
fastcgi_param DOCUMENT_ROOT   $realpath_root;
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param PHP_ADMIN_VALUE "open_basedir=$base/:/usr/lib/php/:/tmp/";
   }

你可以使用DO 的 NGINX 配置工具來幫助你為你的應用程序創建一個好的起點，然後你可以在nginx:apline容器中覆蓋它。

請注意，nginx 容器和 php 容器都需要訪問您的 PHP 應用程序文件。

自定義 nginx 鏡像

FROM nginx:alpine

# If you have a bundle of config created by DO config file, 
# you can copy them all to overwrite all the settings.
# or use
# to overwrite a single file
# COPY my-site-config.conf /etc/nginx/conf.d/default.conf

更新您的 docker-compose 以使用您的自定義版本的 nginx 映像

version: '3'
services:

#PHP Service
app:
 build:
  context: .
  dockerfile: Dockerfile
 image: digitalocean.com/php
 container_name: app
 restart: unless-stopped
 tty: true
 environment:
   SERVICE_NAME: app
   SERVICE_TAGS: dev
 working_dir: /var/www
 networks:
  - app-network

#Nginx Service
webserver:
 build:
   context: .
   dockerfile: Dockerfile.nginx
 container_name: webserver
 restart: unless-stopped
 tty: true
 ports:
  - "8027:80"
  - "443:443"
 networks:
  - app-network

似乎您缺少 Docker 如何工作以及如何使用多容器環境的一些關鍵部分，對於初學者，我建議您從一個像這樣的工作模板開始（閱讀所有頁面以了解綁定掛載點的含義）正如您所看到的app（PHP 容器）和webserver通過綁定掛載訪問文件的方式，此模板還為您提供了在不建構新容器的情況下覆蓋 php 配置和 nginx 的選項。

version: '3'
services:

 #PHP Service
 app:
   build:
     context: .
     dockerfile: Dockerfile
   image: digitalocean.com/php
   container_name: app
   restart: unless-stopped
   tty: true
   environment:
     SERVICE_NAME: app
     SERVICE_TAGS: dev
   working_dir: /var/www
   volumes:
     - ./:/var/www
     - ./php/local.ini:/usr/local/etc/php/conf.d/local.ini
   networks:
     - app-network

 #Nginx Service
 webserver:
   image: nginx:alpine
   container_name: webserver
   restart: unless-stopped
   tty: true
   ports:
     - "80:80"
     - "443:443"
   volumes:
     - ./:/var/www
     - ./nginx/conf.d/:/etc/nginx/conf.d/
   networks:
     - app-network

 #MySQL Service
 db:
   image: mysql:5.7.22
   container_name: db
   restart: unless-stopped
   tty: true
   ports:
     - "3306:3306"
   environment:
     MYSQL_DATABASE: laravel
     MYSQL_ROOT_PASSWORD: your_mysql_root_password
     SERVICE_TAGS: dev
     SERVICE_NAME: mysql
   volumes:
     - dbdata:/var/lib/mysql/
     - ./mysql/my.cnf:/etc/mysql/my.cnf
   networks:
     - app-network

#Docker Networks

 app-network:
   driver: bridge
#Volumes
volumes:
