devspace：从独特部署 PHP:apache 到 PHP-FPM + Nginx

Question

如何为 devspace 进行 PHPFPM+Nginx 部署？

实际上，我正在使用 PHP-Apache 并拥有这个 devspace.yaml

[...]
deployments:
- name: panel
  helm:
    componentChart: true
    values:
      containers:
      - image: registry.digitalocean.com/mycompany/myapp
      service:
        ports:
        - port: 80
      ingress:
        rules:
        - host: "mydomain.com.ar"

我的 Dockerfile 就像

FROM php:7.4.4-apache
[...]
EXPOSE 80
CMD ["apache2-foreground"]

一切正常，主机已在 Ingress 上注册。但是，我喜欢从 PHPApache 升级到 PHP-FPM + Nginx。

我将我的 Dockerfile 从 FROM php:7.4.4-apache 更改为 FROM php:7.4.4-fpm 并删除了 EXPOSE 和 COMMAND。但现在？现在不需要 PHP 和 NGinx 的特定配置。

那么，如何将nginx服务添加到devspace.yaml并连接到php-fpm？

Answer 1

您可以在一个 pod 中使用两个容器，一个用于 PHP-FPM，一个用于 Nginx。这样（因为它们在同一个 pod 中），它们可以通过端口 9000 轻松通信。

PHP 容器：

从php:7.4-fpm ...

Nginx 容器：

FROM nginx:1.9-高山 ...

确保在 Nginx 配置中包含 FPM：

location ~* \.php$ {
    fastcgi_index   index.php;
    fastcgi_pass    127.0.0.1:9000;
    include         fastcgi_params;
    fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
    fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
}

在“devspace.yaml”配置中，您将在图像节下列出它们。

您可以将网站数据挂载到两个容器；当心，你不能有多个 readOnly: false volume mount;在下面的代码片段中，都将其挂载为只读；如果你需要写，那么相应地改变。

deployments:
- name: my-component
  helm:
    componentChart: true
    values:
      containers:
      - name: nginx
        image: "nginx:1.9-alpine"
        volumeMounts:
        - containerPath: /var/www/html
          volume:
            name: website-data
            subPath: /website-data
            readOnly: true
      - name: php-fpm
        image: "php:7.4-fpm"
        volumeMounts:
        - containerPath: /var/www/html
          volume:
            name: website-data
            subPath: /website-data
            readOnly: true
      volumes:
      - name: website-data
        size: "5Gi"

      ingress:
        # tls: true
        rules:
          - host: "reyesoft.com"
[...]

nginx.conf:

server {

    # [...]

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    location ~ \.php$ {
        root           /usr/share/nginx/html/public/;

        include php_location.include/*.conf;

        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        # fastcgi_param  SCRIPT_FILENAME  /var/www/html$fastcgi_script_name;
        fastcgi_param   SCRIPT_FILENAME         $fastcgi_script_name;
        include        fastcgi_params;
    }
}
