Kubernetes Nginx php-fpm deployment
Kubernetes is a container orchestration platform that allows you to deploy, manage, and scale containerized applications. Nginx is a popular open-source web server that can also function as a reverse proxy, load balancer, and HTTP cache. PHP-FPM is a FastCGI Process Manager for PHP that helps to handle high traffic websites by managing the PHP process.
When deploying a PHP application on Kubernetes with Nginx and PHP-FPM, you typically create separate deployments for each component. For example, you may create a deployment for the PHP-FPM backend and a separate deployment for the Nginx frontend.
In the PHP-FPM deployment, you would define a container that runs the PHP-FPM process and mounts the application code as a volume. You may also need to define environment variables, such as database connection information, that the PHP code can use.
In the Nginx deployment, you would define a container that runs the Nginx process and mounts the application code as a volume. You would also define a configuration file for Nginx that specifies the PHP-FPM backend as a FastCGI server, along with any other Nginx settings that your application requires.
To connect the Nginx frontend to the PHP-FPM backend, you would typically use a Kubernetes service. The service allows the Nginx container to communicate with the PHP-FPM container, even if they are running on different nodes in the Kubernetes cluster.
Once you have defined the deployments, containers, and services for your application, you can use Kubernetes commands to deploy and manage the application in the cluster. For example, you can use the kubectl apply command to apply a YAML configuration file that defines your application components, and the kubectl scale command to scale the application up or down based on demand.
