Hello all,

I did solve it using chatGPT, I’ve been retrying the steps it doesn’t work. It worked only twice. I don’t know what the solution is or what issue in the question has to be addressed. Can someone help me with it, please?

Question

We encountered an issue with our Nginx and PHP-FPM setup on the Kubernetes cluster this morning, which halted its functionality. Investigate and rectify the issue:

The pod name is nginx-phpfpm and configmap name is nginx-config. Identify and fix the problem.

Once resolved, copy /home/thor/index.php file from the jump host to the nginx-container within the nginx document root. After this, you should be able to access the website using Website button on the top bar.

Note: The kubectl utility on jump_host is configured to operate with the Kubernetes cluster.

# Resolve Volume Mounts Issue in Kubernetes

Despite the title, the issue here is not entirely the volume mount itself, but also the content of the configmap which is being mounted. The site is not working because the nginx configuration in the configmap is incorrect.

**HINT** - This is all about the path to where the web server files are stored which is an emptyDir volume mounted in both containers. The mount paths to this from both containers and also the root path in the nginx configuration contained in the configmap must all be in agreement. Once that is fixed and you then copy the PHP file into the directory which is the emptyDir volume, then it will pass.

1. Inspect the pod

    ```
    kubectl describe pod nginx-phpfpm
    ```

    Note the following

    * It has 2 containers - `php-fpm-container` and `nginx-container`.
    * Both containers share an emptyDir volume which is where the website files go.
    * `nginx-container` has an additional volume mounted from the config map which contains the config file for nginx.
