I have been doing my challenge in K8s Level2 “11. Fix issue with LAMP Environment in Kubernetes”. I’m facing some error below. Coud you help me resolve this task.
" One of the DevOps team members was trying to insta
ll a WordPress website on a LAMP stack, which is deployed on a Kubernetes cluster. It was working well, and we could see the installation page a few hours ago. However, something seems to have gone wrong with the stack after the website went down. Please look into the issue and fix it:
FYI, the deployment name is lamp-wp and it is using a service named lamp-service. Apache is using the default HTTP port, and the NodePort is 30008. From the application logs, it has been identified that the application is facing some issues connecting to the database, in addition to other problems. Additionally, there are some environment variables associated with the pods, such as MYSQL_ROOT_PASSWORD, MYSQL_DATABASE, MYSQL_USER, MYSQL_PASSWORD, and MYSQL_HOST
Also, do not attempt to delete or modify any other existing components, such as deployment names, service names, types, labels, secrets and so on."
You need to exec into the PHP container and update the inv vars in /app/index.php within the container and restart the PHP service.
I think you also need to update the Service for the appropriate port as well.

Pasting the YAML removes all the indentation, making it hard to read and comprehend.
As I mentioned, you need to exec into the PHP container, and update the env vars aligning with the ones defined in the Deployment.
