Container platforms (docker, lxc, podman)

I am trying to create a podman compose of NGINX and PHP:FPM. I was able to get NGINX to work on its own using the docker.io./bitnami/nginx image. I gotten close I believe to getting the PHP:FPM to work also but due to an issue with NGINX not cooperating with the PHP:FPM.

In the logs of the NGINX container, I get this error every time I load localhost:8080 in the browser...

10.89.4.2 - - [24/Jul/2024:20:18:35 +0000] "GET / HTTP/1.1" 404 47 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:128.0) Gecko/20100101 Firefox/128.0" "-"
2024/07/24 20:18:35 [error] 44#44: *1 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 10.89.4.2, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://10.89.4.3:9000", host: "localhost:8080"

And when I load localhost:8080 in the browser, it displays a blank page which says "File not found.".

I am using podman 5.1.2 on Linux Mint 21.3. My goal is to simply NGINX and PHP to work, to be able to have a web server that can use PHP.

Any advice would be most appreciated.
