- bitnami/nginx + bitnami/phpfpm: "File not found." When I load localhost:8080 in browser.
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.

- php with xdebug: Unable to debug console PHP in Visual Studio Code when using podman (Works in Docker)
I am unable to get the VSCode debugger to work with PHP running in a podman container. I was able to set this up using Docker by following these steps...
- Create php.dockerfile (Dockerfile)
- Create php.ini
- Add VSCode debugging launch configuration to VSCode settings.json
- Create container in Docker
- Start container
- Open workspace folder of the PHP script in VSCode
- Add breakpoints in the PHP script in VSCode
- Start Debugger in VSCode
- Run PHP script in docker container which will trigger the debugger in VSCode
I believe it is due to some networking setup with Podman which requires additional configuring for the debugger attach itself to the PHP script in the Podman container.
Any help will be most appreciated.

- Create alpine container that runs executable in volume directory?
Is it possible to run a alpine image to run an executable that is inside a volume without creating a new image? In Podman Desktop, I placed the following values in these fields when running the alpine image into a new container.
Command
/bin/sh -c /server/application
Volumes
~/Documents/server-data:/server
Ports
8080:8080
However I always get this error in my container logs. I think it could be due to the fact the container does not have permission to execute /server/application?
/bin/sh: /server/application: not found
- Windows: Add docker alias?
Is there way on windows to add an alias for commands in powershell and command prompt?
I want to make it so when I enter
docker

I was able to achieve this easily on Linux to were I can always enter
docker
and it will executepodman
, even if I closed the terminal window or rebooted my machine. It was a permanent alias redirect, not a temporary one.Can this be done on Windows for powershell and command prompt?
