Message:

I don't remember what I was trying to test but I always got the following message when I tried to access the root of my server (index.php) : The requested resource / was not found on this server.

So after several attempts, I managed to access it using docker-compose but not with only a Dockerfile.

I'm trying to understand why.

Dockerfile attempt (not working)

|--- Dockerfile

|--- index.php

My Dockerfile :

FROM php:8.1-alpine

COPY . /usr/src/myapp

CMD [ "php", "-S", "0.0.0.0:8000"]

Docker commands :

docker build -t docker_dockerfile_php .

docker run -p 8002:8000 docker_dockerfile_php

Now when I try to access localhost:8002, I have the following message : The requested resource / was not found on this server.

Docker compose attempt (working)

|--- docker

     |--- php

          |--- Dockerfile

|--- docker-compose.yml

|--- index.php

My Dockerfile :

FROM php:8.1-alpine

WORKDIR /usr/src/myapp

CMD [ "php", "-S", "0.0.0.0:8000"]

My docker-compose.yml :

services:

  php:

    image: docker_compose_php

    build: ./docker/php

    ports:

      - 8001:8000

    volumes:

      - ./:/usr/src/myapp

Docker commands :

docker-compose build

docker-compose up

Now when I try to access localhost:8001, I can acces my index.php file.

With the Docker compose attempt, I can use Xdebug on VSC with .devcontainer.

If anyone can enlighten me, I would be grateful.

My Answer:
"php", "-S", "0.0.0.0:80", "-t", "/usr/src/myapp" ]_

With this Dockerfile, I was not able to access the root of my server. I kept getting the "The requested resource / was not found on this server" message.

However, when I used a docker-compose.yml file with the following content, I was able to access the root of my server without any issues:

yaml
version: '3'
services:
web:
build: .
ports:
- "8080:80"


I ran `docker-compose up` and was able to access my server at `http://localhost:8080`.

I'm not sure why the Dockerfile alone did not work for me, but using docker-compose seemed to solve the issue.
