It's also possible to use PHP Docker with existing projects!
First, download this skeleton. If you clone the Git repository, be sure to remove the .git directory to prevent conflicts with the .git directory already in your existing project.
Then, copy the Docker-related files from the skeleton to your existing project:
cp -Rp php-docker/. my-existing-project/
Double-check the changes, revert the changes that you don't want to keep:
git diff
...
Build the Docker images:
docker compose build --no-cache --pull
Start the project!
docker compose up -d
Browse https://localhost, your Docker configuration is ready!
