In this post, we'll play with Docker and Java. Since there are ready-to-use Java images for Docker you don't need to install or configure anything other than Docker.
You just need to know, I've absolutely no skills in Java. Which software should be installed, how to run a script and so on. I'll just rely on a very few Docker commands and, about the installation, yeah, using Docker, it's easy: nothing to install, nothing to configure.
But what a joy it is to be able to draw diagrams by, well, just writing text. Some tools are better known than others, e.g. Mermaid.
Did you know https://diagrams.mingrammer.com/? Let's explore it using, of course, a Docker ready-to-use image.
When working with a Docker container, data can be persistent or not. Imagine you're creating a localhost website with Joomla, Wordpress or any other tool (Laravel, Symfony, etc.).
You've perfectly created the various Docker files needed to run the local site, you've run the command docker compose up --detach to start the containers and now you're busy installing the site. After a few moments, your local site is up and you can start developing its functionalities.
By default, if you haven't taken any precautions, the moment you stop the container (docker compose down), you'll kill your site, i.e. by default, having not taken care to save your data (your site, your database), everything will be lost and reset the next time you run docker compose up --detach. Well... Maybe that was your wish (something totally ephemeral); maybe not;
Version updated on November 21, 2023 after a discussion with Alexandre about making his Docker image available on hub.docker.com
Based on their documentation, FrankenPHP is 3.5 faster than PHP FPM.
It is still fairly young for use on production sites, but because it's so promising, it's certainly worth playing with when developing locally.
Alexandre Elisé has written a script to use FrankenPHP with Joomla. You can find the source here: https://github.com/alexandreelise/frankenphp-joomla.
In this article, we will learn how to use Docker to install Joomla on your localhost and start a new website in seconds (don't want to wait? Jump to the Final docker-compose.yml chapter).
I will use a Linux console (I'm running WSL on my Windows computer and I have chosen Ubuntu for my distribution) but since Docker can also be used on Windows, you can perfectly run, exactly, the same commands in an MS-DOS / Powershell console.
If you don't have Docker yet, please consult my Install Docker and play with PHP post first.
When running Docker without specifying a volume, everything done during the execution of Docker is done in memory. In other words: if the PHP script you run from Docker creates folders or files, these will never be created on your disk. They will be created exclusively in memory.
Docker can be installed free of charge for personal or small-scale use: https://www.docker.com/products/personal/.
You can install it on Linux, Mac or Windows.
The easiest way, under Windows, is to use Docker Dekstop.

By default, the Linux distribution is installed on your C: drive. If, like me, you have a D: drive with almost nothing on it, it can be really interesting to move Linux on that second drive.
Updated 2023-11-03, search engine, prism and sitemap added. Updated 2023-11-05, adding giscus.
Here are the steps I followed to create this blog.

When WSLg is enabled, it's possible to access to the graphical user interface of your Linux distribution (in my case, it's Ubuntu).
If you don't have xrdp yet, you can install it by running:
sudo apt update && sudo apt -y upgrade
sudo apt-get install -y xrdp
