Configure kind cluster with wildcard domains on Ubuntu

Installing the kind cluster with an Ingress Controller is pretty easy task for Ubuntu. But configuring opening Ingress domains by wildcard locally - already not so easy! So, let's describe the steps on how to do this! It's tested by me on Ubuntu 22.04 and 23.10, but should work well for other versions too.

Fortunately, modern Ubuntu versions use systemd-resolved for DNS resolving, that have the dnsmasq feature built-in, so you don't need to install the dnsmasq as a separate package.

Workaround to make a Drupal module compatible with D9 and D10 together

The Drupal 10 release, as described, is mostly about deprecations and removing old code. So it's pretty easy to port your modules to Drupal 10, they said!

But actually - not!

Together with deprecations, we have some libraries updated to the new major versions too, and this can bring you little unexpected surprises when you try to make your module compatible with both Drupal 9 and 10 versions together.


Launch VS Code IDE inside a Docker container


  • You don’t even need to install the language package (PHP, Node.js, Go, etc) and all other tools locally on your host system, you only need to have the VS Code app (or even Free/Libre Open Source VS Codium app).
  • You'll got a native app experience with local graphical interface, but all operations are performed inside the container.

How to create a custom Drupal Entity Type in a single PHP file

Most of instructions about creating a new custom Drupal Entity Type describes that you need to create a lot of files: routing, links, form, list builder, interfaces, etc.

But if you need to create just a simple custom Content Entity Type for your own needs and with mostly default functionality, you can simply describe it in a one PHP file, with reuse of Drupal Core classes for all other functionality (User Interface, Permissions, List Builder, etc)!

Here is the example:

Using systemd as user service manager with systemctl and journalctl in userspace

Common systemd usage is to manage global linux services, that can be created/modified only with root/sudo credentials.

But systemd have the great user mode, that allow to create and control any services without sudo permissions, that runs as user owner, we simply need to add the `--user` argument.

For allow to start user services on system boot, you must one-time launch the command for needed user: sudo loginctl enable-linger LOGIN


Delete all available tables on PostgreSQL database without schema permissions

How to eval PHP code via drush without escaping quotes routine

Very often there is a need to execute via drush eval command the PHP code with both single and double quotes, something like this:

echo "Hello, '$username'!"; 

This can be quickly done without manually adding slashes to each quote in PHP code via this bash trick:

PHP=`cat <<'EOF'
echo "Hello, '$username'!"; 
EOF`; drush ev "$PHP"

Instead of single line of PHP code, you can insert long multi-line part of code, without carrying about escaping quotes.
