Can I run cli commands in magento 2 through button or action or route?

Question

I want to run magento cli commands in magento 2.4.1 through button or action

Answer 1

Given the fact that is an extremely insecure practice, you can.

The fast way would be to pass directly through the Shell object:

use Magento\Framework\Shell;
use Magento\Framework\Shell\CommandRenderer;

// put in your constructor
public function __construct() {
    $this->shell = new Shell(new CommandRenderer());
}

// put in your action execute method
public function execute() {
    $command = 'php bin/magento setup:upgrade';
    $this->shell->execute($command);
}

A cleaner way would be to find the command implementation in the source code and execute it in your action/button. The CLI commands are classes which extend the Symfony\Component\Console\Command\Command class. Once called, such class performs the code inside the execute() method.

Thus, you can use:

// put in your constructor
public function __construct(
    <Vendor>\<Module>\<PathToCommandClass> $command
) {
    $this->command = $command;
}

// in your action
public function execute() {
    $command->execute();
}

where $command is passed in the action constructor as a dependency.
