A deployment tool for php projects

tempo

, _(*1)

A deployment tool for php projects. Execute commands on local and remote nodes using php., _(*2)

Quick start

Install tempo into your project with composer:, _(*3)

composer require assimtech/tempo

Create a tempo.php file in the root of your project containing the following:, _(*4)

<?php

use Assimtech\Tempo;
use MyProject\Tempo\Command;

// Infrastructure
$infrastructureLoader = Tempo\Factory\InfrastructureLoaderFactory::create();
$infrastructure = $infrastructureLoader->load(__DIR__ . '/infrastructure.yml');

// Commands
$definition = new Tempo\Definition();
foreach ($infrastructure->getEnvironments() as $env) {
    $definition->addCommand(new Command\WhereAmI($env));
}

return $definition;

Then create a infrastructure.yml file containing the following:, _(*5)

nodes:
    server1:
        ssh:
            host: server1.example.com

environments:
    -
        name: test
        nodes: [ server1 ]

Change "server1.example.com" to a server you have ssh access to. If you need to change username / port etc, please see the documentation on how to setup a Node, _(*6)

Then create a MyProject\Tempo\Command\WhereAmI class containing the following:, _(*7)

<?php

namespace MyProject\Tempo\Command;

use Assimtech\Sysexits;
use Assimtech\Tempo\Command\AbstractCommand;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;

class WhereAmI extends AbstractCommand
{
    /**
     * {@inheritdoc}
     */
    protected function execute(InputInterface $input, OutputInterface $output)
    {
        foreach ($this->env->getNodes() as $node) {
            $output->write("<comment>Checking uname of $node: </comment>");
            $uname = $node->run('uname -a');
            $output->writeln("<info>$uname</info>");
        }

        return Sysexits::EX_OK;
    }
}

Run tempo from within the root of your project:, _(*8)

tempo test:whereami

Try adding more environments / servers / commands etc, _(*9)

Known issues

Running tempo from a docker container may cause connection problems

Due to an issue with the latest ssh version not playing nicely with overlayfs you may experience a connection sharing issue like: Control socket connect(...): Connection refused, _(*10)

If the script you are running seems to be authenticating again for each remote command or if you see the MOTD coming back in the response for each command this may also be the cause., _(*11)

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1262287, _(*12)

If you have this issue, you could specify your control master path as a standard filesystem location in your infrastructure.yml (anywhere in your container outside of a host directory volume):, _(*13)

nodes:
    server1:
        ssh:
            host: server1.example.com
            control:
                ControlPath: /tmp/%r@%h:%p

environments:
    -
        name: test
        nodes: [ server1 ]
