php-deploy

php-deploy is a full php deployment tool designed to allow very common OR very specific tasks. It's main philosophy is to chain commands as described in a simple configuration file, commands are easily extensible and highly customizable.

Installation using composer

If you use composer you can easily use it on your project. The main binary file will be available on your binary path bin/pdeploy and ready to use.

composer require alwex/phpdeploy

Initiating the project

To use php-deploy you have to initialize your project. Some directory and basic configuration files will be created under the .php-deploy directory located in the root of your project.

bin/pdeploy config:init myproject

• .php-deploy/config.ini -> the main configuration file which describe the global project configuration
• .php-deploy/environments -> environment configuration files goes here
• .php-deploy/Command -> you put your custom commands here

You may want to modify the config.ini file

Adding some environments

In order to add environments simply type

bin/pdeploy config:addenv production

Environment file example:

# user used for all remote commands
login=mySshLogin

# directory where the project is located
# relatively to the path where you execute
# bin/pdeploy
fromDirectory = ./
# remote or local path where to deploy
# the application
toDirectory = /var/www
# list of hosts where to deploy the app
hosts[] = 'localhost'
hosts[] = 'web1'
hosts[] = 'web2'
# ...
# name of the symlink allowing
# multiple apps in the same path
symlink = current-php-deploy

[deploy]
# PRE TASK
# executed before task
# usually vcs export and build
# of the package to deploy
preTask[] = Deploy\Command\GitExport
preTask[] = Deploy\Command\ComposerInstall
preTask[] = Deploy\Command\TarGz
# deployment stage executed against
# each hosts
onTask[] = Deploy\Command\Scp
onTask[] = Deploy\Command\UnTarGz
# post deployment stage executed
# on each hosts, usually cache clear,
# apache reload and symlink generation
# after this stage, deployment is done!
postTask[] = Deploy\Command\Symlink
# after tasks executed one time only
afterTask[] = ExampleCommand # custom comand

[mytask]
# PRE TASK
preTask[] = Deploy\Command\Symlink
# ON TASK
onTask[] = Deploy\Command\Symlink
# POST TASK
postTask[] = Deploy\Command\Symlink
# AFTER TASK
afterTask[] = Deploy\Command\Symlink

# ... and so on as many tasks as necessary

Executing a task

Once you have defined the tasks on the environment ini files, you can simply run them with

bin/pdeploy task:run --release=0.0.1 --env=production mytask

Creating custom commands

To add custom commands, simply add it as php classes on the folder .php-deploy/Command, you can duplicate the ExampleCommand.php to start. Just add this custom command to a task like for example

afterTask[] = ExampleCommand

ExampleCommand content:

class ExampleCommand extends \Deploy\Command\AbstractCommand {

    /**
     * optionally you may check if all the
     * requirement are met before running
     * the command
     *
     * @throw \RuntimeException
     */
    public function beforeRun() {

        if (file_exists("/tmp/hello.txt")) {
            throw new \RuntimeException("hello file already exists");
        }
    }

    /**
     * execute command and php tasks
     * return the execution status as an integer
     *
     * @return void
     */
    public function run()
    {
        $command = "echo hello > /tmp/hello.txt";
        $this->shellExec($command);
    }

    /**
     * optionally you may check if the command has been
     * correctly done
     *
     * @throw \RuntimeException
     */
    public function afterRun() {

        $expectedValue = 'hello';
        $fileContent = file_get_contents("/tmp/hello.txt");

        if ($fileContent != $expectedValue) {
            throw new \RuntimeException("hello file does not contain expected value '$expectedValue', found '$fileContent'");
        }
    }
}
