Getting Started

First, let's install Deployer. Run next commands in terminal:

curl -LO
mv deployer.phar /usr/local/bin/dep
chmod +x /usr/local/bin/dep

Now you can use Deployer via the dep command. Open up a terminal in your project directory and run the following command:

dep init

This command will create deploy.php file in current directory. It is called recipe and contains configuration and tasks for deployment. By default all recipes extends common recipe.

Define your task really simple:

task('test', function () {
    writeln('Hello world');

To run that task, run next command:

dep test

And you get next output:

➤ Executing task test
Hello world
✔ Ok

Now lets create some task which will run commands on remote server. For that we must configure server. Your created deploy.php file should contain server declaration like this:

server('production', '')
    ->set('deploy_path', '/var/www/');

You can find more about servers configuration here. Now let's define task which will output pwd command from remote server:

task('pwd', function () {
    $result = run('pwd');
    writeln("Current dir: $result");

Run it dep pwd, and you will get this:

➤ Executing task pwd
Current dir: /var/www/
✔ Ok

Now lets prepare for our first deploy. You need to configure, such params as repository, shared_files and others:

set('repository', '');
set('shared_files', [...]);

You can get params value in tasks using get function. Also you can override each config for each server:

server('production', '')
    ->set('shared_files', [...]);

More about configuration can be found here.

Now let's deploy our application:

dep deploy

To see what exactly happening you can increase verbosity of output with --verbose option:

  • -v for normal output,
  • -vv for more verbose output,
  • -vvv for debug.

On first Deployer will create the following directories on the server:

  • releases contains releases dirs,
  • shared contains shared files and dirs,
  • current symlink to current release.

Configure your server to serve your public directory from current.

Note that deployer uses ACL by default for setting up permissions. You can change this behavior with writable_mode config.

By default deployer keeps last 5 releases, but you can increase this number by modifying parameter:

set('keep_releases', 10);

If something went wrong during the deployment process, or something is wrong with your new release, simply run the following command to rollback to the previous working release:

dep rollback

You may want to run some task before/after another tasks. Configuring that is really simple!

Let's reload php-fpm after deploy task finished:

task('reload:php-fpm', function () {
    run('sudo /usr/sbin/service php5-fpm reload');

after('deploy', 'reload:php-fpm');
