The [project:deploy|INFO] task deploys a project on a server:

  [./symfony project:deploy production|INFO]

The server must be configured in [config/properties.ini|COMMENT]:

  [[production]
    host=www.example.com
    port=22
    user=fabien
    dir=/var/www/sfblog/
    type=rsync|INFO]

To automate the deployment, the task uses rsync over SSH.
You must configure SSH access with a key or configure the password
in [config/properties.ini|COMMENT].

By default, the task is in dry-mode. To do a real deployment, you
must pass the [--go|COMMENT] option:

  [./symfony project:deploy --go production|INFO]

Files and directories configured in [config/rsync_exclude.txt|COMMENT] are
not deployed:

  [.svn
  /web/uploads/*
  /cache/*
  /log/*|INFO]

You can also create a [rsync.txt|COMMENT] and [rsync_include.txt|COMMENT] files.

If you need to customize the [rsync*.txt|COMMENT] files based on the server,
you can pass a [rsync-dir|COMMENT] option:

  [./symfony project:deploy --go --rsync-dir=config/production production|INFO]

Last, you can specify the options passed to the rsync executable, using the 
[rsync-options|INFO] option (defaults are [-azC|INFO]):

  [./symfony project:deploy --go --rsync-options=avz|INFO]
