Capistrano extends the Rake DSL with methods specific to running commands on() servers.. For Any Language. Capistrano is written in Ruby, but it can easily be used to deploy any language. If your language or framework has special deployment requirements, Capistrano can easily be extended to support them.INSTALLATION

What is Capistrano? Capistrano is a remote server automation tool. It supports the scripting and execution of arbitrary tasks, and includes a set of sane-default deployment workflows. PROPERTIES - CAPISTRANO Properties. Server objects in Capistrano essentially consist of a name and a hash: The name is the DNS name (or IP address) and the hash contains the ‘Properties’ of the server. COLD START - CAPISTRANO Cold Start. At this point we should have a deploy user on all the servers we intend to deploy to, that user should have permission to write to wherever we plan on deploying to, by default that’ll be something like /var/www/my-application.. We’ve set up the directory with decent permissions so that we can deploy without breaking things, and that everyone on our team can deploy, too.OFFICIAL PLUGINS

The question is deferred until the first time fetch is used to obtain the setting. That means you can ask for many variables, but only the variables used by your task(s) will actually prompt the user for input. REMOTE COMMANDS WITH SSH KIT Remote commands with SSH Kit. Capistrano executes commands on remote servers using SSHKit.. An example setting a working directory, user and environment variable:PROPERTY FILTERING
Property Filtering. Options may be passed to the roles() method (and implicitly in methods like release_roles() and primary()) that affect the set of servers returned.These options take the form of a Hash passed as the last parameter. Each of the key/value pairs in the hash are evaluated in the sequence they are declared and if all are true for a specific server then the server will be returned.VERSION LOCKING
Version Locking. Capistrano will, by default, include a lock command at the top of deploy.rb.This checks that the version of Capistrano running the configuration is the same as was intended to run it. HOW CAN I ACCESS STAGE CONFIGURATION VARIABLES? This works fine when accessing configuration variables defined within the same file. For example accessing a previously set configuration variable defined in deploy.rb or accessing a set configuration variable in a stage file.
