Rails and Sinatra deployment made easy

ABOUT:

Inploy was born as an option to setup and deploy Rails applications in an easier and smarter way.

It automatically executes common tasks like migrate the database, install gems, package the assets, clean the cache, notify Hoptoad, restart the server, etc. This means you will not have a big deploy script calld ‘recipe’ like with other tools, only a simple deploy script with a few lines.

It uses Git to version the deploys and to pull or push only the modifications in each one. This means you will not have a lot of folders in the server (only one) with duplicated code and that ech deploy will be very fast.

It is very flexible, meaning you can create templates specifing how specific tasks must behave. As today, there are templates for Locaweb, for Rails 3 using git pull and Rails 3 using git push.

It works by default with Passenger, but you can specify another servers like Mongrel, Thin and Unicorn.

You can execute Inploy from a remote machine or from the server machine, meaning anynone can go to the deployment path and with only one command update the code and execute all the tasks.

As Inploy is very flexible, now you can also use it to execute an installation shell script in a server from an URL.

INSTALLATION:

As a plugin:

script/plugin install git://github.com/dcrec1/inploy.git

As a gem:

sudo gem install inploy

Please remember that when used as a gem, Inploy should be available in the deploy servers.

Rails 2.3.x note

When using rails 2.3.x, you should include the follow line into you Rakefile:

##### Rakefile
load "tasks/inploy.rake"

USAGE

When using Inploy with Rake, there are five tasks:

  • inploy:remote:install from=url

- connects to a list of servers and executes the script from url

  • inploy:remote:setup

- connects to a list of servers
- clones a git repository
- executes rake inploy:local:setup

  • inploy:remote:update or inploy:up

- connects to a list of servers
- executes inploy:local:update

  • inploy:remote:install

- connects to a list of servers
- reads the content of url specified by from=url without downloading the file and executes it

  • inploy:local:setup

- creates directories db and tmp/pids
- copies config/.[example|sample|template] files to config/
- creates the database
- executes init.sh file case it exists
- inits and updates the git submodules
- installs gems
- migrates the database
- updates the crontab from Whenever if being used
- cleans the cache, default tmp/cache
- cleans cached assets in public/assets if Jammit is installed
- starts the Delayed Job worker if script/delayed_job exist
- parses less files if more:parse task exists
- parses compass files if config/initializers/compass.rb exists
- parses coffeescript files with Barista if barista:brew task exist
- package the assets if asset:packager:build_all task exists
- notifies Hoptoad about the deploy, specifing the revision, repository and environment
- notifies NewRelic RPM about the deploy
- restarts the server

  • inploy:local:update

- pulls the repository
- inits and updates the git submodules
- copies config/.[example|sample|template] files to config/
- installs gems
- migrates the database
- updates the crontab from Whenever if being used
- cleans the cache, default tmp/cache
- cleans cached assets in public/assets if Jammit is installed
- restarts the Delayed Job worker if script/delayed_job exists
- parses less files if more:parse task exists
- parses compass files if config/initializers/compass.rb exists
- parses coffeescript files with Barista if barista:brew task exist
- package the assets if asset:packager:build_all task exists
- notifies Hoptoad about the deploy, specifing the revision, repository and environment
- notifies NewRelic RPM about the deploy
- restarts the server

If you don’t want to execute Rake, there are a few shortcuts:

inploy => inploy update => rake inploy:remote:update
inploy setup => rake inploy:remote:setup
inploy install from=url => rake inploy:remote:install from=url

When using inploy as a command, it looks first for config/deploy.rb and then for deploy.rb .

CONFIGURATION

Create a config/deploy.rb file and configure it something like this:

application = "signal"
repository = 'git://github.com/dcrec1/signal.git'
hosts = ['hooters', 'geni']

# OPTIONALS

before_restarting_server do
  rake "important:task"
  run "important_command"
end

path = '/opt'                                # default /var/local/apps
user = 'dcrec1'                              # default deploy
ssh_opts = '-A'                              # default empty
branch = 'new_version'                       # default master
environment = 'staging'                      # default production
sudo = true                                  # default false
cache_dirs = ['public/cache', 'tmp/cache']   # default ['public/cache']
skip_steps = ['install_gems', 'clear_cache'] # default []
app_folder = 'project_folder'                # default empty
login_shell = true                           # default false
bundler_opts = '--binstubs'                  # default '--deployment --without development test cucumber'

The bundler_path option has been removed. To migrate your existing config/deploy.rb file simply replace bundler_path = '/path/to/gems' with bundler_opts = '--path /path/to/gems'

SKIP STEPS

You can skip some steps when running a Rake task, just add “skip_steps” into your rake command line or add “skip_steps” to your deploy.rb to always skip those steps.

Currently the steps available to skip are:

- copy_sample_files: skip copying config/.[example|sample|template] files to config/
- install_gems: skip rake gems:install
- migrate_database: skip rake db:migrate
- clear_cache: skip removing cache directories
- update_crontab: skip updating the crontab with Whenever

  • Usage (params are comma separated):
rake inploy:remote:update skip_steps=install_gems,migrate_database

HOOKS

Currently, the following three hooks are available:

- before_git (not called before initial git clone)
- after_git
- after_setup
- before_restarting_server
- after_restarting_server

To show a “down for maintenance” page during the deployment, use the before_git and after_restarting_server hooks.

If you need another hook, please fork the project and implement it. Or submit an issue, it’s very easy.

say

Use the say method to show messages issued by your hooks.

# Show a simple message
say 'restart custom daemons'

# Show a message (blank output lines are suppressed)
say 'revert local changes' do |output|
  output << `git checkout . 2>&1`
end
