Stories in Ready ## Roco

Command line tool allows you to execute commands on remote server(s) or locally. Useful for deployment, monitoring and other tasks.

Installation

npm install roco -g

Usage

roco deploy:setup   # prepare deploy (create directories)
roco deploy         # update code and restart server

Configuring

Use one of three ways for configuring your app: package.json, roco.coffee or ENV vars

package.json

roco looking for package.json in working directory and set these variables:

  • pkg.name as application
  • pkg.repository.name as repository
  • pkg.repository.type as scm

Roco.coffee

roco looking for Roco.coffee file in /etc/roco.coffee, ~/.roco.coffee, ./Roco.coffee, ./config/Roco.coffee paths

This files can extend behavior of roco and configure variables. Checkout examples to learn how to use it

ENV vars

  • HOSTS - comma separated list of hosts
  • APP - name of application

Examples

my ~/.roco.coffee file

namespace 'deploy', ->
    # show status of running application
    task 'status', ->
        run "sudo status #{roco.application}"
 
namespace 'git', ->
    # setup remote private repo
    task 'remote', ->
        app = roco.application
        run """
        mkdir #{app}.git;
        cd #{app}.git;
        git --bare init;
        true
        """, (res) ->
            localRun """
            git remote add origin #{res[0].host}:#{app}.git;
            git push -u origin master
            """
 
# some tasks for monitoring server state
namespace 'i', ->
    task 'disk', (done) -> run 'df -h', done
    task 'top',  (done) -> run 'top -b -n 1 | head -n 12', done
    task 'who',  (done) -> run 'who', done
    task 'node', (done) -> run 'ps -eo args | grep node | grep -v grep', done
    task 'free', (done) -> run 'free', done
 
    task 'all', (done) ->
        sequence 'top', 'free', 'disk', 'node', done
 
    # display last 100 lines of application log
    task 'log', ->
        run "tail -n 100 #{roco.sharedPath}/log/#{roco.env}.log"

Deploy

Current deploy script allows you deploy upstart-controlled applications out of box, just run

roco deploy:setup:upstart

to setup upstart script and create dirs, if you use another solution for node daemon management feel free to rewrite start/stop/restart scripts:

namespace 'deploy', ->
    task 'start', (done) -> run "cd #{roco.currentPath}; forever start server.js"
    task 'stop', (done) -> run "cd #{roco.currentPath}; forever stop"

Another snippets

Update nodejs on server(s)

~/.roco.coffee:

set 'nodever', '0.8.10'
namespace 'node', ->
  task 'update', (done) -> sequence 'download', 'unpack', 'compile', 'install', done
  task 'rebuild', (done) -> sequence 'unpack', 'compile', 'install', done
  task 'download', (done) ->
    run "cd /tmp && wget http://nodejs.org/dist/v#{roco.nodever}/node-v#{roco.nodever}.tar.gz", done
  task 'unpack', (done) ->
    run "cd /tmp && tar xfv node-v#{roco.nodever}.tar.gz", done
  task 'compile', (done) ->
    run "cd /tmp/node-v#{roco.nodever} && ./configure && make", done
  task 'install', (done) ->
    run "cd /tmp/node-v#{roco.nodever} && sudo make install", done

Example: update nodejs on localhost and railwayjs.com hosts

HOSTS=localhost,railwayjs.com roco node:update
