node package manager


Deploy app to remote server via ssh

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

npm install roco -g
roco deploy:setup   # prepare deploy (create directories)
roco deploy         # update code and restart server

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

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

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

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

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

  • HOSTS - comma separated list of hosts
  • APP - name of application
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;
        """, (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"

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"


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{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 hosts

HOSTS=localhost, roco node:update
