node-deploy

node-deploy is a tool for deploying a node web app to an upstart+nginx machine automatically.

Installation

npm

npm install -g node-deploy

GitHub

npm install -g https://github.com/martinrue/node-deploy/tarball/master

Prerequisites

The remote machine must have git, nginx, node and npm installed before deployments can be made to it. The machine should also be configured for remote access via ssh.

Usage

usage: nd [init | deploy | remove] -b <branch> -d <directory>

• Run nd init to generate the deploy config files. You need to commit and push these files before deploying.
• Run nd deploy to begin a deployment.
• Run nd remove to stop and remove the app from the server.

Options

-b <branch>

node-deploy will deploy from the master branch. Use -b <branch> to deploy a different branch. The new branch will be deployed over the same application – it's just a means of deploying from an alternative branch.

-d <directory>

Config files are stored in the deploy directory unless you specify a custom directory via -d <directory>. Example: nd deploy -d deployconfigs

Example

First run nd init and answer the questions. It will try to guess some settings for you – if you're happy with the guess, just hit enter to accept it:

node v0.10.8 in ~/Desktop/app on master
→ nd init
app url: martinrue.com
app name (app): martinrue.com
app start command (node blog.js):
upstream port (4001):
app path on server (/var/www):
nginx sites-enabled path (/etc/nginx/sites-enabled):
git clone URL ([e-mail]:martinrue/delme.git):
server SSH address: root@192.168.2.4

Second, commit and push the newly created config files:

node v0.10.8 in ~/Desktop/app on master
→ git add -A
 
node v0.10.8 in ~/Desktop/app on master
→ git commit -m "add deploy config"
[master 9a0def5] add deploy config
 3 files changed, 30 insertions(+)
 create mode 100644 deploy/deploy.json
 create mode 100644 deploy/martinrue.com
 create mode 100644 deploy/martinrue.com.conf
 
node v0.10.8 in ~/Desktop/app on master with unpushed
→ git push

   b973149..9a0def5  master -> master

And finally, deploy:

node v0.10.8 in ~/Desktop/app on master
→ nd deploy
deploying master to root@192.168.2.4:/var/www/martinrue.com

Questions

After running nd init, you'll be asked a series of questions. Here's what each answer is used for:

app url

This is the public URL your app will be served from.

Example: martinrue.com

app name

Specifies the name of the app directory and the nginx/upstart config files.

Example: martinrue.com

app start command

The command used to start the application on the server.

Example: node app.js

upstream port

The port the node app listens on. This is needed to properly link the node process with the upstream nginx server.

Example: 1234

app path on server

The directory the app will be cloned into and run from on the server.

Example: /var/www

nginx sites-enabled path

The path of the nginx sites-enabled directory. The nginx config file will be copied here.

Example: /etc/nginx/sites-enabled

git clone URL

The URL of the repo. The repo is cloned on the first deploy and then pulled from thereafter.

Example: [e-mail]:martinrue/martinrue.com.git

server SSH address

The SSH user + host address of the server. You can specify a non-22 SSH port number by using a : after the hostname.

Example: [e-mail]:3022

Notes

• Following a successful deploy, nd will wait a further 15 seconds (to account for the configured respawn limits of upstart) to verify the app process is still alive and well.

• As a shorthand, the nd init, nd deploy, nd remove commands can also be referred to by their first letter, i.e. nd i, nd d and nd r respectively.

• If no errors are reported, the command was successful. The appropriate zero or non-zero error code is returned to allow nd to be invoked by third party tools.

• It's assumed that all files in the sites-enabled nginx directory are valid config files, i.e. that your nginx.conf includes them using something like this include /etc/nginx/sites-enabled/*;.
