    [ref]                deploy to [ref], the 'ref' setting, or latest tag

Configuration

By default deploy(1) will look for ./deploy.conf, consisting of one or more environments, [stage], [production], etc, followed by directives.

[stage]
key /path/to/some.pem
user deployer
host n.n.n.n
port nn
repo git@github.com:visionmedia/express.git
path /var/www/myapp.com
ref origin/master
post-deploy /var/www/myapp.com/update.sh

Directives

key (optional)

Path to identity file used by ssh -i.

  key /path/to/some.pem

ref (optional)

When specified, HEAD is reset to ref. When deploying
production typically this will not be used, as deploy(1) will
utilize the most recent tag by default, however this is useful
for a staging environment, as shown below where HEAD is updated
and set to the develop branch.

    ref origin/develop

user

User for deployment.

   user deployer

host

Server hostname.

   host 50.17.255.50

port (optional)

Server port.

   port 22

repo

GIT repository to clone.

   repo git@github.com:visionmedia/express.git

path

Deployment path.

    path /var/www/myapp.com

forward-agent

Webhosts normally use read-only deploy keys to access private git repositories.
If you'd rather use the credentials of the person invoking the deploy
command, put forward-agent yes in the relevant config sections.
Now the deploy script will invoke ssh -A when deploying and there's
no need to keep SSH keys on your servers.

needs_tty

If your deployment scripts require any user interaction (which they shouldn't, but
often do) you'll probably want SSH to allocate a tty for you. Put needs_tty yes
in the config section if you'd like the deploy script to invoke ssh -t and ensure
you have a tty available.

Hooks

All hooks are arbitrary commands, executed relative to path/current,
aka the previous deployment for pre-deploy, and the new deployment
for post-deploy. Of course you may specify absolute paths as well.

pre-deploy

  pre-deploy ./bin/something

post-deploy

  post-deploy ./bin/restart

test

Post-deployment test command after post-deploy. If this
command fails, deploy(1) will attempt to revert to the previous
deployment, ignoring tests (for now), as they are assumed to have run correctly.

  test ./something
