deployer

Set up a deploy user with the necessary ssh authorized keys. This is great for working with Capistrano where you need to deploy code, but it doesn't make sense for each user to have a shell account.

This cookbook will create a deployment user (deploy by default) with passwordless-sudo permissions for deployment. As a result, it is highly recommended that you disable password authentication and only support key-based authentication.

Requirements

At this time, you must have a Unix-based machine. This could easily be adapted for Windows machines. Please submit a Pull Request if you wish to add Windows support.

Configuration

There are three attributes that you can override in your node:

• node['deployer']['user'] - the name of the deploy user (default: deploy)
• node['deployer']['group'] - the group for the deploy user (default: deploy)
• node['deployer']['home'] - the home directory for the deploy user (default: /home/deploy)

Adding keys

There are two ways to add keys to the deployer. If you're using the opscode users cookbook, deployer easily integrates with the existing :users data_bags. Simply add the servers key to an existing user:

// data_bags/users/svargo.json
{
  "id": "svargo",
  "uid": "1000",
  "deploy": "any"
}

or specify an array of servers or IP addresses that the user should be allowed to deploy to:

// data_bags/users/svargo.json
{
  "id": "svargo",
  "uid": "1000",
  "deploy": [
    "1.2.3.4",
    "mynode.example.com"
  ]
}

If you're not using the users cookbook, or if you have a conflict, you can use the :deployers data_bag instead:

Create the data_bag:

knife data bag create deployers

Create a deployer:

// data_bags/deployers/svargo.json
{
  "id": "svargo",
  "deploy": [
    "1.2.3.4",
    "mynode.example.com"
  ]
}

The same options apply to the servers key as above. Note: this will not actually create system user accounts.

Usage

If you're using Berkshelf, just add deployer to your Berksfile:

cookbook 'deployer'

Otherwise, install the cookbook from the community site:

knife cookbook site install deployer

Have any other cookbooks depend on deployer by editing editing the metadata.rb for your cookbook.

depends 'deployer'

Once you have the cookbook installed, add it to your node's run_list or role:

"run_list": [
  "recipe[deployer]"
]

And override attributes as necessary:

# mynode.example.com
"override_attributes": {
  "deployer": {
    "user": "apache",
    "group": "apache",
    "home": "/usr/bin/false"
  }
},
"run_list": [
  "recipe[deployer]"
]
