sslmate Cookbook

A Chef cookbook for installing the sslmate command line utility. It also includes optional helper scripts for automating the purchasing, renewal, and installation of certificates in an AWS environment.

Attributes

Key	Type	Description	Default
`['sslmate']['git_repository']`	String	The git URL to fetch sslmate's source code from	`https://github.com/SSLMate/sslmate.git`
`['sslmate']['git_revision']`	String	The git tag, branch, or revision to install from	`0.6.2`
`['sslmate']['prefix']`	String	The installation prefix for sslmate	`/usr/local`
`['sslmate']['domains']`	Array	A list of domains to manage the SSL certificates for with the manage_domain recipe	`[]`

Usage

sslmate::default

The default recipe will install sslmate from source. Simply include it in your run list:

{
  "run_list": [
    "recipe[sslmate]"
  ]
}

sslmate::manage_domains

The manage_domains recipe will install sslmate and some additional helper scripts to automate purchasing, renewing, and installing certificates in an Amazon Web Services environment (currently it assumes SSL certs will be installed in an ELB, but all this could be modified for other environments).

Prerequisites

DNS should be configured for your domain. Create your hosted zone for your domain in Route 53, and make sure the domain is either registered there, or fully delegated from your registrar to Route 53.
Currently, your SSLMate account will need to be manually activated to use DNS approval.

It's recommended that you use a set of AWS credentials scoped to access just the things you need, rather than root credentials that could control your entire AWS account. Here's a list of IAM permissions needed:

route53:ListHostedZones on *
route53:GetChange on arn:aws:route53:::change/*
route53:ListResourceRecordSets on arn:aws:route53:::hostedzone/HOSTED_ZONE_ID
route53:ChangeResourceRecordSets on arn:aws:route53:::hostedzone/HOSTED_ZONE_ID
iam:ListServerCertificates on arn:aws:iam::ACCOUNT_ID:server-certificate/DOMAIN_NAME-sslmate/*
iam:UploadServerCertificate on arn:aws:iam::ACCOUNT_ID:server-certificate/DOMAIN_NAME-sslmate/*
iam:DeleteServerCertificate on arn:aws:iam::ACCOUNT_ID:server-certificate/DOMAIN_NAME-sslmate/*
elasticloadbalancing:SetLoadBalancerListenerSSLCertificate on arn:aws:elasticloadbalancing:REGION_NAME:ACCOUNT_ID:loadbalancer/LOAD_BALANCER_NAME

Configuration

Currently this relies on a beta version of SSLMate, so you must specify the git_revision (from the apiv2 branch). Specify the domains like this example:

{
  "run_list": [
    "recipe[sslmate::manage_domains]"
  ],
  "sslmate": {
    "git_revision": "2bc1946efdf5d80d333d6cc477dd74e6c8d42663",
    "domains": [
      {
        "host": "example.com",
        "elbs": [
          {
            "region": "us-east-1",
            "name": "example-lb"
          }
        ]
      }
    ]
  }
}

Installation & Management

Run chef: To install all the necessary dependencies.
First-time purchase: To purchase a new certificate, run this helper script that gets installed by Chef for your configured domains:

$ sudo /usr/local/sbin/sslmate_example.com_buy

It will prompt for your SSLMate and AWS credentials the first time it's run. It will then purchase the certificate and configure the defined ELBs to use it. 3. Tada! That should be all that's necessary. A cron job will also get installed in /etc/cron.daily/sslmate_example.com_auto_renew. This will automatically download and install a new SSL certificate on a yearly basis when SSLMate renews your cert.
