LetsEncrypt-Cloudflare

This role simplifies the process of renewing LetsEncrypt Certificates when utilising Cloudflare as a DNS provider.

Requirements

• Python >= 2.6
• OpenSSL (will automatically be installed if supported)

Role Variables

Available variables are listed below, along with default values (see defaults/main.yml for many more variables that can be modified)

Required Fields:

letsencrypt_email: ""
cloudflare_email: ""
cloudflare_api_key: "" # 'Global' API key for specified Cloudflare account
cloudflare_domain: "" # Cloudflare hosted DNS zone for entries to be created under

Important Notes:

By default, the role will use the inventory hostname as the Common Name to request a certificate, and place all generated/recieved certificate files in /etc/ssl/[Certificate Common Name], and all LetsEncrypt account files in /etc/ssl/lets_encrypt. These paths can all be overridden (see defaults/main.yml).

Furthermore, the certificate files can also be copied and renamed to another location after generation, by modifying any of the following variables:

copy_csr_full_path: ""
copy_crt_full_path: ""
copy_key_full_path: ""
copy_intermediate_full_path: "" # Requires include_intermediate set to 'yes'
copy_fullchain_full_path: "" # Requires include_intermediate set to 'yes'

The role also defaults to using the "staging" letsencrypt endpoints which will generate functionally correct yet untrusted certificates. In order to generate valid certificates, set:

letsencrypt_production: yes

Generated files can be removed after use by specifying the following variable:

cleanup_all: yes
